This list -contains machines that are ready to offer file and/or print services -to other machines within the network. Thus it does not include -machines which aren't currently able to do server tasks. The browse -list is heavily used by all SMB clients. Configuration of SMB -browsing has been problematic for some Samba users, hence this -document. - -Browsing will NOT work if name resolution from NetBIOS names to IP -addresses does not function correctly. Use of a WINS server is highly -recommended to aid the resolution of NetBIOS (SMB) names to IP addresses. -WINS allows remote segment clients to obtain NetBIOS name_type information -that can NOT be provided by any other means of name resolution. - -===================================================================== - -BROWSING -======== -Samba now fully supports browsing. The browsing is supported by nmbd -and is also controlled by options in the smb.conf file (see smb.conf(5)). - -Samba can act as a local browse master for a workgroup and the ability -for samba to support domain logons and scripts is now available. See -DOMAIN.txt for more information on domain logons. - -Samba can also act as a domain master browser for a workgroup. This -means that it will collate lists from local browse masters into a -wide area network server list. In order for browse clients to -resolve the names they may find in this list, it is recommended that -both samba and your clients use a WINS server. - -Note that you should NOT set Samba to be the domain master for a -workgroup that has the same name as an NT Domain: on each wide area -network, you must only ever have one domain master browser per workgroup, -regardless of whether it is NT, Samba or any other type of domain master -that is providing this service. - -[Note that nmbd can be configured as a WINS server, but it is not -necessary to specifically use samba as your WINS server. NTAS can -be configured as your WINS server. In a mixed NT server and -samba environment on a Wide Area Network, it is recommended that -you use the NT server's WINS server capabilities. In a samba-only -environment, it is recommended that you use one and only one nmbd -as your WINS server]. - -To get browsing to work you need to run nmbd as usual, but will need -to use the "workgroup" option in smb.conf to control what workgroup -Samba becomes a part of. - -Samba also has a useful option for a Samba server to offer itself for -browsing on another subnet. It is recommended that this option is only -used for 'unusual' purposes: announcements over the internet, for -example. See "remote announce" in the smb.conf man page. - -If something doesn't work then hopefully the log.nmb file will help -you track down the problem. Try a debug level of 2 or 3 for finding -problems. Also note that the current browse list usually gets stored -in text form in a file called browse.dat. - -Note that if it doesn't work for you, then you should still be able to -type the server name as \\SERVER in filemanager then hit enter and -filemanager should display the list of available shares. - -Some people find browsing fails because they don't have the global -"guest account" set to a valid account. Remember that the IPC$ -connection that lists the shares is done as guest, and thus you must -have a valid guest account. - -Also, a lot of people are getting bitten by the problem of too many -parameters on the command line of nmbd in inetd.conf. This trick is to -not use spaces between the option and the parameter (eg: -d2 instead -of -d 2), and to not use the -B and -N options. New versions of nmbd -are now far more likely to correctly find your broadcast and network -address, so in most cases these aren't needed. - -The other big problem people have is that their broadcast address, -netmask or IP address is wrong (specified with the "interfaces" option -in smb.conf) - - -BROWSING ACROSS SUBNETS -======================= - -With the release of Samba 1.9.17(alpha1 and above) Samba has been -updated to enable it to support the replication of browse lists -across subnet boundaries. New code and options have been added to -achieve this. This section describes how to set this feature up -in different settings. - -To see browse lists that span TCP/IP subnets (ie. networks separated -by routers that don't pass broadcast traffic) you must set up at least -one WINS server. The WINS server acts as a DNS for NetBIOS names, allowing -NetBIOS name to IP address translation to be done by doing a direct -query of the WINS server. This is done via a directed UDP packet on -port 137 to the WINS server machine. The reason for a WINS server is -that by default, all NetBIOS name to IP address translation is done -by broadcasts from the querying machine. This means that machines -on one subnet will not be able to resolve the names of machines on -another subnet without using a WINS server. - -Remember, for browsing across subnets to work correctly, all machines, -be they Windows 95, Windows NT, or Samba servers must have the IP address -of a WINS server given to them by a DHCP server, or by manual configuration -(for Win95 and WinNT, this is in the TCP/IP Properties, under Network -settings) for Samba this is in the smb.conf file. - -How does cross subnet browsing work ? -===================================== - -Cross subnet browsing is a complicated dance, containing multiple -moving parts. It has taken Microsoft several years to get the code -that achieves this correct, and Samba lags behind in some areas. -However, with the 1.9.17 release, Samba is capable of cross subnet -browsing when configured correctly. - -Consider a network set up as follows : - - (DMB) - N1_A N1_B N1_C N1_D N1_E - | | | | | - ------------------------------------------------------- - | subnet 1 | - +---+ +---+ - |R1 | Router 1 Router 2 |R2 | - +---+ +---+ - | | - | subnet 2 subnet 3 | - -------------------------- ------------------------------------ - | | | | | | | | - N2_A N2_B N2_C N2_D N3_A N3_B N3_C N3_D - (WINS) - -Consisting of 3 subnets (1, 2, 3) conneted by two routers -(R1, R2) - these do not pass broadcasts. Subnet 1 has 5 machines -on it, subnet 2 has 4 machines, subnet 3 has 4 machines. Assume -for the moment that all these machines are configured to be in the -same workgroup (for simplicities sake). Machine N1_C on subnet 1 -is configured as Domain Master Browser (ie. it will collate the -browse lists for the workgroup). Machine N2_D is configured as -WINS server and all the other machines are configured to register -their NetBIOS names with it. - -As all these machines are booted up, elections for master browsers -will take place on each of the three subnets. Assume that machine -N1_C wins on subnet 1, N2_B wins on subnet 2, and N3_D wins on -subnet 3 - these machines are known as local master browsers for -their particular subnet. N1_C has an advantage in winning as the -local master browser on subnet 1 as it is set up as Domain Master -Browser. - -On each of the three networks, machines that are configured to -offer sharing services will broadcast that they are offering -these services. The local master browser on each subnet will -receive these broadcasts and keep a record of the fact that -the machine is offering a service. This list of records is -the basis of the browse list. For this case, assume that -all the machines are configured to offer services so all machines -will be on the browse list. - -For each network, the local master browser on that network is -considered 'authoritative' for all the names it receives via -local broadcast. This is because a machine seen by the local -master browser via a local broadcast must be on the same -network as the local master browser and thus is a 'trusted' -and 'verifiable' resource. Machines on other networks that -the local master browsers learn about when collating their -browse lists have not been directly seen - these records are -called 'non-authoritative'. - -At this point the browse lists look as follows (these are -the machines you would see in your network neighborhood if -you looked in it on a particular network right now). - -Subnet Browse Master List ------- ------------- ---- -Subnet1 N1_C N1_A, N1_B, N1_C, N1_D, N1_E - -Subnet2 N2_B N2_A, N2_B, N2_C, N2_D - -Subnet3 N3_D N3_A, N3_B, N3_C, N3_D - -Note that at this point all the subnets are separate, no -machine is seen across any of the subnets. - -Now examine subnet 2. As soon as N2_B has become the local -master browser it looks for a Domain master browser to synchronize -its browse list with. It does this by querying the WINS server -(N2_D) for the IP address associated with the NetBIOS name -WORKGROUP<1B>. This name was registerd by the Domain master -browser (N1_C) with the WINS server as soon as it was booted. - -Once N2_B knows the address of the Domain master browser it -tells it that is the local master browser for subnet 2 by -sending a MasterAnnouncement packet as a UDP port 138 packet. -It then synchronizes with it by doing a NetServerEnum2 call. This -tells the Domain Master Browser to send it all the server -names it knows about. Once the domain master browser receives -the MasterAnnouncement packet it schedules a synchronization -request to the sender of that packet. After both synchronizations -are done the browse lists look like : - -Subnet Browse Master List ------- ------------- ---- -Subnet1 N1_C N1_A, N1_B, N1_C, N1_D, N1_E, - N2_A(*), N2_B(*), N2_C(*), N2_D(*) - -Subnet2 N2_B N2_A, N2_B, N2_C, N2_D - N1_A(*), N1_B(*), N1_C(*), N1_D(*), N1_E(*) - -Subnet3 N3_D N3_A, N3_B, N3_C, N3_D - -Servers with a (*) after them are non-authoritative names. - -At this point users looking in their network neighborhood on -subnets 1 or 2 will see all the servers on both, users on -subnet 3 will still only see the servers on their own subnet. - -The same sequence of events that occured for N2_B now occurs -for the local master browser on subnet 3 (N3_D). When it -synchronizes browse lists with the domain master browser (N1_A) -it gets both the server entries on subnet 1, and those on -subnet 2. After N3_D has synchronized with N1_C and vica-versa -the browse lists look like. - -Subnet Browse Master List ------- ------------- ---- -Subnet1 N1_C N1_A, N1_B, N1_C, N1_D, N1_E, - N2_A(*), N2_B(*), N2_C(*), N2_D(*), - N3_A(*), N3_B(*), N3_C(*), N3_D(*) - -Subnet2 N2_B N2_A, N2_B, N2_C, N2_D - N1_A(*), N1_B(*), N1_C(*), N1_D(*), N1_E(*) - -Subnet3 N3_D N3_A, N3_B, N3_C, N3_D - N1_A(*), N1_B(*), N1_C(*), N1_D(*), N1_E(*), - N2_A(*), N2_B(*), N2_C(*), N2_D(*) - -Servers with a (*) after them are non-authoritative names. - -At this point users looking in their network neighborhood on -subnets 1 or 3 will see all the servers on all sunbets, users on -subnet 2 will still only see the servers on subnets 1 and 2, but not 3. - -Finally, the local master browser for subnet 2 (N2_B) will sync again -with the domain master browser (N1_C) and will recieve the missing -server entries. Finally - and as a steady state (if no machines -are removed or shut off) the browse lists will look like : - -Subnet Browse Master List ------- ------------- ---- -Subnet1 N1_C N1_A, N1_B, N1_C, N1_D, N1_E, - N2_A(*), N2_B(*), N2_C(*), N2_D(*), - N3_A(*), N3_B(*), N3_C(*), N3_D(*) - -Subnet2 N2_B N2_A, N2_B, N2_C, N2_D - N1_A(*), N1_B(*), N1_C(*), N1_D(*), N1_E(*) - N3_A(*), N3_B(*), N3_C(*), N3_D(*) - -Subnet3 N3_D N3_A, N3_B, N3_C, N3_D - N1_A(*), N1_B(*), N1_C(*), N1_D(*), N1_E(*), - N2_A(*), N2_B(*), N2_C(*), N2_D(*) - -Servers with a (*) after them are non-authoritative names. - -Synchronizations between the domain master browser and local -master browsers will continue to occur, but this should be a -steady state situation. - -If either router R1 or R2 fails the following will occur: - -1) Names of computers on each side of the inaccessible network fragments -will be maintained for as long as 36 minutes, in the network neighbourhood -lists. - -2) Attempts to connect to these inaccessible computers will fail, but the -names will not be removed from the network neighbourhood lists. - -3) If one of the fragments is cut off from the WINS server, it will only -be able to access servers on its local subnet, by using subnet-isolated -broadcast NetBIOS name resolution. The effects are similar to that of -losing access to a DNS server. - -Setting up a WINS server -======================== - -Either a Samba machine or a Windows NT Server machine may be set up -as a WINS server. To set a Samba machine to be a WINS server you must -add the following option to the smb.conf file on the selected machine : -in the [globals] section add the line - - wins support = yes - -Versions of Samba previous to 1.9.17 had this parameter default to -yes. If you have any older versions of Samba on your network it is -strongly suggested you upgrade to 1.9.17 or above, or at the very -least set the parameter to 'no' on all these machines. - -Machines with "wins support = yes" will keep a list of all NetBIOS -names registered with them, acting as a DNS for NetBIOS names. - -You should set up only ONE wins server. Do NOT set the -"wins support = yes" option on more than one Samba server. - -To set up a Windows NT Server as a WINS server you need to set up -the WINS service - see your NT documentation for details. Note that -Windows NT WINS Servers can replicate to each other, allowing more -than one to be set up in a complex subnet environment. As Microsoft -refuse to document these replication protocols Samba cannot currently -participate in these replications. It is possible in the future that -a Samba->Samba WINS replication protocol may be defined, in which -case more than one Samba machine could be set up as a WINS server -but currently only one Samba server should have the "wins support = yes" -parameter set. - -After the WINS server has been configured you must ensure that all -machines participating on the network are configured with the address -of this WINS server. If your WINS server is a Samba machine, fill in -the Samba machine IP address in the "Primary WINS Server" field of -the "Control Panel->Network->Protocols->TCP->WINS Server" dialogs -in Windows 95 or Windows NT. To tell a Samba server the IP address -of the WINS server add the following line to the [global] section of -all smb.conf files : - - wins server = - -where is either the DNS name of the WINS server -machine or its IP address. - -Note that this line MUST NOT BE SET in the smb.conf file of the Samba -server acting as the WINS server itself. If you set both the -"wins support = yes" option and the "wins server = " option then -nmbd will fail to start. - -There are two possible scenarios for setting up cross subnet browsing. -The first details setting up cross subnet browsing on a network containing -Windows 95, Samba and Windows NT machines that are not configured as -part of a Windows NT Domain. The second details setting up cross subnet -browsing on networks that contain NT Domains. - -Setting up Browsing in a WORKGROUP -================================== - -To set up cross subnet browsing on a network containing machines -in up to be in a WORKGROUP, not an NT Domain you need to set up one -Samba server to be the Domain Master Browser (note that this is *NOT* -the same as a Primary Domain Controller, although in an NT Domain the -same machine plays both roles). The role of a Domain master browser is -to collate the browse lists from local master browsers on all the -subnets that have a machine participating in the workgroup. Without -one machine configured as a domain master browser each subnet would -be an isolated workgroup, unable to see any machines on any other -subnet. It is the presense of a domain master browser that makes -cross subnet browsing possible for a workgroup. - -In an WORKGROUP environment the domain master browser must be a -Samba server, and there must only be one domain master browser per -workgroup name. To set up a Samba server as a domain master browser, -set the following option in the [global] section of the smb.conf file : - - domain master = yes - -The domain master browser should also preferrably be the local master -browser for its own subnet. In order to achieve this set the following -options in the [global] section of the smb.conf file : - - domain master = yes - local master = yes - preferred master = yes - os level = 65 - -The domain master browser may be the same machine as the WINS -server, if you require. - -Next, you should ensure that each of the subnets contains a -machine that can act as a local master browser for the -workgroup. Any NT machine should be able to do this, as will -Windows 95 machines (although these tend to get rebooted more -often, so it's not such a good idea to use these). To make a -Samba server a local master browser set the following -options in the [global] section of the smb.conf file : - - domain master = no - local master = yes - preferred master = yes - os level = 65 - -Do not do this for more than one Samba server on each subnet, -or they will war with each other over which is to be the local -master browser. - -The "local master" parameter allows Samba to act as a local master -browser. The "preferred master" causes nmbd to force a browser -election on startup and the "os level" parameter sets Samba high -enough so that it should win any browser elections. - -If you have an NT machine on the subnet that you wish to -be the local master browser then you can disable Samba from -becoming a local master browser by setting the following -options in the [global] section of the smb.conf file : - - domain master = no - local master = no - preferred master = no - os level = 0 - -Setting up Browsing in a DOMAIN -=============================== - -If you are adding Samba servers to a Windows NT Domain then -you must not set up a Samba server as a domain master browser. -By default, a Windows NT Primary Domain Controller for a Domain -name is also the Domain master browser for that name, and many -things will break if a Samba server registers the Domain master -browser NetBIOS name (DOMAIN<1B>) with WINS instead of the PDC. - -For subnets other than the one containing the Windows NT PDC -you may set up Samba servers as local master browsers as -described. To make a Samba server a local master browser set -the following options in the [global] section of the smb.conf -file : - - domain master = no - local master = yes - preferred master = yes - os level = 65 - -If you wish to have a Samba server fight the election with machines -on the same subnet you may set the "os level" parameter to lower -levels. By doing this you can tune the order of machines that -will become local master browsers if they are running. For -more details on this see the section "FORCING SAMBA TO BE THE MASTER" -below. - -If you have Windows NT machines that are members of the domain -on all subnets, and you are sure they will always be running then -you can disable Samba from taking part in browser elections and -ever becoming a local master browser by setting following options -in the [global] section of the smb.conf file : - - domain master = no - local master = no - preferred master = no - os level = 0 - -FORCING SAMBA TO BE THE MASTER -============================== - -Who becomes the "master browser" is determined by an election process -using broadcasts. Each election packet contains a number of parameters -which determine what precedence (bias) a host should have in the -election. By default Samba uses a very low precedence and thus loses -elections to just about anyone else. - -If you want Samba to win elections then just set the "os level" global -option in smb.conf to a higher number. It defaults to 0. Using 34 -would make it win all elections over every other system (except other -samba systems!) - -A "os level" of 2 would make it beat WfWg and Win95, but not NTAS. A -NTAS domain controller uses level 32. - -The maximum os level is 255 - -If you want samba to force an election on startup, then set the -"preferred master" global option in smb.conf to "yes". Samba will -then have a slight advantage over other potential master browsers -that are not preferred master browsers. Use this parameter with -care, as if you have two hosts (whether they are windows 95 or NT or -samba) on the same local subnet both set with "preferred master" to -"yes", then periodically and continually they will force an election -in order to become the local master browser. - -If you want samba to be a "domain master browser", then it is -recommended that you also set "preferred master" to "yes", because -samba will not become a domain master browser for the whole of your -LAN or WAN if it is not also a local master browser on its own -broadcast isolated subnet. - -It is possible to configure two samba servers to attempt to become -the domain master browser for a domain. The first server that comes -up will be the domain master browser. All other samba servers will -attempt to become the domain master browser every 5 minutes. They -will find that another samba server is already the domain master -browser and will fail. This provides automatic redundancy, should -the current domain master browser fail. - - -MAKING SAMBA THE DOMAIN MASTER -============================== - -The domain master is responsible for collating the browse lists of -multiple subnets so that browsing can occur between subnets. You can -make samba act as the domain master by setting "domain master = yes" -in smb.conf. By default it will not be a domain master. - -Note that you should NOT set Samba to be the domain master for a -workgroup that has the same name as an NT Domain. - -When samba is the domain master and the master browser it will listen -for master announcements (made roughly every twelve minutes) from local -master browsers on other subnets and then contact them to synchronise -browse lists. - -If you want samba to be the domain master then I suggest you also set -the "os level" high enough to make sure it wins elections, and set -"preferred master" to "yes", to get samba to force an election on -startup. - -Note that all your servers (including samba) and clients should be -using a WINS server to resolve NetBIOS names. If your clients are only -using broadcasting to resolve NetBIOS names, then two things will occur: - -a) your local master browsers will be unable to find a domain master - browser, as it will only be looking on the local subnet. - -b) if a client happens to get hold of a domain-wide browse list, and - a user attempts to access a host in that list, it will be unable to - resolve the NetBIOS name of that host. - -If, however, both samba and your clients are using a WINS server, then: - -a) your local master browsers will contact the WINS server and, as long as - samba has registered that it is a domain master browser with the WINS - server, your local master browser will receive samba's ip address - as its domain master browser. - -b) when a client receives a domain-wide browse list, and a user attempts - to access a host in that list, it will contact the WINS server to - resolve the NetBIOS name of that host. as long as that host has - registered its NetBIOS name with the same WINS server, the user will - be able to see that host. - -NOTE ABOUT BROADCAST ADDRESSES -============================== - -If your network uses a "0" based broadcast address (for example if it -ends in a 0) then you will strike problems. Windows for Workgroups -does not seem to support a 0's broadcast and you will probably find -that browsing and name lookups won't work. - - -MULTIPLE INTERFACES -=================== - -Samba now supports machines with multiple network interfaces. If you -have multiple interfaces then you will need to use the "interfaces" -option in smb.conf to configure them. See smb.conf(5) for details. - diff --git a/docs/textdocs/BUGS.txt b/docs/textdocs/BUGS.txt deleted file mode 100644 index 247998c6c7..0000000000 --- a/docs/textdocs/BUGS.txt +++ /dev/null @@ -1,135 +0,0 @@ -Contributor: Samba Team -Updated: June 27, 1997 - -Subject: This file describes how to report Samba bugs. -============================================================================ - ->> The email address for bug reports is samba@samba.org << - -Please take the time to read this file before you submit a bug -report.

It is probably a -segmentation fault and almost certainly means a bug in Samba (unless -you have faulty hardware or system software) - -If the message came from smbd then it will probably be accompanied by -a message which details the last SMB message received by smbd. This -info is often very useful in tracking down the problem so please -include it in your bug report. - -You should also detail how to reproduce the problem, if -possible. Please make this reasonably detailed. - -You may also find that a core file appeared in a "corefiles" -subdirectory of the directory where you keep your samba log -files. This file is the most useful tool for tracking down the bug. To -use it you do this: - -gdb smbd core - -adding appropriate paths to smbd and core so gdb can find them. If you -don't have gdb then try "dbx". Then within the debugger use the -command "where" to give a stack trace of where the problem -occurred. Include this in your mail. - -If you known any assembly language then do a "disass" of the routine -where the problem occurred (if its in a library routine then -disassemble the routine that called it) and try to work out exactly -where the problem is by looking at the surrounding code. Even if you -don't know assembly then incuding this info in the bug report can be -useful. - - -ATTACHING TO A RUNNING PROCESS ------------------------------- - -Unfortunately some unixes (in particular some recent linux kernels) -refuse to dump a core file if the task has changed uid (which smbd -does often). To debug with this sort of system you could try to attach -to the running process using "gdb smbd PID" where you get PID from -smbstatus. Then use "c" to continue and try to cause the core dump -using the client. The debugger should catch the fault and tell you -where it occurred. - - -PATCHES -------- - -The best sort of bug report is one that includes a fix!

The -best way to check this is with "testparm smb.conf" - - -TEST 1: -------- - -In the directory in which you store your smb.conf file, run the command -"testparm smb.conf". If it reports any errors then your smb.conf -configuration file is faulty. - -Note: Your smb.conf file may be located in: /etc - Or in: /usr/local/samba/lib - - -TEST 2: -------- - -run the command "ping BIGSERVER" from the PC and "ping ACLIENT" from -the unix box. If you don't get a valid response then your TCP/IP -software is not correctly installed. - -Note that you will need to start a "dos prompt" window on the PC to -run ping. - -If you get a message saying "host not found" or similar then your DNS -software or /etc/hosts file is not correctly setup. It is possible to -run samba without DNS entries for the server and client, but I assume -you do have correct entries for the remainder of these tests. - -Another reason why ping might fail is if your host is running firewall -software. You will need to relax the rules to let in the workstation -in question, perhaps by allowing access from another subnet (on Linux -this is done via the ipfwadm program.) - - -TEST 3: -------- - -Run the command "smbclient -L BIGSERVER" on the unix box. You -should get a list of available shares back. - -If you get a error message containing the string "Bad password" then -you probably have either an incorrect "hosts allow", "hosts deny" or -"valid users" line in your smb.conf, or your guest account is not -valid.

If you installed it as a daemon then check that -it is running, and check that the netbios-ssn port is in a LISTEN -state using "netstat -a". - -If you get a "session request failed" then the server refused the -connection. If it says "Your server software is being unfriendly" then -its probably because you have invalid command line parameters to smbd, -or a similar fatal problem with the initial startup of smbd. Also -check your config file (smb.conf) for syntax errors with "testparm" -and that the various directories where samba keeps its log and lock -files exist. - -There are a number of reasons for which smbd may refuse or decline -a session request. The most common of these involve one or more of -the following smb.conf file entries: - hosts deny = ALL - hosts allow = xxx.xxx.xxx.xxx/yy - bind interfaces only = Yes - -In the above, no allowance has been made for any session requests that -will automatically translate to the loopback adaptor address 127.0.0.1. -To solve this problem change these lines to: - hosts deny = ALL - hosts allow = xxx.xxx.xxx.xxx/yy 127. -Do NOT use the "bind interfaces only" parameter where you may wish to -use the samba password change facility, or where smbclient may need to -access local service for name resolution or for local resource -connections. (Note: the "bind interfaces only" parameter deficiency -where it will not allow connections to the loopback address will be -fixed soon). - -Another common cause of these two errors is having something already running -on port 139, such as Samba (ie: smbd is running from inetd already) or -something like Digital's Pathworks. Check your inetd.conf file before trying -to start smbd as a daemon, it can avoid a lot of frustration! - -And yet another possible cause for failure of TEST 3 is when the subnet mask -and / or broadcast address settings are incorrect. Please check that the -network interface IP Address / Broadcast Address / Subnet Mask settings are -correct and that Samba has correctly noted these in the log.nmb file. - -TEST 4: -------- - -Run the command "nmblookup -B BIGSERVER __SAMBA__". You should get the -IP address of your Samba server back. - -If you don't then nmbd is incorrectly installed. Check your inetd.conf -if you run it from there, or that the daemon is running and listening -to udp port 137. - -One common problem is that many inetd implementations can't take many -parameters on the command line. If this is the case then create a -one-line script that contains the right parameters and run that from -inetd. - - -TEST 5: -------- - -run the command "nmblookup -B ACLIENT '*'" - -You should get the PCs IP address back. If you don't then the client -software on the PC isn't installed correctly, or isn't started, or you -got the name of the PC wrong. - -If ACLIENT doesn't resolve via DNS then use the IP address of the -client in the above test. - - -TEST 6: -------- - -Run the command "nmblookup -d 2 '*'" - -This time we are trying the same as the previous test but are trying -it via a broadcast to the default broadcast address. A number of -Netbios/TCPIP hosts on the network should respond, although Samba may -not catch all of the responses in the short time it listens. You -should see "got a positive name query response" messages from several -hosts. - -If this doesn't give a similar result to the previous test then -nmblookup isn't correctly getting your broadcast address through its -automatic mechanism. In this case you should experiment use the -"interfaces" option in smb.conf to manually configure your IP -address, broadcast and netmask. - -If your PC and server aren't on the same subnet then you will need to -use the -B option to set the broadcast address to the that of the PCs -subnet. - -This test will probably fail if your subnet mask and broadcast address are -not correct. (Refer to TEST 3 notes above). - -TEST 7: -------- - -Run the command "smbclient //BIGSERVER/TMP". You should then be -prompted for a password. You should use the password of the account -you are logged into the unix box with.

If you -don't then look at the error message. If it says "invalid network -name" then the service "tmp" is not correctly setup in your smb.conf. - -If it says "bad password" then the likely causes are: - -- you have shadow passords (or some other password system) but didn't -compile in support for them in smbd -- your "valid users" configuration is incorrect -- you have a mixed case password and you haven't enabled the "password -level" option at a high enough level -- the "path =" line in smb.conf is incorrect. Check it with testparm -- you enabled password encryption but didn't create the SMB encrypted -password file - -Once connected you should be able to use the commands "dir" "get" -"put" etc. Type "help " for instructions. You should -especially check that the amount of free disk space shown is correct -when you type "dir". - - -TEST 8: -------- - -On the PC type the command "net view \\BIGSERVER". You will need to do -this from within a "dos prompt" window. You should get back a list of -available shares on the server. - -If you get a "network name not found" or similar error then netbios -name resolution is not working. This is usually caused by a problem in -nmbd. To overcome it you could do one of the following (you only need -to choose one of them): - -- fixup the nmbd installation -- add the IP address of BIGSERVER to the "wins server" box in the -advanced tcp/ip setup on the PC. -- enable windows name resolution via DNS in the advanced section of -the tcp/ip setup -- add BIGSERVER to your lmhosts file on the PC. - -If you get a "invalid network name" or "bad password error" then the -same fixes apply as they did for the "smbclient -L" test above. In -particular, make sure your "hosts allow" line is correct (see the man -pages) - -Also, do not overlook that fact that when the workstation requests the -connection to the samba server it will attempt to connect using the -name with which you logged onto your Windows machine. You need to make -sure that an account exists on your Samba server with that exact same -name and password. - -If you get "specified computer is not receiving requests" or similar -it probably means that the host is not contactable via tcp services. -Check to see if the host is running tcp wrappers, and if so add an entry in -the hosts.allow file for your client (or subnet, etc.) - - -TEST 9: --------- - -Run the command "net use x: \\BIGSERVER\TMP". You should be prompted -for a password then you should get a "command completed successfully" -message. If not then your PC software is incorrectly installed or your -smb.conf is incorrect. make sure your "hosts allow" and other config -lines in smb.conf are correct. - -It's also possible that the server can't work out what user name to -connect you as. To see if this is the problem add the line "user = -USERNAME" to the [tmp] section of smb.conf where "USERNAME" is the -username corresponding to the password you typed. If you find this -fixes things you may need the username mapping option. - -TEST 10: --------- - -Run the command "nmblookup -M TESTGROUP" where TESTGROUP is the name -of the workgroup that your Samba server and Windows PCs belong to. You -should get back the IP address of the master browser for that -workgroup. - -If you don't then the election process has failed. Wait a minute to -see if it is just being slow then try again.

Other WINS clients will then -contact the WINS server to resolve a NetBIOS name. - - -======================= -Samba WINS Capabilities -======================= - -To configure samba as a WINS server, you must add "wins support = yes" to -the [global] section of your smb.conf file. This will enable WINS server -capabilities in nmbd. - -To configure samba as a WINS client, you must add "wins server = x.x.x.x" -to the [global] section of your smb.conf file, where x.x.x.x is the TCP/IP -address of your WINS server. The browsing capabilities in nmbd will then -register (and resolve) WAN-wide NetBIOS names with this WINS server. - -Note that if samba has "wins support = yes", then the browsing capabilities -will _not_ use the "wins server" option to resolve NetBIOS names: it will -go directly to the internal WINS database for NetBIOS name resolution. It -is therefore invalid to have both "wins support = yes" and -"wins server = x.x.x.x". Note, in particular, that if you configure the -"wins server" parameter to be the ip address of your samba server itself -(as might one intuitively think), that you will run into difficulties. -Do not use both parameters! - - diff --git a/docs/textdocs/Printing.txt b/docs/textdocs/Printing.txt deleted file mode 100644 index 2c50e5f4fe..0000000000 --- a/docs/textdocs/Printing.txt +++ /dev/null @@ -1,255 +0,0 @@ -Contributor: Unknown -Revised by: Patrick Powell -Date: August 11, 2000 -Status: Current - -Subject: Debugging Printing Problems -============================================================================= - -This is a short description of how to debug printing problems with -Samba. This describes how to debug problems with printing from a SMB -client to a Samba server, not the other way around. For the reverse -see the examples/printing directory. - -Please send enhancements to this file to samba@samba.org - -Ok, so you want to print to a Samba server from your PC. The first -thing you need to understand is that Samba does not actually do any -printing itself, it just acts as a middleman between your PC client -and your Unix printing subsystem. Samba receives the file from the PC -then passes the file to a external "print command". What print command -you use is up to you. - -The whole things is controlled using options in smb.conf. The most -relevant options (which you should look up in the smb.conf man page) -are: - [global] - print command - send a file to a spooler - lpq command - get spool queue status - lprm command - remove a job - [printers] - path = /var/spool/lpd/samba - -The following are nice to know about: - - queuepause command - stop a printer or print queue - queueresume command - start a printer or print queue - -Example: - print command = /usr/bin/lpr -r -P%p %s - lpq command = /usr/bin/lpq -P%p %s - lprm command = /usr/bin/lprm -P%p %j - queuepause command = /usr/sbin/lpc -P%p stop - queuepause command = /usr/sbin/lpc -P%p start - -Samba should set reasonable defaults for these depending on your -system type, but it isn't clairvoyant. It is not uncommon that you -have to tweak these for local conditions. The commands should -always have fully specified pathnames, as the smdb may not have -the correct PATH values. - -When you send a job to Samba to be printed, it will make a temporary -copy of it in the directory specified in the [printers] section. -and it should be periodically cleaned out. The lpr -r option -requests that the temporary copy be removed after printing; If -printing fails then you might find leftover files in this directory, -and it should be periodically cleaned out. Samba used the lpq -command to determine the "job number" assigned to your print job -by the spooler. - -The % are "macros" that get dynamically replaced with appropriate -values when they are used. The %s gets replaced with the name of the spool -file that Samba creates and the %p gets replaced with the name of the -printer. The %j gets replaced with the "job number" which comes from -the lpq output. - -DEBUGGING PRINTER PROBLEMS - -One way to debug printing problems is to start by replacing these -command with shell scripts that record the arguments and the contents -of the print file. A simple example of this kind of things might -be: - - print command = /tmp/saveprint %p %s - - #!/bin/saveprint - # we make sure that we are the right user - /usr/bin/id -p >/tmp/tmp.print - # we run the command and save the error messages - # replace the command with the one appropriate for your system - /usr/bin/lpr -r -P$1 $2 2>>&/tmp/tmp.print - -Then you print a file and try removing it. You may find that the -print queue needs to be stopped in order to see the queue status -and remove the job: - -h4: {42} % echo hi >/tmp/hi -h4: {43} % smbclient //localhost/lw4 -added interface ip=10.0.0.4 bcast=10.0.0.255 nmask=255.255.255.0 -Password: -Domain=[ASTART] OS=[Unix] Server=[Samba 2.0.7] -smb: \> print /tmp/hi -putting file /tmp/hi as hi-17534 (0.0 kb/s) (average 0.0 kb/s) -smb: \> queue -1049 3 hi-17534 -smb: \> cancel 1049 -Error cancelling job 1049 : code 0 -smb: \> cancel 1049 -Job 1049 cancelled -smb: \> queue -smb: \> exit - -The 'code 0' indicates that the job was removed. The comment -by the smbclient is a bit misleading on this. -You can observe the command output and then and look at the -/tmp/tmp.print file to see what the results are. You can quickly -find out if the problem is with your printing system. Often people -have problems with their /etc/printcap file or permissions on -various print queues. - -WHAT PRINTERS DO I HAVE - -You can use the 'testprns' program to check to see if the printer -name you are using is recognized by Samba. For example, you can -use: - - testprns printer /etc/printcap - -Samba can get its printcap information from a file or from a program. -You can try the following to see the format of the extracted -information: - - testprns -a printer /etc/printcap - - testprns -a printer '|/bin/cat printcap' - -SETTING UP PRINTCAP AND PRINT SERVERS - -You may need to set up some printcaps for your Samba system to use. -It is strongly recommended that you use the facilities provided by -the print spooler to set up queues and printcap information. - -Samba requires either a printcap or program to deliver printcap -information. This printcap information has the format: - - name|alias1|alias2...:option=value:... - -For almost all printing systems, the printer 'name' must be composed -only of alphanumeric or underscore '_' characters. Some systems also -allow hyphens ('-') as well. An alias is an alternative name for the -printer, and an alias with a space in it is used as a 'comment' -about the printer. The printcap format optionally uses a \ at the end of lines -to extend the printcap to multiple lines. - - -Here are some examples of printcap files: - -pr just printer name -pr|alias printer name and alias -pr|My Printer printer name, alias used as comment -pr:sh:\ Same as pr:sh:cm= testing - :cm= \ - testing -pr:sh Same as pr:sh:cm= testing - :cm= testing - -Samba reads the printcap information when first started. If you make -changes in the printcap information, then you must do the following: - -a) make sure that the print spooler is aware of these changes. - The LPRng system uses the 'lpc reread' command to do this. - -b) make sure that the spool queues, etc., exist and have the - correct permissions. The LPRng system uses the 'checkpc -f' - command to do this. - -c) You now should send a SIGHUP signal to the smbd server to have - it reread the printcap information. - -JOB SENT, NO OUTPUT - -This is the most frustrating part of printing. You may have sent the -job, verified that the job was forwarded, set up a wrapper around -the command to send the file, but there was no output from the printer. - -First, check to make sure that the job REALLY is getting to the -right print queue. If you are using a BSD or LPRng print spooler, -you can temporarily stop the printing of jobs. Jobs can still be -submitted, but they will not be printed. Use: - - lpc -Pprinter stop - -Now submit a print job and then use 'lpq -Pprinter' to see if the -job is in the print queue. If it is not in the print queue then -you will have to find out why it is not being accepted for printing. - -Next, you may want to check to see what the format of the job really -was. With the assistance of the system administrator you can view -the submitted jobs files. You may be surprised to find that these -are not in what you would expect to call a printable format. -You can use the UNIX 'file' utitily to determine what the job -format actually is: - - cd /var/spool/lpd/printer # spool directory of print jobs - ls # find job files - file dfA001myhost - -You should make sure that your printer supports this format OR that -your system administrator has installed a 'print filter' that will -convert the file to a format appropriate for your printer. - -JOB SENT, STRANGE OUTPUT - -Once you have the job printing, you can then start worrying about -making it print nicely. - -The most common problem is extra pages of output: banner pages -OR blank pages at the end. - -If you are getting banner pages, check and make sure that the -printcap option or printer option is configured for no banners. -If you have a printcap, this is the :sh (suppress header or banner -page) option. You should have the following in your printer. - - printer: ... :sh - -If you have this option and are still getting banner pages, there -is a strong chance that your printer is generating them for you -automatically. You should make sure that banner printing is disabled -for the printer. This usually requires using the printer setup software -or procedures supplied by the printer manufacturer. - -If you get an extra page of output, this could be due to problems -with your job format, or if you are generating PostScript jobs, -incorrect setting on your printer driver on the MicroSoft client. -For example, under Win95 there is a option: - - Printers|Printer Name|(Right Click)Properties|Postscript|Advanced| - -that allows you to choose if a Ctrl-D is appended to all jobs. -This is a very bad thing to do, as most spooling systems will -automatically add a ^D to the end of the job if it is detected as -PostScript. The multiple ^D may cause an additional page of output. - -RAW POSTSCRIPT PRINTED - -This is a problem that is usually caused by either the print spooling -system putting information at the start of the print job that makes -the printer think the job is a text file, or your printer simply -does not support PostScript. You may need to enable 'Automatic -Format Detection' on your printer. - -ADVANCED PRINTING - -Note that you can do some pretty magic things by using your -imagination with the "print command" option and some shell scripts. -Doing print accounting is easy by passing the %U option to a print -command shell script. You could even make the print command detect -the type of output and its size and send it to an appropriate -printer. - -DEBUGGING - -If the above debug tips don't help, then maybe you need to bring in -the bug guns, system tracing.

Thus if you are -trying to see if it performs well you should really compare it to -programs that use the same protocol. The most readily available -programs for file transfer that use TCP are ftp or another TCP based -SMB server. - -If you want to test against something like a NT or WfWg server then -you will have to disable all but TCP on either the client or -server. Otherwise you may well be using a totally different protocol -(such as Netbeui) and comparisons may not be valid. - -Generally you should find that Samba performs similarly to ftp at raw -transfer speed. It should perform quite a bit faster than NFS, -although this very much depends on your system. - -Several people have done comparisons between Samba and Novell, NFS or -WinNT. In some cases Samba performed the best, in others the worst. I -suspect the biggest factor is not Samba vs some other system but the -hardware and drivers used on the various systems. Given similar -hardware Samba should certainly be competitive in speed with other -systems. - - -OPLOCKS -------- - -Oplocks are the way that SMB clients get permission from a server to -locally cache file operations. If a server grants an oplock -(opportunistic lock) then the client is free to assume that it is the -only one accessing the file and it will agressively cache file -data. With some oplock types the client may even cache file open/close -operations. This can give enormous performance benefits. - -With the release of Samba 1.9.18 we now correctly support opportunistic -locks. This is turned on by default, and can be turned off on a share- -by-share basis by setting the parameter : - -oplocks = False - -We recommend that you leave oplocks on however, as current benchmark -tests with NetBench seem to give approximately a 30% improvement in -speed with them on. This is on average however, and the actual -improvement seen can be orders of magnitude greater, depending on -what the client redirector is doing. - -Previous to Samba 1.9.18 there was a 'fake oplocks' option. This -option has been left in the code for backwards compatibility reasons -but it's use is now deprecated. A short summary of what the old -code did follows. - -LEVEL2 OPLOCKS --------------- - -With Samba 2.0.5 a new capability - level2 (read only) oplocks is -supported (although the option is off by default - see the smb.conf -man page for details). Turning on level2 oplocks (on a share-by-share basis) -by setting the parameter : - -level2 oplocks = true - -should speed concurrent access to files that are not commonly written -to, such as application serving shares (ie. shares that contain common -.EXE files - such as a Microsoft Office share) as it allows clients to -read-ahread cache copies of these files. - -Old 'fake oplocks' option - deprecated. ---------------------------------------- - -Samba can also fake oplocks, by granting a oplock whenever a client -asks for one. This is controlled using the smb.conf option "fake -oplocks". If you set "fake oplocks = yes" then you are telling the -client that it may agressively cache the file data for all opens. - -Enabling 'fake oplocks' on all read-only shares or shares that you know -will only be accessed from one client at a time you will see a big -performance improvement on many operations. If you enable this option -on shares where multiple clients may be accessing the files read-write -at the same time you can get data corruption. - -SOCKET OPTIONS --------------- - -There are a number of socket options that can greatly affect the -performance of a TCP based server like Samba. - -The socket options that Samba uses are settable both on the command -line with the -O option, or in the smb.conf file. - -The "socket options" section of the smb.conf manual page describes how -to set these and gives recommendations. - -Getting the socket options right can make a big difference to your -performance, but getting them wrong can degrade it by just as -much. The correct settings are very dependent on your local network. - -The socket option TCP_NODELAY is the one that seems to make the -biggest single difference for most networks. Many people report that -adding "socket options = TCP_NODELAY" doubles the read performance of -a Samba drive. The best explanation I have seen for this is that the -Microsoft TCP/IP stack is slow in sending tcp ACKs. - - -READ SIZE ---------- - -The option "read size" affects the overlap of disk reads/writes with -network reads/writes. If the amount of data being transferred in -several of the SMB commands (currently SMBwrite, SMBwriteX and -SMBreadbraw) is larger than this value then the server begins writing -the data before it has received the whole packet from the network, or -in the case of SMBreadbraw, it begins writing to the network before -all the data has been read from disk. - -This overlapping works best when the speeds of disk and network access -are similar, having very little effect when the speed of one is much -greater than the other. - -The default value is 16384, but very little experimentation has been -done yet to determine the optimal value, and it is likely that the best -value will vary greatly between systems anyway. A value over 65536 is -pointless and will cause you to allocate memory unnecessarily. - - -MAX XMIT --------- - -At startup the client and server negotiate a "maximum transmit" size, -which limits the size of nearly all SMB commands. You can set the -maximum size that Samba will negotiate using the "max xmit = " option -in smb.conf. Note that this is the maximum size of SMB request that -Samba will accept, but not the maximum size that the *client* will accept. -The client maximum receive size is sent to Samba by the client and Samba -honours this limit. - -It defaults to 65536 bytes (the maximum), but it is possible that some -clients may perform better with a smaller transmit unit. Trying values -of less than 2048 is likely to cause severe problems. - -In most cases the default is the best option. - - -LOCKING -------- - -By default Samba does not implement strict locking on each read/write -call (although it did in previous versions). If you enable strict -locking (using "strict locking = yes") then you may find that you -suffer a severe performance hit on some systems. - -The performance hit will probably be greater on NFS mounted -filesystems, but could be quite high even on local disks. - - -SHARE MODES ------------ - -Some people find that opening files is very slow. This is often -because of the "share modes" code needed to fully implement the dos -share modes stuff. You can disable this code using "share modes = -no". This will gain you a lot in opening and closing files but will -mean that (in some cases) the system won't force a second user of a -file to open the file read-only if the first has it open -read-write. For many applications that do their own locking this -doesn't matter, but for some it may. Most Windows applications -depend heavily on "share modes" working correctly and it is -recommended that the Samba share mode support be left at the -default of "on". - -The share mode code in Samba has been re-written in the 1.9.17 -release following tests with the Ziff-Davis NetBench PC Benchmarking -tool. It is now believed that Samba 1.9.17 implements share modes -similarly to Windows NT. - -NOTE: In the most recent versions of Samba there is an option to use -shared memory via mmap() to implement the share modes. This makes -things much faster. See the Makefile for how to enable this. - - -LOG LEVEL ---------- - -If you set the log level (also known as "debug level") higher than 2 -then you may suffer a large drop in performance. This is because the -server flushes the log file after each operation, which can be very -expensive. - - -WIDE LINKS ----------- - -The "wide links" option is now enabled by default, but if you disable -it (for better security) then you may suffer a performance hit in -resolving filenames. The performance loss is lessened if you have -"getwd cache = yes", which is now the default. - - -READ RAW --------- - -The "read raw" operation is designed to be an optimised, low-latency -file read operation. A server may choose to not support it, -however. and Samba makes support for "read raw" optional, with it -being enabled by default. - -In some cases clients don't handle "read raw" very well and actually -get lower performance using it than they get using the conventional -read operations. - -So you might like to try "read raw = no" and see what happens on your -network. It might lower, raise or not affect your performance. Only -testing can really tell. - - -WRITE RAW ---------- - -The "write raw" operation is designed to be an optimised, low-latency -file write operation. A server may choose to not support it, -however. and Samba makes support for "write raw" optional, with it -being enabled by default. - -Some machines may find "write raw" slower than normal write, in which -case you may wish to change this option. - -READ PREDICTION ---------------- - -Samba can do read prediction on some of the SMB commands. Read -prediction means that Samba reads some extra data on the last file it -read while waiting for the next SMB command to arrive. It can then -respond more quickly when the next read request arrives. - -This is disabled by default. You can enable it by using "read -prediction = yes". - -Note that read prediction is only used on files that were opened read -only. - -Read prediction should particularly help for those silly clients (such -as "Write" under NT) which do lots of very small reads on a file. - -Samba will not read ahead more data than the amount specified in the -"read size" option. It always reads ahead on 1k block boundaries. - - -MEMORY MAPPING --------------- - -Samba supports reading files via memory mapping them. One some -machines this can give a large boost to performance, on others it -makes not difference at all, and on some it may reduce performance. - -To enable you you have to recompile Samba with the -DUSE_MMAP option -on the FLAGS line of the Makefile. - -Note that memory mapping is only used on files opened read only, and -is not used by the "read raw" operation. Thus you may find memory -mapping is more effective if you disable "read raw" using "read raw = -no". - - -SLOW CLIENTS ------------- - -One person has reported that setting the protocol to COREPLUS rather -than LANMAN2 gave a dramatic speed improvement (from 10k/s to 150k/s). - -I suspect that his PC's (386sx16 based) were asking for more data than -they could chew. I suspect a similar speed could be had by setting -"read raw = no" and "max xmit = 2048", instead of changing the -protocol. Lowering the "read size" might also help. - - -SLOW LOGINS ------------ - -Slow logins are almost always due to the password checking time. Using -the lowest practical "password level" will improve things a lot. You -could also enable the "UFC crypt" option in the Makefile. - -CLIENT TUNING -------------- - -Often a speed problem can be traced to the client. The client (for -example Windows for Workgroups) can often be tuned for better TCP -performance. - -See your client docs for details. In particular, I have heard rumours -that the WfWg options TCPWINDOWSIZE and TCPSEGMENTSIZE can have a -large impact on performance. - -Also note that some people have found that setting DefaultRcvWindow in -the [MSTCP] section of the SYSTEM.INI file under WfWg to 3072 gives a -big improvement. I don't know why. - -My own experience wth DefaultRcvWindow is that I get much better -performance with a large value (16384 or larger). Other people have -reported that anything over 3072 slows things down enourmously. One -person even reported a speed drop of a factor of 30 when he went from -3072 to 8192. I don't know why. - -It probably depends a lot on your hardware, and the type of unix box -you have at the other end of the link. - - -MY RESULTS ----------- - -Some people want to see real numbers in a document like this, so here -they are. I have a 486sx33 client running WfWg 3.11 with the 3.11b -tcp/ip stack. It has a slow IDE drive and 20Mb of ram. It has a SMC -Elite-16 ISA bus ethernet card. The only WfWg tuning I've done is to -set DefaultRcvWindow in the [MSTCP] section of system.ini to 16384. My -server is a 486dx3-66 running Linux. It also has 20Mb of ram and a SMC -Elite-16 card.

There are two options "share level" and "user level". Which -of these two the client receives affects the way the client then tries -to authenticate itself. It does not directly affect (to any great -extent) the way the Samba server does security. I know this is -strange, but it fits in with the client/server approach of SMB. In SMB -everything is initiated and controlled by the client, and the server -can only tell the client what is available and whether an action is -allowed. - -I'll describe user level security first, as its simpler. In user level -security the client will send a "session setup" command directly after -the protocol negotiation. This contains a username and password. The -server can either accept or reject that username/password -combination. Note that at this stage the server has no idea what -share the client will eventually try to connect to, so it can't base -the "accept/reject" on anything other than: - -- the username/password -- the machine that the client is coming from - -If the server accepts the username/password then the client expects to -be able to mount any share (using a "tree connection") without -specifying a password. It expects that all access rights will be as -the username/password specified in the "session setup". - -It is also possible for a client to send multiple "session setup" -requests. When the server responds it gives the client a "uid" to use -as an authentication tag for that username/password. The client can -maintain multiple authentication contexts in this way (WinDD is an -example of an application that does this) - - -Ok, now for share level security. In share level security the client -authenticates itself separately for each share. It will send a -password along with each "tree connection" (share mount). It does not -explicitly send a username with this operation. The client is -expecting a password to be associated with each share, independent of -the user. This means that samba has to work out what username the -client probably wants to use. It is never explicitly sent the -username. Some commercial SMB servers such as NT actually associate -passwords directly with shares in share level security, but samba -always uses the unix authentication scheme where it is a -username/password that is authenticated, not a "share/password". - -Many clients send a "session setup" even if the server is in share -level security. They normally send a valid username but no -password. Samba records this username in a list of "possible -usernames". When the client then does a "tree connection" it also adds -to this list the name of the share they try to connect to (useful for -home directories) and any users listed in the "user =" smb.conf -line. The password is then checked in turn against these "possible -usernames". If a match is found then the client is authenticated as -that user. - -Finally "server level" security. In server level security the samba -server reports to the client that it is in user level security. The -client then does a "session setup" as described earlier. The samba -server takes the username/password that the client sends and attempts -to login to the "password server" by sending exactly the same -username/password that it got from the client. If that server is in -user level security and accepts the password then samba accepts the -clients connection. This allows the samba server to use another SMB -server as the "password server". - -You should also note that at the very start of all this, where the -server tells the client what security level it is in, it also tells -the client if it supports encryption. If it does then it supplies the -client with a random "cryptkey". The client will then send all -passwords in encrypted form. You have to compile samba with encryption -enabled to support this feature, and you have to maintain a separate -smbpasswd file with SMB style encrypted passwords. It is -cryptographically impossible to translate from unix style encryption -to SMB style encryption, although there are some fairly simple management -schemes by which the two could be kept in sync. -- cgit
