It also tells you what the likely cause of the problem -is if it fails any one of these steps. If it passes all these tests -then it is probably working fine. - -You should do ALL the tests, in the order shown. I have tried to -carefully choose them so later tests only use capabilities verified in -the earlier tests. - -If you send me an email saying "it doesn't work" and you have not -followed this test procedure then you should not be surprised if I -ignore your email. - - -ASSUMPTIONS ------------ - -In all of the tests I assume you have a Samba server called BIGSERVER -and a PC called ACLIENT both in workgroup TESTGROUP. I also assume the -PC is running windows for workgroups with a recent copy of the -microsoft tcp/ip stack. Alternatively, your PC may be running Windows -95 or Windows NT (Workstation or Server). - -The procedure is similar for other types of clients. - -I also assume you know the name of an available share in your -smb.conf. I will assume this share is called "tmp". You can add a -"tmp" share like by adding the following to smb.conf: - -[tmp] - comment = temporary files - path = /tmp - read only = yes - - -THESE TESTS ASSUME VERSION 2.0.6 OR LATER OF THE SAMBA SUITE. SOME -COMMANDS SHOWN DID NOT EXIST IN EARLIER VERSIONS - -Please pay attention to the error messages you receive. If any error message -reports that your server is being unfriendly you should first check that you -IP name resolution is correctly set up. eg: Make sure your /etc/resolv.conf -file points to name servers that really do exist. - -Also, if you do not have DNS server access for name resolution please check -that the settings for your smb.conf file results in "dns proxy = no". 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. Check what your guest account is using "testparm" and -temporarily remove any "hosts allow", "hosts deny", "valid users" or -"invalid users" lines. - -If you get a "connection refused" response then the smbd server may -not be running. If you installed it in inetd.conf then you probably edited -that file incorrectly. 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 want to test with -another account then add the -U option to the end of -the command line. eg: smbclient //bigserver/tmp -Ujohndoe - -Note: It is possible to specify the password along with the username -as follows: - smbclient //bigserver/tmp -Ujohndoe%secret - -Once you enter the password you should get the "smb>" prompt. 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. If it still fails after -that then look at the browsing options you have set in smb.conf. Make -sure you have "preferred master = yes" to ensure that an election is -held at startup. - -TEST 11: --------- - -From file manager try to browse the server. Your samba server should -appear in the browse list of your local workgroup (or the one you -specified in smb.conf). You should be able to double click on the name -of the server and get a list of shares. If you get a "invalid -password" error when you do then you are probably running WinNT and it -is refusing to browse a server that has no encrypted password -capability and is in user level security mode. In this case either set -"security = server" AND "password server = Windows_NT_Machine" in your -smb.conf file, or enable encrypted passwords AFTER compiling in support -for encrypted passwords (refer to the Makefile). - - -Still having troubles? ----------------------- - -Try the mailing list or newsgroup, or use the tcpdump-smb utility to -sniff the problem. The official samba mailing list can be reached at -samba@samba.org.
