->This file contains a list of tests you can perform to validate your
-Samba server. 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.</P
-><P
->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.</P
-><P
->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.</P

->Assumptions</A
-></H1
-><P
->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).</P
-><P
->The procedure is similar for other types of clients.</P
-><P
->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:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
->&#13;[tmp]
- comment = temporary files
- path = /tmp
- read only = yes&#13;</PRE
-></P
-><P
->THESE TESTS ASSUME VERSION 2.0.6 OR LATER OF THE SAMBA SUITE. SOME
-COMMANDS SHOWN DID NOT EXIST IN EARLIER VERSIONS</P
-><P
->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.</P
-><P
->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"</P

->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.</P
-><P
->Note: Your smb.conf file may be located in: <TT
-CLASS="FILENAME"
->/etc</TT
->
- Or in: <TT
-CLASS="FILENAME"
->/usr/local/samba/lib</TT

->Test 2</A

-><P
->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. </P
-><P
->Note that you will need to start a "dos prompt" window on the PC to
-run ping.</P
-><P
->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. </P
-><P
->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.)</P

->Test 3</A
-></H2
-><P
->Run the command "smbclient -L BIGSERVER" on the unix box. You
-should get a list of available shares back. </P
-><P
->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.</P
-><P
->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".</P
-><P
->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.</P
-><P
->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:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
-> hosts deny = ALL
- hosts allow = xxx.xxx.xxx.xxx/yy
- bind interfaces only = Yes</PRE
-></P
-><P
->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:</P
-><P
-><PRE
-CLASS="PROGRAMLISTING"
-> hosts deny = ALL
- hosts allow = xxx.xxx.xxx.xxx/yy 127.</PRE
-></P
-><P
->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).</P
-><P
->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!</P
-><P
->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.</P

-><P
->Run the command "nmblookup -B BIGSERVER __SAMBA__". You should get the
-IP address of your Samba server back.</P
-><P
->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.</P
-><P
->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.</P

-><P
->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. </P

-><P
->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.</P
-><P
->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. </P
-><P
->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.</P
-><P
->This test will probably fail if your subnet mask and broadcast address are
-not correct. (Refer to TEST 3 notes above).</P

-><P
->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.</P
-><P
->If you get "specified computer is not receiving requests" or similar
-it probably means that the host is not contactable via tcp services.
