2. How do I get the CIFS, SMB and NetBIOS protocols?

- -

- -

-

See the -meta FAQ on CIFS and SMB if you don't have any idea what these protocols are.

-

CIFS and SMB are implemented by the main Samba fileserving daemon, smbd. -.....

-

nmbd speaks a limited amount of CIFS (...) but is mostly concerned with -NetBIOS. NetBIOS is ....

-

RFC1001, RFC1002 ...

-

So, provided you have got Samba correctly installed and running you have -all three of these protocols. Some operating systems already come with -stacks for all or some of these, such as SCO Unix, OS/2 and ... In this -case you must ...

- -

2.1 What server operating systems are supported?

- -

- -

-

At the last count, Samba runs on about 40 operating systems! This -section looks at general questions about running Samba on the different -platforms. Issues specific to particular operating systems are dealt -with in elsewhere in this document.

-

Many of the ports have been done by people outside the Samba team keen -to get the advantages of Samba. The Samba team is currently trying to -bring as many of these ports as possible into the main source tree and -integrate the documentation. Samba is an integration tool, and so it has -been made as easy as possible to port. The platforms most widely used -and thus best tested are Linux and SunOS.

-

This migration has not been completed yet. This means that some -documentation is on web sites ...

-

There are two main families of Samba ports, Unix and other. The Unix -ports cover anything that remotely resembles Unix and includes some -extremely old products as well as best-sellers, tiny PCs to massive -multiprocessor machines supporting hundreds of thousands of users. Samba -has been run on more than 30 Unix and Unix-like operating systems.

- -

Running Samba on a Unix or Unix-like system

- -

-

-../UNIX-SMB.txt describes some of the issues that confront a -SMB implementation on unix, and how Samba copes with them. They may help -people who are looking at unix<->PC interoperability.

-

There is great variation between Unix implementations, especially those -not adhering to the Common Unix Specification agreed to in 1996. Things -that can be quite tricky are .....

-

There are also some considerable advantages conferred on Samba running -under Unix compared to, say, Windows NT or LAN Server. Unix has ...

2.6 Managing Samba Log files

- -

- -

- - -

2.7 I can't see the Samba server in any browse lists!

- -

- - -See -BROWSING.txt -for more information on browsing. Browsing.txt can also be found -in the docs directory of the Samba source.

-

If your GUI client does not permit you to select non-browsable -servers, you may need to do so on the command line. For example, under -Lan Manager you might connect to the above service as disk drive M: -thusly: -

-
-   net use M: \\mary\fred
-
-
- -The details of how to do this and the specific syntax varies from -client to client - check your client's documentation.

- - -

2.8 Some files that I KNOW are on the server doesn't show up when I view the files from my client!

- -

- - -See the next question.

- - -

2.9 Some files on the server show up with really wierd filenames when I view the files from my client!

- -

- - -If you check what files are not showing up, you will note that they -are files which contain upper case letters or which are otherwise not -DOS-compatible (ie, they are not legal DOS filenames for some reason).

-

The Samba server can be configured either to ignore such files -completely, or to present them to the client in "mangled" form. If you -are not seeing the files at all, the Samba server has most likely been -configured to ignore them. Consult the man page smb.conf(5) for -details of how to change this - the parameter you need to set is -"mangled names = yes".

- - -

2.10 My client reports "cannot locate specified computer" or similar

- -

- - -This indicates one of three things: You supplied an incorrect server -name, the underlying TCP/IP layer is not working correctly, or the -name you specified cannot be resolved.

-

After carefully checking that the name you typed is the name you -should have typed, try doing things like pinging a host or telnetting -to somewhere on your network to see if TCP/IP is functioning OK. If it -is, the problem is most likely name resolution.

-

If your client has a facility to do so, hardcode a mapping between the -hosts IP and the name you want to use. For example, with Man Manager -or Windows for Workgroups you would put a suitable entry in the file -LMHOSTS. If this works, the problem is in the communication between -your client and the netbios name server. If it does not work, then -there is something fundamental wrong with your naming and the solution -is beyond the scope of this document.

-

If you do not have any server on your subnet supplying netbios name -resolution, hardcoded mappings are your only option. If you DO have a -netbios name server running (such as the Samba suite's nmbd program), -the problem probably lies in the way it is set up. Refer to Section -Two of this FAQ for more ideas.

-

By the way, remember to REMOVE the hardcoded mapping before further -tests :-)

- - -

2.11 My client reports "cannot locate specified share name" or similar

- -

- - -This message indicates that your client CAN locate the specified -server, which is a good start, but that it cannot find a service of -the name you gave.

-

The first step is to check the exact name of the service you are -trying to connect to (consult your system administrator). Assuming it -exists and you specified it correctly (read your client's doco on how -to specify a service name correctly), read on:

-

-

-

- - -

2.12 My client reports "cannot find domain controller", "cannot log on to the network" or similar

- -

- - -Nothing is wrong - Samba does not implement the primary domain name -controller stuff for several reasons, including the fact that the -whole concept of a primary domain controller and "logging in to a -network" doesn't fit well with clients possibly running on multiuser -machines (such as users of smbclient under Unix). Having said that, -several developers are working hard on building it in to the next -major version of Samba. If you can contribute, send a message to -samba@samba.org !

-

Seeing this message should not affect your ability to mount redirected -disks and printers, which is really what all this is about.

-

For many clients (including Windows for Workgroups and Lan Manager), -setting the domain to STANDALONE at least gets rid of the message.

- - -

2.13 Printing doesn't work :-(

- -

- -

-

Make sure that the specified print command for the service you are -connecting to is correct and that it has a fully-qualified path (eg., -use "/usr/bin/lpr" rather than just "lpr", if you happen to be using -Unix).

-

Make sure that the spool directory specified for the service is -writable by the user connected to the service.

-

Make sure that the user specified in the service is permitted to use -the printer.

-

Check the debug log produced by smbd. Search for the printer name and -see if the log turns up any clues. Note that error messages to do with -a service ipc$ are meaningless - they relate to the way the client -attempts to retrieve status information when using the LANMAN1 -protocol.

-

If using WfWg then you need to set the default protocol to TCP/IP, not -Netbeui. This is a WfWg bug.

-

If using the Lanman1 protocol (the default) then try switching to -coreplus. Also not that print status error messages don't mean -printing won't work. The print status is received by a different -mechanism.

- - -

2.14 My programs install on the server OK, but refuse to work properly

- -

- - -There are numerous possible reasons for this, but one MAJOR -possibility is that your software uses locking. Make sure you are -using Samba 1.6.11 or later. It may also be possible to work around -the problem by setting "locking=no" in the Samba configuration file -for the service the software is installed on. This should be regarded -as a strictly temporary solution.

-

In earlier Samba versions there were some difficulties with the very -latest Microsoft products, particularly Excel 5 and Word for Windows -6. These should have all been solved. If not then please let Andrew -Tridgell know via email at -samba@samba.org.

- - -

2.15 My "server string" doesn't seem to be recognised

- -

- - -OR My client reports the default setting, eg. "Samba 1.9.15p4", instead -of what I have changed it to in the smb.conf file.

-

You need to use the -C option in nmbd. The "server string" affects -what smbd puts out and -C affects what nmbd puts out.

-

Current versions of Samba (1.9.16 +) have combined these options into -the "server string" field of smb.conf, -C for nmbd is now obsolete.

- - -

2.16 My client reports "This server is not configured to list shared resources"

- -

- - -Your guest account is probably invalid for some reason. Samba uses the -guest account for browsing in smbd. Check that your guest account is -valid.

-

See also 'guest account' in smb.conf man page.

- - -

2.17 Issues specific to Unix and Unix-like systems

- -

- -

- -

Printing doesn't work with my Unix Samba server

- -

- -

-

The user "nobody" often has problems with printing, even if it worked -with an earlier version of Samba. Try creating another guest user other -than "nobody".

- -

Log message "you appear to have a trapdoor uid system"

- -

- - -This can have several causes. It might be because you are using a uid -or gid of 65535 or -1. This is a VERY bad idea, and is a big security -hole. Check carefully in your /etc/passwd file and make sure that no -user has uid 65535 or -1. Especially check the "nobody" user, as many -broken systems are shipped with nobody setup with a uid of 65535.

-

It might also mean that your OS has a trapdoor uid/gid system :-)

-

This means that once a process changes effective uid from root to -another user it can't go back to root. Unfortunately Samba relies on -being able to change effective uid from root to non-root and back -again to implement its security policy. If your OS has a trapdoor uid -system this won't work, and several things in Samba may break. Less -things will break if you use user or server level security instead of -the default share level security, but you may still strike -problems.

-

The problems don't give rise to any security holes, so don't panic, -but it does mean some of Samba's capabilities will be unavailable. -In particular you will not be able to connect to the Samba server as -two different uids at once. This may happen if you try to print as a -"guest" while accessing a share as a normal user. It may also affect -your ability to list the available shares as this is normally done as -the guest user.

-

Complain to your OS vendor and ask them to fix their system.

-

Note: the reason why 65535 is a VERY bad choice of uid and gid is that -it casts to -1 as a uid, and the setreuid() system call ignores (with -no error) uid changes to -1. This means any daemon attempting to run -as uid 65535 will actually run as root. This is not good!
