+
+<P>
+<A NAME="unix_install"></A>
+</P>
+
+<H2><A NAME="ss2.1">2.1 I can't see the Samba server in any browse lists!</A></H2>
+
+<P>
+<A NAME="no_browse"></A>
+</P>
+<P>*** Until the FAQ can be updated, please check the file:
+*** ftp://samba.anu.edu.au/pub/samba/BROWSING.txt
+*** for more information on browsing.</P>
+<P>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:</P>
+<P>net use M: \\mary\fred</P>
+<P>The details of how to do this and the specific syntax varies from
+client to client - check your client's documentation.</P>
+
+
+<H2><A NAME="ss2.2">2.2 Some files that I KNOW are on the server doesn't show up when I</A>view the files from my client!</H2>
+
+<P>
+<A NAME="missing_files"></A>
+</P>
+
+
+<H2><A NAME="ss2.3">2.3 Some files on the server show up with really wierd filenames when</A>I view the files from my client!</H2>
+
+<P>
+<A NAME="strange_filenames"></A>
+</P>
+<P>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).</P>
+<P>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".</P>
+
+
+<H2><A NAME="ss2.4">2.4 My client reports "cannot locate specified computer" or similar</A></H2>
+
+<P>
+<A NAME="cant_see_server"></A>
+</P>
+<P>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.</P>
+<P>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.</P>
+<P>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.</P>
+<P>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.</P>
+<P>By the way, remember to REMOVE the hardcoded mapping before further
+tests :-) </P>
+
+
+<H2><A NAME="ss2.5">2.5 My client reports "cannot locate specified share name" or</A>similar</H2>
+
+<P>
+<A NAME="cant_see_share"></A>
+</P>
+<P>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.</P>
+<P>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:</P>
+<P>* Many clients cannot accept or use service names longer than
+eight
+characters.
+* Many clients cannot accept or use service names containing
+spaces.
+* Some servers (not Samba though) are case sensitive with service
+names.
+* Some clients force service names into upper case.</P>
+
+
+<H2><A NAME="ss2.6">2.6 My client reports "cannot find domain controller", "cannot log</A>on to the network" or similar </H2>
+
+<P>
+<A NAME="cant_see_net"></A>
+</P>
+<P>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-bugs!</P>
+<P>Seeing this message should not affect your ability to mount redirected
+disks and printers, which is really what all this is about.</P>
+<P>For many clients (including Windows for Workgroups and Lan Manager),
+setting the domain to STANDALONE at least gets rid of the message.</P>
+
+
+<H2><A NAME="ss2.7">2.7 Printing doesn't work :-(</A></H2>
+
+<P>
+<A NAME="no_printing"></A>
+</P>
+<P>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").</P>
+<P>Make sure that the spool directory specified for the service is
+writable by the user connected to the service. In particular 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".</P>
+<P>Make sure that the user specified in the service is permitted to use
+the printer.</P>
+<P>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.</P>
+<P>If using WfWg then you need to set the default protocol to TCP/IP, not
+Netbeui. This is a WfWg bug.</P>
+<P>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.</P>
+
+
+<H2><A NAME="ss2.8">2.8 My programs install on the server OK, but refuse to work properly</A></H2>
+
+<P>
+<A NAME="programs_wont_run"></A>
+</P>
+<P>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.</P>
+<P>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.</P>
+
+
+<H2><A NAME="ss2.9">2.9 My "server string" doesn't seem to be recognised</A></H2>
+
+<P>
+<A NAME="bad_server_string"></A>
+</P>
+<P>my client reports the default setting, eg. "Samba 1.9.15p4", instead
+of what I have changed it to in the smb.conf file.</P>
+<P>You need to use the -C option in nmbd. The "server string" affects
+what smbd puts out and -C affects what nmbd puts out. In a future
+version these will probably be combined and -C will be removed, but
+for now use -C</P>
+
+
+<H2><A NAME="ss2.10">2.10 My client reports "This server is not configured to list shared</A>resources" </H2>
+
+<P>
+<A NAME="cant_list_shares"></A>
+</P>
+<P>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.</P>
+<P>See also 'guest account' in smb.conf man page.</P>
+
+
+<H2><A NAME="ss2.11">2.11 Log message "you appear to have a trapdoor uid system" </A></H2>
+
+<P>
+<A NAME="trapdoor_uid"></A>
+</P>
+<P>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.</P>
+<P>It might also mean that your OS has a trapdoor uid/gid system :-)</P>
+<P>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.</P>
+<P>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.</P>
+<P>Complain to your OS vendor and ask them to fix their system.</P>
+<P>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!</P>
