My client reports "cannot locate specified computer" or similar</H1 +><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 Lan 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.

My client reports "This server is not configured to list shared resources"</H1 +><P +>Your guest account is probably invalid for some reason. Samba uses the +guest account for browsing in smbd.

Log message "you appear to have a trapdoor uid system"</H1 +><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 +></DIV +><DIV +CLASS="SECT1" +><H1 +CLASS="SECT1" +><A +NAME="AEN132" +></A +>2.9. Why are my file's timestamps off by an hour, or by a few hours?</H1 +><P +>This is from Paul Eggert eggert@twinsun.com.</P +><P +>Most likely it's a problem with your time zone settings.</P +><P +>Internally, Samba maintains time in traditional Unix format, +namely, the number of seconds since 1970-01-01 00:00:00 Universal Time +(or ``GMT''), not counting leap seconds.</P +><P +>On the server side, Samba uses the Unix TZ variable to convert +internal timestamps to and from local time.
