Subject: cifs mounted home directory problems - msg#00038List: linux.file-systems.cifsIs there a workaround or fix for the ':' problem? It still seems to be a problem, even in linux kernel 2.6.10 /Samba 3.0.10. ...or I might very well have overlooked some inanely obvious setting that solves this darn thing. I'm trying to set up a Samba server on a Linux (2.6.10) box which will be serving home dirs for Linux users. I don't want to use NFS, so I hoped smb or cifs would do the trick. I'm using pam_mount to set this up - and it works, as far as mounting goes. The problem is Evolution, KDE and other apps that use filenames with the colon character (':') in them. Doing a stat on one of these files tells me quite rightly that it is a regular file and all looks well up to that point, but if I try to cat one of these files I get an error message saying "Not a directory". Well of course it's not a directory! stat just told me it's a regular file... grrrr! At this point frustration got the best of me, hence this email. :-) Any suggestions are welcome...

Is SMB signing required (typically is required by the server, when a Windows2003 server is a domain controller or a member of a domain, rather than standalone server)?

Everything went well until our sysadmins decided to give our machines new IP addresses (because we switched from internet provider). >From then on, I get a “resource temporarily unavailable” error when I try to mount the third share. If I try mounting again, it works fine. First, I thought there was a problem with the third share, but reversing the mount order results in the same strange behaviour that was not present before the IP move. What is worse, after a few hours, these shares seem to get locked (an “ls” command does not return, “df” does not return, but the rest of the machine still works fine). Hereunder, you can find first the mount commands I use, indicating the mount errors. Next is a part of /var/log/syslog when these shares got stuck. Do you have any idea what is causing these errors or how I can prevent them.
