[Samba] File locks?
Hello, Recently, the following problem started happening with a particular samba server: If i have a file open for reading (say, a pdf in xpdf) and then try to write to it (say, through recompiling a latex document) it complains that it cannot open the file for writing. this seems like a file lock issue but I am unsure where it is happening. My previous usage should be perfectly safe since xpdf should only open for reading. This problem does not happen locally or when I connect to a different samba server (a windows machine). I can also ssh into the remote server, port xpdf , and my local process can write to the file. It is the samba connection that is making the lock. I am running Debian Unstable, using smbclient/smbfs 3.0.28a-2 to connect to a samba server (unix backend) on my university network. Server: Samba3.0.10-1.4E I mount the smb share in my fstab as follows: //myserver/jyoung/mnt/unismbfs credentials=credsfile,gid=jyoung,uid=jyoung,auto,rw I spoke with my system administrator and he said it may also be possible to get the server settings changed depending on what is required (and the implications). Thanks (This is a re-post, I apologize for any annoyance) Jim -- James Young, B.Sc.

Re: [Samba] File locks?
Thanks for the info. I am using the smbfs debian package, but mount tells me that type is cifs //nsh/jyoung on /mnt/uni type cifs (rw,mand) I have updated my fstab: //nsh/jyoung/mnt/unicifs credentials=/myfolder/credentials,gid=jyoung,uid=jyoung,auto,rw 0 0 and remounted, same problem.

Thanks, Jim On your local system. what's the outcome of 'modinfo cifs' ? Btw - recent debian/ubuntu packages ship versions of the smb/cifs userland helpers smbmount and smbumount, which are no longer mounting smbfs when specified. Instead they mount cifs vfs behind the scenes. Both are (usually) also called indirectly by the mount/umount programs. Technically spoken, 'mount -t smbfs ...' is (ususally) calling /sbin/mount.smbfs which formerly mounted smbfs - but now cifs vfs instead.

[Samba] Fwd: file locking issue
-- Forwarded message -- From: Jim Young [EMAIL PROTECTED] Date: 7 Apr 2008 09:11 Subject: file locking issue To: samba@lists.samba.org Hello, Until recently, I could work from my samba share and do the following: Edit a latex document, compile, view its pdf output in kpdf/xpdf. Leave the pdf viewer open, modify the document, recompile. then get the pdf viewer to reload (r key in xpdf). This no longer works, as the latex compile complains that it cannot open the output pdf file for writing. this seems like a file lock issue but I am unsure where it is happening. My previous usage should be perfectly safe since xpdf should only open for reading. I am not sure which upgrades correspond to this breaking as I was not using latex continuously. I am running Debian Unstable, using smbclient/smbfs 3.0.28a-1 to connect to a samba server (unix backend) on my university network. Server: Samba3.0.10-1.4E I mount the smb share in my fstab as follows: //myserver/jyoung/mnt/unismbfs credentials=credsfile,gid=jyoung,uid=jyoung,auto,rw I spoke with my system administrator and he said it may also be possible to get the server settings changed depending on what is required (and the implications).
