Would it help to add that to fstab? Where? Or should it go in the server's fstab? Or both?

But how do I get these byte-range locks between the Ubuntu clients? I have searched in Google and on Ubuntuforums without luck.

What is happening is that the Ubuntu clients are establishing a lock of deny_none, and the WinXP client is establishing deny_write. I have tried changing oplocks and kernel oplocks to yes, and all else to the defaults shown here, but there is no change in this behavior: http://www.physiol.ox.ac.uk/Computing/Online_Documentation/ using_samba/ch05_05.htmll What else should I try, please? :- Doug. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

[Samba] What affects file locking?
Hi-- We are in a production environment with one WinXP box and several linux boxes. We have discovered that the WinXP and linux boxes seem to respect each other's file locks, but that the linux boxes do not respect each other's locks. In other words, box 1 can have a file open, and at the same time box 2 can open it and edit and save the file. We have smb.conf set with level2 oplocks yes, kernel oplocks no, and oplocks no. When we first noticed the problem the last two were set to yes. The change has made the locks work sometimes, but not reliably. Are there other things besides the oplocks and the smb.conf file which can affect file locking? How would you trouble shoot this? Thanks! :- Doug. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
[Samba] Ubuntu 8.04 breaks samba file locking
Just upgraded Saturday from Ubuntu 7.10 to 8.04.01. File locking in Samba is now broken, meaning two different users can have the same file open at the same time and edit it. Server is RedHat 9.0 running Samba 2.2.7a-security-rollup-fix. This has been working well for us for several years. Have one WinXP box accessing the server using OOo 2.0. Have another couple of Win95 boxes. In addition, have one Ubunutu 6.06 box, and three other 8.04 boxes. It appears the XP and the 6.06 box lock files so the other cannot edit them while one has them open, but the 8.04 boxes, running OOo 2.4 can access and edit and save these files, thus causing havoc. The linux clients mount via cifs, such as this line from /etc/fstab: //samba1/vol22/sam/vol22 cifs rw,user,credentials=/[blanked],uid=doug,gid=data 0 0 This is a production environment. Could it be a mis-match between the version of samba on the server and the one on the clients? Can anybody suggest a solution or at least a trouble-shooting procedure?
