Chris Green [EMAIL PROTECTED] writes: I'm having a problem where I can gain the lock but the process is still writing to the file. OK, I realized that putting python in might have scared away anyone that knew C enough to help me out on my problem so I wrote a tiny util to look at the fcntl based locks. http://cmg.dok.org/code/lockview.c As I copy the file from NT - Linux 2.4, There are no locks set on the file. However, if I turn strict locking on, posix.c/is_posix_locked will return true as soon as I gain the lock and abort the copy. If just plain locking is on, the file will be deleted as soon as the copy is complete if another process has gained a write lock. Does anyone else use samba as a drop box for a unix process? Is there anyway to make a file be locked upon creation with the copy command?

My problem isn't picking up the file when it's copied in, but picking it up when it's complete. Looking at the imon ( and linux fcntl(2) ), there doesn't seem to be a way to say let me know I'm the only person using this file short of mandatory locking. The work around for the users in my case is to copy the file, and then rename but I'd really like it to be a one step operation.

[Samba] locks cooperating with a server side process
Good day folks, I'm using Samba 2.2.8a [1] on Slackware 9.1 with 2000/XP clients. I'm attempting to have a process by which a user drags a file using Windows Explorer into a share. On the server side, I have a unix process that polls the directory for new files and then reads them and deletes them. I'm having a problem where I can gain the lock but the process is still writing to the file. Python code: import fcntl # open file in rw so I gain exclusive lock f = open(cygwin.tar,r+) # if this doesn't raise an IOError, the lock is acquired fcntl.lockf(f,fcntl.LOCK_EX|fcntl.LOCK_NB) which maps into a fcntl exclusive lock with 0 as the start, end, and whence arguments in the flock structure. In smb.conf, locking = yes had no effect on my process. The next thing I tried was strict locking = yes. This had the effect that as soon as my code performs the lock, a windows dialog appears: ``Cannot copy cygwin: The process cannot access the file because another process has locked a portion of the file'' This leads me to suspect that either Windows Explorer or samba doesn't gain a lock on the file on creation. Is there a way to tell samba to set that lock?

[Samba] WinXP cannot connect to PDC
I am running RH8 and samba 2.2.7 and have been working to get the PDC running for about 4 days. I initially got it working but then transfered my local xp profile to it and it has not worked since. I receive the message that the domain controller is unavailable. I am at my wits end and frustrated that I do not understand the log files. Any help would be greatly appreciated.
