Hi all, I searched the archives for a solution to this issue but didn't find any thing. I have an office with a mix of PCs running ME and XP that use Samba 2.2.7 under RH Linux 7.3 as an archive for mortgage information. When documents are moved to the Samba share, the file creation timestamp on the Linux box reflects the time the files were created on the PCs. What I need is for the creation timestamp to be when it was created on the Linux box by the copy or move. We have some scripts that execute every 20 minutes that use find to locate new files added within that time frame. Files are falling through the cracks because the script sees the original PC creation time and not the Linux creation time. Any insight on how to remedy this will be great appreciated!

The creation date on a file on a Samba share is really the mod time of the file. Unix file systems only store 3 times (atime, ctime, & mtime). cheers, jerry ---------------------------------------------------------------------- Hewlett-Packard ------------------------- http://www.hp.com SAMBA Team ---------------------- http://www.samba.org GnuPG Key ---- http://www.plainjoe.org/gpg_public.asc ISBN 0-672-32269-2 "SAMS Teach Yourself Samba in 24 Hours" 2ed "You can never go home again, Oatman, but I guess you can shop there." --John Cusack - "Grosse Point Blank" (1997) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: For info see http://quantumlab.net/pine_privacy_guard/ iD8DBQE+KXMDIR7qMdg1EfYRAsUlAJ92SvnrUrgJ+azEQ5k35017kcMOZQCgy0ZW /dlNHmQjJL+29/n+uXKAK3w=nMks -----END PGP SIGNATURE-----
Just free associating here. The parameter dos filetimes may relate to your situation. If samba does not have an easy way of doing this, you might get creative. You might use force create mode to change the permissions of the file when it is transferred (created?) to the samba share. For example, you might make any new file transferred up to be unreadable by anyone but the owner. Or, you could use force user to make it owned by some bogus owner like newfile (which may have to exist). Then, every minute, on the server run a script which touch'es any file with those ownership or permissions characteristics. This script could also change the file permission/ownership back to what they should be.

Here is what man smb.conf has to say:
dos filetimes (S)
Under DOS and Windows, if a user can write to a
file they can change the timestamp on it. Under
POSIX semantics, only the owner of the file or root
may change the timestamp. By default, Samba runs
with POSIX semantics and refuses to change the
timestamp on a file if the user smbd is acting on
behalf of is not the file owner. Setting this
option to true allows DOS semantics and smbd will
change the file timestamp as DOS requires.
Default: dos filetimes = no
Now, it may be that the user smbd is running under doesn't own the file.
But, it may be that dos filetimes won't, at least by themselves, solve
this problem.
See my other post about a brute force workaround.

I just ran for i in `find . -maxdepth 1 -perm 000` do touch $i chmod 777 $i done on a directory with 1700 files. It found, touch'ed, and chmod'ed 17 files with 000 permissions in less than one second on an AMD 267 mh. find is an executable binary, not some slow perl or bash script. So, it may not be too great a burden on your cpu to run this find command every minute. Give the speed of the find command, is there a reason why you wouldn't just send the email message every minute, instead of waiting 5 minutes between messages. Or, run the find command every five minutes, then the email command. The inability of samba to automatically change the access times of uploaded files sounds like a feature, not a bug!
