samba - May 2000 - need help with SafeDelete

Hello Samba Gurus

I found a program that I think may be usefull if I can get it to work with 
Samba.  I am using RedHat 6.2 and I found a program included with the 
PowerTools called safedelete-1.3.  I read the man page for safedelete and 
it mentions creating a system alias "alias
rm='/usr/bin/safedelete'"  so
when you use rm to delete a file it will get backed up to a specified 
folder. This works fine, So now I am wondering what actually happens when a 
Samba client deletes a file? And is there any way to have the safedelete 
program handle the deleted file instead of letting Samba handle it.

Any Info would be greatly appreciated.
Thank You,

This is the same problem with most undelete utilities/hacks I have
seen.  They work fine for any program or shell that actually invokes
/bin/rm -- you just replace /bin/rm with your hack and you're good to
go.  Unfortunately, they do nothing for the unlink() and rmdir() system
calls that actually handle deletion.  Samba, just like Emacs, doesn't
go through the shell to delete things, and it doesn't call `rm'.  So
these programs won't work for them, won't work for most programs.  This 
is the same issue with those "file versioning" bolt-ons.

Some time ago I wrote a working prototype of a "recycle bin" for
Samba,
whereby a share-specific parameter "recycle bin =" specified where
deleted files should go.  It had several limitations and I never got
around to fixing them.  (I still hope to someday, as several people
expressed interest in such a facility.)  But it did demonstrate that
hacking things like this into the Samba source really isn't very hard.
Just grep for the remove(), unlink() and rmdir() system calls and do
your thing.

Happy hacking.
