Hi everyone,
I have the exact same problem as this:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=772154
But the Samba version is different and much newer (Debian
Wheezy 2:4.1.17+dfsg-1~bpo70+1). B
asically many errors appear about non existing usershares. These fake
usershares are just the user name, but truncated of the last character.
process_usershare_file: stat of /var/lib/samba/usershares/netlogo
failed. No such file or directory
There are so many messages that the server performance drops
dramatically!
Our friend L.P.H. van Belle (who lurks here, I know) did an answer
to this bug report that I don't completely understand, though. So this
isn't a bug, alright. What is causing this? Are the client machines
trying to access these shares, or create it?
I don't understand either (or find in the documentation) how to disable
these usershares. Any help and explanation appreciated.

As apparently the problem still is the same with a 4.1 version, so I'm wondering if upgrading will help much... if that's a configuration problem that I don't really understand. -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac at intellique.com> | +33 1 78 94 84 02 ------------------------------------------------------------------------ -------------- next part -------------- A non-text attachment was scrubbed...

If it is, then you don't need the deprecated 'idmap gid' & 'idmap uid' Also you are telling Samba to use the wins server running on 127.0.0.1 and then telling Samba not to start its wins server, this is extremely odd.

No such file or directoryIt is not a bug per se, but I'd say it does not have the best default parameter value. Try adding the following parameter in your [global] section (the default value here is 100 on my Debian package) and restart smbd: [global] .... usershare max shares = 0 Cheers, Denis> There are so many messages that the server performance drops > dramatically! > > Our friend L.P.H. van Belle (who lurks here, I know) did an answer > to this bug report that I don't completely understand, though.

Did that back when I was in Novell selling SuSE Linux.

Can the users create shares remotely, through samba, using only the Windows explorer or the Mac Finder? -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac at intellique.com> | +33 1 78 94 84 02 ------------------------------------------------------------------------ -------------- next part -------------- A non-text attachment was scrubbed...
