We are investigating a rather large Samba implementation (15.000 users). Is there any built'in limit in Samba we should be aware of ? Max sessions, max shares... Thanx, cu, Frank. ----------------------------------------------- Runbox Mail Manager - www.runbox.com Free online email application

In particular, the total number of users might overwelm the flat-text file smbpasswd if you are using encrypted password. The Samba group is currently developing a TDB backend, which should increase performance. As Blue mentioned, memory is also an issue. There is the absolute _minimum_ requirement of approx 500-600KB per user. 3MB would not be uncommon. A suggestion would be to use shared memory where possible. Also have a great deal of swap space and maybe enable over-commit mode (which can be dangerous if you don't know what you are doing). There are also various tuning parameters which can be set in smb.conf.> Max sessions, max shares... >There might be max shares, but we are currently looking at sharing out home directories at present. == Incidentally -- though I should really post to samba-technical -- the TDB stuff in Samba-HEAD is broken again. As TDB is potentially very useful, I would like it fixed ASAP. Since this IS Free Software, I guess I should help out rather than moan about it. :) Can Jeremy or anyone else suggest what I can do. Testing and debugging at this stage isn't an option because Samba-HEAD doesn't even compile.

For the max shares, you have a "max connections = " on the [global] section of smb.conf that you can use. Mine is max connections = o <the default>, meaning, there's no limitation on connections to the share... hope i've helped... --- Spawn -- the Scourge of the Dammed Chris G Haravata Backend Team Leader IT Resources Asia Pacific College #3 Humabon Place, Magallanes Village, 1232 Makati City Tel 8529232 loc 402
