http://en.tldp.org/HOWTO/SMB-HOWTO.html was last updated April 2000, long before Samba v3. V3 has broken much of what used to work between OS/2 and Linux, and, from what I hear, even between Linux and windoze. Does anyone know a modern substitute for this HOWTO that takes into account changes in Samba 3? Is anyone here working on an update to it? I'm willing to help test and troubleshoot to make that happen. I'm tired of being stuck on SuSE 8.2, the last distro I've been able to make coexist happily with OS/2. :-(

It's still working fine here.

Exactly what is working fine? Please share your config files.

An OS/2 workstation connected to a linux server via samba. Been working for more than a year with no problems or changes. First set up in Redhat 9 (gods know what samba version, 2.something, probably), thru SuSE 9.1, and now with SuSE 9.2 (Samba 3.0.7-4) The OS/2 side is warp 4.52, but I see no reason why eCS or Warp Server would be a problem here - warp peer has been stable since Warp 3. You might also see the back issues of OS/2 Magazine - I wrote several articles on how to network linux and OS/2 using samba and NFS. They both work fine.
