Felix, if you MUST reply via email, could you make it with a VALID
reply-to email address so I can answer you?

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.
