I shutdown that file server every night and boot everything fresh in the morning. I still rather suspect Kubuntu for one because Kubuntu stinks, especially regarding NFS and then because four other OS/distros mount and access the same mount just fine. A friend of mine pointed out he heard of a strange bug where perms go fubar when the user is more than 16 groups. Don't have the time to trim down the groups right now, ever head of such a thing? > The bottom line is that Linux, although its NFS client implementation is > fairly sound (albeit wack beyond imaginable sometimes), makes a horrible > NFS server.

NFS did the job way better than Samba here, in terms of special chars, performance, reliability. First time in... umm... 3 years I think I really run into trouble.
