[NTLUG:Discuss] Strange Network Problem(s) on RedHat 7.1

[George E. Lass]

During the install I checked "no firewall" so I didn't think that would
be it, but to be sure I just tried the NFS copy and got the same I/O
error.

Thanks Anyway

George


P.S. The 2 PC's I'm working with are on the same 100mbps hub....
