I am having problems with getting Fedora 3 to Display xwindows across
the network.
I have variations of RedHat system from 7.3 to Enterprise 3 and
Fedora 3. I use ipchains or iptables along with /etc/hosts.allow to
control access to the systems.
The Fedora 3 systems are allowing ssh/sftp into them from specific
addresses only and allowing nfs mounts, but they are not allowing me
to ship a DISPLAY across the network.
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on numbers.geo.brown.edu (128.148.124.52):
(The 1594 ports scanned but not shown below are in state: closed)
