You do know that FC2 hasn't been supported at fedoralegacy.org since
last July, right? You may want to consider updating that. FC6 has been
available for two months now.

box I was using for a general server (MySQL, Apache, NFS).

Sounds as if you are running X on a server. Not the best idea.

This issue has been resolved and all is back to normal with the previous
15" monitor setting. Item #2 is still unresolved for now.

2 - I would like to be able to telnet to perform some automated data
updates between my linux boxes via perl. ssh is not supported very
cleanly through perllibs, so Net::Telnet is the only reasonable
solution.

The reason telnet is deprecated in favor of SSH is that everything is
done as clear text over the network - usernames, passwords, commands,
and so on. If you feel that someone running a packet sniffer on your
local network is not a problem, then telnet is adequate.

The problem I have is that even though I have xinetd and telnet
loaded, I am unable to connect between the two linux boxes via
telent. I keep getting this message:
telnet gentoo
Trying 192.168.2.194...
telnet: connect to address 192.168.2.194: Connection refused

They may be loaded (I assume that means "installed"), but are they
_configured_ to allow such connections. Is 'xinetd' running? (Look
at the output of 'ps auxw' and see if the process is there.) Is the
telnet service enabled? (Look at the output of 'netstat -atnp' - is
something listening to port 23/tcp? Look at the contents of the
/etc/xinetd.d/telnet file - is the line 'disable =' set to 'no'?)
Is there a 'tcp_wrappers' problem? ('man 5 hosts_access' then look at
the contents of /etc/hosts.allow and /etc/hosts.deny.) Is there a
firewall issue? (/sbin/iptables -L)
