Hi peterchu,

as root try :

1 - run /etc/init.d/iptables stop
to flush all iptables rules right now;

2 - delete /etc/sysconfig/iptables
to do not start new rules on next boot

It might not be the firewall.

service iptables stop

Then check the telnet configuration in /etc/xinetd.d

Change the disable=yes to disable=no

service xinetd restart

telnet will work.

May i suggest however you use ssh instead. Secure authentication is among its many advantages.
