As long as there's not a physical firewall between you and the other pc's you can see if the linux firewall (netfilter) is running with the iptables command (as root)

$ iptables -L

will show you any rules that are setup.

You can turn netfilter/iptables off with

$ service iptables stop

To make sure it doesn't start next reboot

$ chkconfig iptables off

To install telnetd with up2date run

$ up2date -i telnet-server

Good luck,
Nick .
