Hi,

I don’t think this is not a good idea to allow telnet access nowaday.nobody is using telnet on linux box. Disable this service first

Also it is not a good idea to allow ssh access to everyone over the net
# Permitt SSH access to my ip and my network
/sbin/iptables -A INPUT -s 8.23.2.11 -p tcp –dport ssh -j ACCEPT
/sbin/iptables -A INPUT -s 4.3.8.0/24 -p tcp –dport ssh -j ACCEPT
