telnet disconnects/firewall help?

[DJ]

I just tried uncommenting the port 23 line so it looks like this..
> ipchains -A eth0-in -p tcp -s 0/0 23 -y -j ACCEPT
> #ipchains -A eth0-in -p tcp -s 0/0 21 -y -j ACCEPT
but I am still unable to connect or even get a login prompt..
I still get a connection to host lost..? hmm so it must be making a connection
and losing it right?
do you know of anything else to check? dependancies?
I apreciate your help!
