unable to telnet to any servers
hello everyone. I've been poking around at hacking wargames sites and some of them allow you to telnet to their servers. But for some reason, I cant telnet to anything. I tried connecting to localhost and it says connection refused. I've tried connecting to hackerslab (drill.hackerslab.org, port 23.. it says name or service unknown) and pulltheplug.org (vortex.labs.pulltheplug.org, port 5842.. i get the message "trying 220.127.116.11" and never moves any further). At first I thought about contacting the wargames administrators but since I cant even connect to localhost (127.0.0.1) and also my own ip (18.104.22.168) I figure its me. I'm not that experienced with telnet so sorry if I'm acting "noobish" (God I hate that word).
