Agree. It's quite easy to telnet to a port to see if you get a response.
Do it a lot.
Are ifconfig, netstat, traceroute, et al really
insecure? (Maybe a case
could be made for traceroute) These types of changes to the core of
userland are epic dumb IMHO. Telnet is very useful for debugging, and
certainly dropping telnetd is a good thing - which everyone has done.
