Other computers cannot ping my computer

Telnetd has nothing to do with the ability to ping the computer - you
should be able to ping you computer (if the firewall permits) even in
the absence of telnetd. The telnetd daemon is used to allow users to
access the computer from the network (more exactly - to give them access
to the shell on the computer). However, because telnetd does not encrypt
traffic (including users' passwords) its use is _strongly_ not
recommended. If you need to allow remote shell access for users, use SSH
(program 'ssh' on the client and 'sshd' on the server).
