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). Alexey Fadyushin.
