Ping mean its check system is on network and telnet check
access of application.
If you can Ping but can't telnet it means a specific port
which that application use to communicate is blocked. Check
your firewall rule to fix it.

Answer / surender singh malik
Pinging a server just checks that Particular system is
present on the network.
Telnet or SSH are application to login the server from
remote and use the services provided by the server.
In TELNET DATA is not encrypted so it's easy to hack.
In SSH DATA is encrypted so it's safe.
