If you can ping a server, but can't telnet or ssh to it,
what could be the problem?

Answer Posted / sanoopnarayan

As far as Im concerned there are three chances...

1. Services (SSh, telnet) may be disabled.
2. Service ports (ssh:22, telnet:23) may be disabled.
3. System may be in single user mode(init 0. init 1, init S) .
