Ping works but not telnet in putty

pingtelnetunix

I am trying to ping one remote server. I am surprised that ping works but not telnet.

ping 174.25.366.25 --connection is successful.

where as

telnet 174.25.366.25 --connection timed out

I also want to check for connection on specific port

telnet 174.25.366.25 8090  ---connection timed out

Why is that difference and what does it convey

Well from what you say you got a port problem

  1. your ISP might block the port
  2. or you didn't forward the port
