linux - Is there a way to check if a certain port is open on server? -


just you'd ping ip of server check if up, can check if, on running server, port active/open?

this comes head,but can more specific in ping statement?

 `ping 127.0.0.1:7004`

i know command not allowed, there way check in linux , windows?

that depends upon access system (client or server), can use either of 2 options,

  1. server side can use netstat -an check ports listening
  2. from outside use telnet host port, if not working on linux machines try telnet host:port.
