How to Telnet

Introduction

Using the telnet command you can test if a port is open.

Solution

You can check if a port is open in your network by issuing the telnet command. 

 

telnet [domainname or ip] [port]

where

  • [domainname or ip] is the domain name or IP address of the server to which you are trying to connect
  • [port] is the port number where the server is listening

If the port is open, you will see a blank screen. This will mean that connection is successful.

For example

telnet relay.appriver.com 2525

 

In Windows Vista and Windows 7 you may need to enable telnet first:

  • Go to Start -> Control Panel -> Programs;
  • Under Programs and features, click Turn Windows features on or off;
  • Tick off both Telnet Client and Telnet Server;
  • Click OK.
