Troubleshooting with telnet

Using Telnet to Troubleshoot Connection Issues

Background

Sometimes when a vendor is unable to connect to an interface it is a networking issue between the client and vendor. A great way to troubleshoot this is by using telnet.

Process

• On the ConnectR server open the Command Prompt, and type in: telnet localhost "port number"

  

• Next on the vendors interface server telnet to the IP address and port

  

• Once you click enter the screen should go blank; this means you're connected.
• ConnectR status should change from Waiting to Connected

Explanation

If it works from the ConnectR machine and not the vendor, then it's a networking or firewall issue. If it doesn't work on ConnectR, then most likely the source interface is turned off or misconfigured.
