Telnet to Port

Telnet command is a good way to check if the connection between Client and License Server is good or allowed.

- At Command Prompt : telnet <IP Address of Targeted Server> <Port Number>

- Go to Command Prompt in Windows. Click <Start> / <Run> / Type “cmd” / Hit <Enter>

- Type ~ telnet 10.XX.XX.XX 2080 (10.XX.XX.XX is the specific License Server IP address and 2080 is the Port number)

 

- Hit <Enter>. Blank screen below signify a successful “telnet session”, means the connection is establish with the Port 2080.

 

- Should there be any form of blockage by security devices (eg. Firewall). You should see error messages.

 
 
- This signifies Server Port 2080 is inaccessible and you will expect problem in acquiring licenses (eg. Error -15).

- You should then advise IT Team to confirm if Firewall allow traffic to and from Port 2080.

[What can I do?]

I have Windows 7 64-bit and get this error:
'telnet' is not recognized as an internal or external command, operable program or batch file.

What can I do?

If you do not have TELNET you can go to "Programs and Features" in the Control Panel and select turn Windows features On or Off .. you will see TELNET listed as option.
