In Windows, you can test connection to TCP port from the command line using PowerShell and in this note i will show how to do this. The most common tool for this is telnet, but it may not be installed or you may want to be able to copy the output to paste it into a ticket or to send it someone, that is not always possible with telnet.Īlso the telnet command is not very handy if you need to check connectivity to multiple hosts/ports, but you can do this easily with a PowerShell. During troubleshooting of different issues it is often required to check if some TCP port on a remote host is opened and ensure that it is not blocked by a firewall. Next, check NI License Manager (NILM) and Volume License Manager (VLM) configuration and connectivity. The ports used by NI License Manager to communicate with Volume License Manager on the Volume License Server should be open and should allow for interaction between NI License Manager and Volume License Manager. It’s recommended to work with an IT team (if applicable) to resolve this issue. IMPORTANT NOTE: By default root is not able to login via telnet. To know more about telnet, read this Wikipedia link. By default telnet server listens on port number 23/tcp. This means that something between the client and the volume license server is blocking the TCP communication. Whereas telnet do not communicates in encrypted way.
