telnet on udp ports

[suthomas1]

Hi ,

To test if any port is active or opened by firewall or not, we can use telnet if port is tcp.

How to check if the port to be verified is udp one.will telnet work?

Thanks!

No, Telnet only makes TCP connections.

You can try using a port scanner or something to scan for open connections.
