determine if udp socket can be accessed via external client
- by JohnMerlino
I don't have access to company firewall server. but supposedly the port 1720 is open on my one ubuntu server. So I want to test it with netcat:
sudo nc -ul 1720
The port is listening on the machine ITSELF:
sudo netstat -tulpn | grep nc
udp 0 0 0.0.0.0:1720 0.0.0.0:* 29477/nc
The port is open…
