sudo lsof -nP -i4TCP:<port> I get the following (IPs are replaced by 'x' for security reasons):
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME openvpn 7670 _viscosity 5u IPv4 0x74709ea1cc0de131 0t0 TCP xxx.xxx.xxx.xxx:62357->xxx.xxx.xxx.xxxx:443 (ESTABLISHED)
My supposition is that this device is some type of memory location of a network interface, but I could not identify it.
My question is:
How to identify which network device (e.g. utun10 or so) is this device?
