Nestat and Telnet

sumncguy · 09-13-2016, 09:09 AM

Why does telnet.socket show up as 1/systemd when executing

Quote:

netstat -tunalp | grep -i listen

Quote:

systemctl status telnet.socket

.. shows active (listening)

I would expect to see some kind of reference to telnet in the right most column of the netstat output.

Thanks for helping this guy trying to cert !

netstat queries, not listens?

AFAIK systemd works like (x)inetd here. It listens to telnet port until someone makes a connection, then it starts the real telnet daemon and passes the socket descriptor to its process.
