Failed binding to auth address 127.0.0.1 port 18120 bound to server inner-tunnel: Address already in use

Question

I have configure freeradius following this tutorial.

But when I run a command

"freeradius -X" 

I got the following error radiusd:

Opening IP addresses and Ports #### listen { type = "auth" ipaddr =

127.0.0.1 port = 18120 Failed binding to auth address 127.0.0.1 port 18120 bound to server inner-tunnel: Address already in use /etc/freeradius/3.0/sites- enabled/inner-tunnel[33]: Error binding to port for 127.0.0.1 port 18120

Solution

The process is already running.To fix this run

netstat -tulp | grep "18120" 

check the PID of process, then run kill -9 (PID that you got) rerun freeradius -X

You probably already had a process running?

Reboot will fix almost anything, but it's taking a hammer to crack a nut.
