Don't just tell us.  SHOW us.

unicorn:~$ sudo lsof -i :1812

If there's something using that port, lsof will show it:

STOP that!!

DO NOT use kill -9 unless it's ABSOLUTELY necessary!  Even if you think
it's absolutely necessary, consider rebooting instead.  You might have to
anyway, if some process is stuck on a hardware failure.

Sure sounds like something is using the port.  lsof should show it.  Or
ss, or netstat, if you use them correctly.

unicorn:~$ ss -ntl | grep :25
LISTEN 0      20           0.0.0.0:25         0.0.0.0:*

unicorn:~$ sudo ss -ntlp | grep :25
LISTEN 0      20           0.0.0.0:25         0.0.0.0:*    users:(("tcpserver",pid=657,fd=3))

(The -p option requires superuser privs.)

These results confirm that something *is* using the port.  Specifically,
it's "freeradius", which is apparently a user name, a program name, and
a service name.

So... it's not surprising that you get this result when you try to use
the port a second time.

What result were you expecting to see?

What are you trying to do?

Because it *is*.  The system is starting freeradius for you.  It's
running.  You've seen that it's running.

But now you want to start it *again*?  Why?  What's wrong with the one
that's currently running?

If you want to change the options that it uses, or something like that,
then you should configure the service so that it starts with the options
you require.
