Actions take

  • reading online about the error at the end says that port 1812 is being used elsewhere therefore I need to ensure that it’s not use so freeradius can bind to it. but I can’t seem to find what service is holding on that port that is not freeradius itself

freeradiu 5683 freerad   14u  IPv6 2234891      0t0  UDP *:radius

I tried to stop the service and restart it but same debug from freeradius

Any ideas?


#2

Hey,

How did you try to stop the running service? Use this:

# Stop the service:
systemctl stop freeradius.service
# Make sure systemd thinks it isn't running (see line "Active:"):
systemctl status freeradius.service
# Verify it isn't still running from outside of systemd's managed scope:
lsof -Pni:1812

If it is still running in step 3, simply send all mentioned PIDs the command to terminate: kill <PID1> <PID2>… If they persist, use kill -9 <PID1>…

m.

Hi Moritz

Thank you for your reply
to answer your questions I was using
sudo freeradius stop,
so I gave it a try with systemclt as you suggested but eventhough I see the service was fully stop and there was no process latched to port 1812, once I restart freeradius and test it with -X I’m still getting the same error binding message: here’s what I did:

#4

Hey,

freeradius stop is definitely not the correct way to stop a service.

if systemctl status… says it’s stopped, but there’s still a process running, then it’s one not under control of systemd. Kill that process manually like I’ve explained in my first.

m.


#5

Hi Moritz

Again, thank you for getting back to me and for your patience.

indeed, I stopped the service as you indicated and doing sudo lsof -Pni:1812 shows no service using that port.
when I restart the service, also with systemctl as you indicated, I check for processes working with port 1812, the only service on that port appears to be freeradius

Administrator@optiplexmint:~$ sudo netstat -tulpn | grep "1812"
udp        0      0 127.0.0.1:18120         0.0.0.0:*                           30985/freeradius    
udp        0      0 0.0.0.0:1812            0.0.0.0:*                           30985/freeradius    
udp6       0      0 :::1812                 :::*                                30985/freeradius    
Administrator@optiplexmint:~$ sudo lsof -Pni:1812
COMMAND     PID    USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
freeradiu 30985 freerad   12u  IPv4 5649699      0t0  UDP *:1812 
freeradiu 30985 freerad   14u  IPv6 5649701      0t0  UDP *:1812 

yet, for some reason freeradius debug mode still shows me the binding error.

Actions taken

  1. I’ve tried looking for any other processes latched on 1812 with
    sudo lsof -Pni:1812
    netstat -tulpn | grep :80
    fuser 1812/udp
    but again the only process that comes up is freeradius’ if started or none if stopped.

  2. I un-installed the radius module from the gui console, checked for processes on 1812 and nothing. Then I proceeded to install again the radius module, configure again clients.conf and restarted the service, but again when checking on debug mode expecting to find the message that says that freeradius is waiting on request… I then again get the same error message reported in this post.

what am I missing?

thank you.


#6

You cannot have freeradius running when trying to start it in debugging mode. In debugging mode, it will start a new server and act just like a regular server, just with a lot more logging. It doesn’t try to switch an already running instance into debug mode, no, it tries to start a new one.

You have to stop all running instances of freeradius. Do not try to start it again with systemctl (and I never told you to do that, BTW). Then, and only then, run freeradius in debug mode.


#7

That’s what I was missing/misunderstanding… thank you so much Moritz for your clarification and patience. newbie here.

Cheers
