Hey,

Looks like you disabled IPv6 support on your Linux server, e.g. by adding the kernel command line argument ipv6.disable=1 or via sysctl parameters. In that case you have two options:

  1. Re-enable IPv6 support.
  2. Change the Radius configuration not to listen on IPv6, but on IPv4 only. Do note that this requires changing the Univention templates the Radius configuration files are built from, with all the accompanying problems such as having to take extra manual care of modified templates during upgrades.

Kind regards,
mosu

Hi Mosu!
Really, you were right.
I had disabled ipv6 support
Thanks for the tip, this helped me sort it out.
