Description

When we have a RADIUS server with a configured accounting port instead of 1813 or not configured at all, CLI always be freezing. pam_radius get accounting port from /etc/services.
Will be good to have the possibility to disable pam radius accounting to prevent this issue.

Maybe disable sent "accounting messages" by default and enable it as a configuration option explicitly?

Tested in VyOS 1.4.0-rc1 , VyOS 1.3.5 and VyOS 1.5-rolling-202401030023
The configuration
VyOS 1.4.0-rc1:

set interfaces ethernet eth0 address '10.55.8.241/24'
set service ssh
set system login radius server 10.55.8.21 key 'testing123'
set system login radius server 10.55.8.21 port '1812'
set system login radius server 10.55.8.21 timeout '5'
set system login radius source-address '10.55.8.241'

VyOS 1.3.5:

set interfaces ethernet eth0 address '10.55.8.242/24'
set service ssh
set system login radius server 10.55.8.21 key 'testing123'
set system login radius server 10.55.8.21 port '1812'
set system login radius server 10.55.8.21 timeout '5'
set system login radius source-address '10.55.8.242'

VyOS 1.5-rolling-202401030023:

set interfaces ethernet eth0 address '10.55.8.243/24'
set service ssh
set system login radius server 10.55.8.21 key 'testing123'
set system login radius server 10.55.8.21 port '1812'
set system login radius server 10.55.8.21 timeout '5'
set system login radius source-address '10.55.8.243'

In RADIUS server side server does not listen to port 1813 only 1812
