There's currently no option to set the syslog facility
specifically in rlm_linelog. It will always log to the same
syslog_facility set in radiusd.conf.

If you want it different to the main server syslog, try the patch
below (majority of which taken from mainconfig.c), or pull from
https://github.com/mcnewton/freeradius-server/commit/089c108c472a6a9d2a21ae86b41343b06274f95d

In modules/linelog, set:

linelog {
  filename = syslog
  syslog_facility = local0
  ...
}

Alternatively, use syslog-ng (for example) and filter based on the
content of the log string.

Cheers,

Matthew
