That's good. For this purpose, you can actually cut out quite a
lot - but make sure you've got your config in version control
(e.g. git) before you start so that you can easily backtrack if
things go wrong.

copy-acct-to-home-server reads a detail file and pushes the
"packets" into a virtual server for processing. So you need to
write to a detail file for it to read. From your debug output it
looks like you're using the standard configuration for 'detail',
which won't be where copy-acct-to-home-server expects to read it

Try something like


detail relay_detail {
  detailfile = ${radacctdir}/relay-detail


accounting {

That should get all accounting packets buffered to
${radacctdir}/relay-detail. Then you need to read them and forward
them on, so -


server copy-acct-to-home-server {
  listen {
    type = detail
    filename =  ${radacctdir}/relay-detail
  preacct {
    update control {
      Proxy-To-Realm := 'home_realm'
  accounting {

Then make sure your proxy.conf is configured with realm home_realm


realm home_realm {

This should all write accounting packets to the local detail file,
then read them and send them over to the home server. If the home
server is down, they will buffer up on this system until the home
server comes back again. That should mean you don't drop any logs.

Run radiusd -X and watch the output. You should see packets coming
in (like your original post), but you should also see the detail
reader wake up every second or so and check for packets to relay.
If you're not seeing that, then you haven't enabled
copy-acct-to-home-server correctly. You should then see that pick
up packets and process them.
