I've had a proxy configuration setup to forward copies of accounting updates to two other radius servers for several years. Recently, I added a third (which one of the original two will be moving to), however it's not working: while the original ones get the expected start/stop/interim-updates, the new one only gets "accounting-on" packets while the updates just pile up in the detail file. That particular server ignores anything but start, stop and interim-update records (it's a vendor I have no control over). In monitoring what gets sent out, after restarting the radius server, I do not see Accounting-On getting sent to the original ones, so I don't understand why it's happening with the new one. The configurations are identical except for the detail file name and the ip address (I only included the configs for the two related proxy targets for simplicity): mods: detail detail-calix { filename = ${radacctdir}/detail-calix escape_filenames = no permissions = 0600 header = "%t" } detail detail-newcalix { filename = ${radacctdir}/detail-newcalix escape_filenames = no permissions = 0600 header = "%t" } replicate { Replicate-To-Realm = calix Replicate-To-Realm = newcalix } sites: server relay-calix { listen { type = detail filename = ${radacctdir}/detail-calix load_factor = 10 } preacct { update control { Proxy-To-Realm := "calix" } } accounting { ok } pre-proxy { } post-proxy { } } server relay-newcalix { listen { type = detail filename = ${radacctdir}/detail-newcalix load_factor = 10 } preacct { update control { Proxy-To-Realm := "newcalix" } } accounting { ok } pre-proxy { } post-proxy { } } proxy.conf: proxy server { default_fallback = no } # /usr/bin/radrelay -S /etc/raddb/secret.calix -r 199.71.142.73 detail-calix home_server calix { type = acct ipaddr = 199.71.142.73 port = 1813 secret = xxx status_check = none check_interval = 30 check_timeout = 4 num_answers_to_alive = 3 max_outstanding = 65536 } home_server_pool calix_pool { type = fail-over home_server = calix } realm calix { acct_pool = calix_pool } # /usr/bin/radrelay -S /etc/raddb/secret.newcalix -r 199.71.142.73 detail-newcalix home_server newcalix { type = acct ipaddr = 199.71.143.36 port = 1813 secret = xxx status_check = none check_interval = 30 check_timeout = 4 num_answers_to_alive = 3 max_outstanding = 65536 } home_server_pool newcalix_pool { type = fail-over home_server = newcalix } realm newcalix { acct_pool = newcalix_pool }
