Hi. FreeRadius 2.1.6 running in Redhat Linux AS5.3 We are upgrading from ancient radius servers to current, and discovered the radrelay program no longer exists. Despite my best efforts, I have failed to configure relaying correctly. I think I am including below the required changes. I hope someone that has done this successfully can easily see where I went wrong. (Thanks in advance!) We have two (2) radius servers (Redhat Linux AS5), radius-a and radius-b and wish to replicate accounting info between them. (Previously radius-1 ran radrelay to radius-2 and radius-2 ran radrelay to radius-1 -- just to be clear) For my testing, I am attempting to get radius-a to replicate to radius-b (Get things working in 1 direction first.) I have created a symbolic link in /usr/local/etc/raddb/sites-enabled/ to /usr/local/etc/raddb/sites-available/copy-acct-to-home-server I have ADDED the following to (and REMOVED NOTHING FROM) the proxy.conf file, home_server radius-b { type = acct ipaddr = 192.168.1.226 port = 1813 secret = booboo require_message_authenticator = no response_window = 20 zombie_period = 40 revive_interval = 120 status_check = status-server check_interval = 30 num_answers_to_alive = 3 coa { # Initial retransmit interval: 1..5 irt = 2 # Maximum Retransmit Timeout: 1..30 (0 == no maximum) mrt = 16 # Maximum Retransmit Count: 1..20 (0 == retransmit forever) mrc = 5 # Maximum Retransmit Duration: 5..60 mrd = 30 } } home_server_pool my_acct_relay { type = fail-over home_server = radius-b } realm relay_realm { acct_pool = my_acct_relay } ~~~~~~~ I have modified the file /usr/local/etc/raddb/sites-enabled/copy-to-home-server as follows, server copy-acct-to-home-server { listen { type = detail #CEC filename = ${radacctdir}/detail filename = ${radacctdir}/%{Client-IP-Address}/detail-%Y%m%d load_factor = 10 } preacct { #CEC Added this from web searches... update control { Proxy-To-Realm := relay_realm } preprocess suffix files } ~~~~~~~ Accounting packets are being sent from 192.168.1.101 to radius-a and are logged. No IP traffic has been detected from from radius-a to radius-b. The detail file I expect is being updated. No log files of the form, ${radacctdir}/%{Client-IP-Address}/pre-proxy-detail-%Y%m%d and ${radacctdir}/%{Client-IP-Address}/post-proxy-detail-%Y%m%d have been created, although I thought they should have been.
