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.
The startup log has no obvious errors I can see,
