Hi,

I am running 2.1.1-7.10.1 freeradius server on SLES.

its the end of 2014 - upgrade

Basic log is being written to the default log location (/var/log/radius/raidus.log), but I noticed sometimes, some NAS client IP is not logged. I am sure the this info is available in the debug mode. Afterall the clients.conf is checking the ip come in.

clients.conf looks at the raw packet detailsm not the RADIUS datagram. its very likely that NAS-IP-Address isnt in those packets - thus its not being logged. or the NAS-IP-Address is something different/wrong - eg hostname, MAC address or IPv6 address or something b0rked.

for example, a normal record would look like this: <Date> : Auth: Login OK: [james13] (from client able322 port 0 cli 10.22.31.51) but an incorrect record would look like this <Date> : Auth: Login OK: [james13] (from client able322 port 0)

Has anyone seen this kind of problem, or can someone advice me on how to alter to log manually to record this piece of info.

this looks like a feature of the NAS - some kind of caching or mobility going on? or is the NAS configured to pass through the details after client has a known address? anyway, full debug - but your server is old old old so no further help from me. alan
