Hi, With FR 2.x I configured stuff so that for locally generated "Health-Check" users I didn't write entries into the back end database. some of these users authenticate every 30 seconds. This worked fine. I've now set up two 3.0.12 servers that write radacctg and radpostauth info into a postgresql back end db. Again everything works fine and I can see appropriate entries in the db tables. What I can't find is where to put my "If auths from this client don't write to the db" clause in my sites-enable directory files. I thought something like if ("%{client:shortname}" != "systems0") { -sql } would work but FR is hanging in there and still writing the users into the db. I should point out that I'm using the "null" sql driver and writing accoiunting and postauth stuff into a text file with radsqlrelay actually doing the job of getting the data into the db. rgds Alex
