I've already setup FreeRADIUS on multiple redundant servers, but never had the time to write a HOWTO. The main guideline is: 1. Use LVS in a "direct routing" setup to dispatch the RADIUS requests. http://www.linuxvirtualserver.org/VS-DRouting.html 2. Use MySQL replication for the authorize database, so each FreeRADIUS server connects to a local, read only database. http://dev.mysql.com/doc/refman/5.1/en/replication.html 3. Use radsqlrelay for the accounting database, so the accounting data is written to a central database without slowing down the RADIUS servers. radsqlrelay is to be found in the FreeRADIUS source tarball, you could read the "rlm_sql_log" and "radsqlrelay" manpages for more details. -- Nicolas Baradakis - List info/subscribe/unsubscribe?
