I've thought a bit about this, but mostly as an exercise of interest rather than need. Packetfence on a single server is performing quite sufficiently for our needs.. :) BUT.. Just as an exercise.. Yes, and external load balancer, external or replicated database, and a way to sync the config. Though if the majority of the config were put into the database *COUGH* that would help quite a bit as well. > Other thing to consider are DHCP, DNS and SNMP (if required). DHCP and DNS are incredibly easy to make active/active with just two servers. SNMP might be interesting, though.. Which server would you need to send a trap to? Would it matter? Other interesting thoughts include how to handle the periodic cleanup routines, no real need to run them twice. And how are messages from switches handled? Do you load balance radius, or alternate configs on the switches, swapping radius IPs back and forth? Are there any other situations where duplicate messages would hit packetfence? > Regards, > -- > Louis Munro -- --------------------------- Jason 'XenoPhage' Frisvold xenoph...@godshell.com --------------------------- "Any sufficiently advanced magic is indistinguishable from technology.\" - Niven's Inverse of Clarke's Third Law ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
