We are running with 128 or so, no problem so far (with apache). I've set up one apache daemon for every 32 virtual servers in the case one fails and to have not too many open files per process. The box works like a champ (only P5-133) due to the superior VM/task sheduler of FreeBSD. > The max number of IP aliases is 255 I think per network card. > If I would like to configure 240 ... would that run or > do you see problems ? I'd try that if you don't know. I've seen a mail on that subject sometime last year. It said there should be 'no limit' and he tried it with over 300 (if my memory did'nt fail). One suggestion was to alias your loopback interface with all that ip's and put a static route on your router that points to the whole class-c on your box. This avoids all the ARP entries on your ethernet (and I think the arp tables are not very huge). > What about the maximum number of open files ?
