Weird. It shouldn't choke on that. > 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. If you are going to put lots of webservers on a machine, alias the IPs onto lo0 and treat the ethernet interface as the gateway for other machines to send packets to VWS network. My webserver 203.29.224.19 (de0) has all of 203.8.13.0 and half of 203.8.12.0 on lo0. My router has the equivalent of route add -net 203.8.12.0 -netmask 0xffffff80 203.29.224.19 route add -net 203.8.13.0 203.29.224.19 Basically, there is no limit to the number of IPs you can put on a machine. 5000 was tested once.. > What about the maximum number of open files ? You should build with something like MAXUSERS=256, OPENMAX=1024 and something reasonable for CHILDMAX. Hmm, I really should write a Handbook section on this... regards, Danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
