While it requires a serious paradigm shift, Wackamole (http://www.backhand.org/wackamole/) provides N:M IP redundancy on *BSD + linux/windows/solaris. Down sides: not quite as transparent, no MAC stealing, but uses grat. ARPing to announce failures. Upsides: you have have more than two machines (N) and you can offer services over more than one IP (M). We run it on some static image server clusters as well as some relatively high throughput FreeBSD 4-stable routers running normal IP forwarding, natd and endpointing many IPSEC VPN tunnels. It's a pretty different solution than CARP. More useful in some places, less appropriate in others. // Theo Schlossnagle // Principal Engineer -- http://www.omniti.com/~jesus/ // OmniTI Computer Consulting, Inc. -- http://www.omniti.com/ // Ecelerity: fastest MTA on Earth
