Fedora 7 Launch

[Damian Myerscough]

Hey Mike,

I have seen:

if you want to balance the load to the 3 addresses 10.0.0.5, 10.0.0.6
and 10.0.0.7, then you can do as follows :

# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3
--packet 0 -j SNAT --to-source 10.0.0.5
# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3
--packet 1 -j SNAT --to-source 10.0.0.6
# iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 3
--packet 2 -j SNAT --to-source 10.0.0.7

Do you have a box that can act as a dedicated balance loader while FC
7 is being released
