RE: Simple setup question

Sorry, my mail should have read "AcceptStats 5.6.7.8/32"
 
AcceptStats 5.6.7.8/32 is a short way of writing 5.6.7.8/255.255.255.255,
which in terms of broadcast packets means a single host, eg. 5.6.7.8.
Normally, you'll see people using /24, which means 255.255.255.0. Thus, /24
lets me accept stats from my whole (internal) network.

You might not need the /32 on the end though if mod_backhand can work it out
by itself.

On a completely separate note, if you've got two machines with external IPs,
you might want to look at wackamole to give your webhosting a bit of extra
reliability.

Again, you will probably need to check the exact usage of MulticastStats and
AcceptStats because its been a while since I had to use them, and I don't
have any documentation handy!  Don't be surprised if I've got an IP address
in the wrong place. The main concept is that you're trying to 'multicast'
your stats to a single machine.

Good Luck,

Bryan
