I've deployed snort listening on bonded eth interfaces successully.
The one quirk, which may have been fixed since, was that promisc
wasn't being passed down from bond0 to the bonded ethN interfaces
when snort tried to set promisc; the simple fix was to explicitly
ifconfig bond0 promisc before ifenslaving the ethN interfaces;
promisc _is_ propogated down to the ethN interfaces at ifenslave
time.

That's weird. I've got one Snort box here using bond0 to aggregate two
i82557/i82558 chipset eepro100 Ethernet cards under Linux, ifconfig doesn't
show "PROMISC" anywhere on anything, and yet it's certainly running promisc
as I'm seeing alerts from non-Snort IP addresses....

[I just love that "bond" feature :-). No cracks about "bond"age please!
;-)]

Thanks for the bond stuff, i'll test it out in a few weeks.

For the interface, i was able to snort the data in the cipcb* and ppp*
interfaces no problem, the only trouble i had was the init script
like the line i pasted, so now i am ok.

So bottom line, we need someone to change the init script in this rpm.
so that it checks other type than ethernet interfaces since many people
use dsl connections and vpn technologies these days.

Anyways
thanks for the comments
