Well put.. :) > Just go for it. The slirp code was imported into qemu. At this point > you're probably as much an expert as anyone.

Well, in this case, it is almost worth pondering if a complete from-the-top rewrite is required... It might be easiest to look at what the code is meant to do, from a high level, and re-implement from scratch. This way, all the required features can be put in from the beginning, no extra stuff that's not required, and so on... I expect large amounts of the code can be kept and modified, and the general layout will remain, but a lot of the data structures will have to go... > If you fix it though, be prepared for the fact that you will be the new > expert ;-) Hhhmmmm.... I have numerous projects I'm already working on; adding one more always gets tricky...

Perhaps we could borrow some of the "iptables" code from the Linux kernel, and use that..? It would be quite cool, I think, to have something similar to iptables built into qemu... -- Paul "LeoNerd" Evans [EMAIL PROTECTED] ICQ# 4135350 | Registered Linux# 179460 http://www.leonerd.org.uk/
