Hi
I need to add new capture filters in ethereal-0.8.18 to support two
propietory protocols.
One protocol is over PPP and the other is over UDP.
Each of the propietory protocol in turn has other propietory or internet
protocols over it....just like encapsulation / tunneling.
1) How do I go about it ??
Do I need to
a) change the BPF filters in side the kernel
b) or the LibPcap source code
c) or just use the LibPcap interfaces ??
2) This is required in both Linux and Windows version of Ethereal. So
code modifications needs to be portable.
3) The capture filter needs to be stateful. Is it possible to create a
stateful capture filter?
Thanking in advance for any pointers / guidance.....
Regards
Diwakar
