[Tomahawk-devs] Traffic Generation Problems

[Steve S. <ss...@ll...>]

Hello,

We're having some problems with tomahawk correctly replaying our pcap 
file.  We have a pcap file with 9 packets in it, 6 in one direction, and 
3 replies in the other, so only 2 addresses total.  It's a very simple 
pcap we've been using for debugging.

The problem is that only the primary interface spews out any packets. 
It's not a hardware/OS issue, since any interface works, so long as it's 
specified by "-i" and not "-j".

In the SendPackets function, I've noticed that on/around line 1436 of 
tomahawk.c, we check the handler to see if it's in "attacker" mode, and 
if so, writes out to the primary interface.  I put printf statements in 
each conditional branch to demarcate when each was happening, and it 
appears that h->attacker is always set to 1, which means that the 2nd 
interface never gets to fire.

I see that in RecvPackets, there is code to "switch" modes, but it never 
seems to trigger.  Also, it seems that every packet in the trace has an 
attacker flag, but this is never referenced for updating, at least as 
far as I can tell.  I'm still working on understanding the code, but I 
was hoping someone else had run into this and may be able to shed some 
light on this - maybe we could work at rolling out a Tomahawk 1.1 :)

Any thoughts/fixes?  Thanks!
