Well this just might work. First you'll need to grab the 2.3.5 source code since was easier to make this work off the top of my head. Then apply the attached patch. The options are totally different (also there's no tcprewrite) but something like this should work:
./tcpreplay -i en0 -I $DMAC -k $SMAC -J $SMAC -K $DMAC -c cachefile -w out.pcap \ ~/Desktop/in.pcap You may need to re-run tcpprep w/ 2.3.5 if it complains about cache file versions being incompatible. If you need to use this for something other then HDLC -> Ethernet, you'll need to edit tcpreplay.c and change the default value for l2len to be the length of that L2 header. I've already changed it from ethernet to 4 bytes for HDLC. Hopefully that get's the job done... if not, it'll prolly be a bit. Good luck, Aaron On 8/16/06, Roy S. Rapoport <[EMAIL PROTECTED]> wrote:

So let me ask you this: Given that my life would be gloriously improved if I was able to make this work in the next day or so, and given that I don't need a solution that actually lets you do interesting things -- some horrific kludge that lets me rewrite to ethernet and specify MAC addresses is good enough -- is there some easy way you'd suggest I mangle the code to make this happen? Say, by hard-coding DLT = 1 in some place? -roy
