I quickly found this to be very tedious and time consuming, so I started looking for a program that would read in the pcap file I'd made with tcpdump, fire the packets at the test server and compare the packet it got back with the response packets in the capture. After some googling I couldn't find anything, so I decided to write one.
Sounds good.
Now I am a developer, but an Engineer, so my C might not be the best, however I've found this very useful and thought other people might also find it useful. It's simple to use and the output is fairly easy to interpret.
OK... my main surprise is that you've re-written a RADIUS encoder/decoder, and a dictioanry file parser. All of that code already exists... The "radsniff" program distributed with FreeRADIUS reads PCAP files. It uses the FreeRADIUS library to read the dictionaries, and the library can send/receive packets. It may have been less work to glue some "send/receive" logic into radsniff. Still, the tool looks useful. Alan DeKok.
