TCP Retransmissions

Ordinarily, you're a terrible place to get code, /prog/, but I must yield.

I'm having trouble with AES encryption increasing on packet retransmissions, so I obviously must detect and discard retransmissions for encryption purposes. Since I'm using WinPcap, I figured that Ethereal would be a good place to go to see how it detects these events. I was wrong.

I can't tell what the shit is going on with such ugly C code. Any of you have an enterprise-level solution to retransmission detection? Thanks for your time.

Not really. Testing on my home network connecting to an enterprise network at the moment. Interestingly enough, the stream that goes from here to there breaks first 100% of the time with my last version.

I moved the code to the dispatch spot instead of a higher scope and it seems to be faring much better. I also increased the number to 200.

However, I still have increased issues with just plain not dispatching any more packets period. On a positive note, it doesn't seem like the encryption is falsely increasing .. in my limited testing.
