I've to confess I've quite limited knowledge with TCP/IP stack internals, e.g. the way stack extensions work et cetera.

Does anyone know of any available online visual materials/tutorials? I'm particularly searching for tools capable of recording and replaying TCP/IP stack packets with visual representation, references to RFCs and specifications.

The author uses the customized settings for his TCP stack and then laments that some nodes on the internet which aren't under his control depend on more common settings. Honestly I don't see why he could have expected any different outcome.

Coursera and stanford mooc helped me understand networking deeper, you might try to apply.

The other node doesn't depend on the settings, it depends on not receiving a duplicate SYN.
