Pytcp
PyTCP is an attempt to create fully functional TCP/IP stack in Python. It supports TCP stream based transport with reliable packet delivery based on sliding window mechanism and basic congestion control. It also supports IPv6/ICMPv6 protocols with SLAAC address configuration. It operates as user space program attached to Linux TAP interface. As of today stack is able to send and receive traffic over Internet using IPv4 and IPv6 default gateways for routing. Since goal of this project is purely educational (at least at this point) the clarity of code is preferred over its efficiency. For the same reason security features are not being implemented just yet unless they are integral part of TCP/IP suite protocols specification.

Installation
If you don't have the Go programming language installed you can download the
appropriate binary for your system from the releases page,
rename it as trawl, and put it in your path (howto ubuntu/howto windows).
I have not tried all of the binaries, so if there's a problem with one let me know, thanks.
If you do have Go installed...
go get -u github.com/robphoenix/trawl
Acknowledgements
I totally used the awesome @jessfraz's battery as a starting point and continual touchstone for how to build this. Trawl is far from perfect, but I've learnt from it, which was more the point.
