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.
This program is a work in progress and it changes on daily basis due to new features being implemented, changes being made to already implemented features, bug fixes, etc. Therefore if the current version is not working as expected try to clone it again the next day or shoot me an email describing the problem. Any input is appreciated. Also keep in mind that some features may be implemented only partially (as needed for stack operation) or they may be implemented in sub-optimal or not 100% RFC compliant way (due to lack of time) or last but not least they may contain bug(s) that i didn't notice yet.

Ostinato aims to be the equal and opposite package to Wireshark, which is to say it is a simple, easy to use (if you know networking, that is) packet generator which lets you construct packets from the physical layer all the way up into individual applications. Can also load, edit, and replay on the wire the contents of PCAP files.
