[Twisted-Python] RAW Sockets, IP in UDP
Hi all, I am new to this list, but I have some hopefully simple questions for you. I need to implement a listening RAW sockets which gives me all packets at that particular interface. Next, I need to put this data into a normal UDP container to send it to another host, where it is unpacked again. I am studying all the docs now, but any hints would be greatly appreciated! Thx in advance.

Low level packet handling part of Twisted (twisted.pair) isn't really usable for your use case and hasn't been updated for a quite a long time. As it comes to receiving and sending raw packets you have a few options to choose from.If you don't care about portability you can just use AF_PACKET socket from python's standard library which is supported only on linux.Otherwise you need to use one of many python libpcap wrappers like pypcap, pylibcap or python-pcapy.Not all of them support sending packets.If you choose one that doesn't you can always use python bindings for libdnet. After all that you still have to choose packet parsing/contruction library like dpkt, umit umpa or scapy. -- Kuba

Hi Lars, I had similar issues with the twisted.pair code, so I wrote up my own implementation to do ICMP using Twisted. Grab this file: http://www.seafelt.com/software/sources/seafelt-backend_2.1.2-1.tar.gz extract it, and look at lib/seafelt/icmp.py for some code you might be able to use. -- Justin Warren <daedalus@eigenmagic.com>
