Open CGF

I have started a project called open-cgf that should address this need. It is currently still being developed, but does accept and decode GTP' for UDP, and I've just started implementing the other messages. It doesn't decode the ASN.1, but will (shortly) write them to disk in encoded format -- without the GTP' header. Decoding ASN.1 CDRs is another project I'm working on.

Coupled with this is will be a test program to exercise it, which should be useful for people implementing CGF's too...

I will be relying on people to test this and report faults as I cannot test it directly. Traces from an existing model network would be appreciated...

You will need to install Erlang before you can run the CGF -- and I've not yet written the instructions for that either Smilie

Development is proceeding quite quickly.

If you want to start using this please drop me a line.

NAME

       xl2tpd - Layer 2 Tunnelling Protocol Daemon

DESCRIPTION

       A Layer 2 Tunneling Protocol VPN client/daemon for Linux and other POSIX-based OSs. Based off of L2TPd 0.61 from
	 http://www.marko.net/l2tp and patches collected by Jacco de Leeuw at
	 http://www.jacco2.dds.nl/networking/openswan-l2tp.html

       Currently maintained by Xelerance

       -p <pid file>
	      Tells xl2tpd to use an alternate pid file.  Default is /var/run/xl2tpd/xl2tpd.pid

       -C <control file>
	      Tells xl2tpd to use an alternate control file.  Default is /var/run/xl2tpd/l2tp-control
