OpenGGSN - Open Source GGSN
===========================
This repository contains a C-language implementation of a GGSN (Gateway
GPRS Support Node), a core network element of ETSI/3GPP cellular
networks such as GPRS, EDGE, UMTS or HSPA.
OpenGGSN is part of the [Osmocom](https://osmocom.org/) Open Source
Mobile Communications projects, even thogh it was previously developed
by Mondru AB.
Homepage
--------
The official homepage of the project is
https://osmocom.org/projects/openggsn/wiki
GIT Repository
--------------
You can clone from the official libosmocore.git repository using
git clone git://git.osmocom.org/openggsn.git
There is a cgit interface at http://git.osmocom.org/openggsn/
Documentation
-------------
There currently is no other documentation other than the wiki on the
homepage. It would be great if somebody would work towards a user
manual that can become part of the osmo-gsm-manuals project.
Mailing List
------------

*Tun*
The tun driver is required for proper operation of openggsn. For linux
kernels later than 2.4.7 the driver is typically included, but need

Installation from binary
------------------------
rpm -i openggsn-<version>.rpm
This will install binaries, man pages, configuration files as well as
a Sys V init script for the ggsn.
OpenGGSN is built for common versions of Debian and Ubuntu as part of
the [Osmocom Nightly Builds](https://osmocom.org/projects/cellular-infrastructure/wiki/Nightly_Builds)
project. If you don't want to do development, it is suggested to simply
use those binary packages, rather than building yourself from source.

This is quite good. It means that you managed to send off an echo

you did not get an echo response it means that something is wrong
