OsmoGGSN is developed by Harald Welte, Holger Freyther, Pablo Neira and sysmocom GmbH. It is baed on the earlier OpenGGSN which was developed in 2002 to 2004 by Mondru AB and was abandoned for some years before being adopted by the Osmocom project around 2010.

Binary Packages

Osmocom provides binary packages for several flavors of Debian and Ubuntu GNU/Linux on a variety of architectures (i586, x86_64, armhf, armv7l). Unless you are a software developer interested in developing on Osmocom, it is recommended you use those packages instead of building from source.
