OpenGGSN¶
OpenGGSN is an implementation of the Gateway GPRS Support Node (GGSN) element in the GPRS core network.
OpenGGSN was developed in 2002 to 2004 by Mondru AB and was abandoned for some years before adopted by the Osmocom project around 2010.
Source Code / git repository¶
The source code is maintained in the osmcoom git at http://git.osmocom.org/openggsn/
Binary packages¶
OpenGGSN packages are created as part of the Osmocom nightly debian builds, see NightlyBuilds
Support / mailing lists¶
Please direct any questions regarding use, configuration or development of OpenGGSN to the osmocom-net-gprs@lists.osmocom.org mailing list, to which you can subscribe at https://lists.osmocom.org/mailman/listinfo/osmocom-net-gprs
Building OpenGGSN with kernel-gtp¶
Ubuntu 16.10, kernel 4.8.0-30-generic is used.
- Installing dependencies and build library
libgtpnl
You can install those packages with:
sudo apt install libtalloc-dev libpcsclite libmnl-dev
Please follow instructions provided at [[https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_Source]] in order to install these library and projects:
Information about dependencies between Osmocom projects is given at the above link:
- libgtpnl
sudo make install sudo ldconfig
- libosmocore
- openggsn
./configure --enable-gtp-linux
Following message is shown at end of the command ./configure --enable-gtp-linux
response:
openggsn Configuration: GTP Linux kernel support: yes
This means that appropriate header files are available.
sudo make install sudo ldconfig
Using OpenGGSN with kernel-gtp¶
In order to find out whether gtp.ko module is available we can enter following command:
find /lib/modules/`uname -r` -name gtp.ko
In case of similar output:
/lib/modules/4.8.0-28-generic/kernel/drivers/net/gtp.ko
we can be sure that gtp.ko module is present.
with
sudo modprobe gtp
we are loading module gtp from kernel.
issuing command give us information about gtp:
lsmod | grep gtp
gtp 28672 0 udp_tunnel 16384 1 gtp
