* Explicitly chown /var/lib/osmocom to osmocom:osmocom, instead of relying on systemd to do it when the service starts up. This does not work with the systemd versions in debian 10 and almalinux 8. * deb: Use "useradd" instead of the interactive "adduser" perl script from Debian. This makes it consistent with how we do it in rpm, and avoids the dependency on "adduser". * deb: Consistently use tabs through the file, instead of mixing tabs and spaces. * deb: Remove support for the "dpkg-statoverride --list" logic. This seems to be a rather obscure feature to override permissions for certain files or directories, for which it does not seem to be a good idea to make the postinst script less maintainable. Something similar can be achieved by using your own Osmocom config file in a different path with different permissions. Related: OS#4107 Change-Id: I406ff0d625b02991d580c8382aa4be04dba45a00 |

osmo-sgsn - Osmocom SGSN Implementation
This repository contains a C-language implementation of a Serving GPRS Support Node (SGSN) for 2.5/2.75G (GPRS/EDGE) and 3G (UMTS). It is part of the Osmocom Open Source Mobile Communications project.
OsmoSGSN exposes
- Gb towards PCUs (e.g. OsmoPCU): Various GbIP flavors + Gb/FR/E1
- GTP towards a GGSN (e.g. OsmoGGSN)
- IuPS over IP towards RNCs / HNBGW (e.g. osmo-hnbgw)
- The Osmocom typical telnet VTY and CTRL interfaces.
- The Osmocom typical statsd exporter.
- GSUP (custom MAP-like protocol) towards osmo-hlr
OsmoSGSN implements
- GPRS mobility management
- GPRS session management

History
OsmoSGSN originated from the OpenBSC project, as a separate program within openbsc.git. In 2017, OpenBSC was split in separate repositories, and hence OsmoSGSN was given its own separate git repository.
