add template-configs, script to launch network
This is the set of scripts I've written for myself over the years to easily configure and run Osmocom core networks on my lab computer. I hope this will be useful to others as well.

=== WHAT IS THIS?
|
||||
|
||||
* quickly build the entire Osmocom core network stack from source, with a
|
||||
generated top-level makefile (see the rest of this README file below).
|
||||
|
||||
* quickly configure, launch and tear down an entire Osmocom core network on
|
||||
your box (see net/README).
|
||||
|
||||
|
||||
=== Quick Start
|
||||

=== WHAT IS THIS?
|
||||
|
||||
* quickly configure, launch and tear down an entire Osmocom core network on
|
||||
your box (see net/README).
|
||||
|
||||
This is the set of tools I wrote for myself and use every day to run and test
|
||||
the Osmocom core network. I hope this helps, and I would appreciate
|
||||
contributions of any improvements you may have!
|
||||
|
||||
|
||||
=== Quick Start
|
||||
|
||||
cp config_2g3g config_mine
|
||||
$EDITOR config_mine
|
||||
# update IP addresses and device names as required
|
||||
|
||||
mkdir my_network
|
||||
cd my_network
|
||||
../cfg.sh ../config_mine ../tmpl_std
|
||||
|
||||
./run.sh
|
||||
# Launches numerous x-terminals with one component running in each.
|
||||
# Logs and pcap traces are being taken automatically.
|
||||
|
||||
# hit enter in the original first terminal to tear down all programs.
|
||||
# Enter a name to save logs, otherwise all logging will be stored
|
||||
# under autolog/<timestamp>
|
||||
|
||||
Then possibly modify the config and refresh:
|
||||
|
||||
# tweak config?
|
||||
$EDITOR ../config_mine
|
||||
../cfg.sh
|
||||
# picks up same ../config_mine and ../tmpl_std from last time
|
||||
|
||||
# own templates?
|
||||
cp -r ../tmpl_std ../tmpl_mine
|
||||
$EDITOR ../tmpl_mine/*
|
||||
../cfg.sh ../tmpl_mine
|
||||
# picks up same ../config_mine from last time, and ../tmpl_mine from cmdline
|
||||
|
||||
|
||||
|
||||
=== Config file templates
|
||||
|
||||
A *directory* contains template files that are filled with specific values by the
|
||||
cfg.sh script (aided by fill_config.py). See e.g. tmpl_std/.
|
||||
|
||||
A *file* contains local config items that are put into the templates. See e.g.
|
||||
config_2g3g.
|
||||
|
||||
The cfg.sh script helps to fill the templates with the config values. Simply
|
||||
invoke cfg.sh with a dir argument (templates dir) and a file argument (specific
|
||||
config values).
|
||||
|
||||
If one or both are omitted, the script tries to re-use the most recent paths,
|
||||
they were stored in local files '.last_config' and '.last_templates'.
|
||||
|
||||
The result is a complete set of .cfg files that match your local machine and
|
||||
network config.
|
||||
|
||||
|
||||
=== Launch
|
||||
|
||||
A run.sh script template (tmpl_std/run.sh) also gets filled with specifics and
|
||||
placed next to the .cfg files.
|
||||
|
||||
run.sh uses sudo to start tcpdump, configure ip forwarding and masquerading
|
||||
(for the GGSN's APN tunnel required for data services).
|
||||
|
||||
When you launch run.sh, many xterms are launched, and when hitting enter, all
|
||||
of them get destroyed again. This is obviously intended to be run on your
|
||||
desktop computer or laptop, not on a remote box. It may also make sense to
|
||||
launch all of them in the current shell, and maybe or maybe not switch off
|
||||
stderr logging; or to launch each component in a tmux window or whatnot -- if
|
||||
you figure out something in that line, I would be glad to get contributions and
|
||||
incorporate that.
|
||||
|
||||
|
||||
=== Logging and pcaps
|
||||
|
||||
The run.sh script automatically stores all configs, logs and pcap traces in
|
||||
./autolog/<timestamp> dirs. After closing the components (by hitting enter),
|
||||
you may also enter a name for the logs, after which they are stored in
|
||||
./logs/<name>. The idea is to keep all important logs with a name, and that you
|
||||
can every now and then just 'rm -rf ./autolog' to make space.
|
||||
|
||||
|
||||
=== 3G
|
||||
|
||||
You may notice that the templates include nano3G.txt files. These include a
|
||||
convenient listing of commands to connect to an ip.access nano3G DMI and
|
||||
connect it to the HNBGW as configured by the templates.
|
||||
|
||||
|
||||
=== 2G BTS
|
||||
|
||||
At the time of writing, there are no osmo-bts.cfg files, since this is intended
|
||||
for the core network and BSC components only. Feel free to add!
|
||||
|
||||
Typically you'd need to edit only the /etc/osmocom/osmo-bts.cfg to match your
|
||||
IP address and ipa unit-id:
|
||||
|
||||
bts 0
|
||||
oml remote-ip 192.168.0.123
|
||||
ipa unit-id 1800 0
