Installing Yate from Source on Ubuntu 20.04

Software, VoIP, ,

Here’s my build instructions for compiling and running Yate on Ubuntu 20.04 from source:

apt-get update
apt-get install wget make gcc autoconf subversion libsctp-dev libsctp1 g++ -y
cd /usr/src
svn checkout http://voip.null.ro/svn/yate/trunk yate
cd yate
vi /etc/modprobe.preload

Enable SCTP by adding “sctp” into the file and saving, then we can get on with compilation:

modprobe sctp
sysctl -p
./autogen.sh
./configure --enable-sctp=yes
make
make install-noapi
ldconfig
yate -V

And done, Yate installed with SCTP support, for all your SIGTRAN needs!

Soon we’ll be using this in our series investigating SS7 networks…

Configuring YateBTS for Software Defined GSM/GPRS

GSM, Mobile Networks, RF, Software, , ,

I did a post yesterday on setting up YateBTS, I thought I’d cover the basic setup I had to do to get everything humming;

Subscribers

In order to actually accept subscribers on the network you’ll need to set a Regex pattern to match the prefix of the IMSI of the subscribers you want to connect to the network,

In my case I’m using programmable SIMs with MCC / MNC 00101 so I’ve put the regex pattern matching starting with 00101.

BTS Configuration

Next up you need to set the operating frequency (radio band), MNC and MCC of the network. I’m using GSM850,

Next up we’ll need to set the device we’re going to use for the TX/RX, I’m using a BladeRF Software Defined Radio, so I’ve selected that from the path.

Optional Steps

I’ve connected Yate to a SIP trunk so I can make and receive calls,

I’ve also put a tap on the GSM signaling, so I can see what’s going on, to access it just spin up Wireshark and filter for GSMMAP

Compiling YateBTS NIPC for Software Defined GSM / GPRS

RF, Software, , ,

A lot of the Yate tutorials are a few years old, so I thought I’d put together the steps I used on Ubuntu 18.04:

Installing Yate

apt-get install subversion autoconf build-essential
cd /usr/src svn checkout http://voip.null.ro/svn/yate/trunk yate 
cd yate
./autogen.sh
./configure
make
make install-noapi

Installing YateBTS

cd /usr/src 
svn checkout http://voip.null.ro/svn/yatebts/trunk yatebts
cd yatebts/ 
./autogen.sh 
./configure
make install

Defining location of libyate

On Ubuntu I found I had to add the library location in ldconf:

echo "include /usr/local/lib/" > /etc/ld.so.conf
ldconfig

Installing Web Interface for NIB / NIPC

apt-get install apache2 php
cd /usr/src/yatebts/nipc
make install
cd /var/www/html
ln -s /usr/local/share/yate/nipc_web nipc
chmod a+rw /usr/local/etc/yate/
