#
# Build the IMSI LOGGER on Ubuntu 18.04 like this:
# Install Ubuntu 18.04
# .. then login so you have a shell / prompt..
# Install sudo - or shift user to root
su - root
apt-get update -qq -y && apt-get install -y sudo
# Install pre. reqs.
sudo apt-get install python-qt4 python-apt python-pip gr-gsm git python-numpy python-scipy python-scapy
# The two next steps might not be needed - then just skip them !
# 1/2) Get an updated version of grgsm_livemon here
cd /tmp ; wget http://git.osmocom.org/gr-gsm/plain/apps/grgsm_livemon.grc
# 2/2) Compile it and overwrite the older version
/usr/bin/grcc -d . ./grgsm_livemon.grc
sudo mv ./grgsm_livemon.py /usr/bin/grgsm_livemon
# Start the grgsm_livemon gui
sudo grgsm_livemon
# In another shell / terminal window:
# Get the IMSI extract script from GIT
cd ; mkdir source ; cd source ; mkdir IMSI; cd IMSI
git clone https://github.com/Oros42/IMSI-catcher.git
cd ./IMSI-catcher
chmod 700 ./simple_IMSI-catcher.py
# Run the script
sudo ./simple_IMSI-catcher.py -s
# That was it - now tune to the right Freq. and see the IMSI/TMSI numbers.
