Problem with "Address already in use".

[JNS456123]

I have been running into a problem running the script.

First terminal command: python3 simple_IMSI-catcher.py Second terminal command: grgsm_livemon -f 869.2M If I run the first terminal first, then start the command in the second, the second terminal errors out as follows:

pi@raspberrypi:~ $ grgsm_livemon -f 869.2M qt5ct: using qt5ct plugin gr-osmosdr 0.1.4 (0.1.4) gnuradio 3.7.13.4 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy airspyhf soapy redpitaya freesrp [INFO] [UHD] linux; GNU C++ version 8.2.0; Boost_106700; UHD_3.13.1.0-3

However, if I run the command in the second terminal first , then run the command in the first, the first terminal errors out with:

pi@raspberrypi:~/IMSI-catcher $ python3 simple_IMSI-catcher.py Nb IMSI ; TMSI-1 ; TMSI-2 ; IMSI ; country ; brand ; operator ; MCC ; MNC ; LAC ; CellId ; Timestamp Traceback (most recent call last): File "simple_IMSI-catcher.py", line 553, in udpserver(port=options.port, prn=find_imsi) File "simple_IMSI-catcher.py", line 502, in udpserver sock.bind(server_address) OSError: [Errno 98] Address already in use pi@raspberrypi:~/IMSI-catcher $

It looks like something is trying to open the same UDP port in each of these two scripts. I've done a git pull to get the latest version.

Please note the strikeout script is being added automatically by the editor, so that strikeout should be ignored.

What do I need to do to get this working?

Platform Raspberry Pi 4, running Raspbian GNU/Linux 10 (buster)

I think I found the problem: You need to run the script as:

sudo python simple_IMSI-catcher.py --sniff
