[[PageOutline]] = DCT3-GSMTAP = DCT3-GSMTAP is a command line utility to capture the GSM Um and SIM-ME interfaces from a Nokia DCT3 phone (eg. 3310) and forward via GSMTAP to the Wireshark protocol analyzer. It is released under GNU GPL version 2. It is heavily based on Gammu http://www.gammu.org and Project Blacksphere http://nokix.pasjagsm.pl/help/blacksphere/sub_200nokiaos.htm which is the result of a great deal of assembly code reading, research, countless (mostly futile) searches for data sheets, cross-referencing and analysing by wumpus blacksphere@goliath.darktech.org (and others in the credits section). = Cable = A serial/USB FBUS cable is required. Images from https://svn.berlin.ccc.de/projects/airprobe/wiki/tracelog [[Image(nokia3310_nk-33.png)]] [[Image(nokia_connect.png)]] = Usage = {{{ dct3-gsmtap device host }}} The device should be something like /dev/ttyUSB0 (check dmesg once plugged in for exact name) or /dev/ttyS0. The host is where to send the GSMTAP packets to (224.0.0.1 is a good option). If you then run wireshark on the relevant interface, you'll see GSMTAP messages. = Author = Duncan Salerno duncan.salerno@googlemail.com - please let me know if you have success with non-3310 phones and I'll add them to the wiki! = Download = The source code is kept in See the main osmocom git repository at '''git://git.osmocom.org/dct3-gsmtap.git''', which you can browse best from http://cgit.osmocom.org/
