Using YateBTS in GSM roaming and GSM dataroam working modes traffic can be captured/analized with Wireshark.
- Enable GSMTAP.GSM capture from the Yate rmanager (telnet 0 5037)
- mbts config TAP Control.GSMTAP.GSM on (GSMTAP.GSM will capture SIP and RTP packages)
- Enable GSMTAP.GPRS capture from the Yate rmanager
- mbts config TAP Control.GSMTAP.GPRS on (GSMTAP.GPRS will capture GTP-C and GTP-U packages)
- To check if GSMTAP is enabled type mbts config TAP in Yate rmanager.
yate-sdr@ybts-UNCONFIG> mbts config TAP Control.GSMTAP.GPRS on Control.GSMTAP.GSM on Control.GSMTAP.TargetIP 127.0.0.1 [default] yate-sdr@ybts-UNCONFIG>
- To capture traffic use tcpdump: tcpdump -i any udp port 4729 -w GSMTAP-yatebts.pcap
- Or Wireshark, already installed on the LatKit/SatSite by adding a custom filter: udp port 4729.
