Hi, I don't know if something similar exists already but I've created a patch to add the ability to do pcap capturing on dahdi cards. So I'm posting it here just in case it might be useful to someone. It consists of 2 parts 1. changes to the dahdi driver to add ioctls to mirror reads/writes from a signaling channel to a pseudo channel 2. a corresponding user app to set up the mirroring and record the traffic in a pcap This seems to work though I'm not sure if it's the best solution design-wise. I might be abusing the pseudo channel concept and wanted to ask if you ever felt the need for similar functionality. to compile the app do the following gcc dahdi_pcap.c -o dahdi_pcap -lpcap and the syntax to run it is ./dahdi_pcap chan1 [chan2]* pcap.pcap e.g. ./dahdi_pcap 16 47 test.pcap Regards, Torrey -------------- next part -------------- A non-text attachment was scrubbed...
