Today I added SNMP agent support to a very slim tool called trafd, which can be used to keep statistics on host-host traffic. With the Radiotap stuff I've committed to the new tcpdump port this week, it isn't too much of a stretch to extend support to trafd. The idea is that radiotap could be used to provide a means of collecting signal quality statistics, per-node, on a FreeBSD host, with SNMP agent support. (*) This will allow node builders to use the many excellent tools out there based on MRTG and RRDTOOL, such as Cricket, to provide network monitoring and time-series graphs. Pretty essential if you're planning a wide community network rollout. I'm getting pretty close to a working prototype. I'll post details here when I have something people can run and play with. BMS (*) I'm aware of the fact that the Atheros code keeps various RSSI stats inside. I'll be looking to push some of the housekeeping back into the kernel so that hacks such as trafd aren't needed, and the SNMP agent component would shrink as a result. --/04w6evG8XlLl3ft Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Comment: '' iD8DBQE/2fq3ueUpAYYNtTsRAiE0AJ4w0hOZpDHOKOBAo9YJsxDukf8amACfaTPU u85RxSQ+6uHU27nHYJAHVEI= =4HmG -----END PGP SIGNATURE----- --/04w6evG8XlLl3ft--
