when someone asked me to do something like this, i waded through caida's site and came accross this: http://www-iepm.slac.stanford.edu/pinger/ it's pretty cool stuff. requires *nix box, perl5, and some sort of webserver software to produce simple reporting. there's also (optionally) utilities that draw some pretty graphs that require gnuplot/ppmtogif. imho, this is considerably better than logging into your router to do this. routers are much better at forwarding packets than sending/receiving them. (except older non-distributed routers, which aren't particularly great at either for high traffic volumes) other bonus: no automated sending of passwords from a box that might not get much admin attention. one could probably modify these tools to use fping, but i just played around with them for edutainment purposes. there's no mention of copyright that i can find, but one should ask before using for commercial purposes.
