'ping -f -s NNN host' will generate lots of packets of about NNN octets each. be sure to test with various packet sizes. also investigate tcpspray and tcpblast. not sure how up-to-date these urls are (just grep'd them out of debian's /usr/doc/netdiag/copyright) ftp://sunsite.unc.edu/pub/Linux/system/network/admin/tcpblast-19990504.tar.gz ftp://sunsite.unc.edu/pub/Linux/system/network/sunacm/Other/tcpspray/tcpspray.1.1a.tar.gz > what kind of performance of linux based traffic generator could i > expect (in terms of packets per second) ? depends on the generator. ping -f should be able to saturate gigabit on most systems. j. -- all your base are belong to us! - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
