From the man page (man dummynet): DUMMYNET(4)FreeBSD Kernel Interfaces Manual NAME dummynet -- traffic shaper, bandwidth manager and delay emulator DESCRIPTION The dummynet system facility permits the control of traffic going through the various network interfaces, by applying bandwidth and queue size lim- itations, implementing different scheduling and queue management poli- cies, and emulating delays and losses. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You can use dummynet to create a pipe with arbitrary packet loss and delay, then run particular interfaces (or anything that can be matched via an ipfw rule) through that pipe. See the dummynet and ipfw manpages. -- Dan Nelson [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Run 'man ipfw' for details. --bm ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
How to drop a packet
I'm using a FreeBSD box as a router in a test network. For the tests that I am running, I need to be able to drop random packets and observe the effects (responsiveness). What utilities in FreeBSD or C will allow me to perform the function of dropping a random packet?
