Or even ipfwadm, if you're still at 2.0. Something like

/sbin/ipchains -A output -t 0x01 0x10 

will set the minimum delay flag on every outgoing packet.

See also the (quite excellent) IPchains HOWTO by Rusty Russell.

Note: the question isn't all that off-topic. The route-cache Linux uses
is keyed on the triple <source address, destination address, type of service>.
I've already encountered a situation in which I *had* to whack the TOS bits
into submission in order to let connections be routed somewhat sanely.

Doei, Arthur. (And yes, that will end up in the FAQ, but not quite yet)
