Ten years back when I was a netadmin I faced the problem of implementing traffic shaping of some sorts. Details don't matter much. After a very short while I learned that ip was the solution to my problem. One week later I started digging into the kernel code because I simply couldn't work out how to use this thing. Another week later I was playing with the idea of writing my own traffic shaper in the kernel instead. It was that bad. Then I found something called tinybsd, a bsd distro on one floppy disk. We allotted an old 486 with two network cards, I spent some uncomfortable time configuring the beast with the crappy editor you can expect on 1.44MB and the thing just worked henceforth. Oh, the bsd had their equivalent of ip tightly coupled with their kernel. Not sure if that caused the marked difference, but I'll gladly add this shred of anecdotal support. [ And in case someone takes offence or considers me an idiot for not being able to use ip or tc, I would _love_ to see a howto explaining how one can limit the amount of traffic on one interface to - say - 1GB per month. ] Jörn -- Write programs that do one thing and do it well.
