Anyone doing bw limiting with cbq or iptables?

Yeah, unfortunately it's on a managed switch, but one that can't limit 
rates.

That's how I've found it.. lots of docs, but none that are very clear, at 
least to me.

Hmm.. more of the same data.  The cbq script and files I setup are putting 
the same kinds of commands in play, but even when I drop settings down to 
something tiny like 1bps it doesn't seem to effect transfers.. getting 
frustrated.  

I'm going to be mad if it's like older ipchains stuff where once you setup 
one high value (I had first values kinda high until I read that Kbps to it 
was k bytes/sec not k bits/sec) that you have to reboot to really clear out 
the old settings to get new ones in instead of just clearing the tables.  I 
used to have issues like that with ipchains a couple years ago.
