RE: ADSL Shaper

You will find at everything will be less laggy if you set your maximum
bandwidth to just below your ADSL's bandwidth, this prevents your routers
HUUUUGE buffers from having to be used. It makes your interactive sessions
much more ... Interactive. Interactive being things like ssh. It also is
what seems to help mainly with the downloads detrimentally effecting
uploads. Ultimately you will loose a small amount of bandwidth, but your
latency will improve significantly without any other queues or classes in
use. 

BTW was this thread previously Re: more wireless talk ...sec: unclassified.

Because I posted about lartc.org a couple of days ago... Kratzy, the default
Wondershaper will speed your ssh right up.

Cheers - yeah, I will also packet shape based on IP; it's the way I've done
things in the past on openbsd.  Still, making ssh less laggy regardless
would be A Good Thing.

I came across "dsl_qos_queue" as well (http://www.sonicspike.net/software/),
which looks quite interesting.

Thing is, I'm running 2.4.21 - and random strange things were happening
(i.e.
some of my ipfilter lines were listed, but didn't actually seem to be
working).  I just rebooted back into an older 2.4.19 without all the QoS
stuff I need, and I'm not experiencing these problems.

Hmm.

A bug in 2.4.21 or the version of iproute in Debian (which is dated 2001,
oddly) perhaps?  (Or more likely, I kludged the 2.2.21 compile).
