LARTC - Jan 2005 - iproute2 + iptables - match the connection time or packets sent/recieved

Hello,

I setup iproute2 and iptables on my box, is a P4 2000 Ghz / 1GB memory.
I have setup squid and iptables to be a transparent proxy, with cache.
I''ve read on lartc.org almost everything and i want to ask if there is
a u32
match for the connection time or something like that, or an u32 match for
the packet number in a connection.
All i want to do is shape the web traffic for long conections wich are not
HTML webpages, i want to slow down those connections.
I know that can be overriden by stopin/resuming the transfer but i still
want to do it since people start downloading  from HTTP with many
connections, during the day and leave the office, i have no time to hunt
them, so i just want to classify those connections if is possible.

If there is any patch for squid to classify URLS would be great, i`ll just
put html/php/jsp/etc.. in the priority class.


Toto

Sure, you can do that with the connbytes Netfilter module.  After someone 
downloads some given amount of data you can reclassify that traffic from 
interactive-Web to bulk-Web or something similar.  I''ve been meaning to
do
this myself, but haven''t gotten to it.

Thanks a lot !
That was very usefull.
I had some problems patching the kernel (I had to do it manually) since my
gentoo kernel is already patched with a lot of other patches, but i managed
to do it and works like a charm.
