What kind of rule is that? does your client build up a connection from low
ports to low ports? My computer doesn't do that. But to answer your
question:

iptables -A OUTPUT -s HOSTB -d HOSTA -p 6 --dport 21 -j LOG

will solve your problem.

put in that second rule.

Using PRIO qdisc

[Andreas Wright]

[-- Attachment #1: Type: text/plain, Size: 465 bytes --]


Hello ,

I want to use PRIO qdisc to priortize packets coming from a known IP address.Can I specify a filter along with PRIO qdisc instead of using the default priomap.

tc qdisc add dev eth0 root handle 1 : [filter]

If such a filter is possible what would be the syntax for specifying the IP address for example 1.2.3.4

Regards,

Andreas.

Multible Links with Transparent Cache

[hare ram]

Hi all

i am running with RedHat 7.3 with iptables + transparent Cache
its working well

no i have added another Link to My network with another Provider
now i want to Load Balance with Two Links

At now iam running both with 2 Different Server,

iam planning to do below

 eth0 with Public IP x.x.x.x gateway x.x.x.1
 eht0:0 with Private IP (ADSL)  which is provided another Provider
192.168.3.2 gateway is 192.168.3.1

i have LAN with 2 networks at this moment with 2 servers

one Server Serving 192.168.2.0 network Going to First Link
another Server Serving 192.168.20.0 network Going to Second Link

i want  to load balance with this two network with One Server with
Transparent cache,
the cache and routing should automatically load Balance the Links

one link is 128kbps another is 256kbps Link

any one recomend how to do this

Re: Multible Links with Transparent Cache

i'm on a redhat 7.3 with kernel 2.4.19-pre9 patched from 
http://www.linuxvirtualserver.org/~julian/#routes-2.4 and buildt with 
multiple routes
and almost everything else under routing and netfilter, as described in the 
http://www.linuxvirtualserver.org/~julian/nano.txt howto. It's not as hard 
as it seams at first glance. Actually the only thing you need is a static 
ip for both your uplinks and go through the howto and your done.

/Rasmus

I'am using HTB, but to the best of my knowledge CBQ should work just as well.
