Tc: ingress policing and ifb mirroring

linux-howto

http://serverfault.com – I'm trying to setup traffice shaping on a Linux gateway as written here. The script needs to be customised because I have multiple LAN interfaces. So to shape the LAN side I am planning to create a ifb psedo devise like so: modprobe ifb ip link set dev ifb0 up /sbin/tc qdisc add dev $WAN_INTERFACE ingress /sbin/tc filter add dev $WAN_INTERFACE parent ffff: protocol ip u32 match u32 0 0 action mirred egress redirect dev ifb0 The script from the gist repo mentioned above has these lines: /sbin/tc qdisc add dev $WAN_INTERFACE handle ffff: ingress /sbin/tc filter add dev (HowTos)

Stories similar to Tc: ingress policing and ifb mirroring

Is there an equivalent of LinuxIMQs in BSD ?

From linuximq.net:

The imq device has two common usage cases:

Ingress shaping:

With linux only egress shaping is possible (except for the ingress queue which can only do rate limiting). IMQ enables you to use egress qdiscs for real ingress shaping.

Shaping over multiple interfaces:

Qdiscs get attached to devices.

So I want to limit the download and upload speed of a specific ip adress in a local network. To do this I are using a bach script running in a linux OS (Ubuntu 11.04). The issue here is that the upload shaper does not work.

modprobe not found at all 34 weeks 18 hours ago

I know that a lot of people had problems finding modprobe which was mostely due to an unconfigured $PATH. This time however I logged into a machine (Linux mymachine 2.6.32-6-pve #1 SMP Mon Jan 23 08:27:52 CET 2012 i686 GNU/Linux with root rights) and modprobe wasn't found at all.

I'm trying to limit traffic to test performance of some in-house applications, but I am getting inconsistent results when configuring my home PC and my company testbed.

The goal is to police the rate to 256kbps, which works as expected at home (tested by wget), but when I repeat the same test on the company testbed, the rate drops to 20KBps.

I have installed squid proxy server at server side so that all PCs connected to the server will access internet through it.I have made changes in squid.conf file also.I have added these two lines:- acl localnet src 192.168.0.167 192.168.0.0-192.168.0.250/255.255.255.0 http_access allow localnet

After I execute iptables, it shows

Usage: /sbin/modprobe-bin [-v] [-V] [-C config-file] [-n] [-i] [-q] [-o <modname /sbin/modprobe-bin -r [-n] [-i] [-v] <modulename> ... /sbin/modprobe-bin -l -t <dirname> [ -a <modulename> ...] Usage: /sbin/modprobe-bin [-v] [-V] [-C config-file] [-n] [-i] [-q] [-o <modname /sbin/modprobe-bin -r [-n] [-i] [-v] <modulename> ...

QOS using tc 34 weeks 1 day ago

Hello all my friends

Please Read to understand my problem

I have 1 MB bandwidth and two networks then i did traffic control on my two internal interfaces i.e eth1(192.168.3.0/24) and eth2(172.16.3.0/24) (internal) and eth0 (outside)

Then i divided my bandwidth using tc command with the help of my friend

On eth1 :---

tc qdisc add dev eth1 root tc qdisc add dev eth1 root handle 1:0

I have 2 question about this game Does ingress will still works if there's no internet connection? I have wifi on my house but outside there's none. Is ingress will just collect data until its connected on the internet again?
