Priority for 1 PC to download - How To?

Hello !

I need some (perhaps in deep) help for following:

I´ve 2 PC´s (A&B) and 1 Router

"A" is "always on" and is user for downloading, seti webcam, webserver...
this is not my "working PC"

"B" is my prduktion system and should get all the download he can get!
Because i want fast internet when i´m browsing...
A should then get no (or only very very small) downloadspeed´s!

when i don´t download from "B" then all the bandwith shold be at my PC "A"

the switching should go automatically!

Is there any chance to get this?

Tried to search a litle bit but did not get any results for me...
only thing is the "Traffic shaper" in my kernel (but i don´t know how it works and even less how to setup)

Can perhaps anyone give me an step for step guide to do this?

Many thanks to you
Liu

You cannot accomplish this on a workstation; traffic control is something that has to be done on a router.

Unless your router has very advanced capabilities - or it is a Linux box - you cannot actually do this.

hmmm....

i thought about this:

PC A "recognices" that B is transfering data
then it should be able to throttle the bandwith...

is this no way?

My router is a 35 allnet router - it has very limited functionality :-)

No, because how would that PC throttle or control the bandwidth that PC B is getting ?
Only a network device that has both data coming into it and going out can do any kind of traffic control.

Ergo, a router.

A quick fix but you could proberbly throttle the max bandwidth on system A, however it would be throttled all the time. Also remember to throttle the uplink speed as well.

Erm... the uplink speed is the only thing you can throttle - how would you control how much data is sent to your machine ?

The only way is to drop packets, and hope the TCP mechanism saves your arse...

Thanx -
so i see there is no opportunity to do this!

only thing is to buy a new router with hardwaresupport for this....

(to expensive.

Actually, if you happen to have an old 486 or (slightly better) a Pentium lying around, you can run a dedicated firewall every bit as solid as a Cisco PIX.
You need a box, a Pentium, 32 or 64 MB RAM, 2 NICs and a small HD (around 1GB is plenty).
Then download and burn ipcop and set it up.
30 minutes, tops.

Actually, you can set up any kind of Linux router you like on a small box with dual NICs, but I happen to like ipcop, as it is dead simple to use and includes a wondershaper interface for bandwidth management.
