Hey guys, I am planning to buy some components for a Linux router that will handle the Internet access of 200 computers (includes tc shaping) and some inter sub-network routing (at least 100MBps per eth - and there are 3 eth cards). I was thinking of a: Pentium 4 - 3GHz 256 or 512MB RAM Network Cards. Now - I wonder what is more important: the processor speed or the amount of RAM. And can you

Hello guys! I have the following setup: Linux router acting as a gateway for several subnets in the LAN. The subnets are: 127.17.0.0/16 (will go out via NAT) 195.229.x.x/24 193.289.y.y/28 213.189.z.z/26 etc. There are about 20 subnets including the private Class B subnet. I want to mark the packets that will go on the Internet, and leave out the packets that move from one subnet to the

Hello, I just compiled a new kernel.iptable/iproute2 to fresh up my router. There is a little problem... The fw classifier does not work in tc. I read some note found in the source of iproute2 and it says: "* To use "fw" classifier you will need ipfwchains patch." I can''t find this patch. Do you have it? Is there any other way to implement the "fw"

Hello guys, I need to accomplish 2 tasks with one Linux router: 1) Shape the traffic based on services (e.g. HTTP max 512 kbps, P2P max 128 kbps - with a lower prio, etc) 2) After I have classified the traffic based on services, I want to pass it to the clients with different rates/ceils (one client will get 8/128 kbps, other 8/64 kbps, etc). If all the users are downloading via P2P I do not

Hello again, I am stuck with this problem: I have: One Linux NAT Box. One internet connection. 100 clients in the LAN. Test 1: - Connect only one client to the server and download from it a file. -> The total speed recorded on the server is maximum (as expected - let''s say 128KB) Test 2: - Connect all 100 clients (somewhere in the evening) and let them browse - download, etc -

Hello again, I need to change the R2Q for my script, as setting the quantum manually for each class is painful. Can you tell me exactly where to set R2Q = x? I get syntax errors all the time. Should it be specified for each class? I do not know where to place this setting... Thanks in advance, Vlad Mihai

Hello again, Is it possible to split a bandwidth equally among clients regardless of its current link speed? I have a link that can get bursty at times. At any given time the N active sessions (the ones with non-empty queues) need to be serviced simultaneously, each at a rate of 1/N''th of the link speed. My case is an internet connection that oscillates between 96 kbps and 256 kbps. I

Hello, Is there a way to route p2p traffic on a separate ISP connection, just as you would choose a separate connection for http traffic? I tried all sorts of setups based on: http://www.braindump.dk/en/wiki/?wikipage=PolicyRouting but with no luck. Please help :) (ipp2p is up and running) _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

I have a tc script which splits the bandwidth in 8 leaf classes based on IP filtering. The script looks like this: tc filter add dev $LAN_IFACE protocol ip parent 1:0 prio 1 u32 match ip dst 192.168.0.121 flowid 1:11 The separation works excellent for downloads, but for uploads, it is ignored... Can you tell me how to deal with it? Thanks in advance, Vlad Mihai

Thanks, The only issue here is that for each service I need to create 200 child classes if I have 200 clients... Let me explain the problem better I have the following connection from my ISP: (1024/1024) (rate/ceil) 1) First, I want to divide the 1024 into smaller pieces based on priority: 256/256 - P2P (I want to limit the P2P traffic as much as possible) 256/1024 - HTTP 256/1024 - FTP

Hello again, I have a router/nat linux box. I managed to create some HTB classes and everything is OK. When perople are usig download managers like FlashGet and DAP (multiple connection ones), the ceil limiting works okay, but the rate parameter is somehow useles... The guaranteed bandwidth is never reached. So what can I do to limit the number of connections/computer? I want to make sure that

Hi guys, Can you take a look at this? :) +-----------+ | | eth1-|- | | -|-eth0---LAN--- | | eth2-|- | | | +-----------+ - eth0 is connected to the LAN having the IP=LAN_IP eth1 is connected to the first ISP having IP=ISP_IP_1 and GW=ISP_GW_1 eth2 is connected to the second ISP having IP=ISP_IP_2 and GW=ISP_GW_2 I need

Hello again, I may have a common problem to solve but it seems it is harder than I thought... I have 2 internet providers (each one having a different gateway). Behind the router there are around 100 clients that are SNAT-ed. I want some clients to be SNAT-ed to the first provider, while the others to the second one. The following lines should work: iptables -t nat -A POSTROUTING -s
