Hello Mathew,
Yes, it is all clear and your setup should work provided you changed the
few tiny bits I suggested.

Best,

[LARTC] Simple Rule to Cap P2P Uploads

[Mathew Brown]

[-- Attachment #1.1: Type: text/plain, Size: 1280 bytes --]

Hi,
  I'm new at traffic control and was reading up on HTB and using it to put an upper limit on traffic.  I have a 256k DSL with 64k upload (which translates to about 5/6KB uploads).  The machine running the P2P applications keeps filling up the 64K so my browsing from other machines in the network ends up being very slow.  Since there are several P2P applications, I wanted to set the entire upload cap to something like 3KB/s so it doesn't disrupt browsing.  However, I would also like to ssh and scp from this machine without having an upload cap.  The machine has a single interface to the network: eth0.  I tried the following tc lines but it appears to affect both the P2P traffic and my ssh traffic, resulting in a very slow ssh sessions:
  
tc qdisc add dev eth0 root handle 1: htb default 3
tc class add dev eth0 parent 1: classid 1:1 htb rate 102400kbps ceil 102400kbps
tc class add dev eth0 parent 1:1 classid 1:2 htb rate 102400kbps ceil 102400kbps
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 3kbps ceil 3kbps
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dport 22 0xffff flowid 1:2

Any ideas?  Thanks for your time.

Re: [LARTC] Simple Rule to Cap P2P Uploads

[Nikolay Kichukov]

Hi Mathew,
your adsl uplink is 64000 bps, correct?

102400kbps > 64kbps
3kbps != 3KB/sec

Another point, tc syntax is 102400kbit, not 102400kbps(as far as I
tested that).

3KB = 3*8 kbit

Test that and let us know if this helps.

Re: [LARTC] Simple Rule to Cap P2P Uploads

[Mathew Brown]

[-- Attachment #1.1: Type: text/plain, Size: 2978 bytes --]

Thanks for your reply Nikolay.  I feel my first post was somewhat unclear.  I hope the following information clears things up a little more:

1) The machine that I am trying to run do tc on has a single interface that connects it to the the rest of the network.

2) I sometimes have to ssh and scp files from that machine.

3) The machine runs various P2P applications.  I don't want the sum of their uploads to exceed 3 KB/s.

4) As you mentioned, my ADSL uplink is 64000 bps

5) The machine that I have tc running on and the machine with the P2P uploads are the same machine.

Thanks for your comments.  I'll try to check out the kbps vs. kbits.  But is the idea of what I'm trying to do now more clear?
