I just wrote a simple script to cap my http and ftp server to 8KB/s
and I tried to cap the download speed of my clients.
I am using CBQ atm but I want to port it to HTB tomorrow.
My idea was to make a class that contains the max rate of my download speed - a few % (720, 768 would be max) and make that one bounded.
After that I wanted to make 'subclasses' for every client that has a rate of 512 and let it unbounded.
This way A client can download with a max of 720 by borrowing from other clients.
The Best way would be to let it equal around all clients (so that would be 'max-rate / number of clients' (thinking out loud helps  )
ok for this (without my latest idea) I have this:
| Code: |
tc qdisc add dev eth1 root handle 2:0 cbq bandwidth 100Mbit avpkt 1000 cell 8
tc class add dev eth1 parent 2:0 classid 2:1 cbq bandwidth 100Mbit rate 700Kbit weight 72Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded
tc class add dev eth1 parent 2:1 classid 2:5 cbq bandwidth 100Mbit rate 100Mbit weight 10Mbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000
tc class add dev eth1 parent 2:1 classid 2:12 cbq bandwidth 100Mbit rate 512Kbit weight 51.2Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000
tc class add dev eth1 parent 2:1 classid 2:13 cbq bandwidth 100Mbit rate 512Kbit weight 51.2Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000
tc class add dev eth1 parent 2:1 classid 2:14 cbq bandwidth 100Mbit rate 512Kbit weight 51.2Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000
tc class add dev eth1 parent 2:1 classid 2:15 cbq bandwidth 100Mbit rate 512Kbit weight 51.2Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000
tc qdisc add dev eth1 parent 2:5 handle 5555: sfq perturb 10
tc qdisc add dev eth1 parent 2:12 handle 6802: sfq perturb 10
tc qdisc add dev eth1 parent 2:13 handle 6803: sfq perturb 10
tc qdisc add dev eth1 parent 2:14 handle 6804: sfq perturb 10
tc qdisc add dev eth1 parent 2:15 handle 6805: sfq perturb 10
# filters
tc filter add dev eth1 parent 2:0 protocol ip prio 1 u32 match ip dst 192.168.0.2 match ip src 0.0.0.0/0 flowid 2:12
tc filter add dev eth1 parent 2:0 protocol ip prio 1 u32 match ip dst 192.168.0.3 match ip src 0.0.0.0/0 flowid 2:13

I did not test if allot because of the following problem (but it seems to work):
I have a nfs host on the box that does this traffic shaping and I listen to mp3s and watch movies through nfs but with this trafficshaping it is slowed.
so What I want is somehow filter out the NFS and give that the max speed (100mbits)
anyone that has a clue or some pointers for this problem or traffic shaping tips? (my only source for rtfm was the advanced routing howto) |

I guess you can do the most with tc filter, but to me it was much easier marking packets using iptables.
Look at this thread for ideas on how to do that: https://forums.gentoo.org/viewtopic.php?t=65244 |
