*SOLVED* Newbie questions about traffic throttling and control panel [message #6526]

I'm looking for a way to limit the VPS's to 1Mbit/second. I saw http://www.serverpowered.com/openvz-bandwidth-accounting.php but it has broken links all over it so I don't think it's supported anymore.

I'm also looking for a control panel for the end user to be able to re-install, reboot, stop, start, etc.

If you can help me out on any of these that'd be great!

Thanks.

Hello,

You can limit traffic of VE using tc. For details look at
http://wiki.openvz.org/Traffic_shaping_with_tc article.

As concerns panels. I've remember some topics here on forum from persons who had created their own control panels. You can use search to find this posts and modify presented panels for your needs. For example search gave me the following link:

Hi there,

So I tried to use tc and I get this error when running the command;
DEV=eth0
tc qdisc del dev $DEV root
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 100mbit
tc class add dev $DEV parent 1: classid 1:1 cbq rate 256kbit allot 1500 prio 5 bounded isolated
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip src 10.0.15.101 flowid 1:1
tc qdisc add dev $DEV parent 1:1 sfq perturb 10

Error:

RTNETLINK answers: No such file or directory
Unknown qdisc "cbq", hence option "avpkt" is unparsable
Error: Qdisc "cbq" is classless.
Unknown filter "u32", hence option "match" is unparsable
Unknown qdisc "sfq", hence option "perturb" is unparsable

I suspect, that you didn't load appropriate kernel modules. For example, in order to use CBQ qdisc you should load sch_cbq qdisc:

[HN]# modprobe sch_cbq
[HN]# tc qdisc add dev eth0 root handle 1: cbq avpkt 1000 bandwidth [HN]# tc qdisc show
qdisc cbq 1: dev eth0 rate 100000Kbit (bounded,isolated) prio no-transmit

HTH,
vass.

[root@vz101 ~]# tc qdisc add dev eth0 root handle 1: cbq avpkt 1000 bandwidth [HN]# tc qdisc show
                                                                              ^^^^^^^^^^^^^^^^^^^^ 
                                                                        This is a scrap from other command
Should be so:
[HN]# tc qdisc del dev eth0 root
[HN]# tc qdisc add dev eth0 root handle 1: cbq avpkt 1000 bandwidth 100mbit

Hmmm... for me, if required modules are loaded, it works?

Can you provide me an access to your node?

Thanks.

During PMing, we investigate, that the problem seems to be in tc in CentOS 4.4. Attached patch solves the problem.

Hi!
Don't panic! Smile

I've never applied a diff either..but will shortly...if I must. Basically...this is what must happen:

1) Download diff
2) Download source code to tc
3) Apply diff to source code
4) Compile tc from the modified source

It's not as difficult as you might think..but there can be problems. I'll report back later with more.
