How I can limit Download/Upload bandwidth for:

  • Entire OS.
  • One network interface.
  • Single application.

Although this is an old question, I came across this when looking for an answer to the same question. The OS and interface limits are already addressed in an earlier answer, so here is a way to set up application specific limits. Use an application called trickle. So do sudo apt-get install trickle. You can limit upload/download for a specific app by running

trickle -u (upload limit in KB/s) -d (download limit in KB/s) application

This will launch the application with the specified limits. You can also specify "smoothing" time, so that trickle samples over the desired time period in case your application has bursts of bandwidth consumption and you'd like the bursts to be allowed so long as the average is within your specifications.

    Thank you very much! This solution is perfect for controlling bandwidth on a per-application basis. Please don't ever hesitate to post an answer, even if the question is years old. For future reference: You might be presented with an error message like trickle: Could not reach trickled, working independently: No such file or directory. You can remove this warning by executing trickle in standalone mode with trickle -s. Mar 17, 2013 at 23:38

    Trickle will run the application for you with the limits being enforced. So all you have to do is restart the application without using the trickle command.

    Exactly what I needed, when trying to simulate a slow network connection.

    Note that this only works when your app is using gLIBC syscalls for networking. If you app is written in Go for example, it is not using gLIBC syscalls and trickle won't work on it.

Limiting single interface is easy, but global rate limits need more complex rules as do application based rules. I'm not saying that it can't be done, but it requires quite a bit digging in to the internals of the networking.

Here is a quick How to on setting up a per interface limit

If you really want to set up application based rules, you should look in to some firewall framework, like shorewall, which have helper features to configure shaping. Even with these tools, it requires quite bit of forethought and testing to get it in to place. Doing something like this ad-hoc is not yet quite that easy.

  • wondershaper isn't working I don't know why (even wondershaper eth0 1000 1000 has no internet bandwidth. I need to limit all of the eth0 bandwidth not only specific applications. how can in do that?

If you want to limit bandwidth for a specific IP address, you can use this:

tc qdisc add dev eth1 root handle 1: htb default 12
tc class add dev eth1 parent 1: classid 1:10 htb rate 2500kbps
tc class add dev eth1 parent 1: classid 1:11 htb rate 2500kbps
tc class add dev eth1 parent 1: classid 1:12 htb rate 5000kbps

tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst flowid 1:10
tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip dst flowid 1:11

    that was pretty convoluted. A few #comments would go a long way. You could for instance add links or explanations for qdiscs, classids, htb, etc.

  • So, by default, the above limits everything to 5000 kbps unless filtered into some other queue? What about if we don't want to limit everything?
