Most cable modem users have asymmetrical speed limits, like 1.5Mbs down, 100Kb up. Allowing separate speed limits for up- and down-stream would be really useful for things like throttling an upload to youtube.

Just installed the application, I clicked the security lock to enter my admin password and unlock preferences and enable me to edit the settings. I set my speed limit to 384k and then clicked the lock again to lock system preferences. Immediately upon clicking the lock, System Preferences crashes with the following error message in the stack trace:

Some times, an app use differents port and connect to differents host. It could resolve with the option to limit a specific app (all connections) without affect others apps (as littlesnitch).

Hi,

throttling appears to still be working fine, but the delay function is not - ie. there is no delay applied to the connection. confirmed still working on colleague's 10.6.5 machine. Happy to create a fix with a little guidance? Otherwise, hope an update will be possible in the future

Thanks

docker.picard.red’s server DNS address could not be found.

It would be useful to slow down internet speed of iOS devices connected using internet sharing. Currently Speed Limit does not effect the speed of that connection.

(tested using 10.7).

I recently get this error message
Failed to set speed limit

I'm using Yosemite.

I manually added my own speeds needed for a project, but I cannot figure out how to build this into an executable bundle.

What steps do I need to take to test my changes?

Hello,

I was wondering if anyone has forked this repository and attempted to add pfctl support for OSX 10.10+? Currently only ipfw is supported which has been deprecated since 10.10.

In 2014 this issue was created reporting the prefpane broken, but since then no real solutions have been provided. Network link conditioner has been mentioned as a replacement but doesn't provide the same features (can't throttle specific ports & not throttling 127.0.0.1).

Here's some resources that might be helpful:

• This blog post describes how to achieve throttling similar to ipfw by using pfctl.
• A quick search through this repo's code shows that ipfw is only called here: SpeedLimiter:40-45 and here SpeedLimiter:60.

Hi,

i love your tool for limiting speed, but it should have an input box, where you can set a custom speed.
I'd like to use the speed limit, to controle the download speed of for instance mac updates. If I download a 1 GB update, nobody else in my house can surf.

If the cutom input box is to hard to realise, can you add at least some more options of speed (up to 1MB or 2 MB per secound)?

Thank you

Injection worked - but didn't notice any difference... this would be really handy. any tipps?

It seems that the link http://mschrag.github.com is not working. Consequently can't download the binary.

Click the plus adds a port 1000, but I can't edit the port. If I double click on it it I can change the number, but something is preventing me from saving the number.
