IPFW / PF port throttling help

[scottfreeman]

Hey guys.

I use Skype to keep in touch with my fiancee, but since I'm on a fast connection Skype sends HD video which uses 130%+ of CPU causing all the fans to run at full speed. Running at this temperature all day isn't a good thing!

I used to use IPFW to throttle the port I set Skype to run on. The script looks like this:

sudo ipfw pipe 1 config bw 20KByte/s
sudo ipfw add 1 pipe 1 src-port 5555

IPFW has been removed in 10.10 Yosemite so this no longer works. I know I can use PF to do the same thing, but I can't figure out how. I've downloaded IceFloor and I believe I set it up correctly but it doesn't seem to be working.

Can anyone offer assistance? I want to throttle port 5555 to 20KB/s.

Here's hoping.... Thanks!

Not sure what the rules on bumping are, but it's been a while without a reply. This is still a pretty major issue for me and I'm still unable to figure out how to throttle my ports using PF.

Here's hoping someone can help....

1: Google -- "ipfw osx"
2: First result -- https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man8/ipfw.8.html
3: Quick visual scan -- "This utility is DEPRECATED. Please use pfctl(8) instead."

So I would probably try using pfctl.
