![]() ![]() Murus brings greater control over the OS X PF (Packet Filter) firewall without making you deal with the command line. I will include bandwidth management for Yosemite (and 10.OS X integrates a network firewall that can be configured via the shell Terminal and a more user-friendly application level firewall that can be handled via the System Preferences, yet has rather limited personalization options. Yes, actually Yosemite kernel INCLUDES IPFW □ they have just removed the shell frontend from sbin. Trick: you can copy the /sbin/ipfw binary from 10.9 to 10.10. On OSX 10.10 it works exactly the same way, you just have to use dnctl instead of ipfw to create pipes. Another good example of how pf/dummynet works is IceFloor on OSX 10.9. ![]() I’ve just noticed a weird thing: dnctl is in 10.9 source list ad, but it is not installed on OSX 10.9. A good source of examples is “man dnctl”. As of 10.10.3 you have to specify the “in” or “out” parameters for dummynet rules, otherwise you’ll get an error. On OSX dummynet rules must be placed in a special anchor defined as “dummynet-anchor” in your pf.conf. To see dummynet specific rules with pfctl you have to use the totally obscure and undocumented -d command like “pfctl -sd” to show dummynet rules. Author matt Posted on Categories technology Tags technology In the meantime, the intarwebs can help you find documentation for how to write rules for it. The man page for pf.conf doesn’t even contain the term ‘dummy’ but I expect that’ll come eventually. Hmmmm.ĭummynet is part of IPFW, so apparently rather than implementing ALTQ, Apple decided to modify PF to support dummynet. I downloaded it, set up a 256Kbps upload limit and I could once again let photos upload while I use my internet connection.īy what dark magic has Apple accomplished this task? Inspecting the network interface didn’t turn up anything special so I checked the firewall rules (sudo pfctl -sa) and found dummynet rules! In the PF ruleset! And increasing dummynet packet counters. Even better, a GUI interface for accomplishing my goal. So the PF firewall has no bandwidth shaping abilities. Or so I thought.Īfter a bit of hunting, I found the Network Link Conditioner within the Hardware IO Tools for Xcode. But Apple doesn’t provide ALTQ, the PF bandwidth shaper. ![]() I understand, as I too stopped using IPFW years ago in favor of PF. There’s a process named photolibraryd and it seems to have that same nasty behavior. The symptoms are identical but I can’t use IPFW because Apple removed it in OS X Yosemite. That IPFW solution worked just as well for throttling the other cloud music services.įast-forward a couple years to Mac OS 10.10.3 and the new Photos app that stores all my photos in the cloud. I blamed it on iTunes and used the built-in IPFW firewall to plumb a 256Kbps pipe so that iTunes Match uploads would stop erring out and I could use my internet connection during the long upload process. That should have made the upload process quick, except that something about the upload mechanism Apple uses caused severe network congestion and network stalls of 5 full seconds. The iTunes Match upload was far smaller because Apple has the worlds largest music library and iTunes Match only uploaded my songs that weren’t already already in their collection. For them to stream my music back to all my devices, I first had to first upload all my music (82 GB of data) to each service. A few years ago I sampled each of the “All My Music In the Cloud” services (iTunes Match, Amazon Cloud, Google Play). ![]()
