You can do so by using the -l option as follows (the output is pretty ugly and needs to be parsed better): usr/libexec/ApplicationFirewall/socketfilterfw -add /Applications/MyApp.app/Contents/MacOS/myapp Once signed, trust the application using the вЂ“add option:

usr/libexec/ApplicationFirewall/socketfilterfw -v /Applications/MyApp.app/Contents/MacOS/myapp usr/libexec/ApplicationFirewall/socketfilterfw -s /Applications/MyApp.app/Contents/MacOS/myapp If you are enabling the firewall using a script, first sign your applications that need to allow sharing but are not in the TRUSTEDAPPS section by using the -s option along with the application binary (not the. There is also a list of TRUSTEDAPPS, which will initially be populated by Apple tools with sharing capabilities (e.g. This shows the number of exceptions, explicitly allowed apps and signed exceptions as well as process names and allowed app statuses. usr/libexec/ApplicationFirewall/socketfilterfw вЂ“getappblockedВ /Applications/MyApp.app/Contents/MacOS/myapp usr/libexec/ApplicationFirewall/socketfilterfw -listapps The вЂ“listapps option shows the status of each filtered application: usr/libexec/ApplicationFirewall/socketfilterfw -getallowsigned usr/libexec/ApplicationFirewall/socketfilterfw -setallowsigned on Therefore, traffic can be allowed per signed binary. While it would be nice to think that that was going to be everything for everyone, it just so happens that some environments actually need to allow traffic. usr/libexec/ApplicationFirewall/socketfilterfw -setglobalstate on

usr/libexec/ApplicationFirewall/socketfilterfw -setloggingopt: detail For example, if you need to troubleshoot some issues, you might set the logging to detail using the following command: You can also control the verbosity of logs, using throttled, brief or detail. usr/libexec/ApplicationFirewall/socketfilterfw -getstealthmode usr/libexec/ApplicationFirewall/socketfilterfw -setstealthmode on

The output would be as follows, if successful:ДЇirewall is set to block all non-essential incoming connectionsДЄ couple of global options that can be set. usr/libexec/ApplicationFirewall/socketfilterfw -getblockall usr/libexec/ApplicationFirewall/socketfilterfw -setblockall on To configure the firewall to block all incoming traffic: In /usr/libexec/ApplicationFirewall is the Firewall command, the binary of the actual application layer firewall and socketfilterfw, which configures the firewall. To debug, use the following command: вЂњ/usr/libexec/ApplicationFirewall/socketfilterfw -dвЂќ.If a remote system, do wait and then enable the first time to make sure everything works before enabling the firewall for good. Configure global settings, then per-application settings, then enable the firewall.Whatever you do, you can always reset things back to defaults by removing the file from /Library/Preferences replacing it with the default plist from /usr/libexec/ApplicationFirewall/.Configure the firewall fully before turning it on (especially if youвЂ™re doing so through something like Casper, FileWave, Munki, or Absolute Manage where you might kick yourself out of your session otherwise).

Some tricks IвЂ™ve picked up with the Mac Firewall/alf scripting: However, now there are much more helpful and functional options in socketfilterfw that will allow you to more easily script the firewall. And you will still use socketfilterfw there for much of the heavy lifting. The tools to automate OS X firewall events from the command line are still stored in /usr/libexec/ApplicationFirewall.
