[Mac OSX 10.4] How to firewall an app?

[mattemuse]

I was wondering if any of you gents know how to firewall a specific application in OSX 10.4 - either with the built-in IPFW firewall, or otherwise.

A for effort, but you’ve linked to information which is specific to OSX 10.5, whereas I’m hoping some knowledgeable chap can direct me towards instructions for OSX 10.4.

In your system preferences, just search for Firewall Advanced Settings

Then Add what programs with the +/- buttons. It should pop up Finder, and direct you to all of your apps automatically.

Hope this helps!

…would screenshot, but I use 10.6 hehe…

edit
Here you go. I hope this is what you’re looking for.

Apple doesn’t support old products. Enjoy using shitty obsolete apple software.

Drew++ thanks for your reply, however it only works like that in 10.5 and up. 10.4 doesn’t have any easily accessible per-application firewall. I know how to turn on the firewall already, i just want to make sure one specific program can not send or recieve data.

sersoft, thats considered trolling which is apparently a bannable offense around these parts, but I just felt like letting you know that I do enjoy apple software, and their support or non-support isn’t the issue - just my own lack of knowledge about how to use the software.

[sersoft]

Just letting you know that apple doesn’t support old shitty software, I wasn’t implying that apple itself is shitty, your brain just assumed that because you probably hate apple deep inside.

Did you try turning off the internet while you’re using the program?

Yes. I’d prefer not to. The handy thing about firewalls is that they can be configured to block specific programs. Therefore I’m posting on internet forums to find out how to do this.

If you know/could find somewhere which port(s) the program in question uses, you can use ipfw which hopefully is still included in 10.4

man ipfw

or

add rule_number deny tcp from any to any port_number out

(replace rule_number and port_number with their values)

What app are you trying to firewall?

I found this on the net for blocking LimeWire… I figure it should work for something else.

To open the OS X Firewall for Gnutella access, please do the following:

1. Open up ‘System Preferences’
2. In ‘Internet & Network’, open ‘Sharing’.
3. Select the ‘Firewall’ tab (your Firewall should be on)
4. Select ‘New…’
5. From the ‘Port Name’ drop down box, select ‘Gnutella/LimeWire’
6. Select ‘OK’
7. Restart your LimeWire application.

For Mac OS 10.4 Tiger users, you’ll see the firewall option for new setting is a little different to previous OSX versions. Here you’ll need to add the port numbers also for both TCP & UDP instead of a single port option. The default port LimeWire uses is port 6346. Whichever port you connect through for LimeWire will need to be reflected here.

• Sample Tiger Firewall instructions below for Tiger users:

1. Select firewall tab, 2. Select new, 3. Select Other, 4. Type in port number & Gnutella/Limewire, 5. Make sure this setting is ticked so it’s allowed through the firewall. You may need to scroll down to the bottom of the list to find the setting.

BTW the advanced settings of Stealth mode & Block UDP Traffic does not affect LimeWire’s incoming requests.

[mattemuse]

Hm, so it looks like I either need to find out what port numbers need to be blocked, or acquire a firewall which can block specific programs.

[Azrael]

Yep. Unfortunately, per-app blocking wasn’t introduced until Leopard (only per-port in Tiger). I know a lot of people swear by Little Snitch – you’ll probably want to double-check that it can do what you want to do, since it isn’t free (but the trial is).

thanks for the info, this looks like it.

edit - no seriously, you’re a hero, man.

I prefer use ProteMac NetMine.It’s really good firewall.It’s must be helpful to everyone
