Instructions on beefing up Apple's firewall

Hi all,
I read today some detailed instructions on how to improve the security offered by OS X's firewall...
...the problem is I stupidly didn't save the page as a bookmark or print it out, and i can't for the life of me remember where I read it...it may or may not have been in a post in one of the apple forums, or somewhere else! All I can remember is that it was fairly technical and required a lot of work in Terminal.
I don't suppose someone either knows what on earth I'm talking about, or of other such instructions they could point me to?
Cheers,
Nige

I can't point you to what you read, but I suspect it had to do with using ipfw. Put ipfw in the Search Discussions box and you will get a lot of hits.
Have a nice day.

Apple's Firewall opens the wrong ports!

This is a follow up question to a problem posted in another forum here. There are a couple of screenshots in the last post that illustrate the problem.
In System Preferences > Sharing > Firewall, checking Apple Remote Desktop opens TCP and UDP ports 3238. The problem is that Apple Remote Desktop needs ports 3283 (not 3238 - note the last two digits are transposed) and 5900. I've already worked around this issue by creating a new firewall entry that opens the correct ports, but I'd really like to get my Sharing Preferences corrected. Plus it bothers me that I can't block port 3238 by unchecking Apple Remote Desktop since that will prevent ARD from working, even though it opens the wrong ports.
This isn't really an Apple Remote Desktop problem, it's something wrong with the firewall in this system's version of OS X. Any idea how I can fix it, other than the ugly workaround I'm using, and short of reinstalling OS X?

Editing the .plist file is easy with xcode's Property List Editor, which I just installed. However, before I did that I simply copied a "correct" /Library/Preferences/com.apple.sharing.firewall.plist file from another computer. That was even easier

HT5559 I've followed the instructions to re-enable apple supplied Java SE 6 but this does not work. Java is still disabled and I'm having problems with dependant applications.

I've followed the instructions to re-enable apple supplied Java SE 6 following upgrade to version 7 which caused a number of applications to stop working.
I wondered if anyone has had any joy re-enabling JAVA SE 6. I've tried contacting Apple but cannot get any response. They've sent me back default messages claiming that they have tried to contact me - they haven't! I'd be grateful for some help with this. Thanks

This is the latest news about Java.

I do not use Java. So I cannot verify that this is the solution or not..
Best.

You have to change it using iTunes on your computer, as explained here: Change or remove your payment information from your iTunes Store account (Apple ID) - Apple Support. (This article: iCloud: View or change your iCloud payment information no longer works with iOS 8 or Yosemite.)

Apple Tv Firewall error.

I am running itunes 7.5.0.20 on a windows vista machine with ATV running via wireless connection through an Airport.
I am able to find the ATV and connect and start to upload items to it, but after a certain amount of time I get an error saying that itunes can not connect make sure your firewall will allow connections from port #. I can close itunes and start it back up, and it will work again for awhile, then I get the same error. I have to do this all the time.
I have uninstalled itunes and did a factory reset on the ATV, but it still happens.
This makes it impossible to stream. I am able to connect the ATV to my pc, and start the stream, but after 10-15 mins I lose the connection, and have to restart itunes.
Any idea's on how to fix this problem?
Thanks for your help & time.

If it works for a while and then stops it isn't a firewall problem. Next time it happens check the Apple TV and see if it lost its network connection. If it keeps dropping its network connection but you don't have any other problems with your network, the Apple TV may have a bad NIC.

Apple tv-firewall prolem?

In Leopard 10.5.1 Itunes sees the Apple Tv.
With the firewall on set to allow only essential services and Itunes added to appliocations attempting to sync a movie I'm told to make sure port 3689 needs to be opened, but no information other than that.
If I turn the firewall off I can sync the movie, but have been unable to stream one. I can get the "source" to appear on Apple Tv, but it dims after attempting to access it.
Seems odd!
Sharing is enabled and I have repaired permissions also.
Using Airport extreme

After installing 10.5.1 I had the same problem. I then decided to reinstall 10.5. without any additional software on my iMac and I resetted my AppleTV to factory settings. After doing this I could use my Apple TV with 10.5. but it still worked erratic somehow.
All the problems completely went away after I have changed the configuration of my Airport Extreme. Please try the following:
1. Open AirPort Utility, located in the Utilities folder inside the Applications on a Mac, or in
Start > All Programs > AirPort on a Windows computer.
2. Select your base station from the list, and then enter the base station password.
3. Click the Advanced button, and then click IPv6 Firewall
Deactivate “Allow Teredo tunnels” and “Allow incoming IPSec authentication”
4. Restart the Airport Extreme
Please let me know if it works for you.

What ports need to be opened from apple's firewall?

I googled that qmaster uses port 10012 tcp&udp, but what ports need to be open for Qadministrator and Batch Monitor?
They didn't seem to work just with 10012.
Is there any documents about this from apple?
Idea of just leaving firewall off sounds like Microsoft in te 90s'.
And even they have made an interactive firewall that asks you to open a port when some application tries to use it.
Well, these fcp applications are sooo PRO...

On the Qmaster system prefs pane, turn on the "Show Qmaster status in menu bar" option in the advanced tab.
Then click the Qmaster icon on the menu bar, and it will show you all active Qmaster services, and their TCP port. You would need that port open. You need to do this on every computer on the cluster.
In your setup, are all the computers on the same subnet? Although you may be on a large network, you can rope off your systems into their own sub network, with a master firewall and avoid this type of problem. Each computer will have a different port, and that port will change every single time you start and stop the service. The TCP port will fall between 40000 and 65536 (the highest port ranges).
So, again I recommend protecting the network which will protect all the systems universally. But try setting the TCP ports listed on all the service nodes, and remember that those will change whenever you start and stop the service. (I'm not sure if the port will change after a reboot as well.)
Good luck

My windows 7 cannot recognize my iPhone 5s. I followed all the instructions indicated in the apple website but nothing works.. It says "access denied" What should I do? Thank you so much.

I bought new phone last week and as I was trying to load music in it, my PC won't recognize it. It's not chraging either. I googled it then it led me to apple website then there's an instruction to follow there. I followed it all then after installing the USB driver it says "access denied" I don't know what to do anymore. Any help? Thank you so much.

Hi jenramayan,
Welcome to the Apple Support Communities!
At this point I would suggest completely uninstalling iTunes and all of its components in the correct order and installing iTunes fresh again from the apple website. Please use the following article as reference.
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
http://support.apple.com/kb/ht1923
1. Remove iTunes and related components from the Control Panel
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
I hope this helps,
-Joe

I am trying to restore my Apple TV. I followed the instructions in the article "Apple TV (2nd and 3rd generation): Restoring your Apple TV", but iTunes does not display devices. What do I need to do to see it?

I am trying to restore my Apple TV because when updating, it showed the USB cable point an arrow to the iTunes app icon. I call the apple support team and they said to connect the micro usb cable to my computer. But iTunes isn't showing the devices screen so I cannot do anything. Maybe it's the cable or something. Help.

Have you tried the following:
Disconnect the HDMI, power and USB cables
Wait for 10 seconds
Reconnect the USB cable
Immediately hold the menu and play buttons on the remote for 15 seconds
Apple TV 2 should now start flashing the LED wildly and appear in iTunes with the restore button.
If it still doesn’t show up, maybe it's your cable (even if it works just fine with other devices). Sometimes you need to wiggle the USB plug or put a little weight on it in order to have a reliable connection. Or just try another cable if you have one, sometimes that helps too.
If that still doesn't work, try the above but add the power cord after step 3 (and before step 4).
@Hecumi: this goes for your 2nd gen Apple TV as well, incl. the last tip concerning the power cord.
Hope this helps.

Manual, instructions, tutorials, anything on Apple site?

With the changes in Keynote 6.2 being so major, I thought I'd find a good manual to learn about how to use it. I'm not finding it. Where is this info? Thank you.

Connect the device to iTunes on your computer and unlock it from there

Firewall issues with Apple TV

Using Motorola SBG900 wireless modem, I can get Apple TV to work when disabling Firewall completely, but not with even the slightest firewall active. Following Apple's instructions here: http://support.apple.com/kb/HT2463?viewlocale=en_US I enabled the firewall ports that apple TV uses for both inbound and outbound traffic, but still I cannot use netflix, youtube, network time etc.
A lot of people seem to have the same issue. some, using my same modem as me has gotten things to work enabling the apple tv ports, but it's not working for me. What else could I try? is it ok to leave firewall turned off on the modem, if on my laptop I enable firewall in snowleopard? would this be enough to protect my computer?

are you talking about firewall on the computer or are you talking about router settings?
because if you mean computer firewall then it have no saying when it comes to atv accessing online services then it's 100% up to your routers settings
and if those are set correctly
I would look for a firmware update for the router

Police have instructed me to correspond with Apple in a burglary investigation

Hi,
Among other things taken in a recent burglary at my home was my iPad. The Police have instructed me to contact Apple and request that they inform me if someone attempts to register my iPad, so that they can then try to track how that user came into possession of it - and hopefully get a lead on the burglars.
I'm finding it difficult to find a point of contact to reach Apple to make this request. Has anyone any advice on how I can contact them?
Many thanks,
Joe

Instructions For Disassembling Apple 20-inch Cinema A1081

Anyone know where/how to find instructions for disassembling an Apple 20-inch Cinema A1081?
I'm very competent, and would like to swat out the LCD portion from a damaged frame to another healthier one.
Have searched everywhere for service manuals .... these older Apple Cinemas are getting harder to find.
Thank you ...

I have the same problem. Did your screen develop any further symptoms?
