IPFW on Leopard / Tiger and AIRPORT CARD

Hi All,
I am creating a firewall rule using IPFW on my mac machine having an Airport card installed.
The rule is as below
ipfw add deny 802.11 from me to any 22
ipfw add deny 802.11 from me to any 80
ipfw add deny 802.11 from me to any 22 out
ipfw add deny 802.11 from me to any 80 out
But when i try to perform an SSH from another machine to this and vice-versa it works! Ideally it should not work....
However, if i replace the protocol "802.11" with "tcp". It blocks all the SSH option from and to my machine.....
My doubt is isn't Airport card belonging to 802.11n/g technology?
Please explain!!

Many Thanks for your help!!
reg,

If you want to block these ports on a per-interface basis then you need to specify 'via en1' for your AirPort card, IIRC:
ipfw add deny tcp from me to any 22 via en1
although why you want to block outgoing SSH is beyond me.

Mac Pro and Airport Cards

I've seen it written here about the new airport cards in the new Mac Pros. I was wondering if anyone might have called Apple about them. Are they user installable?

I called Apple tech support earlier today and asked them about it. They told me that I would have to take it to an Apple Authorized Service Center or Apple Store to have the new airport card installed. I figure, if I really needed it, I could do that so I cancelled my order and re-ordered without the airport card.
Hope This Helps.

Pismo and Airport card; Card not found

I just got an airport card for my Pismo. The computer cant see the card. What do I need to do to get it to work?
Specs:
PB Pismo G3
728mb Ram
OSX 10.4.11
Airport Card

I figured it out.
For those having the same problem, Make sure your card is installed correctly. The airport card DOES NOT go in the PCI card slot.
Read the correct instructions below.
1. Shut down your PB.
2. Pop open your keyboard.
3. Take off the heat shield.
4. You will see a small black wire just to the right of the PCI slot. This is your antenna.
5. Plug in the antenna to your card and slide the airport card ABOVE the PCI slot, with the serial numbers facing up.
6. Adjust the antenna wire to fit as you put the heat shield back on.
7. Power up and hit ok on the dialog screen saying airport card found.
8. Wait for wireless network to appear in your wireless network and then your ready to go.

Kernel Panic and Airport Card

My powerbook keeps giving me kernel panic messages. The culprit of this is a loose airport card (probably due to my computer being dropped). I took it into the Apple store yesterday and the guy said that my best bet was trying to stick a piece of plastic to hold the card in. I did this, and it still came loose and continued to give me the kernel panic. He said my only other option would be to buy a new computer. I find it hard to believe that there isn't a fix for this. Does anyone know if there is a fix for a loose airport card, or am I really out of luck like the Apple store guy said?

if reinstalling the card did not work, could be either loose or damaged card socket as cornelius mentioned.
you may want to consider taking it to service provider in your area who could open up the case to see exactly what is causing the problem: some loose screws/cables inside, damaged socket etc.
some service providers do not repair laptops though and send them to Apple anyways:
http://www.apple.com/buy/locator/service/
if it is just some loose connections inside, you may be charged for labour to fix it.
if the socket is damaged, it can be replaced as a separate part, as a guess it takes couple of hours labourparttaxes
and could be close to $300.
problem possibly could be caused by the bottom case, where the socket is connected on the inside.

G4 AGP Graphics and AirPort Card-not recognized

I have installed an AirPort card into my G4 (AGP Graphics) but the computer does not recognize that the card is installed. I bought this card on ebay and I need to know if my computer is to blame or if it is the card. How do I check this?

That is correct.
However if you have the hardware test CD that came with your G4, you might want to run the tests on it and see if it will provide you any further information on the status of the AirPort card.
A couple of other things to try:
Resetting the PRAM.
Resetting the open firmware. The procedure is
Start up into Open Firmware by pressing and holding the Command-Option-O-F key combination during startup.
At the Open Firmware prompt, type: reset-nvram
Press Return.
At the Open Firmware prompt, type: reset-all
Press Return.

Kernal Panic and "Airport card not installed"

Hello.
I opened my laptop's lid this morning to find that my airport card did not turn on automatically as it usually does. Nor would it turn on from the menu bar. So I decided to restart the machine. Upon restart and log in, Airport said that the card was not installed. Restarted again... kernal panic. Restarted a third time... another kernal panic. Then tried to safe boot, successfully booted and logged in. Restarted from the Apple Menu. Another kernal panic. Reset the PRAM and had a successful boot, but still have same airport not installed message.
Does anyone have an idea about what may be happening? Or any other ideas of what I can do. Anything would be of great help.
Thanks

Jason:
Your Airport Extreme card is either not securely installed or has failed and needs to be replaced. Remove the Airport Extreme Card, wipe the contacts and re-install, making sure that it is securely in place. Then restart and see if the card is recognized. If it is not, you need a new card.

B & W and Airport cards

Hi,
Is there a slot for an Airport card in the B&W?

No, the AirPort wireless system came along after the B&W G3s were discontinued. You can go wireless either by installing a compatible PCI card, a USB plug-in adapter (I'd install a USB PCI card to provide additional USB ports, since you only have 2), or a Wireless Ethernet Transceiver, like the Linksys WET-54G (requires no drivers, plugs into the ethernet port and converts it to a wireless signal).

Freezing in Leopard, Tiger and Panther

Hi, I'm pretty new to Macs, so excuse any of my possible ignorance. I searched in the forum, but could not find any topic specifically answering my question.
I have an old eMac (1.25 ghz, 768 mb ram) I purchased from a friend. Upon my first plug in, I decided to upgrade to Leopard 10.5.4 (He was running a previous version of Tiger). After installing it, I found that it kept freezing after start up. At first I thought that it was related to running too much stuff at once, until it crashed on the desktop with no applications running. This freezing occurs anywhere from a minute to almost an hour *if I'm lucky* after startup.
Anyway, I decided that maybe I should run a clean install on Leopard. After all, I didn't really care about any of the stuff on my friend's hard drive. But no. That didn't solve anything. I then proceeded to go to my disk utility and repair the disk and the permissions. THAT didn't solve it, either.
Finally I figured, "OK, maybe my version of Leopard is just corrupt". I did a clean install and reverted to Tiger. For about five minutes, I was happy...until it froze once again. So then I was like, "Screw it, I'll just try Panther". Nope. It seemed to freeze more and more the more I downgraded.
I'm using Leopard once again for a bit, simply because it seems to freeze the least there. I know this is the Tiger forum, but can anyone here help me with my problem? Please?!

Hello,
I have been having some freezing issues the past few weeks on my G5 tower. It happened after the last major update, even had a few kernel panics. I searched around the forums here and found the easiest fix for me which was running AppleJack http://www.boston.com/bigpicture/2008/07/beijing2008_preparationsthre.html
If you follow the instructions very closely you might get some relief. I ran it yesterday afternoon and so far, (keeping fingers crossed) no problems.
I know we have differing equipment, but AppleJack will work with many Mac OS X versions.
You have to completely shut down, then roboot holding down the 'command' and 's' keys after the first chime upon boot. When screen is up, then type in 'applejack auto restart' - it starts to clean up your system and checks and repairs disks. (will automatically restart computer after fixing all) Best to read all the directions before trying.
Good luck. Let us know if it works.
ps, i'm running Tiger, 10.4.11

Usage of Leopard, Tiger and olders versions

Hello,
For my study I'm searching for information of the usage of Leopard and older version of MAC OSX. Has anyone an idea?
I can't find anything usefull on google
Regards,

First that article was written a few years ago. The prices of external drives has dropped much since then.
The flaw in what the article purports is that when the internal drive crashes, usually everything is lost. Even a corrupt boot sector or partition table or even a bad install can turn the drive into a boat anchor. And backing it up would require a separate backup for each OS and each partition.
It might sound convenient, and it is, until the HD fails and then it's a disaster.
I have Tiger on an external drive which is very small and if I wish, I can take it with me. It also serves as storage for other data and for TM.
The general rule of not putting all your eggs in one basket certainly applies here.
What you plan will probably work, but it is not something I would ever recommend or do myself.
On my PCs, I used to partition my drive so I could run Windows and Linux. I had multiple partitions for the several parts of Linux that can exist in their own partitions. When harddrives became inexpensive I installed a second drive for Linux and unpartitioned my original drive for Windows only. It's not only simpler, it's much safer.
This is only my recommendation, and nothing else. Maybe we all have to do things like this once. Just be careful and remember you must be very careful not to ever crash any of the partitions.

About to buy Quad G5 - ? about RAM kits and Airport Card

Hi! I don't need it (current G5 dual 2ghz runs great), but boy do I want it!!
So, I am looking on MWarehouse and MConnection since they have $200 rebates on the G5. I called one of the stores mentioned above and they told me that I couldn't order the machine with the airport / blutooth card installed... that I would have to build through Apple. Huh? Strange! I forgot to ask if they sell it and I could install it (easy, I know). That would be silly of them not to sell it.
Ok... now RAM. So many choices. I think I want to throw in 4 extra GB's... that would be two 2GB RAM kits. I found such a variance in price, it makes me nervous. Will 2 of these kits suffice? ---
KINGSTON 2GB KIT FOR APPLE POWERMAC -- $265 each kit
MFG#: KTA-G5533/2G
(it says 2 modules... so they must be 1GB each?)
VS.
Kingston memory - 2 GB ( 2 x 1 GB ) - DDR -- $319 each kit
Memory - 2 GB ( 2 x 1 GB ) - DDR - 400 MHz / PC3200
MFG#: KTA-G5400/2G
(is this one better for the little extra?)
So, with either of these, I'd be using up 4 of the 8 slots, right? For a total of 4.5GB RAM.

i went through a similar 'ordeal' just before buying, thank god i read up a bit though, i've saved myself hundreds of dollars by not buying RAM and 2nd Hard Drive through apple, for the same price as 4GB i am able to get 8GB, and the exact same RAM as what apple use -- apple really overcharge in some areas!!
I decided to wait until i recieved the apple to see exactly what ram they use and try match it. i ordered 2GB from apple, otherwise i've had to have either 2x256MB sticks or 2x512mb sticks, and would have to go through the hassle of selling them on if i wanted the maximum 8GB (anything above 8GB obviously involves 2GB sticks, and you'll have a heart attack seeing the price for just one of them).
so i don't know about in the US, but the G5 i got here in the UK (assembled in Ireland) uses Samsung 4200 Ram, and i've been able to find the exact same ram on ebay and some websites, and at just under half the price apple sells them for. Otherwise from what i've read most people recommend Crucial, which is a bit more expensive, which is probably why apple don't use them!!
also the Airport issue, just do as you are doing and get it pre-built through apple, i thought it was just some PCI card or something, but it's actually a pretty nifty looking grey strip (antennae) on the back, and there seems to be some wiring that goes behind and underneath the main CPU housing.. i'm sure it wouldn't be too tricky a job for someone to self install, but i myself wouldn't have liked to try, when apple do it for little extra

I have purchased a Imac G5 20" Computer. I does not have wireless, so I purchased and airport card to install. after opening the computer, there is no metal stand to install the card. i ordered a stand on Ebay. Do I need to buy an antenna too?

Any help or suggestions are greatly appreciated.
I am a first time Apple user and first time Support Community user.
If anyone has any other upgrade suggestions or something you would do to this unit, please let me know.
Mainly bought it to interface with an iPad down the road, but i need wireless internet.
The ethernet cable works fine but not in area where I want the computer.
Thanks !!!

Yes, you will need an antenna as well. You will probably want to add more memory, you can have up to 2GB (an iSight can take 2.5GB), and depending on the size of the drive, you might want to put a bigger one in as well.

Airport Card Not Recognized after Leopard Install

After the Leopard install the airport card on my Dual 1.8 G5 is not being recognized (the airport menu reads "no aiport card installed". Of course there is a card and when booting a from Tiger there is no problem. It's a stock apple airport card. Any suggestions?

Interesting update...
After reading several other threads of semi-related topics, I decided that there's no harm in reinstalling the software. After placing in the disk and restarting you get the WELCOME splash screen. On the menu bar, you can choose to view the System Profiler prior to installation. My Airport Card did how up here - telling me that it's not a hardware issue. I'm in the process of re-installing 10.5 - which will take 1-2 hours to complete. I'll let you know how it works out.

Airport card(s) for Power PC G5 and Powerbook G4

I would like to set up an Airport base station to connect my Power PC G5 (dual 2 ghz with 5GB of SDRAM and OS 10.5.8) and my PowerBook G4 (550 Mhz, 512 MB SDRAM and OS 10.4.6). Can someone tell me what combination of base station (Airport Extreme?) and Airport cards would be appropriate for this setup and recommend a supplier, since I suspect cards may be hard to find for these older computers?

I would just add that either card - Airport/Airport extreme will work with any base that supports the 802.11 a/b/g and now n standard - basically all. You can buy an n with an eye toward future upgrades but I use an a/b/g Airport Extreme, several years old that I'm happy with. So, you can look at saving money and getting a generation obsolete if it's just for home. To put it into perspective, the a/b standards were 8 or 9 Mb transfer rate, IIRC, and the g brought it to 54 Mb. Consider the size of network and the size of your ISP "pipe" (ISP data rate) you have.
As far as Airport cards are concerned, the earlier poster is correct. I would just add that there are physical differences between Airport and Airport Extreme cards so they indeed are not interchangeable. The Airport - Powerbook g4 500/550, etc. - uses a card with an end connector, that is, a plastic socket perpendicular to the card which mates to an adapter bracket in the computer. The Airport extreme has an edge connector ("pin" lands right on the edge of the card) which slides right into a socket on the board. Your generation of powerbook would likely use the former (I have a pb g4 500MHz titanium which uses Airport; my pb g4 1.67 GHz uses Extreme).
Go to System Profiler/network/airport and that will tell you if you have a card installed and which one.

Can't set up my airport card to share my internet connection with notebook

I have an iMac with an airport card -- I have a visitor with a notebook and I cannot set up a way to share the ethernet cable connection through my computer and airport card. No matter what I do it the Airport will always show "AirPort 5 has a self-assigned IP address and may not be able to connect to the Internet". I don't understand why it has a self-assigned IP -- I thought by using the internet sharing set-up that it simply duplicated a sharing of the modem through the built-in ethernet and using the same IP address. What am I doing wrong or is it just not possible to do it due to what my airport card allows? I am doing everything by the letter according to the instructions iMac G5 although I upgraded to Leopard operating system. Any advice? i do have an airport express but I can't understand why the airport card simply does not share my IP address.

The Airport Utility will only see (scan) the router if your PC is connected to it.
You may do the following.
1) Hard reset using the reset button on the router while plugged in. Keep pressed the button for 5 seconds to reset.
2) Connect to "Apple ..." network as shown in "View available wireless networks". Don't worry if you lose you connection to your existing matter. Your PC has already been setup to connect to your existing network and it takes only a click to connect to it. After you're done with Airport Express, your PC will automatically connect.
3) If still not successful, try opening network connection properties. Go to control panel, right click Network connections and select properties. Go to Wireless tab on the top and check if apple network is listed in your preferred networks. If not, try steps 1 and 2 until you find the network here. If it is listed here, open its properties and change encryption to "Disabled".
4) At this point, you should see it in Airport Utility.
