Internet Sharing under 10.2: how?

elcapitan · 09-03-2002, 08:19 AM

I've read the thread "internet Sharing solved", but it hasn't helped answer this basic question: how do you set up the client machine to use the route through the 'host' machine successfully? And is there anything that needs to be done on the 'host' machine besides turning on Internet Connection Sharing?

I had this working successfully under 10.1.5 using IPNetShareX, but under the 'proper' 10.2 scheme, there seems to be no equivalent actions to setting up the private subnet addressing.

G4/450; 640Mb, 2IDE hard disks, Internet connection through cable modem, airport card.
TiBook 667 MHz, 512Mb, airport card

Thanks for any help you can give me.

The big trick is that you must turn off the Jaguar built-in firewall on the host machine. This is not good! I also used to use Brickhouse and IPNetShare on 10.1.x and never needed to disable Brickhouse. (In fact, I may re-install it and see if I can leave that on...) You can add an exception to the Jag firewall and enable Port 80 or web sharing, but you'll be blocked from all other services - checking mail, signing in on Apple's tech boards, etc. A few more tricks - edit the network settings on both machines so that your main internet connection (ethernet, for example) is the first (default) port on the host machine and airport is the first (default) port on the client computer. Set the client computer computer to DHCP, and it'll just pick up the router and subnet addresses. (Use encryption and a password for your network!) Just for good luck, I put the DNS and Search Domains values in the Network settings of the second machine.I know that this was necessary with the old setup; I'm not positive that it's needed now. Also, don't let the host computer go into complete sleep, or you'll lose the connection. Good luck. Post back if there are any problems, but this did it for me.

Thanks Russ for the insight. I too had success with IPNetshareX (haven't tried Brickhouse), but at the moment I have all the various things you mentioned adjusted correctly but it still only works with IPNetshareX on!

However I cannot access my 10.2 firewall (it is all greyed out) as some remnants of Nortons Personal Firewall that I attempted to remove have stayed deep within the system and have made "Jaguar firewall unavailable" - this may be the root cause of my connection sharing problem using 10.2 option.

Do you still suggest setting the computer to DHCP even with a dial up connection? I was using all the manual setting as per under IPNetshareX (i.e. My Network settings are – Host (iMac)– 192.168.0.1, 255.255.255.0 – Client (iBook) 192.168.0.3, 255.255.255.0, 192.168.0.1).

I was wanting to buy a couple of airport cards and allow my kids to use their iMac in their study area hooked up to the host machine, but I am not inclined to make the purchase until I can get this working with my iBook which is sitting alongside the host machine, connected via ethernet.

Thanks for the earlier advice - I'll keep plugging away - mabe need to find someone that can advise on what needs to be removed of the Nortons product to give me access to the jaguar firewall again

Sorry, zambo, I really wish that I could give you the exact answer for your problems. It seems that you have elements of Norton Firewall and IPNetShare X still in your System. That's seems to be mucking up everything else. (I did a complete erase and install, so I never faced that problem.) Is there some sort of "Restore Default Settings" in IPNS X? If there is, use it and trash IPNS X. Just use the Internet Sharing in OS X. if you use that, yes, set the client machine to DHCP. If it 'sees' the internet sharing signal, it will automatically pick up the router and subnet addresses. (In fact, the name of your network scrolls by briefly by the Airport icon in the toolbar when connecting!) Good luck.

elcapitan · 09-07-2002, 10:46 AM

Just an update.

After searching the "normal places" (MacNN forums and OSXFAQ had the most info). I got Internet Sharing working.

I had read that you had to manually set the IP address of the "base station" (my G4/450) to 10.x.x.x. I did that; it worked, but then I found it wasn't necessary. I tried again with the G4/450 set to Manual, IP=0.0.0.0, and it still worked. The TiBook was set to DHCP and was automatically given an IP of 10.0.2.2 by the G4/450.
I also found that I did not need to give the TiBook the DNS addresses of my ISP, so that means the G4/450 was dealing with (or just passing on) name look-ups.
Next bit of good news (rock on, Rendezvous!) was that both my inkjet and laser printer on the G4 were available in the print command on the Powerbook.

In fact, the only thing I'm unhappy about is that (as Russ R says) I had to turn off the G4 firewall in order for the TiBook to access the 'Net. That seems a bit drastic! Has Apple not implemented the more sophisticated approach of different firewall settings on different ports?

Thanks for your help.

Well, kind of. You can turn on web sharing or enable port 80, as pointed out in this Mac OS X Hint . Then, you can surf the net, but you won't be able to check mail or do a lot of other things. What Apple's firewall does not do is block all incoming and allow all outgoing communication. If I have time over the next few days, I'll re-install Brickhouse (which did have that option), and I'll post back. Also, you are right - the DNS Servers and the Search Domains are no longer needed on the client machine.

zambo · 09-08-2002, 06:41 PM

Thanks for all the tips Russ - I finally got the airport cards and the computer-to-computer thing to work. File sharing is a happening thing now (though the connection comes and goes sometimes) though the sharing an internet connection bit still has it's moment, though I did get it to work finally.

I followed all your advice and set my host to 10.0.2.1 and just leave it there which is good for sharing either via ethernet or airport. The airport enabled client machine I had working at DHCP for internet sharing and it self assigns an IP address when it's not net sharing that works fine for file sharing locally.

My internet signal drops occasionally out (a problem I don't normally have when the dial up is plugged straight into a single machine) - I was wondering whether when net sharing whether there are signals (from my c2c network) that get sent that may cause confusion to the ISP provided signal ...? Though I had read somewhere that in having DHCP enabled can be recognised by some ISP's who have a disconnect policy - have you heard of that?

I wonder if the ability to check email will be an upcoming feature we can access (via a 10.2 upgrade), or is the way 10.2's firewall is written, makes it too difficult - I would be very interested in your outcome on Brickhouse experiment.

Thanks again

Surprisingly, you don't need to set up a separate computer-to-computer network to share files. I just had Internet Sharing and File Sharing on the host computer turned on, and I was able to connect to it with the client computer.

One more observation: In earlier versions of OS X, when you connected to a computer as a registered user to do file sharing, you were able to access all other's users folders.This is fixed in 10.2. Now, you can only get to your folders and the Shared folder.

elcapitan · 09-08-2002, 10:08 PM

And if you have Appletalk switched on in both machines for the C-to-C network, Finder's "Connect to Server" find's the machine and gives you it's network name. But with Appletalk switched off (or in use through another port on one or both machines) you have to type in the IP address of the machine you want to connect to (at least, that was my experience). After that, it all works fine.

Russ R. · 09-08-2002, 10:54 PM

Yeah, I typed in the IP address of the client machine, also. But, isn't this what Rendezvous is for? Isn't that just supposed to pick up the IP of the networked machine? Or, am I missing something?

If so, you're not alone.

My connection situation: I have a ADSL line and dual ethernet cards. I have a single box behind the gateway. To configure this this to work for me I had to be rid of any other NAT and firewall software - for me this meant brickhouse. To enable sharing I configured my LAN ethernet card as follows.

HOST:
Configure - Manually
IP - 192.168.1.2
Subnet Mask - 255.255.255.0
Router - 192.168.1.1
DNS - my ISP's dns servers

CLIENT:

Configure - Manually
IP - 192.168.1.3
Subnet Mask - 255.255.255.0
Router - 192.168.1.1
DNS - my ISP's dns servers

Then I turned on sharing. If you can access your firewall you will need to configure the protocols your client system needs to access one by one.

Hope this helps and your mileage may vary.

Though I thought I had it right, I can't repeat a shared internet connection between my two iMac's using airport cards.

I have followed all the tips, but Explorer just can't find the server when it tries to open my home page.

I have the host set to airport, 10.0.2.1, 255.255, etc. I have Appletalk on and make sure that the firewall is off. I set internet sharing to on and click the airport check box.

Client is set to airport, DHCP, 255.255 etc, Appletalk on and firewall off. Have missed anything?

Some related observations which I am wondering are unique to me.

On my host, sometimes email returns a "can't connect with server" message if airport c-to-c is up. Similarly, Explorer won't generally launch with airport turned on. Both work flawlessly when I hit the Airport Off option in the menu bar.

I did a clean install of 10.2 and Classic to both machines last weekend in order to make sure that the new system and airport cards would operate in as "clean" a system environment as possible - so I am at a bit of a loss with my lack of success with net sharing.

File sharing works flawlessly.

Off thread, but being from the Land of the Large Shrimp, I pray that Apple will someday make software that has better date setting options - I downloaded iCal today and found it's dates are set for U.S. format with no obvious preference option to alter.

Anyway, any suggestions on 10.2 sharing still most appreciated.

Cheers

Russ R. · 09-11-2002, 05:46 PM

Personally, I did not set any numbers *at all* into the Airport network settings on the host or client machines. The only thing that I set in the Network prefs for Airport was DHCP.

zambo · 09-11-2002, 06:16 PM

Thanks for the tip - I'll try it out. Ironically, whilst I was downloading my email which had your most recent response to the thread in it, I turned on internet sharing on my iBook which I had connected via ethernet to my normal host machine - an iMac. As I was checking email thru my iBook it became the host obviously. I hit a couple of buttons to configure the relationship and booted a web page up on the iMac immediately - go figure!

Will try this with airport between the iMac's later today - thanks again.

zambo · 09-11-2002, 08:35 PM

After getting a web page up thru sharing my internet connection from my iBook to my iMac (called #1 using DHCP) (via ethernet) I thought I'd be brave and connect to the downstairs iMac (called #2 also using DHCP) via airport and see what happens (I hit the share the internet option on #1 to flick on the connection to #2 which remember originates at iBook). Well the airport worked a dream and I got internet sharing happening strong and clear.

Now as a follow up test, I disconnected the ISP, re-dialed up thru #1 (manual connection not DHCP this time) and left #2 as it was prior - hit the "share connection using airport" on #1 and couldn't raise a thing on #2 in regards to a web page!

I feel that in the end sone rather simple thing is out, but I have tried a large number of pemutations, but still not there - interesting that I can get internet sharing going either on ethernet and over airport but not in the exact manner I'e like.

The journey continues ...
