My B/W G3 (10.2.3) has DSL hooked up to the built-in enet. I have a PCI NIC installed (D-Link 530tx+, which works flawlessly, BTW). I'm internet sharing to my iBook on the NIC (no AirPort anywhere, just hard enet cat 5).

For some reason, starting a couple of days ago, the iBook refuses to see the internet. It sees my B/W on the network, but cannot seem to get the internet traffic routed through to the NIC properly.

I have the G3 NIC on a manual IP address (192.168.xx.xx1) and the iBook set for a manual IP address (192.168.xxx.xx2). This was working perfectly, and then, for some reason, stopped working.

I've trashed the network settings and rebuilt them on both computers to no avail. I've restarted internet sharing (Apple's prefpane) time and time again, but nothing seems to work.

Can anybody help me here? I don't even know what other info might help here.

Augghhhh!!!!!

Have you rebooted the G3 since you started to have the problem? It could be that something's gone wierd with the internet sharing software and a reboot could fix it.

This sort of really wierd interaction/problem/pain in the ... is why I have a hardware router to share my connection; if it ain't sharin', then it's the router. If one computer works and another doesn't, it's a problem with the computer that doesn't work.

Anyway, try a good "turn it all the way off and let it sit for a while" reboot of the B/W and see if that fixes your problem.

I have rebooted, in fact. However, nothing has changed.

The wierd thing about this is that it had been working *perfectly* for several months. All of a sudden... >bam< it stops.

I still can't figure it out. Still working on it though.

Anyone? Help a user out here! (Sorry for the frustration... it's been a long week hashing this one out.)

What else have you done, particularly with the iBook's configuration. This sounds like one of those situations where dumping the networking on the computer completely and starting over might help, but obviously you've done that.

Also, how is your internet sharing configured? Is there a possibility that something there got changed without your doing it? (Stranger stuff happens-people use Windows!)

Finally (should have asked this the first time I replied) can you share files between the two computers? And have you tried (ohmigawd, why didn't I ask this the first time) REPLACING THE CABLES? That's always the first thing to think about. If the dog tripped on a cable and your spouce/roomie/maid/total stranger put the cable back where it had been, the cable could have been damaged without your knowledge. A marginal cable could have just given up. The cable your buddy built for you could demonstrate just how many beers he'd had before he got to the last connector. Lots of things could have happened to cables, so try replacing them, starting with the one between the iBook and the B/W.

Sounds like it might be a DNS problem. See if the iBook can connect to http://64.58.76.227

If it can, but can't connect to http://www.yahoo.com, you know you have a DNS problem, and specifically, that the DNS IP numbers in your iBook's TCP/IP control panel are no longer right. Find out from your ISP what the proper DNS numbers are.

jwblase · Jan 14, 2003, 12:08 PM

I checked, and I'm using the proper earthlink.net DNS numbers (all three of them in the proper order). The wierd thing is that lookups seem to work *some* of the time.

I can connect to yahoo.com, but the whole page doesn't load. (Images and other things take a dog's age to load, while other images load right away... even after I purge the disk and memory caches!)

This is getting stranger and stranger for me... The B/W is still running strong (with no wierd hacks or anything), but the iBook is still not running right.

I just thought... is this a 10.2.3 or Rendevouz issue?

Sorry it wasn't cables-though it still could be! Anyway, what Mac OS version are you running on the iBook? There could also be a problem with the settings for Internet Explorer-I'd compare the settings on the iBook with those on the B/W. If there's a difference, that could be your problem.

Once again, can you consistently share files between the two computers? That'll say a lot about the network capabilities of the iBook.

Oops. Double post.

If you are using Safari (Apple's new web browser, note: the latest update of Safari v51 fixes this issue) it does something to the linking of the tmp folder and that messes up a lot of things. If you are not using Safari then i do not know the problem but just try out this solution. This fixed all my networking problems right away. Just open up terminal and fire away:

ln -s /private/tmp /tmp

you do not need to restart or logout and login again it just works!!!!!!!!!!!

John Strung · Jan 15, 2003, 07:09 PM

I presume you have the earthlink DNS numbers on separate lines in the Name Server Addr. box with the Primary on top and the secondary below. Try switching them so the secondary is on top. This often fixes problems which are caused by an overloaded primary DNS.

Again, to check to see if DNS is indeed the problem, see if you can connect quickly to an IP number like I posted in my earlier post.

jwblase · Jan 15, 2003, 09:41 PM

The DNS numbers are correct. I can connect, but not quickly. Again, I'm wondering if this is a NATD problem within 10.2.3??? If so, is there a way to completely reset the NATD prefs? I don't know what they're called.

Did you try switching the order of the three servers as I suggested above? Did it make any difference?
