Mac Forum / Country Specific / UK Mac Group / October 2008Network problems after Security Update 2008-007
Hi all I'mhoping someone can help me sort out the networking issues I'm having on my iBook G4 (10.5.5) after applying the recent Security Update 2008-007. Basically all was fine before the update, and I ran software update and it picked up iPhoto 7.1.5, Migration Assistant (I think), and Security Update 2008-007. I installed them, it rebooted and now, although it's connected to my wireless network fine it won't find any internet sites and iTunes doesn't show any AirTunes speakers, or my Apple TV in the devices list. I've tried connecting via ethernet cable but that makes no difference. I can log onto my router using wireless or ethernet and all is ok with it. Plus other Macs and PCs on my network can connect to the internet fine (hence this posting) I couldn't find any answers on the net so I thought I'd restore from my Time Machine backup which I've duely done, but the wierd thing is that that has made no difference - it's still not connecting to the internet etc... Do TM restores restore everything? But that's another issue really... My question is really where to start? As I said I can connect to the router but not see any websites - that suggests a DNS issue to me, but the fact that iTunes isn't seeing my AirTunes speaker (and my other Macs/PCs can see it) is making me think it's something else... The Network Diagnostics utility can't fix it. All suggestions welcomed. Thanks Tim > My question is really where to start?

The > Network Diagnostics utility can't fix it. Couple of things I'd try first off: open Terminal and see if you can ping the Mac itself. Assuming you can, see if you can ping the router. Let us know the results. Another thing to check is to see if IPv6 has somehow got enabled and configured. If it has, deactivate it and see if that helps.

I can ping the router at 192.168.1.1 but not itself on 192.168.1.100. I can ping my XP laptop for what it's worth. IPv6 was set to automatic - I've turned it off and stopped and restarted Airport but that hasn't helped. I'll reboot just in case too... Thanks Tim > > > My question is really where to start?

And another update... iTunes now at least recognises my AirTunes speakers but I get an "unknown error (-3256)" when tring to connect to them. Also, the Apple TV is now recognised but when trying to sync it's saying it can't sync certain bought tracks as I'm not authorised to play them on this computer. I can't connect to the iTunes Store to (re) authorise the computer... Browsing etc still not working... Thanks > And another update... iTunes now at least recognises my AirTunes > speakers but I get an "unknown error (-3256)" when tring to connect to [quoted text clipped - 4 lines] > > Browsing etc still not working... Could you try turning off the firewall completely for a bit? Also, what values do you have in your DNS fields?

If the latter I've already done that. Airport is set up to use DHCP with manual address and the DNS server entries are blank. >> > And another update... iTunes now at least recognises my AirTunes >> > speakers but I get an "unknown error (-3256)" when tring to connect to [quoted text clipped - 16 lines] > Airport is set up to use DHCP with manual address and the DNS server > entries are blank. If you can manually add entries to the DNS fields, try putting in the IP address of your router. If that doesn't work try the following addresse:208.67.222.222 and 208.67.220.220 Those are the IPs for OpenDNS.

Then I put my ISP's servers in there, that didn't work, then I put the Open DNS servers in instead, that didn't work either. Then I stopped and restarted Airport and suddenly it's all working. The DNS entry now had four servers, the ISP ones (greyed out) and the Open DNS ones. I've now removed the Open DNS ones... So the only thing that's not working now is the AirTunes speakers in iTunes, though they play quite happily through Airfoil... need to keep investigating that one, and also need to try turning the OS firewall back on... Thanks for you help Jim and Chris... Tim >>> My question is really where to start?

As you think it is DNS (it does seem likely) then what does your /etc/resolv.conf look like? It should probably point at your router, but on the offchance your router's not responding properly to DNS requests, try pointing it direct at your ISP's nameservers. Before you change the settings, try doing a few manual 'dig's of addresses that ought to resolve. www.apple.com, for instance. SignatureChris > >>> My question is really where to start?
