Re: bonjour connectivity stops



Thanks, I'll try that next time it happens (I can't 'make' it happen).

But my question is how is that different from doing a ping or ssh to the address g5server.local. Unfortunately I don't know much about the mDNS stuff.

I've search this list and seen the start of several threads about this issue but no resolutions so I'm posting my problem. If I've missed the resolution please point me to it.

I have an iMac G5 running 10.4.8 Client acting as a basic server for my home providing web pages and printers to my wired/wireless network. The iMac is hardwired to the main router. There is an EyeHome and another router (acting as a wireless node) hardwired to the main router and a couple of laptops and a TiVo that connect wirelessly. Every couple of days I can no longer 'see' the server using Bonjour. I can't ping g5server.local, I can't get the web service through g5server.local, I can't ssh to g5server.local, and I can't print. I CAN get web pages from http://10.0.1.10 (it's IP address) and I CAN ssh to 10.0.1.10.

I can resolve this problem two ways (other than rebooting the system)

1) I can simply unplug the ethernet cable from the iMac and replug it in.
2) I can go to System Preferences->Sharing and change the name of the computer to something else, and then back.


While easily fixed each time this is a pain. Is there something I can look at/do to track down the underlying problem?

What happens if you actively query the service? For example, could you try to see what happens if you use the dns-sd(1) tool after you can't access the webservice on g5server.local:


dns-sd -B _http._tcp

That should send an query out on multicast that the machine should respond to and update your local cache appropriately. As to why the record is disappearing from your local mDNS cache is beyond me, but actively querying for it should at least be a temporary fix for you. (Could one of those routers be filtering multicast or dropping the UDP packets at some point?)
