So i have used OSX for a very long time...
when i upgraded to snow leopard, one of the first things i did was install little snitch and noobproof...
After installing firewalls, I went to disable mDNSResponder on my laptop and iMac... bonjour=mDNSResponder... which is a really stupid service for someone like myself (doesnt need to advertise my existence to current networks)... Bonjour has always had its ups and downs... BUT
WHEN YOU DISABLE BONJOUR/mDNSResponder YOU CANNOT ACCESS THE INTERNET AT ALL THROUGH SAFARI!!!
Once Bonjour is dissabled from snow leopard via terminal command:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
or by disallowing network connections to the service via a firewall...
I CANNOT ACCESS THE INTERNET VIA SAFARI OR OTHER!!!, my network settings remain the same, claiming I have connection... I have to re-enable access/turn on mDNSResponder to gain access to the internet again.
When highlighted in little snitch, the services purpose is:
"is necessary for local host name resolving."
I do not know if Snow Leopard some how has relied on Bonjour/mDNSResponder to assign basic network connections, but it totally nocks out all internet to my intel iMac 22"
Please, if anyone can explain why this happens after Snow is installed, or can solve it, let me know immediately...
If you dont know why, but have experienced the same thing, please leave a comment on how u disabled and what problems you receive afterwards.
UPDATE: Randomly, if left off, my transmission (torrents) will lose connection and then regain connection just to drop again, but safari is still not active when mDNSResponder is left off, I also tried command without -w... Yet, when i give netstat (terminal) i still see "ESTABLISHED" connections (torrents) while no activity is being passed through... so bizzar
UPDATE: I found this in iana.org Block all of these via firewall, in and out (littlesnitch/noobproof):
mdnsresponder 5354/tcp Multicast DNS Responder IPC
mdnsresponder 5354/udp Multicast DNS Responder IPC
cuseeme 7648/tcp bonjour-cuseeme
cuseeme 7648/udp bonjour-cuseeme
mdns 5353/tcp Multicast DNS
mdns 5353/udp Multicast DNS
Update: i found a site that claims to have links for new snow leopard support, one of which "disabling bonjour service advertisements without disabling mdnsresponder"... which is what i have been waiting for!!:

BUT THE SECOND LINK IS BROKEN!!! i still dont know how to do this!! and it looks like it was an APPLE Support site, now broken... not cool
