Personally I LOVE THE NEW GUI (not that different =), and have encountered little-to-none problems, just a few betas is all, no crashes, none of the stuff ive been seeing on this thread...
*********************************************************
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!!!
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:
Well, I havnt solved it, but I can at least limit it... here is what i did (without "disabling via terminal" which leaves no connectivity)...
Using LittleSnitch I was able to block access to mDNSResponder, but when this is done by itself, it gives limited access to the internet... when i say limited, safari would not load some websites/parts of the websites and would hang on the load... but my torrents download fine in background (firewall configured for torrent port)...
SO, I denied all access to ff02::fb, 224.0.0.251... and then made a rule ALLOWING only access to the router IP, this i believe will stop some of the security holes that bonjour brings...
UPDATE: I also blocked incoming traffic on Ports 7648 and 5354 with NoobProof
NOTE: in the network monitor, these are what gets connected to mDNSResponder:
RouterIPAddress
ff02::fb
User.local
224.0.0.251
DO NOT TRY TO BLOCK YOUR User.local!!! It will crash your littlesnitch for obvious reasons!! =)
Im gunna mess around a bit more with what to block and allow...
QUESTION:
1) Does mDNSResponder receive or listen for "incoming" connections from other computers which have bonjour/mDNSResponder on?
2) If so, than what port/protocol can i "block" within my "incoming" firewall (NoobProof)?
UPDATE: I found this in iana.org:
mdnsresponder 5354/tcp Multicast DNS Responder IPC
mdnsresponder 5354/udp Multicast DNS Responder IPC
cuseeme 7648/tcp bonjour-cuseeme
cuseeme 7648/udp bonjour-cuseeme
So, anyone know of any better ways to stop mdnsresponder from spreading its VD all over my computer?
PS: For all of those saying there SL is crashing and they cant run the apps they want... im running adobe, adobe update, littleSnitch, NoobProof, PeerGaurdain, Growl, HardwareGrowl, Transmission (1.2mb/ps) and much more with no problems.... (most of which are betas)... hers a sneek peek:
