In general I have incoming connections disabled by my security software (Little Snitch). But even when I do this, on public wifi, I see numerous incoming connections for
mDNSResponder allowed automatically.
For example, at a recent hotel stay, I was confronted with a long list as soon as a logged on to the wifi there (listed as automatically allowed by Little Snitch)
which quickly grew to the thousands
What are these incoming connections for? Why are they being automatically allowed? Are they a security threat?
Note that if I explicitly block all of these connections using Little Snitch, my network access fails, but the network still seems to function when I alternatively block incoming connections using Apple's (OS X 10.9) firewall
and enable stealth mode
