Open ports...

[holmBrew]

I did a port scan on my box and found the results a bit strange. These ports were found to be open:

Open Port: 22 ssh
Open Port: 111 sunrpc
Open Port: 427
Open Port: 770
Open Port: 773

what are ports 427,770, and 773 open for?

To find out what process is listening on those ports, open a Terminal and run,

sudo lsof -i :427

(and for 770 and 773). My guess is the 770 and 773 are NetInfo stuff.

Does this mean something to you?
