I've seen running netstat that there are two strange tcp connection opened:

tcp4       0      0  localhost.49153    localhost.1023 ESTABLISHED
tcp4       0      0  localhost.1023     localhost.49153 ESTABLISHED

I wonder if it is normal. Can someone help me? thank you!

Yes, that's just normal loopback used by OS X. Checkout a Apples port usage publication
