Itunes on my Mac freezed on " attendo che le modifiche siano applicate "

Question

Itunes on my Mac is freezed on "attendo che le modifiche siano applicate" while syncronizing my Iphone 5 , what should I do to exit from this condition ?

Answer 1

Of the second and third scripts, the latter could perhaps be deemed the "most secure"; however, it might block more than you want. If you really want to use one of those, then I'd suggest using the second script. Otherwise, I'd recommend that you take a look here. (I only slightly examined the first script.... I do not understand the language of the comments, and I'm no iptables whiz. )
Also, note that you don't have to use an actual script to set up the rules; rather, you can save the rules you want to a file that will be read by iptables automatically (/etc/iptables/iptables.rules). Here's a modified version of mine:
# /etc/iptables/iptables.rules
# These rules (and the commented instructions) derived from:
# http://ubuntuforums.org/showthread.php?t=159661
*nat
:PREROUTING ACCEPT [163:50538]
:POSTROUTING ACCEPT [40:2451]
:OUTPUT ACCEPT [40:2451]
COMMIT
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:FIREWALL - [0:0]
:TRUSTED - [0:0]
-A INPUT -j FIREWALL
-A FORWARD -j DROP
-A FIREWALL -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FIREWALL -i lo -j ACCEPT
-A FIREWALL -j TRUSTED
-A FIREWALL -j DROP
# put your own exceptions here, like so (replacing <tcp/udp> with either "tcp" or
# "udp" -- minus the quotes -- and <port number> with the port you'd like to open):
# -A TRUSTED -p <tcp/udp> -m <tcp/udp> --dport <port number> -j ACCEPT
COMMIT
Of course, there are benefits to keeping the rules in a script. For instance, you could then easily set the default iptables rules, allow all traffic, etc. Plus, some firewall-related things (such as the various echo commands in the scripts you provided) cannot (to my knowledge) be done by iptables alone.
If you already have a script that sets up the rules you would like to use, you can save yourself the hassle of creating a rules file by following the directions outlined here.
