Like this part while reading some LISP doc

An even more impressive instance of remote debugging occurred on NASA’s 1998 Deep Space 1 mission. A half year after the space craft launched, a bit of Lisp code was going to control the spacecraft for two days while conducting a sequence of experiments. Unfortunately, a subtle race condition in the code had escaped detection during ground testing and was already in space. When the bug manifested in the wild–100 million miles away from Earth–the team was able to diagnose and fix the running code, allowing the experiments to complete.14 One of the programmers described it as follows:

Debugging a program running on a $100M piece of hardware that is 100 million miles away is an interesting experience. Having a read-eval-print loop running on the spacecraft proved invaluable in finding and fixing the problem.

here how facebook ot twiiter could be blocked … alot of lies and disturbed mode

http://www.cyberciti.biz/tips/linux-iptables-examples.html

iptables -A OUTPUT -p tcp -d www.facebook.com -j DROP
iptables -A OUTPUT -p tcp -d facebook.com -j DROP

for flush of rules

iptables -F


EDIT
not always work 🙁
added some code

iptables -I FORWARD -m string --string 'facebook' --algo bm -j DROP
iptables -I INPUT -m string --string 'facebook' --algo bm -j DROP
iptables -I OUTPUT -m string --string 'facebook' --algo bm -j DROP
iptables -I FORWARD -m string --string 'twitter' --algo bm -j DROP
iptables -I INPUT -m string --string 'twitter' --algo bm -j DROP
iptables -I OUTPUT -m string --string 'twitter' --algo bm -j DROP
