Mr. Rupesh,

although you didn't want to contribute to your previous thread named 
"How I can send a Packet to every Body on Internet" we can answer 
questions regarding the security of your box.

You could use in conjunction with that iptables command the --log-prefix 
switch kinda like this:
iptables -A INPUT -p TCP --dport 8000 -j LOG --log-prefix 
"crap_that_will_identify_the_log_rule"

After that you can use this command to get the entries in the syslogd log file:
cat /var/log/syslog|grep "crap_that_will_identify_the_log_rule".

The misteries involving this can be read with the command that unlocks the power of the iptables:
man iptables
