how can i add a rule on my iptables to log the connections to my computer?


# Log all incoming TCP packets
iptables -A INPUT -p tcp -j LOG --log-prefix "---[LOGGED (INPUT)]:--- "

# Log all incoming UDP packets
iptables -A INPUT -p udp -j LOG --log-prefix "---[LOGGED (INPUT)]:--- "

Note that these rules will log EVERY INCOMING PACKET and your syslog logs will get pretty big.
