+======Hear your Firewall======
+This little script watches the ''/var/log/kern.log'' for the string ''[FW] default'' which is logged by my firewall when dropping a packet. For each map a little beep is sent to the pc speaker.
+You need ''beep'' for it.
+  #> apt-get install beep
+<code bash>
+#!/bin/sh
+tail -f /var/log/kern.log | \
+ awk '
+   $0 ~ /\[FW\] default/ {
+     match($0, / DPT=([0-9]+) /, matches);
+     port = matches[1];
+     print port;
+     if (port < 1024) {
+       system("beep -f 500 -l 100");
+     }else{
+       system("beep -f 2000 -l 100");
