I would like to monitor who connects to my iMac's WiFi hotspot. I have protected it with a password, but WEP is easy to crack. Is there a utility for OS 10.7.3/Lion to see who is connected?
Here is a command I let in an
Terminal) running to be aware of neighbour
attempting to enter my WEP unprotected Wi-Fi network:
/usr/bin/sudo tail -f /var/log/system.log | grep 'bootpd.*\[en.\]'
When this window starts to scroll, I know I got a new uninvited guest at home.
If I want to know afterward who attempted to access my network, I can find it with:
/usr/bin/sudo grep 'bootpd.*\[en.\]' /var/log/system.log
