I am unable to ping it either. However, my phone works so the connection must be alive. if you can't ping it, i doubt anything other than snmp or cacti (or whatever network monitoring tool might suite your preference) will help you much. chances are that the phone does what my tv (and mac mini on default configuration) does - goes to sleep until it needs to do something. Any other ideas? yeah, rtfm: -sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans -sU: UDP Scan -sN/sF/sX: TCP Null, FIN, and Xmas scans other than that, nmap.org and insecure.org have tons of docs. you can probably even find someone asking about scanning your phone. there is also a talk that the lead dev did about 'scanning the internet' you can probably google for (or is probably linked to on their page) that was given at defcon a few years ago. you can also fire up wireshark and see what your phone is doing and figure out how to handle it from that point. if it wakes up when you get a call, you can probably write some simple lua plugin to find it (i don't think it's that hard though). if you get stuck, check #nmap on the freenode irc. it's not very active but pretty helpful folks stay in there. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Though, you might want to exclude any local addresses from netstat so that you don't mess anything up in the process. Also it would probably be fun to reset an arp cache while connected to an l2tp vpn. ... though if you can easily set the stale time to something short like a second and then put it back, that might have the same end result you want with less work. Though, this is just something to do for fun or in special cases. DON'T DO THIS ON NORMAL X86 DEBIAN INSTALLS. There's just no reason. Do you use a tooth pick to spread butter on your toast? Why, it might be fun or something...? Again, the right tool for the job - nmap, hping, scapy all come to mind. If you want to monitor your network, nagios, cacti, etc. Than again, maybe you're the type that wants to win the guiness record for 'fastest man in a baby stroller' ok, actually that sounds fun. Maybe that's why I've done this before :)

Remember that your router will show up w/ an IP in use as well as each computer you know about on your LAN, so if you have more IP's in use then computers, start hunting *and secure your wireless*!!! -- A: Yes.
