How can one find IP addresses on a LAN when connected by WiFi?
Try an Android device running fring...Not a lot of help when I'm sitting here on a boat in France with two Beaglebone Black systems, an IBM Lenovo laptop, a Siemens Gigaset VOIP phone, an internet radio, but nothing running Android.
It's possible my reply has sent twice, as I'm having some problems with K9 Mail on my phone but...
Does "nmap -sL 192.168.1.* (or whatever the LAN address is) | grep lan" do what you're after?
The -sL flag is the basic scan (you could use -pn for a ping scan, if everything had an open port to respond) and various others (check the manpage for a full list of scan types) and will return a list of IP addresses and device names for everything that matches the IP range and has a .lan network address.
