I want to get the IP address through the LUA code. I have an example code that works but I get the IP from the LAN interface.

local hote, _ = socket.dns.toip(socket.dns.gethostname())

How can I get the IP from another wifi interface? it is possible to choose the interface?

I don’t know if the library socket allows this.

An alternative is to read the report of ifconfig with io.popen("ifconfig"):read"*a".

If you know the interface name, then you can use that name in the ifconfig.

Unfortunately, the format of the ifconfig seems to depend on the platform: they are different in Linux and Mac OS X.

IFCONFIG ON LINUX

If you want to know how to use the IP by ifconfig just do this in the note block:

print (io.popen ("LANG=C /sbin/ifconfig eth0"):lines ()())



print (io.popen ("LANG=C /sbin/ifconfig wlan0"):lines ()())

After saving with the name "MOSTRA_MEU_IP.txt", type this:

 ┌─[root@parrot] #lua MOSTRA_MEU_IP.txt                                    
eth0      Link encap:Ethernet  HWaddr 00:22:64:e0:d4:d4

wlan0     Link encap:Ethernet  Endereço de HW 78:44:76:9a:a0:47  

lo        Link encap:Local Loopback

DIR or LS

print (io.popen ("LANG=C /bin/ls"):lines ()())
