Internet connection sharing (ICS)

Suppose a laptop can connect to the internt through wireless. We want to use its ethernet port to share internet on another device (e.g. raspberry pi where the device has only ethernet port).

1. control panel - network & sharing center
2. manage network connection
3. right click wireless network connection and select property
4. click 'sharing' tab and check 'Allow other network users to connect through this computer's internet connection'. For the home network connection, select 'Local Area Connection'.
5. reboot raspberry pi.

Create a VB script text file "ip.cbs" with a content like

Option Explicit
Dim http : Set http = CreateObject( "MSXML2.ServerXmlHttp" )
http.Open "GET", "http://icanhazip.com", False
http.Send
Wscript.Echo http.responseText   'or do whatever you want with it
Set http = Nothing

Open a command line and run

cscript ip.vbs

• On windows, open a command prompt. Type 'ipconfig' and look at IPv4 Address. But 'ipconfig' cannot show only one adapter. Another choice is netsh

x <- shell('netsh interface ip show addresses "Local Area Connection"', intern = T)
y <- strsplit(x[grep("IP Address", x)], " ")[[1]]
y[length(y)]
# [1] "xxx.xx.xx.xxx"

Notepad++
