Getting IP address of machine from Pharo

Hello.

Do we have a way to retrieve IP address from Pharo?

I tried to use following code:

NetNameResolver addressForName: NetNameResolver localHostName

But it either not works (dialog with retry give-up options) or returns localhost 127.0.0.1.

Best regards,

Denis

Re: Getting IP address of machine from Pharo

What do you mean by your IP address, on your local network or the one seen by external servers when you connect to them?

If I remember well, the IP address seen by computers outside your local network is not the IP address of your actual computer but the one of the router connecting your local network to the outside web.

I am not sure you can get the outside IP address without asking it to a computer outside your local network but I might be wrong.

This is probably what you are looking for (one of the code snippets does exactly what you want).

http://forum.world.st/Figuring-out-external-IP-addresses-of-network-interfaces-td4937291.html

As for services/websites you can query to get the public ip address, here's a short list (you'll have to modify the example above to parse the response correctly):

http://checkip.dyndns.com
https://www.whatismypublicip.com/
http://freegeoip.net
https://who.is/
http://www.ipchicken.com/
http://www.whatsmyip.org/
https://api.ipify.org/
https://whatismyipaddress.com/

IMHO, the simplest is api.ipify.org. However, note that some of those service also answer geolocation info!

Re: Getting IP address of machine from Pharo

Ok, this one you can get it (for each network interface) via

$ ifconfig

In the command line. So I guess it should be possible to ask the OS via a FFI call what is the address.

I don’t know what is done in Pharo about that.

Apparently, on Linux using C, it is possible to get the IP address of an interface via a call to getifaddrs [1].

I don’t know what is the method to do that on Mac OS.

Re: Getting IP address of machine from Pharo

Yes, external lib is an option.

I expected that we already have something in the image.

We don't really, hence things like
