Get my external IP - the Linux way

[zWaR]

Hehe, It was kinda amusing reading about the windows CMD (http://evilzone.org/delphi-and-pascal/cmd-tool-to-get-external-and-local-ips/) way to show your external IP. Could not resist to post a possible linux way to do it

Code: [Select]

curl ip.nu

Or to get a clean output:

Code: [Select]

curl -s ip.nu | egrep '[0-9]' | awk '{print $5}'

Well I had made a tool for that too:

Interesting ... (I'm not sure where to post the comment ... here or there ... but let's make it here)

Must confess the script is really ugly (as xzid allready mentioned)

Re the local ip, the line below is much simpler than what you suggest (works on linux, dunno for bsd and sunOS):

Code: [Select]

hostname -I

In case you have more than one ip, using cut can help to extract only one, e.g.:

Code: [Select]

# extracts the second ip
hostname -I | cut -d' ' -f2

This does not work for people behind a router I believe.  This will get you the internal IP in that case.

Code: [Select]

#! /bin/bash

wget -qO- icanhazip.com

Very simple.

I did this kinda thing in python a while ago: https://forum.intern0t.org/hacking-tools-utilities/4050-getmyip-get-your-ip-address-command-line-extra-options.html

wget -q -O - checkip.dyndns.org | sed -n -e 's/[^[:digit:]\|.]//g' -e 1p

True, like i said, hostname -I returns a scripting friendly internal address. The first post (among others) talks about external addr retrieval.

... hmmm.. i've always used

Code: [Select]

curl -s ifconfig.me

Hehe, there are some people in this place using linux after all, nice! Great to see all the different ideas!
