Ubuntu 12.04.5 erroneously applies static IP to all interfaces

1

First, I'll start by saying this is a virtual machine in VMWare Player and I’m using Ubuntu 12.04.5 instead of the newest version of Ubuntu because it’s being used in an educational environment to learn some vulnerability testing strategies and mechanisms, so upgrading to the newest version is not an option.

Now, here’s my issue: ifconfig shows the correct IP addresses for each interface, as follows in this screenshot:

And then, as you can see by the following screenshot, when I specify the interface in a ping, it is applying the static IP from eth0 to eth1 and eth2, despite what it says in ifconfig. eth1 is set up in VMWare as a bridged adapter, and eth2 is NAT to replicate my host IP (I set up eth2 when the Bridged adapter wasn’t working, don't necessarily need both).

enter image description here

I’ve been messing with this for hours and nothing seems to be working to get this virtual machine out to the Internet.

I need to maintain the static IP for my Kali and Windows 7 machines to be able to do nefarious deeds without actually affecting a live network, but I also need to be able to access the web as part of my packet filtering and monitoring misadventures. Any thoughts would be greatly appreciated!

Good first question. And don’t apologize for using Ubuntu 12.04.5. It’s an LTS release that is still supported until 2017 I believe. And tons of real world servers are using it so you are not behind the curve; if anything you are avoiding getting cut on the bleeding edge of things! That said, perhaps posting the contents of /etc/network/interfaces where the configs are set can help people debug this for you. – JakeGould – 2015-10-01T05:11:16.527

Thanks jakegould, I'll post that as soon as I can get back to the vm – user3034550 – 2015-10-02T07:10:58.270
