I write code

Month: February 2012


This weekend I built a simple little Linux program that scratches an particular itch of mine.  As part of my daily work I need to log in to various Linux VMs.  The problem is that the IP addresses of these VMs often changes due to them being configured to use DHCP.  I suppose I could have changed them to have static IP addresses, but that would be too easy 😉

Instead I have written a little program I call FrontDoor that gets loaded by getty and displays some basic information about the host, including things like the IP address and so on.  Now I can just look at the VM on my desktop and see the IP address at a glance 🙂
