Virtual Appliance with Debian Squeeze and OpenWRT-XBurst Development Tools for Qi Hardware’s Ben Nanonote

This post is about a Virtual Appliance with Debian Squeeze and OpenWRT-XBurst Development Tools installed, which would allow immediately compiling OpenWRT packages for the Nanonote without going through the painful process of setting up the development environment yourself.

As a non-developer, I found a working development environment to be the single most confusing part of porting to the Nanonote, even more confusing than OpenWRT’s Makefiles. Granted, this could be my personal lack of talent or skill, but it left me thinking removing this “steppingstone” for some of the less experienced users might open more doors, faster, for beginning Nanonote enthusiasts. The instructions at http://en.qi-hardware.com/wiki/Building_OpenWRT_on_Debian_6 are great, but might slightly intimidate less experienced Linux users. They are also slightly daunting to follow if the need arises frequently (if reinstalling OS, royally screwed something up, or other scenarios I’m sure you ran into).

The easiest way to get around this I could come up with was creating a Virtual Appliance which contains the basics for compiling for the Nanonote, using the wiki instructions for Debian Squeeze. Such an appliance can be run in VirtualBox (free and open source) or VMWare Player (free as in beer), even on Windows hosts. The result is a single 2.4 GB file with a ready toolchain which is ready to “accept” package Makefiles and compile them. Debian was installed, the toolchain was compiled, the locales and paths were set. I gave it a quick test compiling Pem (and a load of Perl dependencies) and it seemed to work.

The Virtual Appliance is currently unimaginatively called “Debian Squeeze with OpenWRT-XBurst Development Tools 2011-08-27” and comes as a single .OVA file. See details below:

Instructions
1. Install VirtualBox.
2. Download Virtual Appliance .OVA file (links below)
3. In VirtualBox click on “Machine” > “Import” and select the .OVA file.

I’ve added a brief section under the Building on … Debian Squeeze wiki page.

Hope someone finds this helpful.

Monitoring Amazon EC2 instances and other Cloud Resources with Hyperic HQ (and other monitoring platforms)

I’ve had to tackle this task recently and could not find a write-up. Nice folks from Hyperic, and others on Twitter, suggested OpenVPN or an SSH tunnel. I opted for the second option, and after setting up two tunnels and properly configuring the agent, I now have an Amazon EC2 Windows instance show up as a platform in my Dashboard. Note that those instructions will work for other software (Zabbix comes to mind). Here’s how you can have yours too:

1. Install an SSH server on the to-be-monitored cloud instance. For Linux, OpenSSH is easy to install and setup, and usually already comes with most distributions. All you have to do is create a user and a password, or keys. On Windows, CopSSH will do the trick – you just have to add a new user and configure it through the CopSSH control panel. Make sure the SSH server runs, and the login credentials work.

2. Install an SSH client on your Hyperic HQ server. For Linux, again, OpenSSH will do the trick and is most likely already there. For Windows, try CygWIN or PUTTY.

3. Designate a unique name for localhost in the hosts file of both the Hyperic server and the cloud instance. In Linux, it would be under /etc/hosts. In windows, it moves between versions but is usually under C:\Windows\system32\drivers\etc\hosts . Call it cloudagent1. The line should look like this:

127.0.0.1     localhost cloudagent1

4. From the Hyperic server, initiate an SSH tunnel which forwards two ports. First from the cloud instance to the Hyperic server (usually on port 7443). Second from the Hyperic server to the cloud instance, to the port on which the Hyperic agent runs. If you already have a Hyperic agent on your Hyperic server, you MUST use a different port. As the local agent usually runs on port 2144, you may want to pick something like port 22144. With OpenSSH on CygWin and Linux you can create the tunnels like this (assuming your username is “user” and your cloud instance is “cloud-instance.com”):

$ ssh user@cloud-instance.com -R 7443:cloudagent1:7443 -L 22144:cloudagent1:22144 -N -f

5. Configure the Hyperic agent on your cloud instance to use port 22144. The rest of the settings can be copied from your locally monitored agents. You can use “cloudagent1” (or whichever name you have assigned to the localhost) in the configuration.

Hope this helped!
