Guide: Firewall and router with Proxmox

August 31, 2009 | 48 comments

Firewall and router with ProxmoxBy default Proxmox does not come with a firewall, which may leave it and your virtual servers exposed to the elements of the Internet.

An additional issue arises when a hosting provider blocks servers if unauthorized MAC addresses are detected. As Proxmox’s bridged network creates and exposes MAC addresses for its virtual network interfaces, this may cause your server to be blocked from the hosting provider’s network.

To combat both this article will describe how to create your own virtual network with firewall protection using Shorewall, a popular and effective firewall / router software package.

X server with sound inside an OpenVZ / Proxmox container

August 24, 2009 | 3 comments

Generally when using X-based applications inside an OpenVZ or Proxmox container, the host node will run the X server and the container will use X forwarding through SSH to run the application. An article at the Open VZ Wiki explains this in more detail.

However, I wanted to have an X server inside the container itself. Moreover, it should also have support for sound (ALSA). The reason behind this is to have a container capable of running FreeSWITCH (a high performance VoIP switch similar to Asterisk) with the Skypiax trunk (for Skype connectivity) fully independent.

There are various methods of implementing the X server inside an OpenVZ or Proxmox container, especially if no direct video output is required. However, there is very little information available on how to enable sound inside an OpenVZ or Proxmox container. This article will explain how to do this. continue reading →

Guide: Installing OpenSolaris on a remote dedicated server

August 24, 2009 | 6 comments

There was an article at the OVH Wiki that outlined how to install OpenSolaris on a dedicated server with the help of Linux and Xen. This article is of special interest to those who have a dedicated server at a hosting company, but do not have the option to install anything but a Linux distribution.

Unfortunately, that particular article attracted a number of Wiki spammers and it disappeared in a sea of links to unscrupulous websites. I am reviving that article here, for those interested.

Finally up and running!

August 23, 2009 | 2 comments

Well, I’ve finally managed to get my personal website back up and running. I really haven’t had the time to do this until recently, and I wanted to do it right.

It’s based off WordPress this time, instead of my previous Joomla. An entire CMS was a bit too heavy for the occasional articles I write, but it certainly was a good experience!

The “monochrome” used has been created by mono-lab. Being the usual me, I have modified it quite a lot to fit my personal taste and the added widgets and other gadgetry hidden inside this website.

For instance, take a look at your right. In fact, why not click the “Translate this” link right now and see what happens. This nifty little trick will translate a web pages in-situ. Obviously, it is not done by a human translator so you will certainly encounter some quirky translations. Nevertheless, it can still help those who do not read English very well (and that’s not to be offensive!).

I’ll provide some more details on how I implemented this plugin from Transposh in a non-widget style with WordPress in another article. For now, I just want to get this first post out of the… yeah, what really? Door?

For those who know the inside joke: “Champagne?”
