Dual Boot Ubuntu and Linux Mint with Shared /home

Lumière is a system I built a couple of months ago to be a pure Linux-only machine. I haven’t done much with her, but it’s time to change that. As I’ve posted before, I really wanted to run different distros through their paces in order to weigh their pros and cons. However, I also wanted to have a system that I could actually use, so I decided to do a multiboot system with shared /home partitions.

Last night, I decided to start off easy and add Linux Mint (Felicia) on top of Ubuntu (Intrepid Ibex). Now I say that this is easy since Linux Mint is actually a modified version of Ubuntu (which also happens to be a modified version of Debian). Since Linux Mint and Ubuntu share a similar structure, all the user and group IDs would be the same. This means that setting up a shared /home partition would be much simpler.

I also wanted to use Linux Mint since it has been highly recommended to me many times.

smrsh: “php” not available for sendmail programs (stat failed)

I had to configure Sendmail in order for Ubersmith to be able to receive support requests via email. Basically, you configure an alias (/etc/aliases) like so:

support: "|php -q -f /home/html/cron/gateway.php domain.com 1"

This all seemed to be very straightforward. I didn’t even think to test it until hours later. When I finally did test out the support request by email function, I received this very abrupt rebuke from Sendmail in the form of a bounceback:

Configuring Sendmail to Receive External Mail

I’m having all sorts of fun playing around with Linux these days, both on my personal systems and on servers. Earlier, I had to configure Sendmail to receive outside mail. I’ve used larger mail solutions on Linux before, such as Qmail, but I didn’t need anything near that complex since I just needed to make sure that this server could receive specifically routed messages.

When I first started digging around, I couldn’t even find out how to change any of the settings, but it was clear that the server was only listening on the localhost loopback address. Even my usual solution of googling for answers wasn’t turning up much. Finally, after searching for about half an hour, I found this extremely helpful guide, which I will simply direct you to if you wish to get Sendmail configured on your box.

Good luck.

Trouble with Ubersmith, Ioncube, and mb_internal_encoding

Today I’m installing Ubersmith, a billing system solution, on a server to test it out. I have to say that Ubersmith has a more complex installation process than I’m used to these days. I guess that I’ve been spoiled.

Here’s a quick word about what I’m running. My test server is a dedicated system running CentOS 5.2 64-bit. The software setup is nothing special as most of the packages are straight from the repository.

I loaded the release files on the server, untarred them, and proceeded to read the instructions. Everything looked to be straight-forward. I quickly got down to the part about installing Ioncube. That’s when the trouble started.

Hide Desktop Icons in Ubuntu

My quest for the perfect Ubuntu desktop continues.

Today, I really wanted to remove all of my desktop icons since I like using that area for storage, but I don’t like having all that stuff strewn across each of my workspaces since I never actually use the desktop itself. I searched around and found some helpful information, but it really didn’t do what I wanted. I’ll provide that information in case it does what you want.

The Configuration Editor is Ubuntu’s (more acurately, Gnome’s) application that lets you control a massive number of options that all work together to present your desktop, file browser, windowing system, etc. You can add and remove system generated icons from the desktop by using the Configuration Editor (from now on referred to as Gconf. To load Gconf press “Alt+F2” to bring up the Run Application dialog, type in gconf-editor, and click Run.

Adventures with Ubuntu Continued

I’m now on my fifth day of using Ubuntu on my office machine. Slowly, I’m starting to get accustomed to working with it, but there are still a variety of things that I still need to do from time to time.

For those that haven’t read my previous posts on this topic, I’ve switched from Windows Vista to Ubuntu Intrepid Ibex (8.10) on my Dell Studio 17 laptop that I use at the office. Even though Ubuntu has a great ability to “just work,” often times it is difficult and unintuitive to get certain things to work. So, I decided to blog about all those difficulties so that I can have this information to rely on later and so others can benefit from my experience.

Fixing a Broken Graphics Card’s Fan

Samus, my main machine, was having some issues earlier today, so I opened her up and felt around. I touched the graphics card and was nearly burned. I loaded up a temperature tracking program and found that it was running at 93°C. That’s nearly 200 degrees Farenheit. I was amazed that the GPU hadn’t been damaged by this heat.

First Day with Ubuntu at the Office

I got Ubuntu successfully installed on my office machine (Dell Studio 17) yesterday. Today, I’m going to use it all day at the office while making notes on what still doesn’t work, what I could get to work, how I fixed problems, and I’m sure some random ramblings will enter at some point.

W2k9? AKA: The Planet is Down?

It looks like there is a big networking problem over at The Planet. Hostgator, which hosts this blog and is hosted by The Planet, is suffering terribly from this problem. My uptime with Hostgator is so high, that Pingdom tracks my site at 100% uptime since it doesn’t track beyond 99.99% uptime. So, this has to be causing lots of stress for the engineers at both companies.

I first noticed this problem when working on a site that is hosted at Hostgator. The site completely failed to load and pings failed 50% of the time.

Setting up Ubuntu on my Dell Studio 17

I have a Dell Studio 17 for my office computer. It’s a nice machine, but Vista fails horribly on it. The ATI driver for it causes a BSoD on average, once a day. I’ve finally had enough, so I’m switching over to Ubuntu 8.10, Intrepid Ibex.

I’m writing this post as I install and configure Ubuntu. This will make it easier for me to keep track of what I did in case I need to undo something later or if anybody reading this wants to make the switchover as well.
