EPKPhoto's Tidbits » Ubuntu http://blog.epkphoto.com The personal blog of Eric Kerby Fri, 18 Feb 2011 02:52:24 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 New server up and running http://blog.epkphoto.com/2008/09/14/server-transition-feel-the-speed/ http://blog.epkphoto.com/2008/09/14/server-transition-feel-the-speed/#comments Sun, 14 Sep 2008 21:01:13 +0000 EricKerby http://blog.epkphoto.com/?p=226 As I mentioned earlier this summer, I built a new server to power several pieces of my network at home as well as my website and email services.  After much testing and careful planning, I can now happily say that the epkphoto.com website is running on this new server.  The site is now much more responsive thanks to larger memory and other resource allocations than it had previously.  Luckily, this transition happened with very few issues, so most would not have noticed the change until this announcement.  Read on for more details about the server.

The new server is not so special from a hardware standpoint…just another computer built from run-of-the-mill hardware in a nice CoolerMaster case.  The software setup is more interesting.  The server is running CentOS 5.2 and OpenVZ to provide container-based virtual machines.  More specifically, here is a list of major services that run on the hardware environment and in the virtual containers:

Hardware (CentOS 5.2)

  • iptables-based firewall/gateway/NAT router
  • DNS
  • Darwin Streaming Server
  • OpenVPN

Virtual Container 1 (Ubuntu 8.04)

  • Apache webserver (for epkphoto.com)
  • MySQL
  • Postfix SMTP
  • MailScanner
  • Dovecot IMAP

Virtual Container 2 (Fedora 9)

  • Apache webserver (for kerbyserver.net)
  • Netatalk AFP
  • BackupPC

My parents were kind enough to crash the Apple store earlier today when Leopard was released at 6pm. They picked up a couple T-shirts and a family pack of Leopard. If all goes well, I should be able to upgrade to the new OS this weekend (on my PowerBook at the very least).

As quite the bleeding edge Linux user, I'm amazed when I see uptime of this amount. If I managed my servers like a sane administrator, I would probably see uptimes in excess of a year, but my desire for testing the latest and greatest usually implies rebooting on occasion. In this case, my uptime streak is going to end in the next week or so when I upgrade to the latest Ubuntu version (7.10, Gutsy Gibbon). I have been waiting for this release for a number of reasons, not least of which include improved virus scanning speed for my email server and the latest ImageMagick and other packages to run the development version of the website I built for NASA Langley this past summer.

The Parallels issue I reported was not quite fixed in time for the release, but it looks like the fix will come soon. The unfortunate part is that this will likely affect all Parallels users that try to install Ubuntu in the next six months. At least the upgrade of epkphoto.com to Feisty Fawn went well. All I had to do was run "sudo apt-get install update-manager-core" and "sudo do-release-upgrade" as described on the Ubuntu upgrade page. I only had one hiccup when the upgrade halted due to a lack of memory. After fixing that issue and cleaning things up, the upgrade completed successfully. I altered a bunch of config files, so if you see something wrong with my website, email, etc. let me know! Now I can look to upgrade my other Ubuntu desktop/server at home. I want to wait though, since the computer has not been turned off now for over 152 days! I have to say I love Linux's uptime :) .]]> As you can see in the news section on the epkphoto.com main page, Canonical released Ubuntu 7.04 this past week.

I went to Washington, DC with some other students during the break, and I'll be sure to describe that more when I post the photos of the trip. In the meantime, I thought I would just mention that this quarter is off to a good start and could go many directions. I have an excellent set of interesting classes, so I can only hope for the best and keep up with the work to get the most out of them. While you have nothing else to do, feel free to check out a couple bug reports I filed on the Linux kernel in Ubuntu Feisty and Fedora 7 (I know, thrilling ;) ). You can find them at Ubuntu's Launchpad and RedHat's Bugzilla.

No need to talk much about that, though. I'd rather mention that the weather forecast is finally showing some temperatures above freezing within this next week here in Rochester. We have had solid packed snow on all the walkways across campus since it has been too cold to melt anything. That may change quite soon :) . Also, I am going to the hockey game tonight against Mercyhurst. It is RIT's last home hockey game of the season. Last night's game was an exciting win from what I heard, so I hope tonight's game lives up to that standard. Read on for Parallels and Linux comments.

When I last mentioned this topic, I was testing the "herd 2" release of Ubuntu's Feisty Fawn. The herd 3 release just about drove me insane as its installer continuously crashed my Parallels virtual machine. I never got a copy of it running in Parallels, but fortunately the herd 4 release that just came out installed just fine. I'll hold my judgments for the final release, but the Feisty Fawn version of Ubuntu is looking good so far.

I also have been having installation issues with the Test 1 release of Fedora 7. For some reason the installer DVD image begins to boot fine in Parallels, but the Anaconda installer fails to find a driver for the Parallels virtual optical drive. After trying many times to find an answer in IRC chat rooms, Fedora forums, and Parallels forums, I finally gave up and performed an FTP install of Fedora 7 Test 1. I set up a local FTP server on my Mac Pro with the installation files so the FTP install would not be hindered by downloading files. That worked flawlessly. I haven't had much time to test Fedora 7's new features, so I will hold judgment on it as well.

Another piece of Parallels news involves running Windows. I have Windows XP installed on a second hard drive in my Mac Pro using Apple's Boot Camp solution. With the recent couple beta releases of Parallels Desktop for Mac, I have finally been able to start up a virtual machine from my Windows XP Boot Camp install. Previously, Parallels could not handle Boot Camp configurations like mine that involved a second hard drive. Now that this has been fixed, I have access to Windows, multiple distros of Linux, and Mac OS X without any need to reboot my computer.

This is a much needed organizational upgrade.

It is currently at the alpha 2 (v7.04) phase of the Feisty Fawn release that is set to be finished and available by April 19th. I do say that one feature that really catches my eye is the new "Control Center" that consolidates a lot of preference and admin functions of the computer, similar to SUSE's YaST. This is a much needed organizational upgrade. I am a bit more excited about the planned features for Fedora's upcoming v7 release on April 26th.

Some of the upcoming features that are of interest in Fedora include:

  • Boot/Shutdown Speedup
    • This one plays off of work done in Ubuntu, to a degree. This will eliminate as much unnecessary junk as possible to greatly speed up the time it takes the computer to cold start or shutdown.
  • Encrypted Filesystems
    • This will be of most interest to government customers. This will allow an entire filesystem to be encrypted for protection of all data on the computer from unauthorized persons.
  • Fedora Directory Server
    • I have wanted better integration of this side project for a while. I have a couple reasons that I won't go into here to experiment with LDAP, and my past attempts at using OpenLDAP have not gone so well. The Fedora Directory Server approach should help me attain my goal.
  • Nouveau Drivers
    • This will provide some much improved open source drivers for nVidia video cards. Things still won't work quite as well as using nVidia's proprietary drivers, but the Nouveau solution should be much easier to install and supported right out of the box for new users.
  • RPM/Yum Enhancements
    • This area is one of Fedora's greatest weaknesses to most users. Yum and RPM are really quite powerful, but their speed is quite a bit slower than other package management systems out of the box. Some optimization and reworking of the update system should be a welcome change for Fedora users.
  • Wireless
    • Ubuntu tried to get this one right in their October v6.10 release. In my opinion, wireless network functionality increased significantly, but left much more room for improvement. I'm hoping Fedora 7 really goes the rest of the way to easy and functional wireless support. It will also help that the Fedora devs are going out of their way to try to include as many wireless firmware drivers as possible in the initial install.

I have high hopes for the next version of Fedora. I guess it is worth noting that a bunch of consolidation is happening, too. The official name for the distribution has dropped the "Core" part of the name to coincide with dropping the difference between the core and extras software repositories. Fedora will also be available in several versions optimized for desktop, server, etc. I guess that's enough to say about Fedora for now. It will be interesting to try the first test release after Jan. 30th.
