  • File Transfers without SSH
    11/16/2016 9:03PM
    I had an interesting problem at work related to copying files from one Linux server to another.  The problem was this: I had login access to both servers and on each server I had sudo access to a service account, which does not have login access.  The files that I had to copy were owned by the service account and many ...

  • Adventures in Virtualizing a Linux/CentOS 5 server that has three RAID1 volumes
    04/04/2016 3:41PM
    This is here mostly so I have something to refer back to:  A server my buddy Duncan runs is growing long in the tooth but we are not ready to retire it. It's a Linux CentOS 5 install running RAID1 across two physical drives. It seemed to make sense to turn it into a virtual machine running under [VirtualBox][1].  We ... Read Full Article
  • Ubuntu 14.04 LTS nodejs npm install generates sudo unable to resolve host error

    In attempting to install grunt under Ubuntu 14.04 I kept getting the infamous error: **grunt@0.4.5 /home/yml/sudo: unable to resolve host cylon ** However, in my case I had resolved the sudo error some time ago by setting /etc/hosts and /etc/hostname correctly. It turns out that while installing Titanium Appcelerator ... Read Full Article
  • Lubuntu disregarding disabling light locker screen locker settings
    11/01/2014 2:27PM
    It turns out the system wide light locker (Screen locker password prompt after inactivity) setting incorrectly overrides the per-user account one.  Move the system wide one to a backup file: sudo mv /etc/xdg/autostart/light-locker.desktop /etc/xdg/autostart/light-locker.desktop.bak Then make sure the Exec= line is e ...

  • Getting WIFI Wireless to work under Lubuntu 14.40 on a Thinkpad X100E
    10/30/2014 1:02PM
    This represented over an hour of my life. After upgrading to Lubuntu 14.04 LTS on my Lenovo Thinkpad X100E, I was unable to enable the wifi adapter.  In a terminal window "rfkill list" showed that wlan0 was soft-blocked. Enabling it using rfkill did not solve my problem as the UI would continue to show wifi as disabl ... Read Full Article
  • Converting a Physical Server to a Virtual Server using VirtualBox
    08/26/2014 10:20AM
    We had to move the servers back upstairs. Given that vetsclub is very long in the tooth we were afraid it wouldn't come back up. So a a fallback, in case it failed to boot, we decided to create a virtual copy of physical vetsclub. The recipe is pretty straight forward. Because the machine is so old, Duncan pulled the ...

  • A Raspberry Pi Media Server
    06/27/2014 5:19PM
    So for the longest time I've been showing videos and photos on the big TV by copying everything over to a spare USB drive and then plugging it into the PS/3. It works, but it's klunky. What I really wanted to do was set up a generic computer that I could plug directly into the TV and use it to show videos (mostly ... Read Full Article

    So I was getting permission denied errors when attempting to establish an outgoing network connection to an smtp server from a PHP script running under the Apache webserver on a Fedora Core 13 box.  To get familiar with it, I've left SELinux enabled and, as they occur, I track down the issues it raises.

    You would think that an editing tool would be included by default but it is not. So after some searching I discovered the tool needed is "alacarte". To install, as root in a terminal window: yum install alacarte After installation there will be a new menu item called System->Preference->Main Menu which will let you e ... Read Full Article

    I'm repeating my experiment with the Lenovo Thinkpad X100E. I picked one up directly from Lenovo. The product page is [here][1]. (not an affiliate link) I got the "Elite" version with the AMD Turion Neo X2 Dual-Core L625 (1.6GHz, 800MHz, 1MB L2) processor, 4 gigs of ram and a 320 gig drive. It's got a realtek wire ...

I wanted to use the dates of the photos to copy them into separate directories spanning the fo ... Read Full Article

    I have finally given up on Ubuntu 9.10. I should have done that some time ago. I've switched to Fedora Core 12, which I was loathe to do because of some very bad experiences with previous versions. I'm happy to report that FC 12 suffers from none of the problems I saw in Ubuntu.  Networking works. Sound works. It' ... Read Full Article
  • Slow DNS Lookups in Ubuntu 9.10 (Karmic Koala)
    01/28/2010 11:28PM
    One of the most frustrating things about Ubuntu/Kubuntu 9.10 (and 9.04) is the random but frequent 20 sec DNS lookup delay that happens when IPV6 is enabled. Apparently, the resolver first attempts an IPV6 lookup, even if no interfaces are defined. It will sit and time out, at random, for 20 seconds before attempting t ... Read Full Article

    The machine this site is running on is an old dual PIII 600.

So while I work on a replacement for those components, we're stuck running dns1 for the foreseeable future. The ma ... Read Full Article
