    Should you see such an error when attempting to run FireFox from a remote terminal connecting to a local XServer (Xming, or similar) check the following:

    1. That the haldaemon is running
    2. That the dbus-x11 package is installed.? On RedHat based systems, you can yum install dbus-x11
    3. That you have fonts installed.? I did a bit of a brute force approach and ran: yum groupinstall 'Fonts'

  • Enabling Parsing and Processing of PHP code in Files With .html Extensions for GoDaddy.com Hosting Accounts
    11/20/2011 9:43PM

    There are times when a web master will want to have the default file extension for a given website stay consistent regardless of how the files are preprocessed on the server-side or what server-side scripting language is being used.

    To set up your GoDaddy.com 4GH, Linux hosted account to parse PHP code in .html files, do the following:

    1. Log in to your account.
    2. Go to the control panel for the web site in question.
    3. In the control panel click on the 'Settings' sub-section.
    4. Click on the 'File Extensions Management' icon/link.
    5. Click on the 'Custom Extensions' link in the left-hand column.
    6. Click on 'New Extension' in the upper right of the page.
    7. Enter '.html' for the extension, and select 'PHP 5.x.x' from the drop-down.
    8. Click 'OK'
    Once you click the 'OK' button you can now add PHP code to your .html files.
  • Cloned VMware CentOS6 Server and "device eth0 does not seem to be present, delaying initialization" Error
    11/17/2011 3:31PM
    Recently, I cloned a vmware install of CentOS6 and after firing up the clone and trying to start networking received the error: "device eth0 does not seem to be present, delaying initialization"

    It turns out that the NIC on the cloned machine was being renamed and registered to eth1.

    To list the current ethn devices:

    # ls /sys/class/net
    eth1 lo

    There is a device manager, udev, which stores the settings from the NIC of the vm prior to the cloning process.  When you clone a vm it also changes the mac address of the NIC and as a result the vm sees it as a new NIC and assigns it to /dev/eth1.

    As a result, we now have to edit the udev config file as well as the ifcfg-eth0 file to get the newly update virtual NIC card to operate on the eth0 device.

    First, edit: /etc/udev/rules.d/70-persistent-net.rules

    # This file was automatically generated by the /lib/udev/write_net_rules
    # program, run by the persistent-net-generator.rules rules file.
    #
    # You can modify it, as long as you keep each rule on a single
    # line, and change only the value of the NAME= key.

    # PCI device 0x15ad:0x07b0 (vmxnet3) (custom name provided by external tool)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:bc:00:45", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

    # PCI device 0x15ad:0x07b0 (vmxnet3)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:bc:00:46", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"


    Delete the first SUBSYSTEM entry in the file.

    Update the 'eth1' attribute in the remaining entry to 'eth0'

    Edit /etc/sysconfig/network-scripts/ifcfg-eth0

    . Change the HWADDR to match the new mac address listed in the newly edited 70-persistent-net.rules file.

    reboot.
