    Acer Aspire One – OCZ Vertex II SATA II SSD – Ubuntu 12.04 – Grub Error – Cannot read disk

Acer Aspire One – OCZ Vertex II SATA II SSD – Ubuntu 12.04 – Grub Error – Cannot read disk

I recently purchased an Asus Aspire One NAV50 (532h-2789), I wanted to use it for writing, but found it a bit too small for that task. It sat around for a few weeks while I figured out what to do with it… and figure out I did. Turn it into a gaming emulation machine running Ubuntu 12.04, DosBOX, and ScummVM.

To peak the netbook’s performance, I upgraded the RAM to the (max) 2 gigs, and also upgraded the manufacturer’s 160 gig HD to a OCZ Vertex II SSD (SATA II & 120 GB). A video outline the details concerning this […]

Wasting the producers in Wasteland 2

I still remember pulling Wasteland for the Commodore 64 out of a bin of ‘throw-away’ software when I was 6. It was 1990, the NES was gaining popularity and quickly reshaping how people gamed. So, despite being 1989’s Game of the Year, Wasteland for the Commodore 64 was seen (prematurely) as ‘outdated’.

The box was similar in size and shape to that of a 33-LP vinyl, adorned in finely detailed hand-painted graphics; an artist’s vision of a post-apocalyptic southern California.

What inquisitive mind couldn’t be drawn in by that cover? A gang of five desert warriors facing a lone stranger midst the blown-out rubble of a city street. […]

Avaya phone-script from g350 to Ubuntu 12.04 TFTP server

As the Alta3 Research office network grows, I decided it was prudent to explore/develop how to bring up a TFTP (Trival File Transfer Protocol) server, primarily for use with our Avaya 46xx stations. In this post, I’ll explain how I moved the TFTP service from an Avaya G350, to an Ubuntu 12.04 LTS server.

Before I get started, some basic things about TFTP. TFTP is typically used for diskless boots (routers and phones), and across UDP port 69. TFTP offers no way to ‘list’ files available from the server. The protocol also lacks any security authentication, therefore, TFTP should never be implemented, […]

    Asterisk 1.8 – dial CLI command – No such extension ‘401’ in context ‘default’

Asterisk 1.8 – dial CLI command – No such extension ‘401’ in context ‘default’

This post is regarding Asterisk 1.8.11.0

When logged into the Asterisk CLI, you can send ‘test’ calls via the following command:

console dial <extension>@<context>

The following example would place a test call to extension ‘555’, found in the context ‘zorkfan’:

console dial 555@zorkfan

Failure to use the ‘@<context>’ portion of the command will result in Asterisk looking for the extension in the context ‘default’. If you don’t use the context ‘default’, then you’ll see the following error displayed:

No such extension ‘<extension>’ in context ‘default’

Finally, failure to use the ‘console’ portion of the command will result in the Asterisk CLI displaying the following error:

No such command “dial […]

    Avaya Aura Template Installation from System Platform – Could not mount DVD/CD

Avaya Aura Template Installation from System Platform – Could not mount DVD/CD

I recently spun Avaya Aura 6.2 Mid-Sized Enterprise software onto an HP DL360G7 server. After the installation of System Platform, the process requires that you install the VM templates. Avaya recommends that this be done by downloading the template *.iso files from the PLD, and burning them to DVDs. After creating the DVDs, you log into: System Platform > Server Management > File Manager, place the first template DVD into server, and click the, <View DVD/CD> button. Unfortunately, no matter how many times I tried this, or how many DVDs I burnt, I was unsuccessful in getting the Avaya Aura to mount […]

Fix – solution for HP 8100dn printer 79.00FE error

This is a fix / solution for the 79.00FE error as displayed on a HP 8100dn printer, however, I understand that this can also apply to the 5Si, 8000, 8150 series printers. When this error is encountered, the printer will become unresponsive, but may still be accessible via the web GUI.

79.00FE usually means a that the jet-direct card is receiving information that it cannot interpret (PDF files seem to often be the culprit). Here is some documentation to back up that claim HP’s 79.00FE Troubleshooting Guide. If my quick fixes don’t work, be sure to review it.

Quick Solutions:

1) Turn off the HP printer. […]

    Windows 7 – Solution / Fix – The settings saved on this computer for the network do not match the requirements of the network

Windows 7 – Solution / Fix – The settings saved on this computer for the network do not match the requirements of the network

I recently changed out my ‘core’ Linksys router, for a more ‘hackable’ Asus. Both routers were running similar versions of dd-wrt, and I was careful to make sure I kept all of the same setting when provisioning the new Asus. Still, the result was that all of the devices on my LAN running Windows 7 were suddenly met with limited network connectivity, displaying the following error:

The settings saved on this computer for the network do not match the requirements of the network

Each laptop had it’s own set of unique symptoms. Some were cycling the network adapter on and off, others refused to connect to […]

Script to compile the latest version of Asterisk v1.8

I wrote this script in vim on an Ubuntu 10.04 LTS box, to stand-up the latest version of Asterisk. At the time I wrote this script, the latest version was Asterisk v1.8.11.0; however, this script maybe easily tweaked to install any version of Asterisk you like. You may find the latest (and almost every) build of Asterisk here: http://downloads.asterisk.org/pub/telephony/asterisk/releases/

After visiting the above URL and determining which version of Asterisk you wish to install, simply change the parts of the script that are relevant to that version (i.e. 1.8.11.0.tar.gz), and let it rip. If you don’t know what, ‘let it rip’ […]

(How to launch a *.msi file) wine: Bad EXE format for *.msi

I’m running Ubuntu 10.04 LTS. After installing Wine-1.2.2 (type wine –version to check) via sudo apt-get install wine within a CLI terminal, I tried to install a *.msi file via the following syntax:

~$ wine install.msi

Unfortunately, this produced the following error message to be displayed:

~$ wine: Bad EXE format for Z:homeziffstarinstall.msi

The solution, to install *.msi files in Wine, is to use the msiexec program. The appropriate syntax to launch a *.msi file is as follows:

~$ wine msiexec /i install.msi
                    OR
~$ wine start install.msi

    ./pcscf.sh: line 4: setkey: command not found || fix for OpenIMSCore

./pcscf.sh: line 4: setkey: command not found || fix for OpenIMSCore

When trying to launch the pcscf.sh, you may encounter OpenIMSCore hanging, and displaying the message:

./pcscf.sh: line 4: setkey: command not found
./pcscf.sh: line 5: setkey: command not found

I was able to fix this problem on Ubuntu 10.04 LTS by opening a terminal and typing:

sudo apt-get install ipsec-tools

Apparently, setkey is included with the ipsec-tools apt-get. After the install, my issues with this particular error went away.
