Getting ClearOS to work with Atheros Communications AR8151 v2.0 Gigabit Ethernet (rev c0)

2012-01-30T12:17:07+00:00

ClearOS formally Clarkconnect based of Centos…

Start by enabling the Tim S repo

To install the repo first install the public key (yes all RPM’s will now be signed)
rpm --import ftp://timburgess.net/RPM-GPG-KEY-TimB.txt

Then install the release RPM (by default the ‘timb’ and ‘timb-testing’ repo’s will be disabled)

wget ftp://timburgess.net/repo/clearos/5.2/os/timb-release-1-0.noarch.rpm rpm -Kv timb-release-1-0.noarch.rpm rpm -Uvh timb-release-1-0.noarch.rpm

ref http://www.clearfoundation.com/docs/howtos/adding_tim_s_repo

yum --enablerepo=timb install kmod-atl1e

ref http://www.clearfoundation.com/component/option,com_kunena/Itemid,232/catid,28/func,view/id,24438/limit,10/limitstart,50/

last you need to edit the /etc/modprobe.conf
it need to contain an alias for every network card in my case I have a TP-link installed as well so

alias eth0 r8169 alias eth1 atl1e

if you fail to get this to work ifconfig -a will have a odd tmp interface.

Installing NX Server (neatx-server) on Ubuntu 11.10 Oneiric

2012-01-23T22:41:32+00:00

Here is a well laid out explanation of how to do it: http://blog.philippklaus.de/2011/11/install-nx-server-neatx-on-ubuntu-11-10/ I am a bit disappointed with the result though. I don’t seem to be able to connect and disconnect cleanly. The neatx server leaves sessions behind and then tries to re-attach to them causing an error.

Telstra provides a costly service. There isn’t enough competition to get the prices down especially in a regional area. They do have the best coverage on the mobile network though and it would be unfair not to mention our low population and enormous cabling distances to provide some sort of counter-point to the first sentence.

Autono-mow – The DIY Autonomous Lawnmower – Day 1

2012-01-08T07:30:15+00:00

Work began today on my Autonomous robotic lawnmower.

The intention is that this robot should be able to mow the lawn in my back yard without major human interaction.

The mechanical works began today with an old Rover mower having the back wheels removed and new rear drive wheel added. Driven by EK Ford Falcon windscreen wiper motors.

The Mower for Modification

The video below shows only one wheel added and being powered by a 12v sealed lead acid motorbike battery. As can be seen in the video the battery is connected directly to the motor terminals.
