All downloads are gone :(

Thanks to a catastrophic failure during migration from a private server to a shared server, all the site downloads are gone :( the blogs posts, comments etc basically everything that was on the database we were able to recover from a db backup, but anything on the filesystem is gone. So all the virtual machine images are gone as well so no more virtual machine downloads :(

I will try to spin up a few of the latest gentoo and slackware versions that I have skipped earlier on  in the next few weeks and hopefully we will have some downloads then.

Sorry for the inconvenience, if you came here looking for quick access to some linux virtual images .

Improve linux raid rebuild/resync speed

I have a small :) NAS box with 6 x 1TB HDD in RAID 6 and 4 x 500GB HDD in RAID 5. Recently thanks to the arrival of my baby girl and a HD handy cam, I was running out of space fast on the array and so when when I saw a decent deal for 1TB drives in NewEgg I picked up couple to add to the RAID 6 volume.

Growing a raid array in linux using mdadm is easy. I made sure I used fdisk to create single large partition on the drive and mark the partition type fd (Linux raid autodetect) prior to adding it to the array.

Device Boot Start End Blocks Id System
/dev/sdm1 1 121601 976760001 fd Linux raid autodetect

Adding the drives to the raid is straightforward
mdadm --add /dev/md1 /dev/sdl1
mdadm --add /dev/md1 /dev/sdm1

PXE boot VMware ESXi 4.1 and Manual Install

an awesome new feature in the just released ESXi 4.1 is the ability to do PXE boot and script the install using a kick-start script. If you looking for information on how to do this see here at billhill’s post.

http://communities.vmware.com/blogs/vmwareinsmb/2010/07/13/esxi-41-scripted-installation-via-pxe-and-kickstart

However while adding that feature VMware seems have slightly broken the PXE boot, but manual install ability of ESXi. This is useful if you have lights-out lab and want to use the local pxe server instead of those virtual media options but also want to customize the install options as the lab servers do not have standardized components and hardware and may other issues.

Refer to the above link for overall PXE/dhcp/tftp install steps. I plan only to document what’s different for a manual install.

setting up http proxy for cli

Okay, I have to google this information every-time I need it, to so am going to blog it, so that I know exactly where to look for it :)

Setting up a proxy from the GUI on you browser or system does not always work for command line utilities like apt-get, yum, wget or customer bash scripts etc…

So here is how to setup proxy for CLI from CLI, assuming your proxy server is proxy.example.com (IP 192.168.2.252) and port 3128.
export http_proxy='http://proxy.example.com:port/'

OR
export http_proxy='http://192.168.2.252:3128/'

Installing Silverlight 3 on Hackintosh

Okay I have always wanted to own a Mac Pro and that wish only grew more after I bought my Mac Book and the Mini for HTPC duties. I like the OS X interface and recently bought Snow Leopard Family pack to upgrade my laptop and mini and was wondering what to do with my Dell Inspiron 530s (the only windows box in the house, ohh btw I do like Windows 7 and is really the best Windows OS Yet ) and decided to dual boot it with OS X.

The hackintosh installation was a bit round about as I had install Leopard first and then use that install Snow Leopard and then update the boot loader to Chameleon rc3 and fix the boot order from the windows with easybcd 2.0 beta. That story is for latter.

Now coming back to the title of this post after I got the setup up and running, I was trying out all my usual apps and when I tried Instant Watch from Netflix, i trt wanted to install Silverlight 3.0. I download the dmg ran the install it said I was running a Power PC and the install failed. I “googled it” and found that the installer is checking for the PC type and is parsing it wrong. So here is the fix.
