ATA Over Ethernet: As an Alternative
Apr 4th
New technologies, new toys — Oh how I love getting my hands dirty with them. Today I am going to have a look at ATA Over Ethernet (AoE) as an alternative solution to NFS in the role of a NAS/SAN implementation. We will look at both the server side vblade setup and the client side AoE kernel module along with a practical deployment setup which includes a convenience script I developed to make vbladed slightly less of a nuisance to maintain.
First things first though, what exactly is ATA Over Ethernet? Straight off the wikipedia page, here are the important parts More >
IRSYNC & Limiting Passwordless SSH Keys
May 4th
Anyone who has ever used SSH key-pairs to access more than a couple of servers (or hundreds in my case), will tell you they are an invaluable convenience. It is a natural progression and very common usage that SSH key-pairs are coupled with other common tasks or tools, where having a pass phrase attached to the key would be counter-intuitive to the task automation. So, what do we do despite our better judgment? We create key-pairs with absolutely no pass phrase. The implications are abundantly obvious, if the private key ever gets lost or stolen, any accounts that have the More >

Mar 31st

Usually, this is not much of an issue (not that I make a habit of it) with the continuous data protection we have implemented at the data center (cdp r1soft) except that the backup server this particular client system was using had suffered a catastrophic raid failure the very night before. We have had raid arrays go bust on us before, typically very rare but it does happen… Obviously this resulted in the clients site and databases getting absolutely toasted and having only More >
