LMD 1.4.1: Delivering on your requests
Nov 20th
The release of LMD 1.4.1 is now live and with it comes a few new features. In this small update, I have tried to deliver on on a couple of common feature requests from users which were in-line with my development goals. That said, right to it…
The biggest change has come in the form of what has been dubbed public mode scanning. This is where non-root users can execute malware scans. For this to work, a new quarantine, session and temporary path directory tree needed to be created that users had write access under. This presented some challenges and in the More >
Linux Malware Detect: 2 Years Strong
Oct 6th
As cliche as it sounds, where has the time gone? Today we celebrate two years of Linux Malware Detect, open-source (web) malware detection.
The project has seen allot of change since the first release. What was initially started as an internal project to deal with a large increase in malware activity at my job, a mid-sized web hosting company, quickly grew into a larger, established, project that proved useful for the hosting community at large. I spent nearly three months collecting malware to form the base of the initial signature set, developing the program logic and engaging people in WHT & More >

I will try cover some of the highlights of this release for those with the appetite for it, here goes…
One of the more exciting changes is that Clam Anti-Virus is now supported as More >
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 >
LMD 1.3.9r1: Hexdepth Bug
Apr 3rd
I have put up a revision to the 1.3.9 release of LMD that fixes a hexdepth bug in which malware greater than 65Kbytes would cause an error in the internal hexstring.pl script and be considered clean on the stage2 hex scanning of malware. This would mean that unless malware had a MD5 signature for it to be caught on stage1 scan, it would not be picked up by a corresponding HEX rule in stage2 scan if its file size was greater than 65Kbyte, due to the bug.
In addition, I have made the decision in this revision to enable release update More >
On The Road: Network Disaster & Dual Public-Private Network
Mar 24th
As an administrator within a mid-sized organization, you can find yourself wearing many occupational hats, which becomes only second nature after awhile. One of these many hats I wear, is that of lead network administrator, which is something I am particularly fond of… I love networking and everything about it (except maybe wiring racks and crimping ).
Today many data center networks are designed in a dual public-private network setup, which simply put is you have a private network parallel to your public network — effectively you run two cat6 copper runs to all racks and servers. The traditional concept behind More >
