Removing Old Kernels In Ubuntu

I inevitably run into this and always forget how to do it. Dropping it out here so I can always find it. First of all, I’ve always referred back to a few spots to get me started, but they don’t quite get me all the way there. Here’s two spots that always get me started. […]

Create Zabbix Host Items from MIB

Writing this post because I didn’t really find a lot of great full walk-throughs for doing this when I had to today. Basically what I’m doing here is I’ve got a relatively uncommon device (ControlByWeb PLC) that I’m looking to monitor via SNMP with Zabbix. In the past I think I’ve used some SNMP walk […]

Ubuntu Partition/MBR Repair

A couple of weeks ago I had a power failure in my place and unfortunately my vSphere cluster is not on UPS power (got it hooked up to 220v and haven’t had a chance to purchase a 220v UPS yet). Most of my machines came back fine but one of my machines wouldn’t boot…at all. […]

Setting Up PlexRequests Using Meteor Up

Ok, starting from the beginning. A good buddy of mine recently […]

Error Upgrading Splunk 6.1 to 6.3.1

While following the phenomenal upgrade process here: http://www.redelijkheid.com/blog/2011/11/10/upgrading-splunk-on-ubuntu-linux.html I ran into an odd issue […]

Extend Volume on Amazon EC2 Instance

This one is pretty straightforward, but it is a nice little one that I might have to come back to at some point.  There is a really simple workflow for this: 1. Shutdown the EC2 instance 2. Create a snapshot of the volume that you want to expand 3. Create a new volume from the […]

Amazon Glacier Backup of Linux Server

If you’re looking for cheap offsite backup storage and are ok waiting up to 24 hours for the ability to restore these backups, Amazon Glacier seems to be the main contender out there. At .01 per GB per month and no cost for storing or deleting backups (they do nick you on restores), it’s hard […]
