- Resolve Hardware Status Alert SEL_FULLNESS | Brian Ragazzi – […] I noticed an alert on two UCS B250M2 hosts in the vSphere Client. The alert Name was “Status of other host hardware objects”. This isn’t helpful. To get more information, you have to navigate to the Hardware Status tab of the host properties. Here I saw more information about the alert. It’s cryptically named “System Board 0 SEL_FULLNESS”. […]
- Network Stack: Cisco ASA Packet Capture – […] The ASA platform has fantastic built-in packet capture capabilities which can come in very handy for troubleshooting issues. I will be demonstrating some of the capabilities using an ASA 5505 running version 9.0(1).Performing a packet capture is done using the capture command from privileged exec mode. […][ Fantastic… I won’t say that ]
- Multistage environments with Ansible – Ross Tuck – Ansible has excellent documentation but one thing I was confused about was the best way to store the configuration for multistage projects: say, different passwords for dev, staging, production. This isn’t really covered in the ansible-examples repo because it’s specific to your project and while the documentation has recommendations, it doesn’t spell it out completely (which I need since I’m an idiot).

- vim modeline – Tips and Tricks – ph3nix.Net – Generally you either love or hate Vim. It boils down to a matter of personal preference. However love or hate you have to admit it is extremely powerful for a command line, text only file editor. For those who love it – or just have to make use of it on a regular basis, the Vim modeline feature is a very useful and powerful way of customizing the visual and editing preferences as well as several other options on a file by file basis.

These are my links for 8 set 2014 through 9 set 2014:
- How to write udev rules – Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded.
- Persistent iSCSI LUN Device Name – jablonskis – […] I spent a bit of time figuring out how to get this achieved, so thought it is worth noting for the future reference. I will try to make this quick assuming you have knowledge about iSCSI software initiators in Linux[…]

- NSA-proof your e-mail in 2 hours | Sealed Abstract – You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. The way that e-mail was originally designed to work. We’ve all just forgotten because, you know, webapps-n-stuff. It’s a lot of work, mkay, and I’m a lazy software developer.
