- Howto: Change the IP address of a Dell 4/P DRAC from the command line without rebooting the server – Normally you configure a Dell Remote Access Card (DRAC) when a server is initially commissioned. Once the card is set, administrators rarely if ever need to modify the settings. If you do need to change the settings, the server needs to be restarted so the DRAC BIOS can be modified, which obviously results in system downtime and requires a physical presence at the server console.
- bash ini parser | /var/log/ajdiaz – In some situations i like to use INI files as configuration files, as python do. But bash do not provide a parser for these files, obviously you can use a awk code or a couple of sed calls, but if you are bash-priest and do not want to use nothing more, then you can try the following obscure code:
- Jugg Monkey: VMWare HA Agent had an error – I recently had a problem with one hoste in a 3 node VMWare ESX 3. 5 cluster. For some reason, the HA Agent would not start after I applied outstanding software updates. I kept receiving "VMWare HA Agent had an error" in the alerts after the host came online. I had recently needed to change the IP address of the VMWare 3.5 ESX host, so I figured that was the root cause.

- Get your Dell Service Tag number via the Linux (or Windows) command-line – Brandon Checketts – When your server is located in a data center far away, it makes it difficult to walk over to the box and read the service tag off of it. Fortunately, the Service Tag is stored somewhere in the system BIOS, and is accessible with the ‘dmidecode’ utility.
- TCP Traffic Analyzer (Yahoo! Developer Network Blog) – You probably have questions like these about traffic on a TCP (Transmission Control Protocol) server (or client):<br />
* How many connections lasted more (or less) than X milliseconds?<br />
* How many connections needed more than N attempts to succeed?<br />
* What is the distribution of connection duration or connection throughput?<br />
* What is the distribution of connection duration or throughput for connections in which the server or client sent more than N bytes?<br />
* What specific IP addresses and ports had connections that lasted between 50 and 100 milliseconds long?<br />
You can get answers to these questions (and more) using Yahoo!'s TCP Traffic Analyzer (yconalyzer), available as an open-source project via free download.
