  • “Reverse Engineering for Beginners” free book
  • 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 ]
  • Sanesecurity ClamAV Malware, Phishing, and Spam Signatures – Sanesecurity produces add-ons signatures to help improve the ClamAV detection rate on Zero-Day malware and even on Zero-Hour malware. Since 2006 we have provided professional quality ClamAV signatures to protect against the following email types: Macro malware, Zip malware, Rar malware, Javascript malware, 7z malware, Phishing, Spear phishing and other types of common emailed malware and spam. Sanesecurity 3rd Party ClamAV signatures can also help prevent TeslaCrypt, Cryptowall, Cryptolocker and other ransomware, who’s source usually starts as a malicious email.
  • 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).

  • Checking UCS Settings from the UCS Manager CLI – I was recently using the UCS Manager CLI and I wanted to share my findings. You can SSH to the UCSM (UCS Manager) and then run commands to figure out information about your hardware configuration. Whenever working with Cisco UCS Servers, the first thing we need to figure out is how Service Profiles are used in a UCS Environment.
  • Add a VLAN to a UCS blade via the CLI | VirtuallyMikeBrown – What I really wanted to do was add a couple existing VLANs to the vNIC of an ESXi host on a blade (so I could vMotion some stuff around). Of course, with the GUI, it’s a few clicks. Without the GUI (and not knowing where to go in the CLI), I was at a bit of a loss.The UCS CLI guide wasn’t helpful as it was more for managing the hardware or upstream configs – not so much for what would seem like a task made for UCSM. So to get on with it, let me share the quick config for adding VLANs to vNICs.

  • Zsoldier’s Tech Blog: Add Portgroups/VLANs to vmware standard switches via PowerCLI – Wrote a simple little script to insert a portgroup into a targeted vSwitch of all VM hosts in a targeted cluster. This is not an issue if you use distributed vSwitches.

  • Hardening Framework – […] Server hardening is a well-known topic with many guides out in the wild. Why this project? At Deutsche Telekom we need to manage thousands of servers for customers and ourselves. All servers need to be configured properly and maintained, which is difficult and time-consuming to get right. To answer these needs for security, compliance, and maintainability, we decided to launch this project as a common ground for requirements and their fulfillment.[…]

  • ansiblecookbook.com – This books should become a reference for how doing cool things in your daily business with Ansible, things you can not find in the official docs.
  • Ansible Cheat Sheet | Wall-Skills.com – Ansible is the cool, new kid on the block that is IT automation. So, just in case you need an Ansible Cheat Sheet, we’ve got you covered
  • zorangagic/awsinfo – Daily Inventory of all AWS resources in excel format
  • High availability clustering on AWS | Zoran’s Blog – How do we keep legacy applications highly available on AWS? I have already written about this previously and there are many good alternatives with the upcoming Cloudwatch instance recovery the easiest to implement. Yet Cloudwatch instance recovery or autoscaling group with min=1,max=1 still requires failure to be detected (1-2 mins) and new instance to be booted up (2-3 mins). If the application can not tolerate outage of 3-5 minutes then high availability clustering may be a good alternative
  • jordansissel/pleaserun: An attempt to abstract this “init” script madness. – Pleaserun is a tool to generate startup scripts for the wasteland of sorrow that is process launchers.
