Although its name suggests perhaps even grander capabilities, Windows enthusiasts are excited over the discovery of a hidden "godMode" feature that lets users access all of the operating system's control panels from within a single folder.
To enter "godMode," one need only create a new folder and then rename the folder to the following:
Users are able to have a single place to do everything from changing the look of the mouse pointer to making a new hard-drive partition.
The trick is also said to works with Windows Vista, Windows 7 and Windows 8.
Important: Critical OpenSSL security exploit
A serious vulnerability has been discovered in OpenSSL (the most popular SSL module used on Linux based servers). This exploit allows a third party to steal information that would otherwise be secured and encrypted with the SSL/TLS protocol.
If you have a virtual server (VPS) or dedicated server you urgently need to apply the latest OpenSSL patches. Instructions below -
- Login to WebHostManager
- Go to cPanel in the left hand menu
- Click Upgrade to Latest Version
- Follow upgrade instructions
- Go to Software in the left hand menu
- Click Update System Software
- Follow upgrade instructions
- Login to the Plesk Control Panel
- Go to to Settings
- Run the Plesk Updater
For the CentOS operating system:
- SSH in as root
- Run the command ‘yum update’ from the command line
- Yum will update the at-risk packages
For Ubuntu or Debian operating system:
- SSH in as root
- Run the command ‘apt-get update && apt-get upgrade’
If you need assistance patching your systems consider contacting a technical services company such as Aorta Consulting.
Sysdig is an open source Linux system troubleshooting tool which allows you to capture system state and activity from a running Linux instance, then save, filter and analyze it. It includes strace, tcpdump, lsof and a number of other utilities all compiled into one Swiss-army style tool.
Sysdig is designed to simplify system level troubleshooting, in-particular distributed, virtualized and cloud-based environments. Sysdig captures system calls and other system level events using a linux kernel facility called tracepoints, which means much less overhead than strace. It then “packetizes” this information, so that you can save it into trace files and filter it, a bit like you would do with tcpdump. This makes it very flexible to explore what processes are doing.
