This is a serious bug affecting a lot of servers including Debian Wheezy. Act fast because everything is being scanned and information is being leaked right now!
The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
It’s really easy to use to bug to steal information from affected systems without having any access to it or the network. To check if your server is infected and see what information it is exposing you can use this python script: hb-test.py
To use the script, make sure you have python installed and run the following command:
Adding a additional hard disk to your workstation or server is easy and often required. Here’s we’ll step through the process of identifing the newly attached drive, prepare and mount it by referencing UUID which is a preferred method today.
If you have just added a virtual disk to a virtual machine, make sure you restart the virtual machine before mounting the new disk.
Nginx is an open source reverse proxy server, load balancer, HTTP cache, and a web server. The Nginx project started with a strong focus on high concurrency, high performance and low memory usage. Users have been moving to Nginx because of the high performance and stability and as of February 2014, Nginx is hosting around 15% of all web servers according to Netcraft’s Web Server Survey.
In this tutorial we’ll cover install and configuring Nginx, PHP (with PHP-FPM) and MySql server.

The VMware Tools package adds drivers and utilities to improve the graphical performance for different guest operating systems, including mouse tracking. The package also enables some integration between the guest and host systems, including shared folders, plug-and-play devices, clock synchronisation, and cutting-and-pasting across environments.
The Open Virtual Machine Tools (open-vm-tools) are the open source implementation of VMware Tools. They are a set of guest operating system virtualization components that enhance performance and user experience of virtual machines.
Installing open-vm-tools is very easy on wheezy, just install the package using apt-get and reboot the machine when completed.
Webmin is a web-based system configuration tool. With Webmin it’s easy to configure operating system internals, such as users, disk quotas, services or configuration files, as well as modify and control open source apps, such as the Apache HTTP Server, PHP or MySQL.
