Mysql physical database location on WIndows

I work with Linux, but also have to work with Windows, because most commercial applications are in Windows and the manufacturers will not switch to Linux.

There are already commercial applications that are already adopting MySQL instead of Microsoft SQL Server.

And sometimes is not where the data files are, because they use the built instead of the default MySQL installation.

Just need to find the file named "my.ini", this file contains the location of the database.

Why is it useful?

• To delete duplicate files, when going from MySQL to local MySQL for reasons of bugs and new releases. 
• To make backups with Cobian Backup, which is free and the manufacturer is selling the source code.

Citrix XenServer - XenServer Tools not installed error fix

I am implementing a project that consists of installing a server with Windows Server 2012 Standart 64 bit . 
So far so good , to save money with fixed servers , will be used virtualization with Citrix XenServer 6.2.0 that is now free , thanks Citrix .

Citrix XenServer  is one of the best virtualization tools, because they do not consume too much memory and hard disk space . For those working in Unix / Linux is a breakthrough in configurations terminal via ssh .

I had no problem to install and create virtual machines , but I had a problem that the management platform always said that the VM did not have XenServer Tools installed .

The problem is that they had already installed .

I'm using XenServer management tool that works in 32-bit (x86), so I thought reinstalling first x64 driver, citrixvssx64.msi and citrixguestx64.msi, then installwizzard.msi in the VM.

And voila, the error that XenServer Tools was not installed is resolved. 

In another virtual machine had to uninstall the XenServer Tools, update Windows by Windows Update, Installing XenServer Tools x86 manually and then run the procedure for automatic installation of XenServer Tools.

And everything is working as it should.

Students learn the four basic elements of Linux: toolchain, boot loader, kernel and user space.

5.Introduction to Linux at the University of South Carolina

A simple introductory tutorial of slides in PDF format, this course material shares basic information about what Linux is, the different versions - or distributions - available, and how to use it. Files, folders, pages, commands and writing script are some of the topics and tools this course covers.

6. The Linux Effect: 20th Anniversary at The Open University

Offered as an online podcast training, the Linux Effect offers information on the Linux operating system and how it's advanced through the years. Students learn the origin of Linux, how Linux is used in our daily lives and the connection between Linux and cloud computing. Students need a PDF viewer, such as Adobe Reader, to complete this course.

7. LPI Exam 201 Prep: Linux Kernel at IBM

In this free tutorial series, users prepare for the Linux Professional Institute Intermediate Level Administration (LPIC-2) Exam 201.

29C3 Cisco Phones Easy Hack

Hacking Cisco Phones

 Just because you are paranoid doesn't mean your phone isn't listening to everything you say

We discuss a set of 0-day kernel vulnerabilities in CNU (Cisco Native Unix), the operating system that powers all Cisco TNP IP phones. We demonstrate the reliable exploitation of all Cisco TNP phones via multiple vulnerabilities found in the CNU kernel. We demonstrate practical covert surveillance using constant, stealthy exfiltration of microphone data via a number of covert channels. We also demonstrate the worm-like propagation of our CNU malware, which can quickly compromise all vulnerable Cisco phones on the network. We discuss the feasibility of our attacks given physical access, internal network access and remote access across the internet. Lastly, we built on last year's presentation by discussing the feasibility of exploiting Cisco phones from compromised HP printers and vice versa.


Cisco PSIRT has assigned CVE Identifier CVE-2012-5445 to this issue.

IP Cisco Phones:

• Cisco Unified IP Phone 7975G
• Cisco Unified IP Phone 7971G-GE
• Cisco Unified IP Phone 7970G
• Cisco Unified IP Phone 7965G
• Cisco Unified IP Phone 7962G
• Cisco Unified IP Phone 7961G
• Cisco Unified IP Phone 7961G-GE
• Cisco Unified IP Phone 7945G
• Cisco Unified IP Phone 7942G
• Cisco Unified IP Phone 7941G
• Cisco Unified IP Phone 7941G-GE
• Cisco Unified IP Phone 7931G
• Cisco Unified IP Phone 7911G
• Cisco Unified IP Phone 7906

<Begin RNE Text>
Symptoms: Cisco Unified IP Phone 7900 series devices also referred to as Cisco TNP Phones contain an input validation vulnerability. A local, authenticated attacker with the ability to place a malicious binary on the phone could leverage this issue to elevate their privileges or take complete control of the device.
The issue is due to a failure to properly validate certain system calls made to the kernel of the device. This failure could allow the attacker to overwrite arbitrary portions of user or kernel space memory.
The following Cisco Unified IP Phone devices are affected: Cisco Unified IP Phone 7975G Cisco Unified IP Phone 7971G-GE Cisco Unified IP Phone 7970G Cisco Unified IP Phone 7965G Cisco Unified IP Phone 7962G Cisco Unified IP Phone 7961G Cisco Unified IP Phone 7961G-GE Cisco Unified IP Phone 7945G Cisco Unified IP Phone 7942G Cisco Unified IP Phone 7941G Cisco Unified IP Phone 7941G-GE Cisco Unified IP Phone 7931G Cisco Unified IP Phone 7911G Cisco Unified IP Phone 7906
The following models have reached end-of-life (EOL) status (for hardware only): Cisco Unified IP Phone 7971G-GE Cisco Unified IP Phone 7970G Cisco Unified IP Phone 7961G Cisco Unified IP Phone 7961G-GE Cisco Unified IP Phone 7941G Cisco Unified IP Phone 7941G-GE Cisco Unified IP Phone 7906
Refer to the following link to determine what product upgrade and substitution options are available: http://www.cisco.com/en/US/products/hw/phones/ps379/prodeolnotices_list.html
