Data Wiping Software

DBAN is free erasure software designed for the home user. It automatically deletes the contents of any hard disk that it can detect. This method prevents identity theft before recycling a computer. DBAN is also a commonly used solution to remove viruses and spyware from Microsoft Windows installations.

• DBAN users should be aware of some product limitations, including:
• No guarantee of data removal (e.g. DBAN does not detect or securely erase SSDs)
• No audit-ready reporting for regulatory compliance
• Limited hardware support (e.g. no RAID dismantling)
• No customer support or regular software updates

A very good Operating System for wiping out hard disk....

Check it out at below link...

Cisco NX-OS and Cisco IOS Comparison

• When you first log in to NX-OS, you go directly into EXEC mode
• NX-OS has a setup utility that enables a user to specify the system defaults, perform basic configuration, and apply a predefined Control Plane Policing (CoPP) security policy
• NX-OS uses a feature-based license model. This enables flexibility in licensing for uses in different areas of the network in which not all features are required
• NX-OS has the capability to enable and disable features such as OSPF, BGP, and so on via the feature configuration command. Configuration and verification commands are not available until you enable the specific feature
• Interfaces are labeled in the configuration as Ethernet. There aren’t any speed designations in the interface name. Interface speed is dynamically learned and reflected in the appropriate show commands and interface metrics
• Secure Shell version 2 (SSHv2) is enabled by default. (Telnet is disabled by default.)
• The default login administrator user is predefined as admin; a password must be specified when the system is first powered up. With NX-OS, you must enter a username and password; you cannot disable the username and password login
• The default Spanning Tree mode in NX-OS is Rapid-PVST+
• Caution In NX-OS, you must enable features such as OSPF, BGP, and CTS (Cisco Trust Sec). If you remove a feature via the no feature command, all relevant commands related to that feature are removed from the running configuration

Why We Can't Create Con Folder in Windows ?

A Reason Behind Why We Can't Create Specific Folders in Windows

Most of us are aware, we can't create a folder with name "Con" in windows and all most many of us don't know the reason.

Well I present you the reason and list of keywords which we can't use in windows to create folders or file.

Reason:

We cannot create folder with con, aux, nul because these are reserved keywords used by DOS. So if we were allowed to create such folders than there will be an ambiguity, in where to write data when the data is supposed to; go to the specified devices.

 

Keywords and Their corresponding Functions:

Reserved Keywords	Function
CON	Keyboard and Display
PRN	System list device, usually a parellel port
AUX	Auxiliary Device,usually a serial port
NUL	Bit-Bucket Device
A:-Z:	Drive Letter
COM1	First Serial communications port
COM2	Second Serial communications port
COM3	Third Serial communications port
COM4	Fourth Serial communications port
LPT1	First Parallel printer port
LPT2	second Parallel printer port
LPT3	Third Parallel printer port
