Figure 2 Network diagram for MAC-based VLAN configuration


Network Requirements

l          As shown in Figure 2, GigabitEthernet 1/0/1 of Switch A and GigabitEthernet 1/0/1 of Switch B are each connected to a meeting room. Laptop 1 and Laptop 2 are used for meeting and each of them may be used in any of the two meeting rooms.
l          Laptop 1 and Laptop 2 are owned by different departments. The two departments use VLAN 100 and VLAN 200 respectively. It is required that each Laptop could access only its corresponding server regardless of the meeting room it is used in.
l          The MAC address of Laptop 1 is 000d-88f8-4e71, and that of Laptop 2 is 0014-222c-aa69.

Linux File and Directory Permissions

By
file & directory protection is a essential of any OS and Linux OS is no exception for it! These authorizations allow you to choose exactly who can access your files & directory, providing an overall improved system security. There was one of the major flaws in the older Windows operating-system where, by standard, all users can see each other people's information (Windows 95, 98, Me). For overcoming it, editions of the Windows based computer system such as NT, 2000, XP and 2003 lot more security features added. They fully support file & directory permissions, just as Linux system has since the beginning. Together, we'll now assess a directory listing from our Lab Linux system hosting server, to help us understand the information provided. a simple 'ls' command will give you the file and directory listing within a given directory, including the option  '-l' will display number of new areas that we are going to discuss here:

How to create a Hirens Boot CD 15.2 USB Disk

By
Hiren’s BootCD (HBCD) is a bootable CD that contains a set of tools that can help users to fix their computer if their system fails to boot. More specifically, HBCD contains hardware diagnostic programs, partition tools, data recovery utilities, antivirus tools and many other tools to fix your computer problems.  I write this article because I use Hiren’s BootCD frequently to troubleshoot computer problems, specially when a computer doesn’t boot anymore due to a virus attack or due to a corrupted file system. In this article you will find instructions on how to put Hiren’s BootCD on a USB flash drive (stick) in order to troubleshoot computer problems in the future.
