Day 0000 1010

VOIP, Packet Sniffing and New Media Center Tour

QOS - Quality of Serivce
Qualtiy of Service needs to be enable on the switch. This allows gold traffic to go through relatively uninterupted. The internet is not QOS enabled. This is seen in the buffering that occurs when downloading from media sites like YouTube.

The exercise that was completed today used VOIP on an internal network. A Private Branch Exchange (PBX) server was setup on Lyle's server with the IP of 192.168.181.251. Extensions were assigned to the different groups.

The first step was to enable QOS on the switch.
Commands:
>qos enable
>qos trust port
>qos apply
>write memory
>copy working certified



X-Lite
X-Lite is a VOIP softphone application that we used to connect within our network. Setting up the software included entering the IP of the PBX server, our extension and turning on the QOS option. The QOS option was set in the preference windows. This was set to 46. The quality of service is assigned a number between 0 and 48.


Connections were made to other members in the class by dialing their extension set up by Lyle.

Wireshark
Wireshark is an etwork protocol analyzer that we used to check quality of service while calling. The "packet sniff" was carried out while calling someone on X-Lite. The captured data was searched for the dscp hexidecimal equivalent of 46 which is 0x2e. This indicated that the VOIP traffic was being recognized and going through as Gold traffic.



School Tour
The class ended with a tour of the New Media Center in Chinook High School. It was a fascinating and impressive tour. One aspect that struck me was how the vendors worked with the SD's people to bring about the project. This has created a group of individuals with a greater investment and ownership in the project. This should greatly facilitate the implementation of programs for students that optimizes the facility. It is important to remember that programs are people. It is the people with the vision, knowledge, ability and expertise that will create the impact on students and learning. This is the desired end of all the work and investment. It is not about having a trophy and the bragging rights.

Day 0000 1001

Activities:
1. Security
2. Virtual operating system

Content:
Setting up a Virtual Operating System

1. Install Magic Disc–This is a virtual disk program that can be downloaded free from the Internet. This is needed to open up installation applications in ISO form.
Lyle had placed these programs in the shared folder on server. The software was installed on the workstation Using the administrator account.


2. VirtualBox was installed next. The default installation location was selected. When the security questions came up Install was selected.


3. Installation of Red Hat virtual book.

A new virtual machine was created. It was given the name Red Hat. This automatically selected the operating system of Linux with the version.

The basic memory was increased to 1024 MB. Next, the option–create new hard disk–in the Virtual Hard Disk was selected. The hard disk storage type was–Dynamically expanding storage.

Size of the virtual hard disk The was increased to 20 GB in the Virtual Disk Location and Size window.

Following this, the operating system installation file was mapped to virtual disk drive, in our case drive E. Next was selected and the operating system CentOS installation window came up.

Install or upgrade and existing system was selected.


When given the option we chose to skip the testing of the media.

Once we passed language option, we were given the choice of the type of devices our installation would involve. Basic Storage Devices was chosen. A warning came up “error processing drive”. The option chosen was Reinitialize all. The password we used was the default password for the system.

In the next window the type of installation was Replace Existing Linux System. Minimal installation was selected in the next window.

After the installation is complete, a network connection was created. A browser window was open and the connection was made to the Internet.

Day 0000 1000 Part 1

Activities:
1. Install printer on the network
2. Create custom start menu

1. Installing Network Printer
Installation of the Xerox printer is the final process that needs to be documented. However, we still need to create a common start menu for the users in our network.

Begin by downloading the drivers for the specific printer that you have. Make sure that you download the Windows Server 2008 drivers. It is good to standardize which drivers you use (ie. postscript drivers) and load these on all your servers that will be accessing the printer. If there are more than one type of driver, the printer must reload the drivers to print the different formatted print job. We went with postscript drivers.
The next step is to go into the Printers window in the control panel. Add a printer.





Add a local printer and create a new port: Standard TCP/IP Port

you will then be asked to enter in the IP address of the new printer.


You will then be asked to install the drivers for the new printer. Since you already have installed the printer drivers on your computer, they will be located in the driver window.








Next, In the print manager, select Printers in the network. Deploy the printer with the group policy.




Locate the group policy that you wish to play with.
