Blog July 14 Day 9
Maurice discussed security. This is a vital topic and was well connected to our visit to Blackbridge yesterday. The need for backups and redundancy is a very important as we need access to our data in a timely fashion. I was surprised to hear about the lack of redundancy of the supernet in all areas of the province, rather than the core. I liked the idea of different levels of saving daily/weekly/monthly that Morris had shown, as it would be an idea I will implement on our SIS.
Lyle did a further discussion on virtual servers. These are a more robust machine than a regular server, but can run more than one server. It usually has multiple processors and higher levels of RAM. The virtual server takes advantage of the downtime in the processor to run a different application. One benefit of a virtual machine is that you don’t use a lot of power for a variety of servers.
He also ran a program packet sniffer to allow visualizing traffic from the internet across a server. We were able to see traffic coming across the core switch as he had programmed port 8 to be read. We could not log on one of the other networks servers and see the traffic. We did shut down all our switches for Morris presentation due to noise, just before Lyles presentation, so that may have caused default settings to revert.

We had the opportunity to run a virtual red hat linux machine on one of our Windows 7 enterprise workstation.
We had to log onto the s drive on the server .Our instructor installed the requirements on the server. as they are free I will run this virtual machine on my computer at home.

We had to run the setup_magic disc . We opened it up and it ran on our computer. There was a icon on the bottom right with a disc. We clicked on this and it allowed us to enable the virtual DVD, in this case the E drive.
Install the operating system on your virtual machine. We had to run the CentOS-6.0-i386-bin-DVD via the virtual DVD. This went through it’s processes. There was a few times that we would loose mouse control. We would select the CTRL on the right side of the keyboard. This was something I have never done before.
Once this program was done we were able to run the VirtualBox-4.0.10-72479-Win program from the s drive. This program was very simple to run . Just follow the prompts. The password we chose was admin5769. The only error was the first time I ran the default setting instead of the desktop version, and I gor a line command instead of the GUI for this OS. Once I reran it with this selection of Desktop, it worked fine and we got the GUI This setup also put the Oracle VM virtual box Manager, where we could see the preview of what the redhat os was running,
The login required a password which was admin5769 for the user js
The last install was the Oracle_VM_VirtualBox_Extension_Pack-4. This gave us full features such as the full screen. We initially could not get the Firefox browser to open on the virtual machine. We had to go to the Virtualbox manager/machine/settings/network/adapter 1 and check the enable box.

This allowed the network card to operate, as initially it had not, and thus we were able to open the Internet using Firefox. as the picture at the top of this blog proves.
A virtual machine setup and operational, who would have thought.
Now I canclaim to be a real geek as I can say I know how to play in Linux.
Bring on the Voip Phone Lyle !!!!!!!!
