Wiring patch panels

Quite often simply plugging a cable from one device to another is sufficient, if however you find yourself needing to wire rooms together you may need to patch between panels and in turn wiring patch panels. Wiring generally follows a standard and can often be confusing, in order to allow rooms to be centrally administered, choose either TIA-568-A or TIA-568-B but ensure that both ends match or no connectivity will be achieved.

Strip the outer sheathing off until a little over an inch of coloured cabling is visible and position each colour over the correct spacing and apply short sharp pressure using a punch down tool or (if unavailable) a flat screw driver. Each cable should now make a conducting connection with the metal heads of the panel, snip any excess wiring once you are happy that everything works.

Domain Registration

Registering a domain is relatively simple, you choose your provider and what packages you want and then pay. The common mistake made by individuals is that they register with their home address and then think that everything is ready, this will then result in their details being searchable on the internet through a whois search. There are several courses of action to take when configuring your domain and they depend on who the internet registry company is.

Nominet

Responsible for .co.uk .wales and .cymru Top Level Domains (TLD’s), they hold and retain overall control of their domains.

Private Registration must be set on the www.nominet.org.uk website, login details can be requested even if you have never logged in before and it is a simple process. Simply Manage your details and follow the instructions.

Verisign

Responsible for .com, .gov, .mil, .org, .net, .edu, .int TLD’s and allow registrars to alter records for their domains directly.

Accessing WiFi password history – Android

How do you grab that password that you have entered in your phone so you can use your laptop on a WiFi network that you have previously joined? It’s not as hard as you might think but does need a little know how. If you have rooted your android phone then it makes life easier, I am running Cyanogen Mod but you should be able to use similar methods to get the information.

Open File Manager, if you’re not using Cyanogen Mod then Root Explorer or OI File Manager is often recommended, you should find yourself in the Internal Storage area of the file structure and might have a numeric zero visible at the top. At this point many other tutorials might baffle you but because you’re only logged in as a user you won’t be able to see the folder /data/misc/wifi/.

Enter the app settings using the menu button and select General Settings, scroll down to Advanced and Access Mode, then select Prompt User Mode. Press the file manager button at the top to give you the folder structure menu and choose Home, you will now see the /data/ folder appear and when selected you’ll be asked to authorise elevated privileges, click Yes and you’ll be whisked away to the android superuser request screen, select Remember choice for 10 minutes to save you from having to deactivate it later and select Allow. Now you are essentially an admin on the phone and can roam about unrestricted, bear this in mind and ensure you don’t play with the unknown, click /misc/ and then /wifi/ so as to see the wpa_supplicant.conf file, open this file with Editor or a text app to view its contents and see passwords and ssid’s.

There are many places to find this information, one of my references can be found here for further reading: http://zackeryfretty.com/posts/retrieve-saved-wireless-passwords-on-android

Small Business Server 2011 – Installing

Insert the CD and power on the server, ensuring that it is set to boot from CD/DVD. Allow the software to run and continue until you are presented with an “Install Windows” dialogue box, select your language settings (in my case English UK) and ensure it is correct for your keyboard before clicking Next. Another screen should now ask if you want to Install or repair, click  Install Now. Setup will then present the license terms and ask you to confirm by ticking the accept box and then clicking Next. The next stage of installation is to choose whether to upgrade or custom, in this case it is custom as it is a fresh install, you will then be asked about what disk to use, no change should be necessary so click Next. Windows will then run through its own checklist, your system specs will decide how long this takes.

Now SBS 2011 needs to be configured and asks if it should be part of a migration or clean install, in this case tick Clean Install and click Next. Provided your hardware meets the minimum standards, if however there is an issue it will tell you what needs to be resolved. Verify the time and click Next, at this point you need to choose whether to automatically detect network settings or set them manually, in this case I shall set automatic and click Next. Now select your update method, I will select the recommended setting of keep uptodate.

Following a brief process you will then be asked to enter your company details before clicking Next. Then your chosen server name and the internal domain name need to be set, bear in mind that you will not be able to change this once committed, click Next. After a short time you will be asked to enter your administrators details, note the account “Administrator” is already a provisioned account and cannot be used, click Next. A summary screen will then be presented and a final warning that domain details cannot be altered, if you are happy with what is stated click Next. Configuration will take quite some time but will eventually present a “Installation Finished” window, where any errors will then also be displayed, if there are any just click to view them and try and resolve them as you see them.

SBS 2011 is now installed, though will need some configuring to bring it up to scratch. You are now presented with the standard console where the configuration can be manipulated to fit your needs.
