Install OS X Yosemite via Bootable USB Flash Drive

How to Create Bootable USB Flash Drive

First, create bootable USB flash drive. Here is how you do it, courtesy of Redmond Pie:

• Plug in your USB drive into the computer and open Disk Utility (in Applications).
• Select the USB drive from the left sidebar and click on Erase tab.
• Choose Mac OS Extended (Journaled) in the format box and let the name be Untitled (default).
• Now click on Erase button and wait until the format process completes.
• Then choose Partition tab and select 1 Partition from Partition Layout dropdown menu. Click on Option and ensure GUID Partition Table is selected as the partition scheme, with its name set to Untitled.
• After downloading the OS X 10.10 Yosemite instakker from the Mac App Store, just quit the installer and set the downloaded file's name to Install OS X Yosemite.app.
• Launch the Terminal app (in Applications/Utilities) and type or paste the following command in, and then hit Enter:

sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Yosemite.app --nointeraction

Note: The code above has missing double dashes in the quotes. Please replace a single "-" with "- -" when you enter the above command line in the terminal.

This will create the bootable USB flash drive. This takes between 10-20 minutes. Do not interrupt the Terminal or eject the flash drive during the process. Once the process completes, you will see the message "Copy Complete. Done."
The OS X Yosemite bootable USB flash drive will be ready for use and you can start the clean installation process.

How to Clean Install OS X Yosemite on Your Mac

Step 1: Ensure the bootable USB flash drive is plugged into your Mac and restart the computer. As soon as the start-up chime plays, press the Option key (Alt).

Step 2: Choose the USB drive on the start-up drive selection screen and hit Enter/Return on the keyboard.

Step 3: Wait until the Yosemite installer appears on screen. This could take a few seconds or minutes.

Step 4: Click on Disk Utility and then hit Continue.

Step 5: Click on Macintosh HD from the left hand-side pane and then hit Erase tab on the top-right portion of the window. Leave all the settings at their default values and then hit Erase button at the bottom right. This will wipe all files stored on your startup hard drive.

no option to add affinity group to virtual network azure

This option have intentionally been replaced by the Region/Location as you said.
Regional Virtual Networks are supposed to be more appropriate than affinity groups.

Obviously, if you still want to bring back the Affinity group, then try this:

Create a Virtual Network from the Management Portal Download the Virtual Network Configuration File

Edit the appropriate file section to get

VirtualNetworkSitename="VNetDemo" AffinityGroup="VNetDemoAG"

instead of

VirtualNetworkSitename="VNetUSWest" Location="West US"

Then, delete the previously created virtual network and import your file in the management portal to recreate the network with your defined settings

Boot-Repair Ubuntu

Getting Boot-Repair
1st option : get a disk including Boot-Repair
The easiest way to use Boot-Repair is to create a disk containing the tool (eg Boot-Repair-Disk, a disk starting Boot-Repair automatically), and boot on it.

Remark : it is recommended to install the ISO on a live-USB (eg via UnetBootin or LiliUSB or Universal USB Installer). Do not burn it on a DVD if your computer has Windows8 pre-installed, or if your boot is in EFI mode.

2nd option : install Boot-Repair in Ubuntu
- either from an Ubuntu live-session (boot your computer on a Ubuntu live-CD or live-USB then choose "Try Ubuntu") or from your installed Ubuntu session (if you can access it)

- connect to the Internet

- open a new Terminal, then type the following commands (press Enter after each line):


sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
Using Boot-Repair
Recommended repair
launch Boot-Repair from either :
the Dash (the Ubuntu logo at the top-left of the screen)
or by typing 'boot-repair' in a terminal
Then click the "Recommended repair" button. When repair is finished, note the URL (paste.ubuntu.com/XXXXX) that appeared on a paper, then reboot and check if you recovered access to your OSs.

If the repair did not succeed, indicate the URL to people who help you by email or forum.

Configure Port Forwarding using Virtual Host to access devices on Internal network Cyberoam firewall

Scenario

Throughout the article we will use the network parameters shown in the network diagram given below. Outbound traffic from LAN and DMZ is allowed while inbound traffic is restricted. The Web Server is hosted in the DMZ.

Network components	External IP address (Public)	IP address (Internal)
Web server	1.1.1.1	192.168.1.2 (Mapped)

For virtual hosts:

External IP: IP address through which Internet user’s access internal server.

Mapped IP: IP address bound to the internal server.

Configuring Ruckus ZoneDirector for Wireless Guest Access

I recently converted my standalone Ruckus Access Point to controller based mode. The specific model of controller I am using is the ZoneDirector 1100 running software version 9.5.1.0s I wanted to expand the capabilities of my wireless network and allow temporary Wireless Guest access. The process was quite intuitive and I found the ZoneDirector interface easy to navigate. This article will walk through the process I used for configuring a Wireless Guest network using the Ruckus ZoneDirector.

ZoneDirector Interface

The ZoneDirector interface is fairly simple. After connecting to the web interface need to login as administrator. Once login can see few tabs on top like Dashboard, Monitor, Configure, and Administrator.  After choosing Configure tab, a vertical menu appears on the left side of the page. Most of the configuration found within the WLANs, Users and Guest Access tabs.

Configuring Guest Access

The Guest Access option on the left side vertical menu provides access to the parameters that will control the behavior seen right after a guest connects to the wireless network. The first option I chose forces users of the guest network to authenticate. As shown below, I have also enabled a feature that allows the creation of “shared” credentials and checked the option to display a legal disclaimer.

All other parameters on this page were left to their default settings. I do want to mention the restricted subnet section allows for traffic filters to be configured. By default, communications to all private addresses is filtered.

Configuring the Guest WLAN

After configuring the appropriate Guest Access parameters, the next step involved creating a WLAN (which is bound to an SSID) to enable as a “Guest” network. The one I created is called PGUEST. This was done by clicking WLAN and Create New. Then I simply filled out the applicable information. Under Type, I changed the radio button to Guest Access. I left Wireless Client Isolation set to Full to provide protection between wireless clients.

Worth noting, I left Authentication set to open and Encryption Method set to None. This does not provide any encryption to your guest users. If you have regard for the privacy of your guest users, this should be rectified by choosing a current authentication and encryption method. While this will increase the difficulty of the connection process for the users, it will further secure the wireless environment.

Create User Account for Creating Access Tokens

At this point, the only thing left is to generate some guest password tokens and test the process. A prerequisite to this is creating a local user account that will be used to request access tokens for the Guests. The default administrative account doesn’t seem to have that ability. These local user accounts are not required for the guests. I created the an account by choosing Users from the horizontal menu, then clickingCreate New.

Creating Guest Passwords

Using the newly created user account, guest passwords can be generated by pointing a browser toward the following url.

https://192.168.0.2/guestpass  (where 192.168.0. is the ZoneDirector IP Address)

After authenticating with the local user account, a web form will be presented. I created a token for a fictitious user. If more than one guest network is configured, it is important confirm that the correct one is shown. After clicking Next, the interface presents the option to view and print the instructions  and password for the guest users.

Testing Guest Network

To test, I simply connected to the PGUEST SSID. The first access to a website was properly intercepted and redirected. The redirected page prompted for the Guest Password. After entering the provided password, I was presented with the terms of use. Accepting the terms allowed me to access the Internet but restricted access to all other internal IP addresses.

PowerPoint found a problem with content in xxxx.ppt__PowerPoint can attempt to repair the presentation

Problem with Office-2010 PowerPoint-2010

I am trying to download a powerpoint file from a web tool. After downloading when I try to open the file I get the blah blah "PowerPoint can attempt to repair the presentation." When I clicked repair it gave another error message that "There was an error access the file".

After a lot of looking around I HAVE FOUND THE SOLUTION. The "Protected View" settings in PowerPoint has to be changed to be able to consider the web downloaded presentations as safe and viewable. Here is how I did it:

1. Open PowerPoint 2010 -> Click on File -> Options

2. On the side tab click on "Trust Center" -> Now click on "Trust Center Settings" which is in the right window.

3. It opens a new window "Trust Center"

4. Click on "Protected View" on the left side panel.

5. Uncheck "Enable protected view for files originating from the internet". - Click OK and OK

This should get rid of "repair my ____" error and open the ppt file.
