How to Create User Accounts in Mac OS X

Save on Delicious

Creating User Accounts in Mac OS X

Here’s how to create an account for a user:

1. From the Apple menu, select System Preferences.
   
2. Select Users & Groups.
   
3. Click the lock and authenticate with an administrator account. The window shown below appears.
   

4. Click the + button to add a new user. The window shown below appears.
   

5. Select an account type from the New Account menu.
   
6. Enter the user's name in the Full Name field. This is used in a variety of applications, like the Mail application when a new email account is created.
   
7. Enter a username in the Account name field. Depending on how you've configured the Security preferences, the user may have to enter this username to log in to the computer.
   
8. Enter a password for the user's account in the Password and Verify fields.
   
9. Optional: Enter a hint in the Password hint field to help the user remember the password. Providing a hint is recommended, but not required.
   
10. Click Create Account.
    
11. Optional: To make the user an administrator, select the Allow user to administer this computer checkbox. Deselect this checkbox to remove administrator privileges.
    
12. Optional: To restrict the user’s access, select the Enable parental controls checkbox. Deselect this checkbox to remove the restrictions.
    
13. Repeat steps 4-12 to create an account for every user who will be using your computer.
    
14. Disable automatic login to ensure that users can access their accounts when the computer is turned on.

Understanding the Different Types of Accounts

There are five different types of accounts available in Mac OS X:

• The root user is an all-powerful account that can modify any file or setting on your Mac. This account is disabled by default and should only be used in special situations.
  
• Administrators can add new users and access all system settings. Mac OS X requires at least one user to be set as an administrator.
  
• Standard users are prevented from accessing most system settings. They can’t add new users or change the startup disk, for example.
  
• Managed users have all of the same restrictions standard users have. You can also enable parental controls for managed users.
  
• Guests are temporary users. Everything they do is erased when they log out.

Which Type of Account Should You Create?

When deciding which type of account to create for a particular user, consider the principle of least privilege: Users should only be granted enough access to perform the necessary level of work. For example, children don’t need the ability to add new users, and most users won’t need to change the startup disk.

Creating Groups of Users

You can also create groups in the User & Groups pane. Groups are collections of users who have similar permissions. If you’re an administrator at an elementary school, you could create a group for students and another for teachers - both types of users have similar or identical permissions. This is handy when you need to apply a specific set of permissions to a bunch of users at once.

How to install iPod and iPhone Driver without iTunes?

Save on Delicious

A PC requires an iPod and iPhone in order to communicate with the devices. The drivers are available as part of iTunes and are installed on the PC with the iTunes software. It is possible to install iPod and iPhone drivers without iTunes if the user does not want to install iTunes. There are iTunes alternatives which can manage the iPod or iPhone. Download alternative utilities and hardwaredevice drivers for the iPod and iPhone from the Apple site to install iPod and iPhone drivers without iTunes. 

In order to identify iPod, iPod Touch and iPhone and read their contents, your PC needs the corresponding drivers. Normally your PC is provided with the adequate drivers, when iTunes is installed. 

If, for some reasons (lack of speed, file size, old system or PC ...), you don't want to install iTunes on your system, you can get the drivers as described below:

• Download the file "iTunesSetup.exe" from the Apple webpage
• Open the file with WinRAR
• In the folder you will find some files containing "AppleMobileDeviceSupport.msi" and "QuickTimes.msi"
• Extract both files and install them on your computer

After the successful installation of both files (above all - AppleMobileDeviceSupport.msi) you can connect your iPod/ iPhone and it should be recognized correctly. You can now run and manage your iPod and iPhone without iTunes by using iTunes alternatives or iPod managers.

How to Install a Wireless Card in Linux Using Windows Drivers

Save on Delicious

Linux has come a long way with hardware support, but if you have a wireless card that still does not have native Linux drivers you might be able to get the card working with a Windows driver and ndiswrapper.

Using a Windows driver inside of Linux may also give you faster transfer rates or better encryption support depending on your wireless card.

If your wireless card is working, it is not recommended to install the Windows driver just for fun because it could cause a conflict with the native Linux driver.

Download Wireless Card Driver

The first thing you need to do is figure out what wireless card you have. There are a couple ways to do this and some involve finding the device chipset and others involve scouring through system logs.

The easiest method is to just look at the device itself, if you have an external wireless card, or search your manufactures website for what wireless card came with your computer, if you have an internal wireless card.

Once you know what wireless adapter you are trying to install, go to the manufacturer’s website to download the Windows drivers for the device.

If at all possible, you should try to download the 32-bit Windows XP drivers in .zip format rather than .exe. If you don’t have an option, select the latest Windows driver that your manufacturer provides.

Extract Wireless Driver

To extract the files, browse to the .exe or .zip file, right click on it, and select open with archive manager.

Note: Although archive manager can extract both .exe and .zip files, sometimes the files within the .exe may not work with ndiswrapper.

Click extract at the top and copy all the files to an easy to find location.

Install Ndiswrapper

Ndiswrapper is the tool that allows Linux to use Windows drivers for wireless card support.

To install it in Ubuntu go to the Software Center and search for ndisgtk.

Note: Linux Mint comes with ndiswrapper installed.

Install Windows Driver

Now that you have your wireless driver extracted and ndiswrapper installed, open Windows Wireless Drivers from the System -> Administration menu.

In the window that opens, click on install new driver and browse to where you extracted the driver.

Sometimes the .inf files will be in sub-folders inside the driver so you may need to dig around to locate the right file to use.

After you select the .inf file for your wireless card click install. It will take a couple minutes to install the driver so be patient while it works.

After the driver is installed the main window will indicate if you selected the right .inf file by telling you if the hardware is present or not. If you selected the wrong driver the first time you can try installing a different .inf file that was extracted from the driver.

If none of the .inf files work you may want to try the driver for the same card for a different version of Windows (e.g. XP, Vista, 7).

After you get the right driver installed click configure network to open Ubuntu network connections and connect to your wireless network.

How To Access Your PC remotely is using Windows Remote Desktop

Save on Delicious

Using a router is a common way to connect to the internet. It is favoured by most ISP’s who supply a free router with most broadband internet packages. Most routers have built-in hardware firewall which operates separately from Windows firewall.

The most common way to acces your PC remotely is using Windows Remote Desktop that is included with Windows XP professional, Vista, Windows 7 Ultimate. However most people find it difficult to setup correctly and are unable to connect to their PC. This article will show you exactly what to do. The router i am using is Netgear DG834G however most Netgear router’s have similar control panel so the steps below should be similar on Netgear DG834GT, DG834N and other Netgear models. If you are using a different brand router then the port forwarding steps will be different, but the port setting 3389 will be the same.

Step 1. Enable Remote Desktop from Windows Control Panel.

• If you have Windows XP then Click on Start Menu -> Control Panel -> System -> Click on Remote Tab -> Under Remote Desktop, Tick Allow users to connect remotely to this computer. Then click OK.

• If you have Windows 7 then Click on Start Menu -> Control Panel -> System and Security -> System -> Remote Settings -> Under Remote Desktop, select Allow connections from computers running any version of Remote Desktop. Then Click OK.

Step 2. Logon to your Netgear Router control panel. The defult control panel ip address for Netgear router is 192.168.0.1. So type this ip address on your browser’s address bar as shown:

http://192.168.0.1

The router will request the user id and password.

The default user id is: admin

The default password is: password

Now you will have access to the control panel. On the left side of the control panel you will have all the options listed.

Step 3. Click on Services and choose Add custom services. Fill in the box exactly as shown below.

Step 4: Click Apply. This will create a service called RemoteDesk with the port 3389 as shown:

Step 5: Click on Firewall Rules and click Add under the Inbound Services. Choose all the options shown on the image below. Please note that the Send to Lan Server ip address will be different on your computer. You need to choose a fixed ip address for your computer as its most likely set to dynamic ip address which changes all the time.

Once you fixed your ip address please type it in the box and click Apply.

Step 6: Your firewall rules will now be applied and you will get a page similar to below:

Finally click on Apply at the bottom of the page and the firewall rules will take effect.

You should now be able to connect to your PC using Windows Remote Desktop.

How To Troubleshooting Common problems,While Assembling a PC

Save on Delicious

Below is a list of common problems experienced while assembling a PC.

1: The PC does not boot, the power and HDD LED does not come on, there is no display on monitor.

Solution: Check that your main power cable is plugged into the ATX power supply. Make sure you have connected the ATX power connector to the motherboard. Check if the cable for the power switch at front of the PC is connected to the correct pins on the motherboard.

2: The power LED comes on but the PC does not boot, there is no display on monitor.

Solution: Check if the processor is firmly into the socket. Check CPU jumpers to verify if CPU frequency is correctly set.

3: The PC does not boot, but is beeping.

Solution: Different BIOS manufacturers use various number of beeps to indicate faults with various hardware. In an Award BIOS motherboard you will get following beeps:

1 long 2 short: Graphics card is not securely into place, or faulty.

1 long 3 short: Graphics card is not securely into place, or faulty video memory.

Continuous beeps: No memory, or memory not securely into place, or could be faulty.

Continuous high/low beeps: No CPU, or CPU not securely into place, or could be faulty.

Please refer to your motherboard manual to confirm what the beeps are trying to tell you.

4: The PC boots but the CPU speed is incorrect.

Solution: The CPU frequency jumper setting is incorrect. Refer to your motherboard manual to set it correctly.

5: The HDD is not being detected by the BIOS.

Solution: Check if you connected the IDE cable to the motherboard correctly, is pin 1 on the IDE cable connected to pin 1 on the IDE sockets on both motherboard connector and HDD connector. Check if the HDD jumper is set to master and any other device sharing the same cable is set to slave. 

6: I can not access my CD/DVD-ROM in DOS mode, hence can not install Windows.

Solution: CD/DVD-ROM device driver is not installed. Install the manufacturer supplied device driver. If you do not have a device driver disk, you can use the windows boot disk which will provide access to your CD/DVD-ROM, so that you can install Windows.
