Accounts

All NPU students are entitled to the following computer accounts, which provide access to a variety of services:

NOTE:
  1. Every new student will receive an email with all your account information after reporting to NPU.
  2. Your Windows, Unix/Linux, NPUOSC and other accounts are different accounts. If you changed one account's password, it will NOT affect others.

Windows Accounts

When your Windows account is created, a predefined disk quota is set to ensure every student can share the server while protecting the system by preventing a user from taking up all available disk spaces.

1. Login
  • Enter your username
  • Enter your password
  • Domain: select NPU_NETLAB

2. Change Password

A user can change his or her password after a successful login.
Press on "Ctrl"+"Alt"+"Delect" key to invoke the "Change Password" dialog box.

Unix/Linux Accounts

Your Unix/Linux Account is a separate account from your Windows Account. Usually, the username of your Unix/Linux Account is as same as your Windows Account's.

1. Login through Xmanager

Open Xmanager, choose Xbrowser to display the servers, and double click the server you want to access

Type your user name and password of Unix/Linux

2.Through SSH (using Putty)

This option is used outside of campus because it's more secure to connect server through SSH.

· Why SSH?

SSH ("secure shell") provides a way to transfer information securely from one computer to another. For example, if you use SSH to login to NPU servers from outside of campus, your password would be encrypted before being sent over the network. Therefore it would be of no use to someone intercepting ("sniffing") network traffic. Your SSH client encrypts information, which is then sent over the network to another computer where an SSH server decrypts the information it receives.

· Download SSH Client Tool

SSH client tools are available at Downloads

· Run SSH

Open Putty, and type the server IP address you want to access

Type your user name and password of Unix/Linux

· More about SSH?

Technical information on SSH is available at http://www.ssh.com/faq/
Technical information on OpenSSH, the freeware version for UNIX can be found at http://www.openssh.org/

2. Change Password

After login to the UNIX server, you can change your password by using the "passwd" command.

  1. Enter command "passwd"
  2. Enter current password
  3. Enter new password
  4. Confirm new password

3. Fail to login?

  • Make sure to input the correct username and password, it's case sensitive in UNIX.
  • Submit an Online Support Form.
  • Fill in and submit a Service Request Form at Room 222.

4. Disk Quota

If you are over your disk quota, you will not be able to write and save data into your home directory. You will experience an error message like "xxxx, Disc quota exceeded".

If you forgot your NPUOSC Account's password, you can reset your password by clicking "Forgot your password" link at the login page of the NPUOSC web. The new password will be sent to your email address which you provided to us earlier.
