System Access

Operating Systems

There are two classes of operating systems in general use by the department: Windows and Unix. All Instructional Labs currently use Windows. Almost all servers are running Unix.

Computer Access Groups

Access to Computers is restricted by Computer Access Groups. Visit the Card/Group Management link to request access to groups, such as research lab groups.

Logging in to Windows

When you sit down at the machine, there should be a login dialog where you can enter your login name and password.

To log out, press Ctrl-Alt-Delete and select "Sign Out"

Logging in to UNIX

Just type in your login name and password where prompted. For security reasons, your password won't be echoed when you type it.

To log out, type "exit" or "logout". When the login prompt appears again, you know you have been logged out.

Accessing Files From Home

Mapping Your Home (Z) Drive

You can map your Z drive from home. Please use the Tutorial Provided

Transfering Files using SSH SFTP

To transfer your files on a Windows machine, please use the freely available program SSH SFTP. Click here to download SSH SFTP. Use the hostname to connect.

Unix Users:

To use scp on a Unix system:

A. To transfer one file:

1. Go into the directory containing the file.
2. Type "scp [the filename] [your login][the directory you wish to send it to]"

scp temp.doc

B. To transfer an entire folder:

1. Go into the directory containing the folder u wish to transfer.
2. Type "scp -r [name of the folder]/ [your login][the directory you wish to send it to]"

scp -r projects/

Loggin in From Home using SSH

For Windows Users:

To use SSH from a Windows machine, please use the freely available program PUTTY. Simply DOWNLOAD PUTTY HERE and save it to your desktop. Then, once downloaded, double click on the file putty.exe that was downloaded to your desktop, type in the hostname (, change the protocol to "SSH," and be sure that the port is 22. In the left menu, click on "SSH," then under "Protocol options," go under "Preferred SSH protocol version" and click on 2. Go back to the "Session" category, in the left menu, type a name in the box "STORED SESSIONS" click "SAVE" (this will only need to be done the first time you use putty), and click "OPEN." Subsequent use of putty to connect to this same server can be done by double-clicking the stored session that now appears in the "Stored Sessions" box.

If you have problems connecting to, connect to your UCR student account, and then connect to gauss using the following command:


For Unix Users:

To use ssh on a Unix system, download the SSH source code and compile/install it yourself. There are two major versions, SSH and SSH2. Gauss currently has SSH2 and SSH1 installed, but SSH1 will soon be removed so download SSH2. Once you have it downloaded:

1. Unpack it with 'tar -xvzf ssh-1.2.27.tar.gz'
2. cd ssh-1.2.27
3. ./configure
4. make
5. make install
