Logging in from UNIX
Access to Cortex is provided through the use of SSH. To connect to Cortex from a UNIX machine, type the following at your shell prompt: ssh username@cortex.cs.unr.edu where username is your username.
When prompted to enter your password, enter the temporary password you received via email. Once logged in, you will receive the yourname@cortex ~> prompt. Please follow the instructions in the Changing your password section below to change your password to something secure.
If you encounter difficulty accessing Cortex via SSH, ensure that you are connecting using SSH version 2. If your machine is not set to use SSH version 2 by default, connect using ssh -2 username@cortex.cs.unr.edu. Only SSH v2 connections are allowed into Cortex per University of Nevada policy.
Logging in from Windows
Logging in to Cortex from any version of Windows requires an SSH client. PuTTY, a free SSH client for Windows is available from here.
After downloading the PuTTY executable and running it, enter your assigned username in the username box. Enter cortex.cs.unr.edu in the hostname box. After all information is filled in, click on connect, and you will be presented with a box in which to enter your password. After entering your password, you will be logged in and receive a shell prompt. From here, follow the instructions on changing your password to change your initial temporary password to something secure.
Changing your Password
The UNIX command to change your password is passwd. To change your password, type passwd at the command prompt. Cortex will prompt you to enter your old password, and a new password twice. If you encounter any errors changing your password, or you cannot remember your password, please contact me.
