There are a variety of timing utilities available on the various platforms. For detailed information look in the timing utilities section of the software page.

You'll need both X-windows server software (like Exceed) and a secure shell package, such as SecureCRT or Putty. Below are the steps to configure Exceed and SecureCRT:

• Once Exceed is installed:
  • Click Start -> Hummingbird -> Exceed -> xconfig (or rt. clic k Exceed in Task Bar -> Tools -> configuration)
  • Dbl click on Security icon and select "Enabled (no host acce ss)".
  • Click "OK" and close window.
• Once SecureCRT is installed:
  • Start SecureCRT.
  • Click File -> Quick Connect
  • Set Protocol: ssh2
  • Hostname:
  • SSH Server: Standard
  • Click on the "Advanced.." button -> click on the "Port Forwarding" tab and check the "Forward X11 Packets"
  • Click OK

Exceed does not have SSH built into it. You MUST have Exceed running in order to display an "X" window back to your Windows PC. When Exceed is running, click the "Connect" button in Secure CRT and enter user name and password to connect.

You can change your password on any of the CHPC systems using the command yppasswd. This will change your password on all of the HPC systems as well as most other linux systems supported by CHPC. There are certain exceptions, notably the wormhole.inscc.utah.edu machine. You should receive instructions for changing your password on wormhole when you receive the account.

Send an email to issues@chpc.utah.edu and make a request to have your shell changed.

CHPC does not provide new users with a standard set of . ("dot") files. However, there are some you may download if you choose which will setup your environment with most of the paths you'll need. This is particularly important if you are running on the Arches clusters. These files are available here:

Default .tcshrc login script for CHPC systems

Default .bashrc login script for CHPC systems

The instructions and settings are online at: http://wiki.chpc.utah.edu/index.php/Improved_wireless_security

No. Please contact us if you have particular requirement for this by sending email to issues@chpc.utah.edu.
