General ARCC Troubleshooting

For general issues please see our Known Issues page to see if the problem could be caused by something that we already are aware of and recommended solutions or work arounds.

Do I have to have a smartphone to use two-factor for ARCC services?

• No, there are other options:

  • You have to purchase a Yubikey from UWIT.

  • You can enroll in any phone number or device on Duo.

    • When logging into Teton using the landline method, type “<your password>, phone“ and your enrolled number will get a call.

My UWyo user account is locked/disabled, can ARCC restore it so I can use the petaLibrary and/or Teton?

• No, ARCC does not manage UWyo accounts. Contact the UWIT Accounts Office for help.

  • For further information on UWyo accounts see UW Accounts FAQ

Teton

I am having trouble logging into Teton.

• Can you log into other Uwyo resources?

  • If no, contact IT Helpdesk.

• Is your 2nd-factor authentication working? Test on https://wyosecure.uwyo.edu

  • Check out https://uwyo.teamdynamix.com/TDClient/KB/ArticleDet?ID=63314 to see if your device is properly configured.

  • If you are having problems with your second factor you will need to contact IT Help Desk.

• There is a known issue on Teton that may affect your login. Wait until the top of an hour (e.g. 1 pm) and try again. We have an automatic process to fix this issue that runs every hour on the hour.

• If you are still having problems email contact us.

How do I access Teton when I am not on the UWyo network?

• Teton's login nodes are on the Science DMZ network outside of UWyo firewalls. Meaning you can log into Teton from anywhere as long as you have an internet connection and a terminal or ssh client.

How do I run my code on Teton?

• You must submit your code to the job scheduler. Running code on login nodes is not permitted.

  • For more information about the job scheduler please see our page on Slurm.

How do I find out what modules/packages are available on Teton?

• While logged into Teton, executing the command "module spider" will list all modules installed on Teton.

$ module spider
To learn more about a package execute:

$ module spider Foo

where "Foo" is the name of a module.

To find detailed information about a particular package you
must specify the version if there is more than one version:

$ module spider Foo/11.1

May I have sudo access on Teton?

• Users will never have sudo access. Email arcc-help@uwyo.edu to request whatever would you need sudo access for.

My Teton home directory is full, can I get more space?

• Rarely do we increase home directory space, please clean up any unnecessary files first. If the problem persists, email arcc-help@uwyo.edu to describe your issue.
