FAQ – Computational Servers

Computational Server

Which username/password should i use for [insert service name]?

We have evolved to where each user has one username and ONE password. We may refer to your CADE or CoE username and password. This is separate from your CIS/uNID and it’s password, but we may ask you to use those for authentication, such as when creating your account or changing your password.

Your CADE/CoE username is some combination of letters from your names (First, Middle(s), & Last) and generated by an algorithm. Once created, we don’t change them except in rare circumstances.

Your CADE/CoE account is use for:
• logging in to any Linux, MacOS, or Windows computer on our Domain (USERS\ or users.coe.utah.edu), including lab machines, Terminal Servers, VDI hosts, or other Virtual Machines.
• connecting/mounting a Network File Share with CIFS/SMB.
• WebPrint and any PaperCut printing services.
• logging in to your DreamSpark and MSDNAA accounts.
• mounting a Network File Share with NFS.

Note: Your CADE/CoE username and passwords are 100% separate and in addition to your CIS or other campus logins and accounts. Some departments may have labs or computers that require specific logins.


Computational Server

CADE no longer provides Computational Servers.

compute1.eng.utah.edu has been retired as of 10/4/2016 and files that where located under /scratch have been mounted on any lab1 or lab2 machine. The files are located at /research/scratch/{USERNAME}

/research/scratch works on auto mount. You will not see anything until moved into /research/scratch/{USERNAME}

If you need to run long computational jobs or higher-powered computing resources, we suggest getting an account with CHPC.


Which machines can I access remotely?

You can access any of the machines within the CADE Lab (Linux) with ssh, VNC, NoMachine, etc., and the SD Mac Lab (Apple OS X) with ssh. For ssh, from a terminal window, use ‘ssh -Y username@machine.eng.utah.edu’, where username is your CADE login. The naming convention for machine is:

lab1-X (where X is any number from 1-40)
lab2-Y (where Y is any number from 1-35)

SD Mac Lab
lab8-Z (where Z is any number between 1-32)
Please note that remote access to the Apple’s is with ssh only (no VNC, NoMachine or other GUI connections).  Marriott Library does offer full GUI remote access to Mac Terminal Servers – see these instructions.

If you are using a Windows system to access these machines remotely, please use Window PowerShell, putty or see our FAQ’s on CADE Lab Remote Access.

Windows Machines:
You can not access the Engman Lab machines directly but you may access our Windows TerminalServers(animal.eng.utah.edu) for remote access to some Windows software or the VMware VDI pools for a lab-machine setup.

Please see the Windows FAQ’s for more information on how to connect to the Windows system.


How do I log into a CADE machine if I get a warning message saying ‘Host Key Verification Failed’?

Likely, the message you recieved looks like this:

Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is(…).
Please contact your system administrator.
Add correct host key in /home/username/.ssh/known_hosts to get rid of this message.
Offending key in /home/username/.ssh/known_hosts:xx
RSA host key for lab-machine has changed and you have requested strict checking.
Host key verification failed.
You can completely delete the existing ‘known_hosts‘ file in your .ssh directory to avoid this message and log in, or as the message states, remove the offending line. The ‘known_hosts’ file will be repopulated, and a machine entry will be added each time you log in to a different machine.

rm ~/.ssh/known_hosts

You can add the correct host key containing entries of all the CADE lab machines from a file on our website, available here.
