CADE SSH Open Again – Requires OTP

In April of this year, we made the hard decision to restrict remote access to the lab machines to on-campus or VPN only.

Since then, we’ve been looking at options for integrating two-factor authentication in order to make the Linux machines directly accessible off campus once again. The 2fa solution that we’ve settled on is password + TOTP authentication.

When connecting to the CADE Linux machines from on campus or the VPN, you may connect as usual with a password or an SSH key. When connecting from off campus, you’ll need both your CADE password and a one time code.

To register a TOTP app, log into the CADE Linux machines from on-campus or the VPN.

1. Go to Applications > CADE > Configure 2FA or from a terminal run configure-2fa.sh. This will display a QR Code on the screen.

2. Using Duo (or any other TOTP app), scan the QR Code. This will create a new entry for the CADE Linux machines.

3. When SSHing from off campus, you will be prompted to enter your password, followed by a prompt to enter your TOTP code.

CADE Firewall Changes

UPDATE: SSH and NoMachine are open again without the VPN. 2FA is now required.

Due to increasing cybersecurity threats, as of April 25, 2023, CADE has restricted SSH, NoMachine and VMware Horizon access from off-campus to require using the campus VPN in order to connect.

For now this includes:

* SSH and NoMachine/NX to the CADE Lab Linux computers (labs 1 & 2)
* VMware Horizon access to the Window VDI Pools (Engman & ME EN 7530 pools)

Information about using the Campus VPN can be found here:

Over the next few weeks, we will be tightening down additional networks from off campus access.

Retiring mysql.eng.utah.edu

CADE will be retiring the old MySQL server named mysql.eng.utah.edu on March 1st, 2022. As of January 2022, there appear to be no active users of this server, as all new databases since 2017 have been created on the new server (maria.eng.utah.edu).

If you need an old database moved to the new server, please send a request to opers@eng.utah.edu and we’d be happy to move it over.

We’ll be keeping this server around after shutdown for at least two years if any old data needs to be recovered.

Mac Lab Remote Access

Starting April 25, 2023, remote access to the MGK Mac Lab (lab8) will be disallowed.
To access these machines, come to campus.

We previously allowed ssh access only; GUI/Finder access has never been allowed.

Linux Lab Upgrades

Starting Sunday, July 25th, the CADE lab will be unavailable through the 29th due to hardware and software upgrades.

At least half the machines will be online at any time. These machines will be accessible remotely here: https://nx.eng.utah.edu

SVN Server Shutdown

CADE’s long running SVN server (lenny.eng.utah.edu) will be retired on September 1st 2021 due to little usage. Please contact us if you have any questions.

Mail Server Upgrades

On May 27 2021, CADE will be upgrading mail servers. For nearly all users, this should be an invisible upgrade. Users who may be affected are those with older mail clients or operating systems that do not support modern encryption standards. We will be raising the minimum requirement to TLSv1.2, just as we have already done for the large majority of our websites.

The following list of common mail clients should be supported:

  • Outlook 2013+
  • Apple Mail / OSX 10.12 (Sierra) and above
  • Mail / iOS 11+
  • Mail / Android 5+
  • Thunderbird 45.6+

If you experience email issues after the upgrade, please contact us and we’ll be happy to get you upgraded.

CADE email is also available using the web interface at webmail.eng.utah.edu.
