CADE Firewall Changes

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.


CADE will be retiring the old MySQL server named 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 (

If you need an old database moved to the new server, please send a request to 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:

SVN Server Shutdown

CADE’s long running SVN server ( 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

Linux HTML5 Desktops Now Available

CADE is proud to launch NoMachine Cloud Server for remote access to the Linux labs. We have 75 desktops available for use on-campus or off with no need to use a VPN. Simply point your web browser to and log in using your CADE credentials.

As this is a new service, please let us know if you run into any issues.

Looking for Compute Servers?

As CADE no longer offers general use compute servers, we thought some may be interested in other on-campus options. A simple one to set up is through the Center for High Performance Computing ( In addition, they’ve recently announced expanded service through a test/debug queue <>

“We have two new AMD processor (Epyc 7601)  based nodes now available as compute nodes on notchpeak.  Each node has 64 physical cores and 512GB of memory.

Instead of adding these nodes to the  general notchpeak partition, we are using them to explore having a “test or debug” queue, with a shorter maximum wall time.  We are doing this as we have had several requests for a test queue, and the arrival of these nodes has given us an opportunity to see if there will be sufficient usage of this queue.

In order to maximize throughput of short jobs, and provide access to all users, they have been placed in a separate partition, with node sharing enabled. In addition, the nodes are being run such that they will allow a load of twice the number of physical cores, again to maximize job throughput. 

Use of these nodes is limited:

·       Maximum wall time is 4 hours

·       Maximum jobs  in the queue per user is 10

·       Maximum running jobs per user is 2

·       Maximum cores per user is 32

·       Maximum memory per user is 128GB

To use set both the partition and the account to notchpeak-shared

As node sharing is being used – users MUST specify the  number of cores and the amount of memory – see for additional details.

All users have been given access, and the usage of these two nodes will not use any general allocations.

Please report any questions or issues to

PCE Domains available for UMail accounts

CADE may shut down our e-mail servers for POP and IMAP at any time but want to give you all time to move your mail to another account and set up the appropriate aliases with uMail.

In preparation for phasing out the PCE e-mail servers, we have worked with UIT and the uMail team to make College domains available for all PCE faculty, staff and student e-mail addresses.
We can modify your uMail alias (typcically some form of your first, middle and last names and/or initials; Fac/Staff have more leeway than do students) and set your account with any of the following domains:


If you’re interested, send an e-mail to and give us the following information: Full name, uNID, desired alias, which CoE Domain extension you would like and if you’d like the new one set as the Primary alias/Reply-To, or leave it as currently set.

As part of this process, you may set or change your account via the uNID Tools page:
