Starting Fall term, access to the FAB/EB building is by PSU ID Badge only. We have added an online portal for MCECS students to request 24x7 access to FAB/EB and the following computer labs: FAB MCECS General Lab “Intel Lab” - FAB 55-17 EB MCECS General Lab “CadLab” - EB 325 CS “Particle” Linux Lab [...]
If you are a user of the following Linux systems, read on: linux.cecs.pdx.edu ruby.cecs.pdx.edu rita.cecs.pdx.edu At about noon on Monday, August 2nd, 2021, we will be changing the SSH keys on the Linux computers listed above. Anyone who has been logging into these systems on a regular basis will be greeted with a verbose “host [...]
In an attempt to modernize our SSH infrastructure, we’ve made some changes to SSH keys on our Linux computers. We’ve disabled DSA host keys, and enabled new ECDSA and ED25519 host keys. This process took a few days, and during that time a few hosts had their keys changed. If you are experiencing problems trying [...]
As seen in recent headlines, institutionally targeted ransomware attacks are on the rise. The initial entry for these attackers seem to use many of the same techniques that we have seen in the past so it is becoming very important, as frequent computer users, to keep our guard up.

Greetings from the Computer Action Team! Fall 2020 is going to be a remotely-accessed experience for most MCECS users. Whether you’re a student, faculty, or staff, you can learn more about your MCECS account by following this link: https://cat.pdx.edu/users/getting-help/ We have built a resource that catalogs many of the most commonly asked questions we encountered [...]
Logins to most CAT supported Linux systems are moving to a different underlying authentication system (known as “kerberos”). Here are the potential side effects of that change. 1) Login using password This is the most common method used for logging in. With a few exceptions, users will not notice any change. If you are unable [...]
MySQL and Postgres users, As a security measure, we are putting the externally available web interfaces for our user based MySQL and Postgres database servers on db.cecs.pdx.edu behind MCECS authentication. This means that users who want to get to those interfaces will have to first authenticate with their MCECS credentials (login/password). For MySQL details, see: [...]
[For database/web developers in MCECS] While direct client access to CAT managed Postgres and MySQL database services are firewalled, the web interfaces for manipulating those databases, phpPgAdmin and phpMyAdmin, have been directly accessible without the need for a VPN. On Wednesday, June 17th, we will be locking down access to these web interfaces as well. [...]
