Keller Hall Networking

The network in Keller Hall will be upgraded next week as part of OIT's Next-Generation-Network (NGN) project. Keller Hall was originally scheduled to be upgraded in February of 2020, but OIT has now pushed the timeline up to August and we are doing our best to accommodate their new schedule. 
 
KELLER HALL DATES: 8/15/2019 - 8/19/2019
 
OIT installs new network equipment alongside CSE-IT's private network equipment so the private LAN and the OIT network work side by side on or around.

Network for hosts in the machine room

CSE-IT has identified an issue with a switch in our data center leading to some hosts losing network. Currently, there are two hosts affected by this, minerva and titan-umh. We will keep you updated. If you have additional issues please contact csehelp@umn.edu

UPDATE 7/30/19 10:00AM: CSE-IT has fixed the issue by removing a bad PDU as the power source. Please contact csehelp@umn.edu if you still have issues.

CS Faculty Portal

The CS Faculty Portal will be inaccessible for up to two hours beginning at 1PM today for a change to the authentication system. The CS Faculty Portal will move from using old CS Unix accounts to using central University authentication (internet ID). The system will be online again no later than 3 PM. Please email csehelp@umn.edu for questions

UPDATE: This change is complete. Users should now login to the CS faculty portal using their internet ID and password.

Tate Hall Networking

At 9AM today, CSE-IT began receiving reports of issues regarding Linux computers in Tate Hall having network connectivity problems. Our analysis indicates a DHCP server issue, so computers are not receiving IP addresses and are not able to connect to their wired network. The problem is ongoing and we have no current estimated time for a resolution. We will update this notice at 12PM today.

UPDATE 12:00PM: CSE-IT is working together with NTS to resolve this issue. We will keep you updated.

CS Mail

mail.cs was affected by a compromised email account. CS mail is currently down and mail delivery will be impacted for several days. We will post updates here when we have them. If you have any questions or concerns please email csehelp@umn.edu. 

Update 1:50 PM: CS mail has been brought back online and is processing a large backlog of emails. Users will likely still have significant mail delivery delays. 

Vole

We are currently experiencing issues with one of our Vole nodes. We are aware of the issue and are working on a fix. You will likely see the error (Xrdp failed to start: Exit Code 1)

Update 2:00PM: We have found the root cause of this error to be a full /tmp directory on one of the nodes. This has been cleared up and users should not have any other issues. Let us know if you are still experiencing difficulties by contacting csehelp@umn.edu.
