  • Move to Duo
    You have probably heard that campus is moving to using  the multi-factor authentication system Duo. This makes it much harder for hackers to access your UC Davis accounts. Even if someone has stolen your passphrase, they will still need a “second factor”.

    The System Support Group (SSG) is here to help you move to Duo.  Here is a step by step walkthrough that should help you to move to Duo. 


    Faculty and Staff are supposed to move to Duo by the middle of February. The SSG encourages everyone to move to Duo as soon as possible, because of the protections Duo provides.

    If the walkthrough doesn't work for you, please contact us at support@cs.ucdavis.edu.

  • Be on the lookout for Phishing Attacks
    There have been a few social engineering attacks via email that have slipped by our spam firewall and Google's security measures. Be on your guard!

    The most common of these phishing attacks com from some trusted entity, such as Campus IT, or from a service used in academia, like Blackboard. The message might say you have a message, or it might say your password is going to expire, anything to get you to click and login with your campus credentials which are then stolen, along with any data associated with that password.

    Don't click on links you are unsure of. Do not re-use passwords for multiple services. Use a two-factor authenticator when available.

    The Systems Support Group (SSG) highly recommends turning on Google's 2-Step Verification to protect your Google account (Davismail). There are a few ways to authenticate using this service, including a very convenient code sent to your phone via text.

    This two-factor authentication is an effective method for countering phishing attacks, as it adds an extra verification layer when logging into sensitive applications. It's a good idea to apply two-factor authentication on a service when you can.

CS Website web.cs.ucdavis.edu now SSL encrypted! (https://)

posted Apr 26, 2019, 10:45 AM by Ken Gribble

This week the CS website that supports the traditional ~ (public_html) sites has been updated to use SSL encryption. Now you will find pages there are enforcing https instead of http. If you notice that the lock symbol is missing from your ~ site, it may mean you have something on your page that is unencrypted.


As always, please contact support@cs.ucdavis.edu if you have any troubles or concerns.

The CSIF has new home directories

posted Sep 17, 2018, 10:50 AM by Ken Gribble   [ updated Sep 27, 2018, 11:36 AM by Jim Moersfelder ]

The Computer Science Instructional Facility has a new set of home directories in the CSIF and old home directories have been archived. 
The old home directories are still mounted on sp2.cs.ucdavis.edu as read-only.  Please, only use sp2 to retrieve or backup your files from the old home directory.

If you want to move your files from the old home directory to your new home directory we suggest logging into a system in the CSIF, for example pc14.cs.ucdavis.edu and executing one of these 3 rsync commands below:


** WARNING ** 
If you have created a file on the new home directory that is named the same and in the same location as the file on the old home directory and you rsync that directory to the same place, it will over write the file on the new home directory.    
** WARNING ** 


In the below commands, change "USERNAME" to your username in the CSIF.

If you want to copy a directory from your old home directory called "OLD_DIRECTORY" to your new directory use this command:
rsync -avhHSe ssh USERNAME@sp2:/home/USERNAME/OLD_DIRECTORY /home/USERNAME/

If you want to copy your entire old home directory to your new home directory use the following command:
rsync -avhHSe ssh USERNAME@sp2:/home/USERNAME/ /home/USERNAME/

If you want to copy your entire old home directory to a directory called "OldHome" in your new home directory use this command:
rsync -avhHSe ssh USERNAME@sp2:/home/USERNAME/ /home/USERNAME/OldHome/

Remember the "/" is important, often without it, rsync puts files in different locations.  

If you have any questions or need help please email support@cs.ucdavis.edu.
