CS users have two main choices when it comes to remote hosts for login sessions. (They run on the same physical hardware and run Ubuntu Linux.)

After the shutdown of chandra, “” is no longer a destination that users can log into. If you have instructions for students that refer to this destination for getting to a login shell or to access files, please notify them to use:

We will be finally pulling the plug on the last two Solaris Sparc systems in CS - chandra and cepheus. They are pretty old (7+ years) and no longer have any supported user environments on them since everyone moved to Linux. We will do the shutdown in the afternoon of Friday, October 7, at about 3pm.


Problems with MacOS Sierra for Mac users
Written by Janaka Jayawardena   
Thursday, 22 September 2016

On September 20th, Apple released the latest version of their computer operating system - MacOS Sierra (10.12). We have seen these problems reported:

1) MacOS Sierra has changed natively supported VPN types. Sierra users are having trouble connecting to our older Windows-based VPN. It is not yet known if our other VPN offering (openVPN) works properly or not.

2) Mathworks has alerted users that Matlab on MacOS is having some non-US localization problems (regions and locales) and is warning users to not install Sierra if they may be exposed to that problem.

We recommend that Mac users avoid installing Sierra until we have had a chance to study the VPN issue. We may not get to that until we have made it through the frenzy of the first few weeks of the term.
