The ssh-linux servers ssh-linux4, ssh-linux5, ssh-linux7, and ssh-linux8, which are running Debian 6, are scheduled to be replaced.

Notable changes

  • The new server pool is called ssh-ubuntu.ece.ubc.ca.
  • Operating system is Ubuntu 14.04 rather than Debian 6.
  • Expanded list of installed software packages. (If any Ubuntu package that you want to use is not installed, please file a request.)
  • MATLAB version is R2014a; versions R2008b and R2013b have been dropped.
  • Hosted on virtual servers in the University Data Centre for better performance and reliability.

Upgrade plan

  1. As of now, you can start using the new servers by using ssh-ubuntu.ece.ubc.ca as the server hostname (instead of ssh-linux.ece.ubc.ca or ssh.ece.ubc.ca).
  2. As part of the ECE Storage Migration, all ssh-linux servers (both Debian and Ubuntu) will be rebooted the night of August 22. After the reboot, ssh-linux will point to the new Ubuntu servers. You will still be able to connect to ssh-linux4, ssh-linux5, ssh-linux7, or ssh-linux8 explicitly.
  3. In a few months, we will shut down the old servers completely.
