CCIS Systems supports Fedora 22 in the main lab in 102 West Village H and on faculty and grad desktops.

Remote Access

Holders of valid CCIS UNIX accounts may connect to the following public machines using ssh:

  1. login.ccs.neu.edu
  2. Any of the CCIS Lab Linux machines which are physically located in West Village H 102.

Note that login.ccs.neu.edu‘s ssh host keys changed on September 1, 2015, when the server hardware was migrated from Ubuntu to Fedora. If you’ve been around the college since before September 2015, it’s possible that your ssh client may have the ssh host key from the old login cached, which will cause warnings when you connect to the current login (running Fedora). See the above linked blog post for instructions on dealing with this problem should you encounter it.

Local Access

CCIS Majors and students enrolled in CCIS courses may use our public lab in West Village H 102. Faculty, graduate students, and staff may have dedicated Linux machines on their desks.

Hardware and nomenclature

Our Linux machines are named after classic video arcade games.

The approximately 40 Linux machines in the main CCIS lab in 102 WVH are all Dell Optiplex desktops, which are replaced with the latest available hardware every few years. As of Fall 2015, our Linux machines are Optiplex 9020 Micros with Core i7 processors, SSDs, and 16GB of RAM. Note that 102 WVH has Dells running both Linux and Windows; The Linux machines will display “Fedora” in the lower left hand corner of their screens while the Windows machines will display “Windows” at the bottom center of their screens. The Linux and Windows desktops also have different background images.

The model of the other Linux desktops at CCIS varies based on when the computer was purchased and the specifications with which it was ordered, but they are generally within a generation or two (either older or newer) of what is to be found in our labs.

login and back-end services

The login.ccs.neu.edu shell server, as well as various other public, CCIS-facing, or back-end services (including our mail services, and Wiki services, and assorted behind-the-scenes programs needed to keep everything else functioning) are also built on CCIS Linux, either running directly on Dell server-class hardware, or as virtual machines atop Xen, VMware Infrastructure, or Microsoft Hyper-V, in turn running on similar server-class hardware.

Where do I find list of CCS machine hostnames?

Sorry, that’s not something we publish publicly.
