As of March 11, 2020, due to  Covid-19 crisis, University  requires students  to work remotely and to suspend face to face instruction, please consult Working at Home page to assist you with your computing need at home.
Past Announcements
  • As of October 1, 2019, we have enabled access to /dresden/users home directory on iLab machines. This means CBIM users who has access to /dresden/users home directory can access their data from iLab machines without first copying them locally saving everyone both  time and disk space.
  • Please connect with us on Twitter @RutgersLCSR for up-to-date announcements
  • If you are new to CS Resources, see Beginners info
  • For users who are have issues with logging in or access, please go to Core 211 between 10:30a-5pm to resolve your issues. If you use it, please bring your laptop
  • For students learning to program with fork,  see  Preventing Fork Bomb on Linux
  • Attention CS416 students. Please be aware that fuse mount point must be set in /tmp/ or /freespace/local/ or your program will hang. The reason: root has no access to home dir and fuse is run by root.
  • Please be aware that iLab machines have a new CPU Limit policyenforced limitation to prevent abuse and runaway processes.
  • Dropbox  is not supported as of Oct 15 2018. Use Scarletmail Google Drive. You have unlimited space there instead of 2GB from Dropbox.
  • If you have issue connecting to CS machines, make sure to check if your IP is blocked and how to get around the block.
  • Starting Fall 2018, all users should be using a machine named: which will randomly pick ilab1.cs, ilab2.cs or ilab3.cs. See iLab Machine Status to find status of all iLab servers and iLab desktop machines.
  • If you are using python, please follow Using Python on CS Linux machines instruction or many modules wont load properly.
  • If you are doing big data with Hadoop, Please see CS Hadoop Cluster information page.
  • If you need more space, store them in/common/users/your_netid where have 100GB disk space. See  Storage and Technology Options for more info. (July 30, 2018)
  • For those users who use emacs on x2go, please use: emacs-23.1 to avoid compatibility issue.
  • There are reports that some people have Keyring issue. Try to use your NetID password to unlock it. If you continue to have problem,  follow this QuickFix to Gnome Keyring Password instruction.

Finding a Computer to Use

  • We recommend remote users to use machine named: which will randomly pick ilab1.cs, ilab2.cs or ilab3.cs. If you prefer other machines, please  look at the iLab machines status to find the best iLab machines to use.
  • If you have issue with specific iLab machine, report it to, check  Status of iLab Machines and pick a different machine.

Using iLab Machines

To use CS iLab Machines, we recommend:

Home Pages for Students

You can setup iLab home pages. This homepage needs to be stored in world readable public_html folder (~netid/public_html) and is accessible via http://
