- 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 setuid root.
- Please be aware that iLab machines have a new CPU Limit policy enforced limitation to prevent abuse and runaway processes.
- Dropbox No longer works due to new requirement of glibc 2.19 or higher and ext4 file system 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: ilab.cs.rutgers.edu 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.
- Announcing a new 100GB disk space available for every user and can be accessed at/common/users/your_netid. 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: ilab.cs.rutgers.edu which will randomly pick ilab1.cs, ilab2.cs or ilab3.cs. If you prefer other machines, please look at the usage graphs to find other iLab machines.
- If you have issue with specific iLab machine, report it to firstname.lastname@example.org, check Status of iLab Machines and pick a different machine.
- Trouble logging in?
- Have you Created or activated your account?
- Have you Set your CS Password and use it to login?
- There are many available machines you can access locally and remotely. Unless there are specific features you need, example: class virtual machine or CUDA chips, they are essentially the same. Try find machines with less Users and lower Load for better speed.
- Check Current Status of CS Resources in case we have bigger issues.

Using iLab Machines in Hill 248, Hill 252 and Hill 254
To use CS iLab Machines, we recommend:
- Log in directly to a machine located in the Hill Labs (Hill 120, Hill 248, or Hill 252)
- Use Remote Graphical Display, using X2Go client. See instructions on how to do this.
- Use Remote Graphical Display using Microsoft Remote Desktop client. (Starting Fall 2018)
- An SSH client for a remote command line interface like Putty, Secure Shell aka WinSSH .
- A local X-Server (such as Xming or Cygwin on Windows or XQuarts on MacOSX ) and remotely X-Tunnel graphical applications using an SSH client
- If you have issue with specific machine, please check Status of iLab machines.
Home Pages for Students
