Scope

This document describes the School of Informatics, Computing, and Engineering Linux systems that are available for use via console/gui logins and remote ssh logins. This includes only the Unified Linux Systems owned and managed by the school for general use by all SICE faculty, staff, and students. There are many other standalone and grant-purchased systems that are not part of the common pool of available Linux systems and, therefore, are not included here. If you have any questions about the availability and use of any of these systems, please contact us.

IU/IUTS Research Systems

Please keep in mind that there are many non-SICE research systems available to all IU researchers.  This includes various large computing and storage systems, including Big Red II, Karst, Mason, and the Scholarly Data Archive (SDA) that we encourage you to take advantage of.  See the Research System Knowledge Base Page and the UITS Research Technologies Homepage for further information about these systems.

Linux Account Information

There is good general information about getting started in the SICE unified linux environment in this KB page:

[Getting Started in the Unified Linux Environment]


You can find out if you have an account on the unified Linux systems and get detailed information about your account here:

Linux System Information

You can also get detailed information about any linux system by running the config command from any shell prompt.

Account Domains

Accounts on these Linux systems are organized by the following password domains:

 

Caveats and Tips

These systems are shared resources that are used by many people. While there are few limitations on their use, please use them in a way that minimizes your overall impact on other users. For example, limit the number of simultaneous CPU or memory intensive process, kill runaway processes, and use nice for long-running processes that consume a lot of CPU cycles. For more information about viewing and killing processes as well as using nice to adjust a processes priority, please see the following KB page:

[SOICKB:How do I view, kill, or nice processes I have running on a Linux system?]

When using Linux systems remotely, you may find that the screen utility is a very convenient way to start a process, detach from it (leaving it running), and then reattach later on. Basic information about using screen is available in the following KB page:

[How do I use screen on the Linux systems?]

Also note that there is a wide array of software available on the unified Linux systems. Please see the following KB page for information about the installed software and how to request the installation of new software:

[SOICKB:How do I get new or updated software installed on the unified Linux systems?]

Various storage space is accessible from these unified Linux systems. Please see the following KB page for information about the available storage space:

[SOICKB:What data storage space is available on the unified Linux systems?]

Available Systems - Remote Use

There are a number of central servers available for remote use. Login access to these systems is via ssh.  See the KB page SSH Remote Logins and File Transfer to Linux Servers for more information about the available SSH client tools.

Available Systems - Local Console/GUI Use

In addition to the Linux systems in the various individual and shared offices, there are systems available for console use
