Linux Community Servers (LINCOMM) FAQ

A description of the Linux Community Servers (LINCOMM) for use by AAE faculty & students

What is LINCOMM?

LINCOMM is an abbreviation of Linux Community Servers.  These servers are a collection of Linux-based (CentOS 7) machines that are designed specifically for running code.  The user interface is a text-based command line system, specifically Bash shell.

What is the purpose of LINCOMM?

LINCOMM's purpose is to provide access to statistical programs such a R, Stata, Python, and MatLab for code/jobs that require more memory or computing time.

What is different from WINCOMM?

WINCOMM (retiring on Nov 2, 2020), is intended as a full-blown remote-enabled desktop.  It contains a graphical user interface, and can be used for general word processing, web browsing, and light coding of statistical programs (R, MatLab, Stata).   However, the GUI adds additional overhead to the machine, using resources to present to connected users.  It also requires more bandwidth, which can be an issue when connected in a location where the Internet connection is slow or spotty.  LINCOMM is a text-based command line user interface that processes commands and code more efficiently.  Also, since the user interface is all text based, it requires a MUCH lower bandwidth connection to use it.

Also, there is not a login timeout on LINCOMM.   Unlike WINCOMM with its 48-hour timeout, logins are not disconnected (unless the server needs to be rebooted for monthly maintenance, or power outage events).

Who has access?

All AAE faculty, staff and graduate students have access to LINCOMM.   Undergrad students can be granted access with specific permission from AAE professors.

How do I connect to LINCOMM?

Connecting to LINCOMM (Mac) | Connecting to LINCOMM with PuTTY (Windows) | Connecting to LINCOMM with SecureCRT (Windows)

How many LINCOMM servers are there?

Currently there are 4 LINCOMM servers (,,,  However, it is in the long-term plans of AAE to add more servers over time, based on usage and need.

What's the difference between the LINCOMM servers?

Currently there is no difference between the LINCOMM servers.  They are running identical software on very similar hardware.   Some servers have more RAM than others.  If you run into problems with RAM usages, please contact ITSC staff.

Which LINCOMM server should I connect to?

If you are reconnecting to a session already in progress (for instance, you have a job running), you should connect to the server where you had previously connected.  If connecting for the first time, consult the Community Server Availability Dashboard and connect to the system with the least amount of resources in use.

How do I use LINCOMM?

You can read a very BRIEF introduction at Using LINCOMM .   However, it highly recommended to search out a general Linux/Unix tutorial online.
