Quick Info
COELINUX
The COELINUX servers provide a robust, central environment in support of academic classwork that requires a Linux environment in the College of Engineering. There are 6 servers, each with 128 cores and 768GB of RAM. The servers are currently available to students and faculty affiliated with CSE, ECE, and MAE. Pending real-time capacity/utilization analysis, access will be extended to all Engineering units. The servers are not intended to support research computation.
Note: COELINUX is a college-wide resource. As such, it is not connected to unit-specific resources such as printers (though Uniprint's Follow Me printers are available) or local research drives.
Accessing COELINUX
Accessing COELINUX requires SSH or FastX 3 (support for 4 is tentatively scheduled for January 2024), and if off-campus, the Ivanti VPN. SSH is sufficient as a command line interface (CLI), and FastX is required for graphical user interface (GUI).
-
If off-campus or on wireless, you will need to connect to the Ivanti VPN first. VPN Instructions.
-
Once connected to the VPN, you will be able to connect via SSH or FastX. The hostname to connect to will be coelinux.coeit.osu.edu. FastX instructions
Notes:
-
COELINUX is a shared resource. Idle sessions are limited to improve availability. At 2AM each day, idle sessions (defined as not having an active SSH connection) are terminated.
-
Each user has access to up to 8 CPUs and 24GB of RAM. ETS may change these settings if capacity/utilization analysis reveals unfulfilled demand or underutilized capacity.
-
All users should use the round-robin DNS name coelinux.coeit.osu.edu to promote load-balance across the servers. In the event you need to disconnect an active session and return to it later, follow these steps:
-
Use FastX for persistent connections. SSH connections will terminate when the active connection is lost.
-
Prior to disconnecting, note the hostname of the machine your session is on. This information is available by running the ‘hostname’ command.
-
Disconnect the FastX session without logging out.
-
When reconnecting to your previous session, use the hostname of the server hosting the session for your FastX connection.
-
When done with the session, please logout completely and return to using the coelinux.coeit.osu.edu DNS name to keep load balanced across all servers.
-
-
ETS reserves the right to terminate all processes and sessions that are negatively impacting the environment for others at any time without warning.
Accessing Software on COELINUX
In addition to the many software packages provided by the distribution and available by default, third-party and custom software on the COELINUX environment is made available using the LMod tool. This tool replaces older methods of accessing this software including the subscribe command, setup scripts, and login scripts. LMod provides a quick and easy mechanism to load and unload modules from your environment.
To view the list of available software, run the ‘module avail’ command:
To load a module, run the command ‘module load <module name>/<module version>’. The software is immediately available, unlike the subscribe tool which required you to log out and back in to access the software.
It is recommended to load modules only when you need them, but if you use a module consistently, you can add the ‘module load’ commands to the end of your ~/.bashrc file. Note that ETS does not support modified .dotfiles and all debugging processes will start with reverting the file to its default state and issuing ‘module load’ commands individually.
Additional information on LMod can be found at readthedocs.io.
Ivanti Secure VPN (Formerly “Pulse”)
The College of Engineering offers a secure connection method using the Ivanti Secure VPN client.
All downloads come from a SharePoint service that requires OSU authentication. You must have an active OSU ID and BuckeyeSecure.

Installing the Pulse VPN Client
Download the Pulse Secure Linux Client installer from the Engineering Wiki site:
Ivanti Secure VPN (Formerly "Pulse")
If you are prompted to login, simply use your OSU ID and password, after that you may receive a BuckeyePass (DUO) notification for 2-factor authentication – which may not show any prompts on screen.
To install the new client after downloading the installer, run the following commands:
- Ubuntu: "dpkg -i ./ps-pulse-linux-64-bit-installer.deb" in the downloaded folder location.
- Fedora/RHEL/CentOS: "yum install ./ps-pulse-linux-64bit.rpm" in the downloaded folder location.
- RHEL7: "yum install ./ps-pulse-linux-rhel7.rpm" in the downloaded folder location.
To configure and Connect using the Pulse Secure Client
NOTE: Ivanti is changing the UX for their tool. It is functionally and largely organizationally the same. Changes are primarily aesthetic. Depending on your download and settings, the following images may differ from your display, but the content should be relevant.
Open ‘Pulse Secure’ by either searching for it in the Start/Activity/etc. Menu, or clicking on the 'S' logon in the system tray:
In the empty list of connections, click on the “+” button to create a new connection.
Provide a preferred name for the connection, and enter the College VPN server URL: vpn.coeit.osu.edu
Then click on the “Connect” button to save changes and start connecting to the VPN.
Read and accept the sign-in agreement by clicking “Proceed”
Select the ‘CoE-Net’ realm and click “Connect”
Enter your OSU login credentials (i.e. your name.number and password) and click “Connect”
The BuckeyePass authentication prompt is next. This ‘Secondary Password’ is to indicate what method you have selected for the DUO Security 2-factor authentication. Depending on which method you have chosen, you should type in ONE of these options (all lowercase letters):
- push = to use the DUO app to get a push notification for approving 2FA;
- sms = to get a new set of SMS passcodes. Your login attempt will fail — simply log in again with one of your new passcodes. This is also handy if you are traveling and aren't sure about reliable Internet or Cellular connectivity.
- Or you can enter the six-digit passcode from the DUO mobile application (click on the little arrow to the right of “Ohio State University” list entry in your DUO app to reveal the passcode),
Click on the “Connect” button.
Beginning on October 14, 2021, customers will see a second prompt depending on the type of device being used to make the connection:
Customers should choose the Default connection when prompted and click on the “Connect” button. The “- SSL” version can provide higher compatibility at a slight performance penalty on home or other business networks outside of OSU whose configuration may be unique.
The VPN status should now show ‘Connected’, and the little icon in your system tray should have a green arrow beside the Pulse Secure ‘S’ icon.
Note:
The Pulse Secure for Linux Client will not prompt for updates. Please check the "IT News You Can Use" or the Wiki page for updates. Upgrades help ensure communication between your client and our servers are stable, and may resolve errors. Please note that it will likely disconnect your VPN session during installation, so you may need to re-connect manually after the upgrade's installation is done.
If the connection is denied or encounters problems connecting for any reason, Pulse Secure should provide a verbose explanation of any missing requirements or issues during the login process. Please take note or screen capture the error message, and send it to ETShelp@osu.edu for further assistance.
Other Operating Systems
Ivanti Secure Access Clients do exist for other operating systems such as iOS and Android. If desired, they can be downloaded from their respective application stores and installed per the device specific mechanisms. After installation, the configuration is much like that of any other Ivanti client. Refer to the Windows or macOS installation guides above for the connection/realm names and Server URL.
Ivanti Secure Access Client: CEMAS Connection Guide
The College of Engineering offers a secure connection method using the Ivanti Secure VPN client.
All downloads come from a SharePoint service that requires OSU authentication. You must have an active OSU ID and BuckeyeSecure.
Install the Ivanti Secure Access Client
Visit the main ETS Ivanti Pulse Secure Client page and download the appropriate client for your system. Install it per the instructions found there and configure it for the COE-net connection. Once those instructions are fully completed, return to this document.
(Note that in some location, a “connection” such as we are configuring for COE-net and CEMAS may also be called a “realm”.)
Add a CEMAS Connection
The rest of this document is only necessary if you are a member of CEMAS and are connecting to the CEMAS network remotely.
The following screen shots are captured from a Windows 11 device using the new Ivanti Client user interface. Your specific interface may differ cosmetically, but the content remains the same.
As when you added the COE-Net connection in the main installation above, you will now add a CEMAS connection.
First hit the large “Plus” sign in the circle to add a new connection.
You will now enter the three required items to add a connection. The “Type” can remain as the default as shown. The Name is “CEMAS” and the Server URL is “vpn.coeit.osu.edu/CEMAS”. After entering that data hit “Add” to save it for later use.
Once done, you will now have two Connections. To launch the CEMAS connection, just select the CEMAS connection from the list and either hit the gray antenna icon or select “connect” from the vertical 3-dot menu.
