Remote Access

Access to User Account and Files

Users without a reservation can always access their account's home directories, files, and BASH scripts through SSH by connecting to: 

ssh USERNAME@gw.cosmos-lab.org

Access to Consoles

The domain consoles can be accessed the same way as the gateway (above), with the following differences: 

ssh USERNAME@console.DOMAIN.cosmos-lab.org

Access Resources via Console

Resources can only be accessed by running commands from a console or by establishing a connection through the console. For people unfamiliar with ​ProxyJump, the following is recommended:

  • SSH into your domain console.
  • Use OMF commands to
    • Turn resources on/off
    • Load and save images
    • Run OEDL Scripts with OMF exec
  • Open an interactive session wtih SSH from a console to compute resource.
  • Use SSH w/ X11 Forwarding to view a graphical window from a resource on your local machine.
    • REMINDER: you can only SSH w/ X11 by adding argument -X or -Y to every SSH command.
  • Example: 
    ssh -X USERNAME@console.DOMAIN.cosmos-lab.org

    ssh -X root@COMPUTE_RESOURCE

Access to Resources Directly

This is a convenient only if bridging through the console adds unacceptable overhead or difficulty to your use case. You can only ​ProxyJump if you have a current and approved reservation. Your resource also must be turned on beforehand. 

ssh -J USERNAME@console.DOMAIN.cosmos-lab.org root@RESOURCE

Access Tips w/ SSH

The prominent method of connecting to the testbed is via SSH. The SSH protocol is quite powerful, allowing interactive shell sessions, file transfers, port forwarding, and even graphical displays if configured properly with other utilities. Please consult for further help:

Access via Third Party Software

Access via VPN

In cases where SSH is insufficient or inconvenient, an IPSEC VPN is available.

Site to Site Connection

If you have a need to bridge a remote network with ORBIT/COSMOS testbed, this must be manually arranged with the testbed maintainers. This is usually done to provide connectivity between a Vendor's test device and some testbed experiment or in case of special demo requirements.

  • For our recommends parameters, see site-to-site that will need to be customized per-connection.
  • Please ​contact us for more information.
