Getting Started on Swing

Accessing Swing

Due to updated security requirements, direct SSH access to Swing is no longer permitted. All inbound access must now go through the CELS login nodes using a jump host configuration.

You cannot SSH directly into the CELS login nodes. Instead, connect using the command below (replacing and accordingly):

ssh -o ProxyCommand="ssh -i ~/.ssh/<ssh_private_key> -W %h:%p <username>@logins.lcrc.anl.gov" -i ~/.ssh/<ssh_private_key> <username>@swing.lcrc.anl.gov

Alternatively, you can simplify future connections by adding the following block to your ~/.ssh/config:

Host logins.lcrc.anl.gov
  HostName logins.lcrc.anl.gov
  User username
  IdentityFile ~/.ssh/id_rsa

Host swing.lcrc.anl.gov swing
  HostName swing.lcrc.anl.gov
  ProxyJump logins.lcrc.anl.gov
  User username
  IdentityFile ~/.ssh/id_rsa

After configuring this, you can connect with either:

ssh swing.lcrc.anl.gov

or simply:

ssh swing

Note: The logins.lcrc.anl.gov alias is provided as part of LCRC's integration with CELS login infrastructure.
