How To Login To Acres

SSH

Access to Acres is limited to a few connection points, and is tightly controlled. SSH is the only way to access Acres, with most networks having access by pivoting through Polaris.

Windows, Linux, or Mac Terminal

From most terminals, SSH is installed by default. SSH access to Polaris can simply be done through the terminal by using ssh acres.clarkson.edu.

However, since Acres is extremely locked down, you may need to 'jump' through Polaris when on a more restricted network. For accessing Polaris, see this bookstack article. From Polaris, you should be able to SSH to Acres directly.

To make this jump automated, use the -J flag, so ssh acres.clarkson.edu becomes ssh -j polaris.clarkson.edu acres.clarkson.edu.

To make this permanent, an SSH Config can be created on the host you are SSHing from.

# This file is at ~/.ssh/config

Host polaris polaris.clarkson.edu
  Hostname polaris.clarkson.edu

Host acres acres.clarkson.edu
  Hostname acres.clarkson.edu
  ProxyJump polaris

Once this config is in place, a simple ssh acres should automatically jump you through Polaris into Acres.

Other Methods

All methods to access Acres are done the same as Polaris, only using Polaris as the ProxyJump. SSH Keys, Duo Auth, File transfer, all of that can be done through the ProxyJump.
