ssh username@sol.cc.lehigh.edu

If you are off campus, then there are two options

1. Start a vpn session and then login to Sol using the ssh command above
2. Use ssh gateway as a jump host first and then login to Sol using the above ssh command on the ssh gateway prompt. If your ssh is from the latest version of openssh, then you can use the following command

ssh -J username@ssh.cc.lehigh.edu username@sol.cc.lehigh.edu

If you are using the ssh gateway, you might want to add the following to your ${HOME}/.ssh/config file on your local system

  Host *ssh
  HostName ssh.cc.lehigh.edu
  Port 22
# This is an example - replace alp514 with your Lehigh ID
  User alp514

  Host *sol
  HostName sol.cc.lehigh.edu
  Port 22
  User <LehighID>
#  ProxyCommand ssh ssh nc %h %p
  ProxyCommand ssh -W %h:%p ssh

to simplify the ssh and scp (for file transfer) command. You will be prompted for your password twice - first for ssh and then for sol

ssh sol
scp sol:<path to source directory>/filename <path to destination directory>/filename 

If you are using public key authentication, please add a passphrase to your key. Passwordless authentication is a security risk. Use ssh-agent and ssh-add to manage your public keys. See https://kb.iu.edu/d/aeww for details.

Windows users will need to install a SSH Client to access Sol. Lehigh Research Computing recommends MobaXterm since it can be configured to use the SSH Gateway as jump host. DUO Authentication is activated for faculty and staff on the SSH Gateway. If a window pops up for password enter your Lehigh password. The second pop up is for DUO, it only says DUO Login. Enter 1 for Push to DUO or 2 for call to registered phone.
