To connect your local machine to the eRI cluster a Secure Shell (SSH) connection needs to be established. If you are using a Unix-like operating system like MacOS or Linux this can be achieved simply using the inbuilt terminal. Windows users must make use of an SSH client (e.g. WSL, PuTTY, MobaXterm).

For NeSI staff access please follow these instructions, all others see next set of Instructions:

1. First copy the following SSH host configs you can rename the login nodes I justnnamed them eri-X as their true hostnames are generic login-X:

Host bastion
   User nesi-support
   Hostname 163.7.177.182
   ServerAliveInterval 300
   ServerAliveCountMax 2

Host eri-0
   User USER
   Hostname 10.29.107.20
   ProxyCommand ssh -W %h:%p bastion
   ServerAliveInterval 300
   ServerAliveCountMax 2
   #ForwardX11 yes
   #ForwardX11Trusted yes

Host eri-1
   User USER
   Hostname 10.1.112.21
   ProxyCommand ssh -W %h:%p bastion
   ServerAliveInterval 300
   ServerAliveCountMax 2

2. Second, send one of your public keys to someone that already has access so they can add it to:

/home/nesi-support/.ssh/authorized_keys

3. Login to one of the eri login nodes with passwd provided by platforms and I recommend adding your personal pubkey auth to avoid passwords altoghether, eg from Mahuika:

$ ssh-copy-id -i ~/.ssh/mypubkey.pub eri-0
