How to access the cluster
ssh username@euler.ethz.ch ssh username@login.leonhard.ethz.ch
ssh -Y username@euler.ethz.ch ssh -Y username@login.leonhard.ethz.ch |
For new users and unverified accounts
An access code has been sent to your ETH email address. Enter the access code at the prompt below. If you do not receive the access code within a few minutes, then contact us by opening a ticket at http://smartdesk.ethz.ch Access code (ending in ******Ls): |
External collaborators
Members of other institutions who have a collaboration with a research group at ETH may use the clusters for the purpose of said collaboration
- Their counterpart (“sponsor”) at ETH can create an ETH guest account, e-mail address and VPN service for them
- Then, they can access Euler like members of ETH
Firewall
- To connect from outside of the ETH network to the clusters, establish first a VPN connection. Then, connect to the cluster through SSH.
- To connect to an external service from a compute node, use the ETH proxy service:
module load eth_proxy
Legal Compliance
The HPC clusters are subject to ETH’s acceptable use policy for IT resources (Benutzungsordnung für Telematik (BOT)), in particular:
- Cluster accounts are strictly personal
- DO NOT share your account (password, sshkeys) with anyone
- DO NOT use someone else’s account, even if they say it’s OK
- If you suspect that someone used your account, change your password and contact cluster-support@id.ethz.ch
Consequences:
- In case of abuse, the offender’s account may be blocked temporarily or closed
- System administrators are obliged by law to investigate abusive or illegal activities and report them to the relevant authorities
