Passwordless SSH

Set up SSH keys to connect without a password.

less than a minute

Generate an SSH key (on your local machine)

$ ssh-keygen -t ed25519 -C "your.email@tudelft.nl"

Press Enter to accept defaults. Optionally set a passphrase.

Copy your public key to DAIC

$ ssh-copy-id <YourNetID>@daic01.hpc.tudelft.nl

$ ssh <YourNetID>@daic01.hpc.tudelft.nl

You should connect without entering a password.

Kerberos for network storage

Important

SSH key login does not create a Kerberos ticket. Without a ticket, you cannot access network storage (~/linuxhome, project storage, etc.).

After connecting with SSH keys, run:

$ kinit
Password for <YourNetID>@TUDELFT.NET:

Verify your ticket:

$ klist
Ticket cache: KCM:656519
Default principal: <YourNetID>@TUDELFT.NET

Valid starting     Expires            Service principal
03/23/26 11:05:12  03/23/26 21:05:12  krbtgt/TUDELFT.NET@TUDELFT.NET

First access delay

Network storage may take up to 30 seconds to mount on first access. If you see “Stale file handle”, wait and retry.

SSH config shortcut

Add to ~/.ssh/config on your local machine:

Host daic
    HostName daic01.hpc.tudelft.nl
    User <YourNetID>

Then connect with just:

$ ssh daic
