Guide to Use Talamus

Facility BioData Hub

1 Introduction

In this guide you will find the main procedures for accessing the server, transferring files, running jobs and managing resources.

2 Server Access

2.1 Creating an SSH ed25519 Key

After your account has been created on the BioData Hub server, you must complete the following two steps to register each computer that will need to connect to the server.

To generate a secure SSH key open a terminal on your local computer and run:

# Generate a new ed25519 key
ssh-keygen -t ed25519

# You will be asked where to save it (default: ~/.ssh/id_ed25519)
# You can also protect the key with a passphrase

✅ Note: After generating your key, contact us so we can add your public key to the server.

SSH (Secure Shell) is a protocol that allows you to securely connect to a remote server over an encrypted channel. An SSH key is a pair of cryptographic files (a private key and a public key) used to authenticate your identity without needing to type a password each time.

⚠️ Warning: Never share your private key (id_ed25519) — only share the public one (id_ed25519.pub)!

2.2 First Commands to Use

Action	Command / Instruction
Connect via SSH	ssh user@server_address
Logout	exit
Check current working directory	pwd

To connect to BioData Hub Server open a prompt shell and write:

ssh -p 2323 username@147.162.3.228
