# Bare Metal Quickstart *** Your node has Linux (Ubuntu) OS. It comes pre-loaded with some tools to simplify your set-up process. ## Connecting to Your Node When your bare metal node is ready, you will be provided its username and IP address. To connect to your node, use the following command on a device with one of the SSH keys: ```bash ssh [username]@[ip_address] ``` This command will be your primary method of accessing and managing your node. *** ## Node Basics Your node comes with Ubuntu 22.04 LTS and ROCm. All SSH keys you've initially provided will have root user access. ### Adding More SSH Keys In the event that you would like to provide more users SSH access to your node, follow these steps: 1. Copy your key, which should be structured like: ``` ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDxAZn... user@host ``` 2. SSH into your node using: ```bash ssh [username]@[ip_address] ``` 3. Open your authorized keys file using: ```bash nano /home/[username]/.ssh/authorized_keys ``` 4. Paste your key at the bottom of the file 5. Save and exit 6. Restart the sshd service using: ```bash sudo systemctl restart sshd ``` ### Monitoring Your GPUs To get more information on your GPUs, use `rocm-smi` in your terminal. To continue to monitor this, you can run `watch -n 0.5 rocm-smi`. This will provide information on both IDs and usage in intervals of 0.5 seconds, as shown below: ``` ============================================ ROCm System Management Interface ============================================ ====================================================== Concise Info ====================================================== Device Node IDs Temp Power Partitions SCLK MCLK Fan Perf PwrCap VRAM% GPU% (DID, GUID) (Junction) (Socket) (Mem, Compute, ID) ========================================================================================================================== 0 2 0x74a1, 39334 45.0°C 142.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 1 3 0x74a1, 34119 42.0°C 135.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 2 4 0x74a1, 664 42.0°C 137.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 3 5 0x74a1, 33001 48.0°C 142.0W NPS1, SPX, 0 154Mhz 900Mhz 0% auto 750.0W 0% 0% 4 6 0x74a1, 15994 46.0°C 143.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 5 7 0x74a1, 63627 40.0°C 137.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 6 8 0x74a1, 33811 47.0°C 143.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% 7 9 0x74a1, 41883 42.0°C 132.0W NPS1, SPX, 0 132Mhz 900Mhz 0% auto 750.0W 0% 0% ========================================================================================================================== ================================================== End of ROCm SMI Log =================================================== ``` ### Downloading and Uploading Files To download files from your server, use the `scp` command: ```bash // For individual files scp [username]@[ip_address]:/path/to/remote/file /path/to/local/destination // For subdirectories scp -r [username]@[ip_address]:/path/to/remote/directory /path/to/local/destination ``` To upload files to your server, you may also use the scp command: ```bash // For individual files scp /path/to/local/file [username]@[ip_address]:/path/to/remote/destination // For subdirectories scp -r /path/to/local/file [username]@[ip_address]:/path/to/remote/destination ``` ### Accessing Remote Services Locally Often times, you will find yourself needing to access a service being exposed on your remote server, locally. To do so, use the following command: ```bash ssh -L local_port:remote_host:remote_port [username]@[ip_address] ``` For example, let's assume you want to access a Jupyter Notebook that you've exposed on port 8888. From your **local** command line, you'll want to use the following: ```bash ssh -L 8888:localhost:8888 [username]@[ip_address] ``` Then, you can access this in your browser at [http://localhost:8888
](http://localhost:8888). ***
