Music, Song & SSH

Remote Access: Connecting from FreeBSD to NetBSD to Stream Your Music

Practical, secure, and efficient: how to access your NetBSD server while traveling, using your FreeBSD laptop.

Scenario

You are traveling with your FreeBSD laptop and suddenly want to access your home NetBSD server where you host your music collection. Here’s how to securely and efficiently set up remote access between these two BSD systems.

Solution: SSH + Remote Filesystem Mount (SSHFS)

1. Configure the NetBSD Server (At Home)

1. Ensure SSH is enabled: sshd=YES Add this to /etc/rc.conf, then start the service: /etc/rc.d/sshd start
2. Configure your firewall: Ensure that port 22/TCP is open for incoming connections.
3. Set up Dynamic DNS (optional): If you don’t have a static IP, use a service like DuckDNS or No-IP to create a dynamic DNS hostname.
4. Set up SSH key authentication: ssh-keygen -t ed25519 Then copy your public key to the NetBSD server: ssh-copy-id user@netbsd-server

2. On Your FreeBSD Laptop (While Traveling)

1. Connect via SSH: ssh user@your_public_ip_or_dns  Now you have terminal access to your NetBSD server.
2. Install SSHFS: pkg install sshfs
3. Create a mount point: mkdir ~/netbsd-music
4. Mount the remote directory: sshfs user@your_public_ip_or_dns:/path/to/music ~/netbsd-music  Your NetBSD music collection is now accessible locally on your FreeBSD laptop.

3. When Finished

Unmount the remote directory with:

fusermount -u ~/netbsd-music

Security Tips

• Use SSH key authentication only — disable PasswordAuthentication in /etc/ssh/sshd_config.
• Consider using a non-standard port (e.g., 2222) for added security.
• Enable rate limiting or tools like fail2ban to prevent brute-force attacks.

Summary

NetBSD: Enable SSH, configure firewall, optionally set up DDNS.

FreeBSD: Connect via SSH, mount remote directory with SSHFS.

Result: Stream and play your music collection as if it were stored locally.
