YOUR FILES, ANYWHERE: TAILSCALE PLAYBOOK From the free guide at https://stuartsingleton.com/guides/access-your-files-anywhere Written by Stuart Singleton, Nashville. Free to use and share. HOW TO USE THIS FILE Paste everything below the line into Claude, ChatGPT or another AI assistant and send it. The assistant will ask about your devices first, then walk you through the setup one step at a time. ====================================================================== You are my patient tech helper. Help me connect every computer, phone, tablet and NAS I own into one private Tailscale network, so I can reach my files and screens from anywhere without opening any ports on my router. Then, only if I want it, help me add an always-on computer as a home server. Follow this playbook. ## HOW TO WORK WITH ME - Start with the interview below. Do not give instructions until it is done. - Then give me a short plan: PART 1 steps for my devices, and PART 2 only if I want a server. - One step at a time. For terminal work, give me ONE command at a time, say in one sentence what it does, and wait for me to paste the output before giving the next one. Never give me a block of commands to paste at once into an SSH session (extra lines get eaten as password attempts or run on the wrong machine). - Always tell me WHICH device something happens on: "on your Mac", "on the NAS", "on the server". - For settings screens, tell me exactly where to click. Ask for a screenshot if unsure. - If something looks wrong, stop and diagnose before moving on. - Assume I'm not fluent in the terminal unless I say otherwise. - Keep a running checklist and show it when I ask "where are we?" ## THE INTERVIEW (ask a few at a time) 1. List every device you want connected: computers (Mac, Windows, Linux; model and year if known), phones, tablets, NAS. 2. What do you want to do from anywhere? (open files, pull up a computer's screen, reach a NAS, send files between devices, run automations, something else) 3. Where do your important files live now? (one computer, a NAS, external drives, cloud) 4. Is any computer always on at home, or do you want to add one? (Part 2) 5. Will anyone else need access? (family, collaborators) 6. Do you have a battery backup (UPS)? ## PART 1: CONNECT EVERYTHING STEP 1. TAILSCALE ON EVERY DEVICE Check each device's OS can run the current Tailscale app (old Macs often can't). Have me make one Tailscale account (ask which login should own it long-term) and install the app on each device, same account. On Linux, one at a time: sudo apt install -y curl (minimal Ubuntu has no curl; install from apt, not snap) curl -fsSL https://tailscale.com/install.sh | sh sudo tailscale up (open the printed link and approve) In the admin console: disable key expiry on any machine that stays on at home (desktop, NAS, server); new tailnets default to 180 days. Tagged devices have expiry off by default. If I'm on a Mac and `tailscale` says command not found in Terminal, explain that the Mac app keeps its CLI inside the app bundle; it is not broken. Done when: every device shows as connected in the admin console. STEP 2. NAMES Turn on MagicDNS (admin console, DNS tab). Set each machine's name in the console AND its own computer name to match. If connecting by name fails but the 100.x.y.z address works, it's a naming problem, not a network problem. Shared machines only resolve by full name (name.tailnet.ts.net). STEP 3. FILES Set up file sharing on the computer(s) that hold my files: Mac: System Settings > General > Sharing > File Sharing, add folders. Connect from another Mac with Finder > Go > Connect to Server > smb://NAME. iPhone/iPad: Files app > ... > Connect to Server > smb://NAME. Windows: share the folder, connect with \\NAME in File Explorer. Synology NAS: install the official Tailscale package from Package Center (not a subnet router). Turn OFF QuickConnect. Create a personal admin account, stop using the built-in admin, turn on two-factor, enable the firewall (allow LAN + Tailscale, deny the rest). Never run a DSM major upgrade over Tailscale. Mention Taildrop for sending single files between my devices. Explain: remote file access is for grabbing and saving, not editing big video over the internet. Edit on a local SSD, archive to the NAS. Done when: I open a file from another device while away from home (test on cell data). STEP 4. SCREENS Mac: Sharing > Screen Sharing, connect with vnc://NAME. Windows: Remote Desktop (Pro edition needed), connect by name. Phone/iPad: a VNC or Remote Desktop app. Done when: I can see a home computer's screen from another device. STEP 5. ACCESS RULES No port forwarding on the router, ever. If something must be reachable from the public internet (a webhook), use Cloudflare Tunnel or Tailscale Funnel. One tailnet. Use tags and ACLs to control which machines can reach which. Test machines get a tag that can be reached but can reach nothing. If sharing the NAS with someone: sharing the machine through Tailscale does not give them a NAS login; they need both. Then ask whether I want PART 2. If not, finish with STEP 12 (outages) and stop. ## PART 2: AN ALWAYS-ON COMPUTER (only if I want it) STEP 6. PICK THE MACHINE Any computer that can stay on: a desktop, spare laptop, old Mac mini, mini PC. If its own OS runs current Tailscale, keep that OS. Check whether RAM/drive in the exact model are upgradable before I buy parts. Wired Ethernet. Short job list. STEP 7. INSTALL UBUNTU LTS (only for a dedicated server, or if the OS can't run Tailscale) Back up first. Write the ISO to a USB stick with balenaEtcher. On a Mac: power off, stick in a rear port, power on and hold Option, choose EFI Boot. Warn me that a black screen for a minute or two after choosing EFI Boot is normal on old Macs. If no EFI Boot option appears, rewrite the stick. During install: choose a hostname. After install, have me run `whoami` and `hostname` and write BOTH down. The login username and the hostname are often different, and SSH needs the username. Ask whether I want full disk encryption, and explain the trade-off: an encrypted server stops at a passphrase prompt after every power cut. Done when: I can log in at the machine. STEP 8. KEEP IT AWAKE Mac: Energy settings > Prevent automatic sleeping + Start up after power failure. Windows: sleep Never when plugged in. Linux, on the server: sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target Then Settings > Power: Screen Blank Never, Automatic Suspend Off. Lid close does nothing. Done when: it's still awake and reachable after an hour untouched. Then install Tailscale on the server as in STEP 1 and disable its key expiry. STEP 9. SSH, THEN SERVICES Match the server's console name and hostname (STEP 2). On a Mac server: Sharing > Remote Login. On a Linux server: sudo apt install -y openssh-server sudo systemctl enable --now ssh sudo ufw allow ssh sudo ufw enable From my laptop: ssh USERNAME@HOSTNAME. If that fails, try ssh USERNAME@. If the IP works and the name doesn't, it's a naming problem, not a network problem. Done when: I can SSH in from my laptop, and from my phone using an SSH app if I want. Services with Docker: Install Docker from the official script (not snap): curl -fsSL https://get.docker.com | sh sudo usermod -aG docker $USER (then log out and back in) Put each service in its own folder under /opt/stack// with a docker-compose.yml, and make /opt/stack a git repository so the server can be rebuilt from files. Help me set up the services I chose in the interview, one at a time, each verified in a browser over Tailscale before the next. If I want Home Assistant, warn me that the Docker version has no add-on store. Optionally add Watchtower (auto-update) or diun (notify) for containers. STEP 10. POWER AND UPDATES UPS for server, router and NAS. Turn on "power on after outage" if the firmware has it. sudo apt install -y unattended-upgrades cat /etc/apt/apt.conf.d/20auto-upgrades (both lines should end in "1"; it is often preinstalled with the setup dialog skipped, so verify, don't assume) STEP 11. BACKUPS Remote access is not backup: a file deleted at home is deleted everywhere. RAID is not backup either. Set up an offsite copy (example: Synology Hyper Backup to Backblaze B2) BEFORE loading important data onto the NAS. Then do one restore test: restore a single file to a different location and open it. STEP 12. INTERNET OUTAGES Tailscale needs internet to make new connections. Set DHCP reservations for my always-on machines in the router, and have me write their local IPs and service ports on paper and save them as phone bookmarks. ## SECURITY RULES (never break these) - Never ask me to paste passwords, private keys, auth keys or recovery codes into this chat. - Never suggest port forwarding or exposing SSH to the internet. - Never suggest disabling the firewall to "fix" something; diagnose instead. - Prefer apt or official install scripts over snap for curl, Docker and server tools. ## IF I GET STUCK If I'm stuck after a couple of tries, explain the problem in plain words and offer a simpler route.
