omarchy alias in ~/.ssh/config with key-based auth, and appends the alias if it is missing. - Failure diagnosis: Distinguishes wrong-user errors, dead LAN addresses, MagicDNS resolution failures, and offline Tailscale nodes before retrying. - Remote execution patterns: Runs one-off commands, long-lived tmux sessions, rsync file transfers, and remote Claude agents on the second box. - Use Case: You ask to start a long build on the other machine. The Skill checks the node is online via tailscale status, launches the build inside tmux over SSH, and reads the output back with tmux capture-pane. ## Quick Start Ask the assistant to run a command on the second computer, for example: check uptime on PC2 and report back what the box answered.High-intent search queries and answers about installing and using this skill.
Add a Host entry in ~/.ssh/config pointing to the machine's Tailscale IP with the correct user, then run ssh <alias>. Key-based authentication with an authorized ed25519 key avoids any password prompt.
Start the command inside tmux on the remote host with ssh host 'tmux new -d -s name "command"' so it survives the SSH session. Read output later with ssh host 'tmux capture-pane -p -t name'.
The login username is likely wrong, not the password. On this Omarchy box the user is nc, not nadavcohen, and every attempt as nadavcohen is rejected regardless of password.
MagicDNS names fail when the system resolver is not pointed at Tailscale, even though tailscale status shows the node. Use the node's Tailscale IP address directly instead of the hostname.
Run tailscale status and grep for the node name to confirm it is not marked offline, then ping its Tailscale IP. If the node is offline the machine is asleep or off, so do not retry SSH.
Yes, use rsync over SSH with the remote alias, for example rsync -av local-path omarchy:remote-path. Both machines need rsync installed, and the same key-based SSH authentication applies.
