Expose Ollama on the LAN

Ollama binds 127.0.0.1:11434 by default. A LAN IP then returns connection refused. Set OLLAMA_HOST=0.0.0.0:11434 on that machine. Steps below are from the Ollama FAQ.

Leave Ollama on loopback if the upstream is http://127.0.0.1:11434 on the same box as orouta.

macOS

Section titled “macOS”

If you run the Ollama app, set the variable with launchctl, then restart the app:

Terminal window
launchctl setenv OLLAMA_HOST "0.0.0.0:11434"

Linux

Section titled “Linux”

If Ollama is a systemd service:

Terminal window
sudo systemctl edit ollama.service

Add:

[Service]
Environment="OLLAMA_HOST=0.0.0.0:11434"

Then:

Terminal window
sudo systemctl daemon-reload
sudo systemctl restart ollama

export in your shell does not change the systemd process.

Windows

Section titled “Windows”
  1. Quit Ollama from the taskbar.
  2. Open Settings (Windows 11) or Control Panel (Windows 10) and search for environment variables.
  3. Edit environment variables for your account.
  4. Create or edit OLLAMA_HOST with value 0.0.0.0:11434.
  5. OK/Apply, then start Ollama from the Start menu.

Check

Section titled “Check”

On the Ollama machine, curl http://127.0.0.1:11434/api/tags should work. From the orouta machine, curl http://<lan-ip>:11434/api/tags should work too. Then orouta will list that host’s models on the next tags refresh.
