Configure your computer to be a server (advanced)¶
Note
This page assumes you have already installed the oTree server, as described on the server setup pages for Windows/Mac (see here).
If you will be running your study with devices on the local network (e.g. your university network) and don’t need access from the internet, you can follow the below steps to use your own computer as a server.
Windows¶
Create a firewall rule (Windows only)¶
You need to allow other computers to connect to oTree through your firewall.
Open the Windows Firewall
Go to “Inbound Rules”
Click “New Rule”
Select “Port” to make a port rule
Under “Specific local ports”, enter 80 and 8000
Select “Allow the connection”
Click “next” then choose a name for your rule (e.g. “oTree”).
Find your IP address (Windows)¶
Open PowerShell or Command Prompt and enter ipconfig.
Look for the entry IPv4 Address.
Maybe it will look something like 10.0.1.3, or could also start with 172 or 192.
MacOS¶
Find your IP address (MacOS)¶
Go to “System Preferences” > “Network”, and select the network you’re using.
Depending on your version of macOS, you may have to click “Advanced” > “TCP/IP”
to view your IP address.
Maybe it will look something like 10.0.1.3, or could also start with 172 or 192.
Run the server¶
Start the server with your IP address and port 8000, e.g.
otree devserver 10.0.1.3:8000.
Note
We are just using devserver as a temporary step.
Once you have these steps working, you should switch to using the
production server otree runprodserver.
On the client device’s browser, connect to the IP address followed by :8000,
e.g. 10.0.1.3:8000 and you should be able to load the oTree demo page.
Make sure your IP address doesn’t change¶
In most university networks, your internal IP address will generally stay the same, as long as you stay connected to the same network. If it changes unpredictably, you can ask your IT department to add a rule on their DHCP server to always assign the same IP to your computer.
