TUM Test Instance

The test instance runs on logos-test.aet.cit.tum.de. You need the TUM VPN and SSH access to the server.

Web Application and API

Port 443 serves the web application, the Swagger UI and the API. Traefik routes by path. API paths (/v1, /openai, /jobs, /api, /docs, and others) go to the API. All other paths go to the web application.

Purpose	URL
Web application	https://logos-test.aet.cit.tum.de/
Swagger UI	https://logos-test.aet.cit.tum.de/docs

GET /v1 returns 404. This is correct. Use /docs to see the endpoints. Port 8080 is a TLS alias for the completion API. It is only for clients that use it already.

SSH

1. Request Artemis developer access.

2. Connect to the TUM VPN.

3. Connect to the server with your TUM ID:

   ssh <tum-id>@logos-test.aet.cit.tum.de

The Logos installation is in /opt/logos on the server.

Database

PostgreSQL does not accept connections from outside the server. Use an SSH tunnel.

To use a manual tunnel:

1. Open the tunnel:

   ssh -L 5433:127.0.0.1:5432 <tum-id>@logos-test.aet.cit.tum.de

2. Connect your database client to localhost:5433. Use the values in the table below.

Field	Value
Database	logosdb
Username	postgres
Password	root

To use DBeaver:

1. Create a PostgreSQL connection.
2. On the SSH tab, set these values:
   • Host/IP: logos-test.aet.cit.tum.de
   • Port: 22
   • User Name: your TUM ID
   • Authentication: Public Key
   • Private Key: the path to your SSH private key, for example ~/.ssh/id_ed25519
3. On the Main tab, set Host to localhost and Port to 5432.
4. Set the database, the username and the password from the table above.
