FastAPI-DLS
Minimal Delegated License Service (DLS).
Compatibility tested with official DLS 2.0.1.
This service can be used without internet connection. Only the clients need a connection to this service on configured port.
[[TOC]]
ToDo's
- Support http mode for using external https proxy (disable uvicorn ssl for using behind proxy)

Now you have to run systemctl daemon-reload. After that you can start service
with systemctl start fastapi-dls.service and enable autostart with systemctl enable fastapi-dls.service.
Debian/Ubuntu (using dpkg)
Packages are available here:
Successful tested with:
- Debian 12 (Bookworm) (works but not recommended because it is currently in testing state)
- Ubuntu 22.10 (Kinetic Kudu)
Run this on your server instance
First go to GitLab-Registry and select your
version. Then you have to copy the download link of the fastapi-dls_X.Y.Z_amd64.deb asset.
apt-get update
FILENAME=/opt/fastapi-dls.deb
wget -O $FILENAME <download-url>
dpkg -i $FILENAME
apt-get install -f --fix-missing
Start with systemctl start fastapi-dls.service and enable autostart with systemctl enable fastapi-dls.service.
ArchLinux (using pacman)
Shout out to samicrusader who created build file for ArchLinux!
Packages are available here:
pacman -Sy
FILENAME=/opt/fastapi-dls.pkg.tar.zst
url -o $FILENAME <download-url>
pacman -U --noconfirm fastapi-dls.pkg.tar.zst
Start with systemctl start fastapi-dls.service and enable autostart with systemctl enable fastapi-dls.service.
Let's Encrypt Certificate
If you're using installation via docker, you can use traefik. Please refer to their documentation.
Note that port 80 must be accessible, and you have to install socat if you're using standalone mode.
acme.sh --issue -d example.com \
--cert-file /etc/fastapi-dls/webserver.donotuse.crt \
--key-file /etc/fastapi-dls/webserver.key \
--fullchain-file /etc/fastapi-dls/webserver.crt \
--reloadcmd "systemctl restart fastapi-dls.service"
After first success you have to replace --issue with --renew.

*1 For example, if the lease period is one day and the renewal period is 20%, the client attempts to renew its license every 4.8 hours. If network connectivity is lost, the loss of connectivity is detected during license renewal and the client has 19.2 hours in which to re-establish connectivity before its license expires.
*2 Always use https, since guest-drivers only support secure connections!
Setup (Client)
The token file has to be copied! It's not enough to C&P file contents, because there can be special characters.

Windows
Required cipher on Windows Guests (e.g. managed by domain controller with GPO)
It is required to enable SHA1 (TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P521)
in windows cipher suite.
Multiple Display Container LS Instances
On Windows on some machines there are running two or more instances of NVIDIA Display Container LS. This causes a
problem on licensing flow. As you can see in the logs below, there are two lines with NLS initialized, each prefixed
with <1> and <2>. So it is possible, that daemon 1 fetches a valid license through dls-service, and daemon 2
only
gets a valid local license.

Error on releasing leases on shutdown
The driver wants to release current leases on shutting down windows. This endpoint needs to be a http endpoint and is currently not implemented. The error message looks like and safely can be ignored (since we have no license limitation :P):
<1>:NLS initialized
<1>:License acquired successfully. (Info: 192.168.178.110, NVIDIA RTX Virtual Workstation; Expiry: 2023-3-30 23:0:22 GMT)
<0>:Failed to return license to 192.168.178.110 (Error: Generic network communication failure)
