# Reverse Engineering Notes
|
|
|
|
For this research, NLS Docker-Setup is used.
|
|
|
|
[TOC]
|
|
|
|
# Appliance
|
|
|
|
The instructions assume that Docker and NLS-Stack is installed.
|
|
|
|
## Get / Copy file structure
|
|
|
|
1. Create a target directory (e.g. `mkdir /opt/nls-files`)
|
|
2. Get the Container-ID of the NLS-Appliance (`docker ps`)
|
|
3. Copy files from container \
|
|
`docker cp -r <container-id->`
|
|
|
|
## About configuration data
|
|
|
|
- Most variables and configs are stored in `/var/lib/docker/volumes/configurations/_data`.
|
|
- Config-Variables are in `etc/dls/config/service_env.conf`.
|
|
|
|
## NLS Logs
|
|
|
|
Logs are found in `/var/lib/docker/volumes/logs/_data`.
|
|
|
|
Most interesting logs are:
|
|
|
|
- `fileInstallation.log`
|
|
- `serviceInstance.log`
|
|
|
|
## File manipulation
|
|
|
|
- Files can be copied with `docker cp <container-id>:/venv/... /opt/localfile/...`.
|
|
- Files can be directly edited via Docker-Volume mounts
|
|
- see `df -h` (one is nls, the other postgres container)
|
|
```
|
|
overlay 16G 11G 5.6G 66% /var/lib/docker/overlay2/<hash>/merged
|
|
overlay 16G 11G 5.6G 66% /var/lib/docker/overlay2/<hash>/merged
|
|
```
|
|
- then you can edit files with e.g. `nano venv/lib/python3.12/site-packages/...`
|
|
|
|
**After you edit any file directly, service needs to be restarted** `docker restart <container-id>`.
|
|
|
|
# Database
|
|
|
|
## DB Access
|
|
|
|
Valid users are `dls_writer` and `postgres`.
|
|
|
|
1. Log in to your Docker-Server
|
|
2. Get the Container-ID of the NLS-Postgres (`docker ps`)
|
|
3. Use psql \
|
|
`docker exec -it <container-id> psql -h localhost -U postgres`
|
|
4. (optional) Create a superuser for external access \
|
|
`CREATE USER admin WITH LOGIN SUPERUSER PASSWORD 'admin';`
|
|
5. Add exposed port to `docker-compose.yaml`
|
|
5.1 Add `ports: [ '5432:5432' ]` into `...`-section
|
|
|
|
## Table Structure
|
|
|
|
Some information about Database / Table structure can be found [here](Database.md).
|
|
|
|
# Logging / Stack Trace
|
|
|
|
- https://docs.nvidia.com/license-system/latest/nvidia-license-system-user-guide/index.html#troubleshooting-dls-instance
|
|
|
|
# Nginx
|
|
|
|
- NGINX uses `/opt/certs/cert.pem` and `/opt/certs/key.pem`
|
|
|
|
# Other tools / files
|
|
|
|
Other tools / files which may can helpful, but not known for what they are used.
|
|
|
|
**Appliance**
|
|
|
|
- `/etc/dls/config/site_key_uri.bin`
|
|
- `/etc/dls/config/dls_db_password.bin`
|
|
|
|
**Database**
|
|
|
|
- `/etc/dls/config/decryptor/decryptor`

## Check licensing status
|
|
|
|
- `nvidia-smi -q | grep "License"`
|
|
|
|
**Output**
|
|
|
|
```
|
|
vGPU Software Licensed Product
|
|
License Status : Licensed (Expiry: 2023-1-14 12:59:52 GMT)
|
|
```
|
|
|
|
## Track licensing progress
|
|
|
|
- NVIDIA Grid Log: `journalctl -u nvidia-gridd -f`
|
|
|
|
```
|
|
systemd: Started NVIDIA Grid Daemon.
|
|
nvidia-gridd: Configuration parameter ( ServerAddress ) not set
|
|
nvidia-gridd: vGPU Software package (0)
|
|
nvidia-gridd: Ignore service provider and node-locked licensing
|
|
nvidia-gridd: NLS initialized
|
|
nvidia-gridd: Acquiring license. (Info: license.nvidia.space; NVIDIA RTX Virtual Workstation)
|
|
nvidia-gridd: License acquired successfully. (Info: license.nvidia.space, NVIDIA RTX Virtual Workstation; Expiry: 2023-1-29 22:3:0 GMT)
