Getting started

Run a server

curl -s -O https://raw.githubusercontent.com/unioslo/nivlheim/master/docker-compose.yml
docker-compose up -d

At this point, there's no data in the system, because no clients have been configured yet.

Run the client

This project used to provide rpms, but that function has been discontinued. We still maintain an rpm spec file for the client, which is included in the repo. It is up to you to decide how to package and distribute the client.

Example: How to use the client on Fedora 35:

1. Grab the code and the required libraries:

sudo dnf install -y perl openssl dmidecode \
	perl-Archive-Tar perl-File-Basename perl-File-Path perl-Getopt-Long \
	perl-HTTP-Message perl-IO perl-IO-Socket-INET6 perl-Net-DNS \
	perl-Sys-Hostname perl-Sys-Syslog perl-Socket perl-YAML-LibYAML
git clone https://github.com/unioslo/nivlheim.git

2. Create a config file

sudo mkdir /etc/nivlheim /var/nivlheim
sudo cp nivlheim/client/client.yaml /etc/nivlheim
echo "  server: localhost" | sudo tee -a /etc/nivlheim/client.yaml

3. (Optional) Whitelist the IP range the client will be coming from:

curl -sS -X POST 'http://localhost:4040/api/v2/settings/ipranges' -d 'ipRange=172.16.0.0/12'

4. Run the client

sudo nivlheim/client/nivlheim_client --debug

5. (Optional) manually approve the client

If the IP address wasn't whitelisted, the server will require you to manually approve the new machine before data is processed. On the web admin pages the new machine will show up as waiting for approval. After it has been approved, and the client has run one more time, data from it will start showing up in the system.

6. (Optional) Configure a cron job for the client:

sudo cp nivlheim/client/cronjob /etc/cron.d/

Next steps

If you are using a self-signed certificate for the web server (by default the nivlheim server container will create one for itself), then the CA certificate file must be distributed to the clients. Copy /var/www/nivlheim/CA/nivlheimca.crt from the server, and place it in /var/nivlheim on the machine you're installing the client software on.
