Scan your network and populate info to Netbox, fast and reliable
Report Bug · Request Feature

The project is meant to be as stable as robust as possible. There's a reason behind Netbox project not wanting to create a scanner, if you use Netbox it is recommended to be your source of truth. In order to make that statement true we need to make sure Netbox doesn't contain outdated, not acurate or not useful info. This script aims to keep things as simple as possible and pre-populate info into Netbox to make your life easier.

It's recommended to first run the script pointing at a dev instance of Netbox first. This project tries to populate info in a safe way but there's never 100% certainty and things can get ugly if you run this script directly in prod and something goes wrong. Because automated source of truth can be handy sometimes ;-)

• Python
• PyNetbox
• python3-nmap

To get a local copy up and running follow these simple steps.

This script works with Netbox >= 2.9 and python >=3.6 In order to run the software you just need to install the requirement.

• python >= 3.6

  pip install -r requirements.txt

1. Clone the repo

   git clone https://github.com/guanana/netbox-sync-physical-hosts.git

2. Install python packages

pip install -r requirements.txt

The script can be run with multiple configuration options. Most of the configuration options can be overwrite using environment variables

[GENERAL]
cleanup: false
tag: nmap-sync

[NETBOX]
nb_url: http://your-server-here:your-port-here
nb_token: your-token-here
nb_ignore-tls-errors: false

[NMAP]
get_mac: true
get_services: false
networks: your-networks-separated-by-comma-here ie: (192.168.4.0/24,192.168.3.0/24)

export NETBOX_URL=http://your-server-here:your-port-here
export NETBOX_TOKEN=your-token-here
export NETWORKS=your-networks-separated-by-comma-here

Be aware that if you activate get service option it will take between 15sec and 30sec per host (so it can be slow)

This service is pretty fast but will only work if the scan is performed from the same subnet ie: scanning subnet 192.168.1.0/24 from 192.168.1.2

 python netbox-sync.py --help
usage: netbox-sync.py [-h] [-c CONFIG] -u NB_URL [-l L] -p NB_TOKEN [-x] [-f] [-t TAG] -n NETWORKS [-o] [-s]

Args that start with '--' (eg. -u) can also be set in a config file (./Netbox-sync-physical-hosts/netbox-sync-physical-hosts/netbox-
sync.conf or specified via -c). Config file syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax at https://goo.gl/R74nmi). If an arg is specified
in more than one place, then commandline values override environment variables which override config file values which override defaults.

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Config file path
  -u NB_URL, --nb_url NB_URL
                        Netbox URL [env var: NETBOX_URL]
  -l L                  log level [env var: LOG_LEVEL]
  -p NB_TOKEN, --nb_token NB_TOKEN
                        Token for Netbox connection [env var: NETBOX_TOKEN]
  -x, --nb_ignore-tls-errors
                        Ignore TLS conection errors
  -f, --cleanup         Cleanup orphans
  -t TAG, --tag TAG     Tag to use for device identification [env var: TAG]
  -n NETWORKS, --networks NETWORKS
                        Networks/Hosts to scan [env var: NETWORKS]
  -o, --get_mac         Enable if you want the script to try to collect MAC addresses/vendor [env var: MAC_DISCOVER]
  -s, --get_services    Enable if you want the script to discover host services [env var: SERVICE_DISCOVER]
