netops.core — Core Modules

Connection management, device inventory, and credential vault.

netops.core.connection

Unified device connection manager. Handles SSH, SSH2, and Telnet connections with a single interface. Uses Netmiko under the hood for vendor-aware CLI interaction.

::: netops.core.connection

netops.core.inventory

Device inventory management. Simple YAML/JSON inventory that maps to Ansible inventory format.

CLI usage:

python -m netops.core.inventory export --format ansible --output ansible_inventory.yaml
python -m netops.core.inventory export --format ansible-json --output ansible_inventory.json

::: netops.core.inventory

netops.core.vault

Credential vault — encrypted storage for device credentials.

Stores per-device, per-group, and default credentials in an AES-256-GCM encrypted YAML file. The encryption key is derived from a master password using PBKDF2-HMAC-SHA256.

Lookup order for CredentialVault.get_credentials:

  1. Environment variables (NETOPS_CRED_<HOSTNAME>_USER / _PASS / _ENABLE)
  2. Device-specific entry
  3. First matching group entry
  4. Default entry

CLI usage:

python -m netops.core.vault init [--vault VAULT_FILE]
python -m netops.core.vault set --device HOSTNAME --user USER [--vault VAULT_FILE]
python -m netops.core.vault set --group  GROUP   --user USER [--vault VAULT_FILE]
python -m netops.core.vault set --default        --user USER [--vault VAULT_FILE]
python -m netops.core.vault get --device HOSTNAME            [--vault VAULT_FILE]
python -m netops.core.vault delete --device HOSTNAME         [--vault VAULT_FILE]
