# NetworkManager Connection Sync Script A script to Sync wifi passwords between machines. This repository contains a simple set of shell commands used to **export, sanitize, and re‑import NetworkManager connection profiles** between a local system and a shared location. It is intended for **Linux systems using NetworkManager** (e.g. Debian, Ubuntu, RHEL-family). --- ## Purpose - Back up NetworkManager *.nmconnection* profiles to a shared directory - Remove host-specific fields (*interface-name*, *uuid*) - Restore the cleaned profiles onto another system - Reload NetworkManager connections safely This allows reuse of connection profiles across machines without UUID or interface conflicts. --- ## Directory Structure ``` . └── Connections/ └── system-connections/ ``` The *Connections/system-connections/* directory must exist before running the export step. --- ## Script Logic ### 1. Copy connections from local system to share Shell Show more lines - Copies all NetworkManager connection profiles - Temporarily relaxes permissions to allow editing and sharing --- ### 2. Clean and rebuild connections from share to local Shell Show more lines Removes fields that **must be regenerated per-host**: - *interface-name* (hardware specific) - *uuid* (must be unique per system) --- Shell Show more lines - Restores profiles to the correct system location - Applies required ownership and permissions for NetworkManager --- ### 3. Reload NetworkManager Shell Show more lines Reloads all connection profiles without restarting the NetworkManager service. --- ## Requirements - Linux with **NetworkManager** - *nmcli* - Root (sudo) access - *.nmconnection* files (keyfile format) --- ## Safety Notes - **Do not keep */etc/NetworkManager/system-connections/* world-writable** - Permissions **must** be: - Mode: *600* - Owner: *root:root* - Failure to do so may cause NetworkManager to ignore the profiles Reference: - NetworkManager keyfile permissions documentation --- ## Typical Use Cases - Provisioning identical network configs across multiple hosts - Migrating Wi‑Fi / VLAN / VPN profiles - Lab or cluster deployments - Backup and restore of NetworkManager configs --- ## Tested With - Debian / Ubuntu - NetworkManager keyfile backend - Wired, Wi‑Fi, VLAN, and VPN profiles
