About:
Rancid is a network configuration monitoring tool that automatically logs into network devices via SSH or Telnet, retrieves their configurations, and stores them in a version control system. It detects and emails changes to device configurations, providing a detailed diff for review. This enables network administrators to maintain an audit trail and quickly identify unauthorized or erroneous changes.
Key Features:
  • Automated login and configuration backup for routers, switches, and firewalls
  • Version control integration (CVS, Subversion, Git) for change tracking
  • Email notifications with diffs for any configuration changes
  • Support for a wide range of network hardware vendors (Cisco, Juniper, HP, etc.)
Use Cases:
  • Auditing network configuration changes for security and compliance
  • Quickly restoring device configurations after a failure
  • Collaborative network management by tracking changes in version control
Alternatives:
  • Oxidized – Modern alternative written in Ruby; offers a web UI and supports more devices out of the box
  • Unimus – Commercial alternative with a GUI, backup scheduling, and mass configuration deployment
