FirstWave opConfig vs RANCID

FirstWave opConfig has no write-up on Specifiction yet; its figures are above.

RANCID is free, open-source software that monitors network-device configurations and keeps their changes in revision control. It logs into devices, runs commands, reformats output to remove changing values that do not represent meaningful configuration differences, emails detected changes, and commits updates to version control. CVS, Subversion, and Git are listed for maintaining history. Login scripts connect through Telnet or SSH, and included looking-glass software provides device access. The maker lists support for equipment including Allied Telesis, Cisco, Juniper, Catalyst, Foundry/Brocade, Redback, ADC, Alteon, and HP Procurve, among others. RANCID is available for Linux, macOS, and self-hosted deployment; version 3.14 is identified as current. It has no GUI or web interface for configuration, although separate tools can show diffs and repositories. Setup guidance generally assumes basic Unix and tool knowledge, and versions 2.3 onward require Expect 5.40 or later.
