PMSVN is a server configuration management and monitoring tool. It helps keep track of administrative actions for many servers with many administrators. It allows administrators to put specific configuration files under revision control and eases the burden of having to remember to commit changes. It can synchronize and monitor the consistency of small bits of configuration that are the same or mostly the same across many servers.
Archivist is a network device configuration archiving and versioning program. It uses Subversion as its revision control system. Its multithreaded design makes it quite fast and thus suitable for operation on large networks with thousands of network devices. It supports Cisco IOS, Cisco CatOS, Juniper JUNOS, and Brocade/Foundry MLX series, but it can be easily extended to support any SSH or telnet-based network device by creating your own config download and post-processing scripts.
Bcfg2 helps system administrators produce a consistent, reproducible, and verifiable description of their environment, and offers visualization and reporting tools to aid in day-to-day administrative tasks. It is based on an operational model in which the specification can be used to validate and optionally change the state of clients, but in a feature unique to bcfg2 the client's response to the specification can also be used to assess the completeness of the specification. Using this feature, bcfg2 provides an objective measure of how good a job an administrator has done in specifying the configuration of client systems. Bcfg2 is therefore built to help administrators construct an accurate, comprehensive specification. Bcfg2 has been designed from the ground up to support gentle reconciliation between the specification and current client states. It is designed to gracefully cope with manual system modifications. Bcfg2 can also enable the construction of complex change management and deployment strategies.
