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.
wwan-helper is a script that establishes a UMTS connection using a Ericsson F3507g Mobile Broadband Module. It was designed to be used with a ThinkPad T420s. It takes care of resetting and reinitializing the modem if the hardware fails to get a WWAN connection, and retries as often as necessary until the UMTS connection is really established. It is meant to run as a hook script for the ifup / ifdown mechanism, but should also work on other networking systems.
