Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
Diald manages network links, particularly on-demand links such as dial-up SLIP or PPP. It can also be used to manage and/or monitor any network interface. Diald monitors traffic on the link and makes intelligent (and highly configurable) decisions as to when the link should be brought up or taken down. The included control program, dctrl, runs on any system with Tcl/Tk (yes, even Windows) and allows diald to be controlled and monitored remotely.
