CVSup is a software package for transferring and updating collections of files across a network. It consists of a server called cvsupd and a client called cvsup. CVSup is faster (often by an order of magnitude) and more flexible than traditional network packages such as rdist and sup. In addition, CVSup has special knowledge of RCS files (as used by CVS). Software projects using CVSup to distribute their CVS repositories include FreeBSD, KDE, and (shortly) Postgres.
cvsweb is a visual (WWW) interface for exploring a CVS repository. Its enhancements include recognition and display of popular MIME-types, visual, color-coded, side-by-side diffs of changes, and the ability sort the file display and to hide old files from view. cvsweb requires the server to have CVS and a CVS repository worth exploring.
The Cyrus SASL library is a generic library for easy integration of secure network authentication to any client or server application. It supports authentication via standard plaintext methods as well as CRAM-MD5 and DIGEST-MD5 shared secret methods and KERBEROS_V4 and GSSAPI Kerberos methods. The SASL protocol framework is used by SMTP, IMAP, ACAP, LDAP, and other standard protocols.
Dante is a free implementation of the proxy protocols SOCKS version 4 and SOCKS version 5 (RFC 1928). It can be used as a firewall between networks, controlling outgoing traffic. The package consists of two parts: a socks server and a proxy client that supports socks, HTTP proxies, and UPnP. RFC 1961 (GSSAPI) is supported in both the client and the server. Commercial support is available.
DBIx::Password provides an abstraction layer for password maintenance. It is database independent and only overrides the connect method (so it basically behaves as DBI normally does). You provide a single virtual user name in the connect method and the module determines which database/which user/which password to provide.
Deadman's Redirect is designed to replace whatever is loaded when you click on the Home button in your browser. It is a Web surfer's power tool that can be completely customized, using HTML, to fit the needs of the user. It allows for URL redirection as well as an interface to various search engines through its aliasing system. It also supports user-set aliases with functional arguments, RSS headlines, and a history of all the URLs that pass through it.
Depot is a software management tool providing a simple, yet flexible, mechanism for maintaining third party and locally developed software in large heterogeneous computing environments. Depot integrates separately maintained software packages, known as collections, into a common directory hierarchy consisting of a union of all the collections. This common directory is defined as the software environment. A set of configuration options manages interactions and intersections between collections in the environment. Depot facilitates the introduction, update, and removal of collections in a software environment. Custom environments and complete test environments can be easily created for individual machines or for sets of machines. Collections with unexpected problems can be replaced with previous versions or simply removed. Individual collections or files can be moved from remote filesystems to the local disks of workstations without the worry that the files may become stale. All this is achieved with minimal wasted disk space and administrative overhead.
