The Collaborative Virtual Workspace (CVW) provides a "virtual building" environment where teams can communicate, collaborate, and share information regardless of their geographic location. CVW takes virtual meetings one step further and enables virtual co-location through persistent virtual rooms, each incorporating people, information, and tools appropriate to a task, operation, or service. The software optionally makes use of multicast tools to provide audio and video.
mailq_applet is a GNOME 1 panel applet that shows the status of your outgoing mail queue. It's intended for dialup users who may connect, wait for the queue to drain, then disconnect. Having this on your panel is much more convenient than running mailq over and over again from a terminal. It works with Exim and Sendmail. If you use a different MTA, you may need to make some changes, but the code is so trivial that that shouldn't be difficult. This code is no longer used or maintained by its author.
ncp can copy files between networked computers and accounts without hassles (nor features like compression and encryption), and you do not even have to name the target machine if it is in the same LAN. npush and npoll can copy files (and pipe data) between machines without having the specify or even know the machine name in advance.
The Simple Sockets Library makes sockets easy to use and comes as public domain source code. It resembles C's file I/O, uses whatever port is available, has named servers and port reuse, streaming/blocking sockets used, polling support, blocking/selection support via numerous functions, timeout control and firewall support.
SmartSign is a set of modules which allow integration of smartcard technology into an OpenCA based Public Key Infrastructure in order to provide smartcard-based digital signature and local authentication security services. It allows direct signing of e-mail and e-news from within Netscape using smartcards and supports signing of generic files from command line. The package includes a PAM module too, which allows system administrators to integrate smartcard-based authentication for local users. A modified version of the OpenSSH client allows secure authentication to a remote server. A couple of command line tools allow signing and verifying generic files from the shell. Finally, a command line interactive shell supports all operations on the card, and can be used to write scripts that automate particular tasks on the card. Currently only Schlumberger Cyberflex Access 16K is supported.
tkbiff allows arbitrary commands to be executed upon mail reception. If you like programs such as xbiff and xbiff++ but wish they were more flexible, then you'll like tkbiff. Unlike other biffs, tkbiff is fully customizable. tkbiff also doesn't waste your valuable screen space with icons; instead, it shows you the mail itself. It supports UNIX, Mac, and Windows, IMAP, POP, and UNIX-style mail files, and SSL and APOP.
