Nevermind Who a.k.a nwho is a GUI for the linux/unix utility rwho. Its interface based on GTK displays who is logged on to machine in your local network depending on how you configure rwho and rwhod. Its main feature is the ability to have a picture in XPM format for each login that is displayed when you click on the login. It is designed for sysadmins to visually verify at a glance that people logged in on machines are really who they pretend to be.
hc-cron is a cron daemon for 'home computers'. It runs specified jobs at periodic intervals and will remember the time when it was shut down and catch up jobs that have occurred during down time when it is started again. Hc-cron is based on the widely used vixie-cron and uses the same crontab format so that it can be used as a drop-in replacement for that program.
Req is a tracking system. People with problems or questions send requests via email to a group responsible for dealing with those issues. Those requests are assigned numbers that can be tracked and managed in various ways. The group handling the requests needs to have access to a UNIX computer or network.
Spong is a simple system-monitoring package. It features client-based monitoring (CPU, disk, processes, logs, etc.), monitoring of network services, grouping of hosts (routers, servers, workstations, and PCs), host-specific contact and downtime information, configuration on a client-by-client basis, results displayed via the Web, history of problems, messaging (via email or pager) when problems occur, and verbose information to help diagnosis problems. It communicates via simple TCP-based messages, and is written in Perl.
Vcron is a graphical interface to cron and at, allowing to view, modify, delete and add programmed actions. You will no longer have to cope with the cron/at horrible syntax. Vcron is written in tcl/tk , it is a very easy to use multilingual application, with an inline manual. It has been tested on RedHat and Slackware, but it should work without problems on other platforms.
The netpipes package makes TCP/IP streams usable in shell scripts. It can also simplify client/server code by allowing the programmer to skip all the tedious programming bits related to sockets and concentrate on writing a filter/service. <P>Applications of these utilities can include file transfer, network backups, HTTP queries, remote procedure calls, and TCP daemon testing. <P>The SSL encryption filter available in the US/Canada version can be applied by shell scripts communicating with secure HTTPDs and can be used to make an SSL IMAPD out of a non-SSL one. (requires the SSLeay library).
