chrony is a client and server for the Network Time Protocol (NTP). This program keeps your computer's clock accurate. It was specially designed to support systems with intermittent Internet connections, but it also works well in permanently connected environments. It can also use hardware reference clocks, the system real-time clock, or manual input as time references.
The Cistron Radius server is mostly compatible with Livingston's 'radiusd-2.1', except without the s/key or menu support. It has additional features such as multiple DEFAULT entries with fall-through, a session database (who is online), the ability to limit connections on a per-user basis, and much more.
ClusterNFS is a set of patches for the "Universal NFS Daemon" (UNFSD) to allow multiple clients to nfs mount the same root filesystem by providing "tagged" filenames. When a client requests the file "/path/filename", the ClusterNFS server checks for the existence of files of the form "/path/filename$$TAG=value$$". If such a file exists and the client has a matching value for KEY, this file is returned. If the client does not have a matching value or no such file exists, the file request proceeds as normal. Currently supported keys include HOST (hostname), IP (IP number), CLIENT (matches any nfs client) and CREATE (for "tagged" creation of files).
command history is a quick and dirty script created to show what commands were executed on the day command history is run. Its purpose is to help sysadmins conveniently keep a watchful eye over their users to make sure they aren't snooping around too much, and is best run from crontab to produce mail output each day.
Conserver provides remote access to serial port consoles and logs all data to a central host. Local and network serial connections are supported. Server console history can be replayed from the console app even if the server is down, and multiple users can connect to a single serial connection.
