lbcd is a daemon that answers UDP packet requests and returns a packet of information about basic system information, including uptime, load average, number of logged-in users, whether someone is on console, and free space in /tmp. It can also check the availability of particular services. It is intended for use with a simple software load balancing system such as lbnamed.
Also included in the lbcd package is a simple client program to query an lbcd server and display a formatted version of the results.
lbcd was originally written by Roland Schemers and was largely rewritten by Larry Schwimmer to add support for protocol version three and checking availability of local services. I currently maintain this package for Stanford.
lbcd is written in C, so you'll need a C compiler. It also uses kernel calls to obtain load and uptime information, and at present has only been ported to Linux, Solaris, generic BSD, AIX, HP-UX, IRIX, Digital Unix, NeXTSTEP, SunOS, and ULTRIX. Platforms not listed (such as Mac OS X) may require some porting effort, as may old or unusual platforms that aren't regularly tested.
lbcdclient is written in Perl and requires at least version 5.004.
If you plan to hack on the lbcd sources, you'll also need Autoconf 2.57 or later if you want to change the configure scripts.
