Lbcd is a daemon that answers UDP queries for system load information and returns such information as uptime, load, number of logged-in users, percentage free of /tmp and /var/tmp, and whether there is a user on the console. It is intended for use with a load balancing system, and is particularly useful for such things as UNIX clusters for remote login where a traditional hardware load balancing solution doesn't work as well.

No load balancing system is included in this package, only the client daemon and a simple Perl script to query it. No security or access control is done by the daemon, so access control must be done via iptables, a firewall, or an equivalent system.
