longDescription = ''
UCARP allows a couple of hosts to share common virtual IP addresses in
order to provide automatic failover. It is a portable userland
implementation of the secure and patent-free Common Address Redundancy
Protocol (CARP, OpenBSD's alternative to the patents-bloated VRRP).
Warning: This package has not received any upstream updates for a long
time and can be considered as unmaintained.
