NAME

       wackamole - IP-failover high-availability tool


SYNOPSIS

       wackamole [-v] [-c config_file ] [ -s spread ] [-u user ] [ -d ]


DESCRIPTION

       wackamole runs the Wackamole IP-failover HA tool using the
       wackamole.conf file as a base configuration.


OPTIONS

       -v     Display version information and exit.

       -d     Turn on debugging and do not daemonize.

       -u user
              Instruct wackamole to use user instread of Wack<pid> as it's
              username when connecting to Spread.

       -s spread_loc
              Connect to Spread running at spread_loc

       -c config-file
              Use an alternate configuration file config-file instead of
              wackamole.conf.


FILES

       wackamole.conf
              The default config file location is dependant on the install
              prefix.  ./wackamole.conf is also searched if a local file is
              not found.


DIAGNOSTICS

       By default, Wackamole will log any errors to syslog.  Check the
       appropriate log desitnation on your platform.


BUGS

       Linux  Wackamole makes extensive use of ioctl()s on network devices.
              When dropping and interface such as eth0:4, all subsequent
              interfaces (eth0:5, etc.) will disappear and no longer function.
              There has been special code added that causes Wackamole on Linux
              to iterate through all IP addresses after a balancing round and
              attempt to re-plumb them.  This may cause gratuitous entries to
              syslog as well as extra unsolicited ARP responses.

       Solaris
              Solaris' local arp-cache is, as far as the author is aware,
              completely undocumented.  The code in Wackamole to open /dev/ip
              and attempt to read the ARP cache was written only by looking at
              the output of truss arp -an and should be considered a "stab in
              the dark."
