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