FILES

wackamole.conf

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."
