Here are the conf files, but when i try wackamole with the -d flag, it gives a segmentation fault, on both machines. without that flag, it works on one machine (who's physically on the same subnet with the vip subnet), but not on the machine that's on a different subnet. -----Original Message----- From: Ryan Caudy [mailto:[email protected]] Sent: Wednesday, April 02, 2003 10:09 AM To: [email protected] Subject: Re: [Wackamole-users] (no subject) I don't know of any flags to increase debugging output... afaik its an all-or-nothing thing. Please send your wackamole.conf files (or just one, if they're identical), your spread.conf file, and the output from wackamole run with -d. I'll take a look, and see if I can help. --Ryan John Jolet wrote: > I retried this, starting up just the second machine....all I get is a > message in syslog "no such interface". what is it talking about? i've got > an eth0, which is what i'm trying to assign the vip to.

All daemon-to-daemon UDP multicasts and # the tokens and any monitor messages must use the 192.168.0.4 interface. # The second host multihomed2 has a similar setup, except it also listens for # client connections on the localhost interface as well as the 1.2.3.5 interface. # If you make any use of the extra interface stanza ( a { } block ) then you must # explicitly configure ALL interfaces you want as Spread removes all defaults when # you use the explicit notation. # The third multihomed3 host uses a shorthand form of omitting the D or C option and # just listening for all types of traffic and events on both the 192.168.0 and 1.2.3 # networks. If no letter is listed before the interface address then ALL types of # events are handled on that interface.
