Try the CVS version (available for download). And also, it supports
only Solaris 8 and up. So, if you are using Solaris 2.6 or 7 you will
have all sorts of problems.

Alex,

I had the same problem, basically wackamole won't work without a
range of IP addresses given in the of statement. To make this a
single IP address set of to:
of a.b.c.1-1

This solved the problem for me when I was testing.

The CVS version doesn't suffer from that shortcoming. We are working
out the details of rolling the current CVS version into a formal
release. There are many details remaining and I personally haven't had
the opportunity to test it on anything but FreeBSD.

The CVS version allows almost everything on the wishlist from earlier.
This particular feature would be specifying IP addresses and interface
it is suppsed to be "plumbed" in a completely non-contiguous range.
This is required for doing router or transparent bridge failover (which
is what we are doing with FreeBSD and wackamole).

I have two FreeBSD boxes running wackamole sitting on a 100Mbs uplink.
The failover is "subsecond" if I just yank the powercord on one of the
machines.

Sounds cool, I'll definitley keep an eye open for when the new version
gets released. Haven't had much of a chance lately to play around
with it due to this pesky work commitments thing. :-)

Keep up the good work.

Andrew,

That's a cool trick. :) Do you have to "plumb" the interfaces before
wackamole start assigning address to it? Someone told me I don't have to.
But if I don't, no address get assigned.

Thanks!

Alex

Alex,

To be honest I can't remember whether or not I had to plumb the
interfaces, (the security admin has stolen my test box because
it had a quad fast ethernet card :-( )

I know that I did plumb the interfaces, but that was before I
found the need to set OF correctly (thus they were already plumbed
when I started).

Oooh. Would you care to go into a little more detail about how this
works?

Cheers,
