How do you mean? If I downloaded DMC-0.8.2.jar and executed it on a WIN
client, how would I know about "it should be installed by DRBD MC, whatever
OS you are using". I don't see anything at http://oss.linbit.com/drbd-mc/
or http://www.drbd.org/mc/management-console/ that gives cluster host
requirements for DMC-0.8.2.jar.
It was only after I ran DMC-0.8.2.jar that I realized it was looking
for /usr/local/bin/drbd-gui-helper-0.8.2 on the cluster hosts. So it
seeemed logical I should download drbd-mc-0.8.2.tar.gz to see if it
contained drbd-gui-helper. So I copied drbd-gui-helper to /usr/local/bin
and created the /usr/local/bin/drbd-gui-helper-0.8.2 symlink pointing
to it (after having a look to what it does).
As I'm just sort of 'kicking the tires', I was only installing the
minimum needed to have a look.

Yes, in fact it did continue, but it was awkward - I thought "why does
it need DNS, I gave an IP address?"

I will try again now that you have reassured us. Thanks :)
