Not really, I'm afraid. We all know a hubbed_hosts file works. Mark Fletcher has written extensively about it and I have said a thing or too also. What I want to know is why following the advice from Liam O'Toole doesn't work for me, even though I have followed the instructions exactly. BTW: It would be 'desktop: 192.168.7.20' and 'desktop.monet:192.168.7.20' in hubbed_hosts. -- Brian.
