[Grok-dev] Problem with Tutorial / 'Sample' Project

[grok at richardshea.fastmail.fm]

Hi - I've been following the tutorial. I have done ...

$ grokproject Sample
$ cd Sample
$ bin/paster serve parts/etc/deploy.ini

... and sure enough I can login when I access http://localhost:8080 on
the same machine. However when I try to access http://myhostname:8080 I
don't get the web page.

I realise this looks like a firewall problem except that on the same
host I also have a Zope installation which serves on 8080 and if I start
that and attempt to access http://myhostname:8080 I get served the
pages.

Is there something about the default setup of Grok projects that it will
only serve pages locally until you do something to it ?

thanks

Richard.
