OK, that's weird. When I run it, I get this (expected) behaviour:

I'm assuming you're running linux. For reference, I'm running Ubuntu
10.04.1 LTS. Some relevant local output: (with some IPs changed to
protect the innocent :-)

I'm not sure. When I'm not sure I revert to columbo style questions -
I don't suppose you're running a firewall (eg via iptables or
ipchains) or not running networking?
It wouldn't surprise me for that to be the "obvious" problem...
> PS: Also, what is the path to the svn trunk?
In order to checkout a read only version of the kamaelia trunk you
grab this:
svn co http://kamaelia.googlecode.com/svn/trunk/ kamaelia-trunk
(BTW, I'm near connectivity again - as may be obvious - so I'll reply
to the other mails shortly!)
If you'd like a scratch space in /trunk/Sketches/<initials> just let
me know.
Regards,
Michael
