Browser asks where to save bb-hostsvc.sh

Using the format
In bb-hosts:

0.0.0.0	HOSTNAME (without domain)	# ssh

the browser asks where to save bb-hostsvc.sh

Link-address: .../hobbit-cgi/bb-hostsvc.sh?HOST=hobbitzone&SERVICE=info
Alt-text of the link is: info:green:0.0.0.0

I've already compared with another hobbit-server's configuration, but found no differences.

The mailing-list archive did not help (perhaps wrong search term?!).

When entering the IP-address instead of 0.0.0.0 (in bb-hosts) it works fine...

Any ideas?

Thanks in advance,
Michael [hobbit-newbie!!]
