i have a cups server running on ubuntu 9.10 on my home network. right now i can access it at 192.168.1.101:631, but when i try to access it at myservername.local:631 i get a 400 Bad Request. here's the relevant section from my current cupsd.conf:

ServerName 192.168.1.101

# Only listen for connections from the local machine.
Listen localhost:631
Listen /var/run/cups/cups.sock

# any of the below 'Listen' directives all yield the same result
Listen 192.168.1.101:631
#Listen *:631
#Listen myservername.local:631

</Location>

i get the following in /var/log/cups/error_log:

E [03/Jan/2010:18:33:41 -0600] Request from "192.168.1.100" using invalid Host: field "myservername.local:631"

what do i need to do to be able to access the cups server at both 192.168.1.101:631 and myservername.local:631?
