Package: cups
Version: 1.4.4-7
Severity: normal
I have used qemu/kvm for some years to run a winxp guest. The guest used
http://10.0.2.2:631/printers/PRINTERNAME
to access my cups printer. However, after upgrading to squeeze, this doesnt
work anymore. The printer is not accesible (from the guest. On the host
everything is ok) and I find the following message in /var/log/cups/error_log:
E [03/Mar/2011:18:13:19 +0100] Request from "localhost" using invalid Host: field "10.0.2.2:631"
Looking in the cups code (/scheduler/client.c) I found that cups will only allow requests, if
the ip is 127.0.0.1 or for localhost.
Adding the line
ServerAlias *
and/or
HostNameLookups on
did not help. The problem has been described by different people:

http://forums.virtualbox.org/viewtopic.php?f=7&t=33473
it may also be connected to debian bug #530027
However, I did not find a suitable solution yet. (other than using samba
or a bridge for the network connection)
As this has worked before I think it is a bug.
Regards,
Juergen
