Package: cups Version: 1.3.10-1 Severity: important The CUPS server is rejecting all connections. With debug logging output, I see this every second:
=====
D [23/May/2009:09:48:12 +1000] cupsdAcceptClient: 9 from 192.168.5.7:631 (IPv4)
D [23/May/2009:09:48:12 +1000] cupsdReadClient: 9 POST / HTTP/1.1
D [23/May/2009:09:48:12 +1000] cupsdAuthorize: No authentication data provided.
W [23/May/2009:09:48:12 +1000] Request from "192.168.5.7" using invalid Host:
field "printserver"
D [23/May/2009:09:48:12 +1000] cupsdSendError: 9 code=400 (Bad Request)
D [23/May/2009:09:48:12 +1000] cupsdCloseClient: 9
=====
The host name ‘printserver’ is not invalid. It resolves correctly to
the machine running the CUPS server:
=====
$ host printserver
printserver.local.whitetree.org has address 192.168.5.7
=====
The server is configured in ‘/etc/cups/cupsd.conf’ to listen on that
address:
=====
Listen printserver:631
=====
Even if I set a client to use the FQDN, the same error occurs:
=====
D [23/May/2009:09:51:38 +1000] cupsdAcceptClient: 9 from 192.168.5.7:631 (IPv4)
D [23/May/2009:09:51:38 +1000] cupsdReadClient: 9 POST / HTTP/1.1
D [23/May/2009:09:51:38 +1000] cupsdAuthorize: No authentication data provided.
W [23/May/2009:09:51:38 +1000] Request from "192.168.5.7" using invalid Host:
field "printserver.local.whitetree.org"
D [23/May/2009:09:51:38 +1000] cupsdSendError: 9 code=400 (Bad Request)
D [23/May/2009:09:51:38 +1000] cupsdCloseClient: 9
=====
Could this be related to the following entry in the Debian changelog:
=====
* New upstream security/bug fix release:
- The scheduler now protects against DNS rebinding attacks. Please note
that this could lead to some regressions. (CVE-2009-0164)
=====
I'm completely unable to print or manage CUPS while this continues.
That sounds like a regression to me, but there's no hint of how to fix
it or know whether that's behind the problem.
