[Pkg-cups-devel] Bug#501090: CUPS cannot print to an IPv6 IPP/HTTP address

[Kyle Brantley]

Package: cups
Version: 1.3.8-1lenny1

If you configure an HTTP or IPP printer by IPv6 address, printing will 
fail with the error "client not found." Referencing the printer by DNS 
(AAAA record) works as expected.


The problem is actually pretty simple. Within the IPP request set from 
cups to the IPP server (also cups):

printer-uri at http://2001:470:d82b:-:217:31ff:fec4:919a:631/printers/HP1320

The problem is that the IPv6 address needs to be encapsulated within [] 
brackets. Example of what the request SHOULD be:

printer-uri at http://[2001:470:d82b:-:217:31ff:fec4:919a]:631/printers/HP1320

Testing against the same cups server via IPv6 address from Windows Vista 
gets me the following request:

printer-uri at http://[2001:470:d82b:-:217:31ff:fec4:919a]:631/printers/HP1320

Which works as expected, and the printer rolls off the test page. It 
should be noted that the actual communication from host to host works 
fine, but just that the IPP request is malformed.
