Bug Description

Binary package hint: cups

Hello,

When I was remotely rejecting jobs, cups asked for "upgrade" (encrypted connection). No problem at all but the page it gave me was:

426 Upgrade Required

Você deve acessar esta página usando a URL https://2001:1291:xx:xx:xx:xx:xx:631/printers/deskjet-3420.

Howver, IPv6 URL should be:

https://[2001:1291:xx:xx:xx:xx:xx]:631/printers/deskjet-3420.

The latter worked.

Description of problem:

CUPS in a dual-stack environment insists upon some the use of an IPv6 address.

Version-Release number of selected component (if applicable):

$ rpm -q cups
cups-1.3.11-4.fc10.i386

How reproducible:

deterministic

Steps to Reproduce:
1. The printer stops for long enoug ... it is declared "stopped"
2. This is annoying and difficult to explain to civilians
3. An IT supervisor goes to http://printers.example.com:631 and presses "restart"
4. The CUPS service requires a redirect to an IPv6 address but uses an incorrect syntax

Actual results:

CUPS responds with

426 Upgrade Required

You must access this page using the URL https://2001:55c:4c15:7096:a00:46ff:fe16:bdb4:631/admin/?op=start-printer&printer_name=HP-Deskjet-960c.

Expected results:

The printer always works

Failing that

The correct URL syntax is:

https://[2001:55c:4c15:7096:a00:46ff:fe16:bdb4]:631/admin/?op=start-printer&printer_name=HP-Deskjet-960c.

With square brackets aroundt he IPv6 address

Additional info:

Client is Fedora 13 with Firefox 3.6.13
Server is Fedora 10 with cups 1.3

The LAN is dual stacked.
IPv4 to broadcast the printer availabilities; IPv6 "can't do broadcast" (sic)
IPv6 to transfer printer payloads.

This bug was fixed in the package cups - 1.4.6-4

---------------
cups (1.4.6-4) unstable; urgency=low

  * debian/patches/fix-broken-ipv6-uris.dpatch: When accessing the web
    interface via http: (unencrypted) and one does an adminstrative task
    which requires encryption, on upgrading to https: (encrypted) mode
    IPv6 IP addresses without "[...]" get inserted into the URL and the
    browser cannot parse the URL correctly. Fixed with a patch from upstream
    (LP: #744674).
  * debian/rules: Convert cups.png (CUPS logo for test page) to RGBA, as the
    original 8-bit-per-pixel color map format leads to a crash in libpng. This
    prevents the CUPS test page and the banner pages from printing
    (LP: #710881).
  * debian/control: Add ImageMagick to the build dependencies, as it is
    needed for the CUPS logo image conversion.
