Description Ole Craig 2005-05-25 10:36:58 UTC

Possible upstream? 

Connecting to http://localhost:631/ with a browser should put me into the CUPS
web interface, but instead I see html source. This occurs because cupsd responds
to the HTTP GET with headers that include "content-type: text/plain" instead of
the expected "text/html". I've pasted an ethereal capture of the conversation.

This was functional the last time I added a printer, but I can't say for sure
what version of cups that was (I update pretty regularly; it was somewhere in
the vicinity of 2-3 weeks ago.)

Reproducible: Always
Steps to Reproduce:
1. emerge cups
2. firefox http://localhost:631/
3.

Actual Results:  
raw html source presented as ASCII

Expected Results:  
loaded the CUPS web interface as html

Comment 1 Ole Craig 2005-05-25 10:43:53 UTC

Created attachment 59803 [details]
packet captures in libpcap format

raw packet trace in libpcap format, for your tcpslicing pleasure.

Comment 2 Phil Richards 2005-05-27 09:36:28 UTC

Yep, same problem here.  Pages are being served as plain/text, causing mozilla,
firefox, epiphany and lynx to refuse to render them.

Web administration interface is now completely unusable.

Comment 3 Ole Craig 2005-05-27 09:57:24 UTC

NB: backing off to -r2 ("emerge =cups-1.1.23-r2") makes the problem go away.

Comment 4 John Youells 2005-05-28 17:52:58 UTC

Backing off to -r2 ("emerge =cups-1.1.23-r2") did NOT fix this problem for me.

Comment 5 Phil Richards 2005-05-29 01:06:19 UTC

Funnily enough, it did work for me.
But, looking at the difference in the ebuilds, I have no idea why it should...

I've just tried r3 again and it appears to be working for me now.
Has the ebuild been changed since the last time, I wonder?
(No way of checking here.)

Comment 6 Carl A. Dunham 2005-05-29 08:29:44 UTC

It looks like something zapped /etc/cups/mime.types -- re-emerging brings it back.

Comment 7 Heinrich Wendel (RETIRED) gentoo-dev

2005-05-31 15:41:34 UTC

remerge cups, works here then

Comment 8 Max 2005-06-05 07:24:05 UTC

Remerging doesn't help me. Problem is still the same, even after deleting
/etc/cups and remerging.
