89947 - cannot administer Telocity ADSL modem

Status: VERIFIED DUPLICATE of bug 83465

(Core :: Networking, defect)

Description

[mjw]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2) Gecko/20010628
BuildID:    2001062823

I have Telocity (now DirecTV) ADSL service.  Telocity uses a custom ADSL Modem
that has a web interface for diagnostic purposes.  I have verified that both
Internet Explorer and Netscape 4.77 are working fine with this we interface, but
Mozilla 9.2 has problems.  Rather than display the a page, I get a dialog box
titled "Downloading null" that states:

You have chosen to download a file of type: "#1" [#2] from #3
What should Mozilla do with this file?

I am not sure if it matters any, but I am trying to get the page through a
Linksys BEFSR41 firewall.  This has never caused any problems before, though.

Reproducible: Always
Steps to Reproduce:
1.  Purchase Telocity ADSL
2.  Wait until they send you the modem
3.  Try to get a web page from the modem

What format is this trace?

Comment 4

[mjw]

It is in tcpdump format.  I used ethereal (http://www.ethereal.com/) to capture
the trace.

Comment 5

What URL do you normally go to to configure the modem?

Comment 6

[mjw]

The URL I use is

http://10.5.1.2/

but I'm not sure if that will work for everyone behind one of these
modems or not.

There are only 2 other URLs I know of on the box:

http://10.5.1.2/statistics
http://10.5.1.2/advanceddiagnostics

BTW, all the configuration information is sent from Telocity.  These
URLs are just for diagnostics, so it shouldn't be a show stopper for
anyone.

Could you run

wget -s -O testfile http://10.5.1.2/

and attach "testfile" to this bug as plaintext?  That file should contain the
entire response (including headers) from the server.

If you don't have wget, try this:

telnet 10.5.1.2 80

and type the following:
-----------------------
GET / HTTP/1.0

-----------------------
(leaving out the lines of "-").  Note the blank line after the GET.

Then you can copy/paste the server response to this file and attach it to this
bug....

Attachment: output of wget -s -O testfile http://10.5.1.2/

Comment 9

[Boris Zbarsky [:bzbarsky]]

OK.  The problem is the blank content-type header.  Thanks for that file!

Looks like a duplicate of bug 83465 ("response with empty content-type opens
helper dialog").  That one is also reported against a Telocity DSL router.
