220221 - Attempt to access this FTP site frequently times out; if Mozilla reaches the site the display is incomplete.

Status: RESOLVED DUPLICATE of bug 178210

(Core Graveyard :: Networking: FTP, defect)

Description

[James J. Weinkam]

User-Agent:       Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.4) Gecko/20030624

When I attempt to access this IBM FTP site, Mozilla's behavior varies.  About
20-30% of the time the operation times out.  When this happens, upon dismissing
the timeout message, an empty FTP directory appears.  Even when the operation
does not time out the directory list is sometimes empty even though there are
actually files in the directory.  When the directory comes up empty, usually
clicking on up to higher directory displays the parent (fromibm) directory, but
sometimes this also results in an empty display.  When the parent directory
displays, clicking on os2 usually displays the os2 directory.  Once the
directory has been displayed, the files in it can be downloaded without problems.

When Netscape 4.6.1 is used to access this site, the "header" section of the
directory listing contains a couple of reminders to read the README files. 
These messages are not displayed when Mozilla is used to access the site.  While
the failure to display these messages is only a minor problem in and of itself,
it appears that it is the presence of these messages that cause Moailla to get
into difficulties.  iptrace reveals that the messages are being received but are
not being correctly recognized and displayed.

Reproducible: Always

Steps to Reproduce:
1. Enter the URL: ftp://testcase.boulder.ibm.com/ps/fromibm/os2/
2.
3.

Actual Results:  
Sometimes times out, sometimes displays empty directory, sometimes displays
complete file list but no "header" information.

Expected Results:  
This was copied from Netscape 4.6.1 using the clipboard.  The lines with an
asterix in position 1 are the ones that are not present in the Mozilla display.


Current directory is /ps/fromibm/os2

Confirming new.  I see this too in 20030924 PC/WinXP.  OS->All

Best I could get was an empty directory and a dialog box with the error "425
Can't open data connection"

Was able to get right in using Opera 7.2.

I too noticed this bug (see my note
http://forums.mozillazine.org/viewtopic.php?t=25838 for more info) some time
after the 20030911 win32 build.  

Fortunately, FTP connections seem to be working fine again in the 20031007 win32
build!  (However, FTP was not working as recently as the 20031004 win32 build,
the last available win32 build before 20031007.)

Is this materially distinguishable from bug 178210? I think most if not all IBM
ftp servers are set up the same.

Does the bug 210125 fix need to go on the 1.4.x branch? Maybe these two are
obsolete since that fix?
