Empty List when using FTP [message #29191]

I just got a hold of Eclipse RSE, and I am attempting to use it to connect
to my remote webhost using FTP. However, using the default settings, while
it does connect properly, and appears to change to the correct folder
(watching the console text, I see it move to /silverso which is my home
directory), the Home list is -always- empty. This happens whether it is an
active or a passive connection. I know there are files and folders in
there. Anyone have any ideas what I can do to see my files and folders?

Hi Katie,

this sounds like a list parsing exception. Please open a bugzilla
bug for the issue:
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Target%2 0Management

You can try the following:
1.) Check the error log. Any exceptions there?
Window > Show View > Error Log
or
Help > About > Configuration Details >

2.) Create a subfolder of your home, which only holds 1 file.
In RSE, after connecting FTP, create a filter for that
subfolder:
Right-click > New > Filter : folder=/silverso/subFolder
can you see the contents of subfolder?

3.) Attach contents of the FTP Logging Console.

4.) Connect your FTP server with some commandline FTP client,
and attach output on the bug:
ftp yourhost
ftp> dir

Cheers,

PS when your homedir contains a file that was changed
on 29 Feb 2008, the issue could be
https://bugs.eclipse.org/bugs/show_bug.cgi?id=220939

which we should be able to fix reasonably soon by moving
to the newly released Commons Net 2.0

Hi,

I've just installed RSE and have been trying to make an FTP connection
to a target platform running uClinux.

I get the same problem - FTP connects but I can't see remote
files/folders. If I create a file I can use Linux cmd line ftp or
telnet to the target to see that the file has been created but it still
doesn't appear in the Eclipse view.

I took a Wireshark trace and can see the FTP-DATA packets containing the
file listing being returned but nothing appears in the Eclipse view.
FileZilla and Firefox have the same problem (they connect but don't list
files). But cmd line ftp works so I'm sure TM could be made to work. I
suspect the date/time parsing as our target currently always returns 0,
e.g.:

root:/> ls -la
drwxr-xr-x 15 0 0 0 .
drwxr-xr-x 15 0 0 0 ..
drwxrwxr-x 2 0 0 0 bin

Is there anyway to relax the parsing through configuration or do I need
to look at creating a new parser? If the latter, how would I go about
debugging this in the plug-in? Can someone point at the general area in
the code that deals with LIST parsing?

Cheers,

Jon

Hi Jon,

I think you should be able to configure the date format just by editing
plugin.xml -- you can do this by self-hosting to debug it, i.e. you
modify the UNIX ftp listing parser extension; if it works you can just
copy that extension into your own plugin (with a different name), and
that way you can ship an extension to RSE to make your uCLinux targets work.

Self-hosting, see
http://wiki.eclipse.org/TM_and_RSE_FAQ#Working_on_TM_.2F_RSE
* File > Import > Plug-In Development > Plug-ins and fragments
- org.eclipse.rse.subsystems.files.ftp
- import with source folders

Edit plugin.xml of that plugin, enter a proper recentDateFormatStr
into the "UNIX" listingParser extension, see
http://dsdp.eclipse.org/help/latest/topic/org.eclipse.rse.do c.isv/reference/extension-points/org_eclipse_rse_subsystems_ files_ftp_ftpListingParsers.html

* Run > Run Configurations > New "Eclipse Application" Launch, Run

test and see if it works

If it works, in order to bind "Your" listing parser against your
target by autodetection, check and see what the "SYST" command
returns on your target. Put a regular expression matching that
String into your listingParser extension.

Cheers,

Hello,

I've the same problem with LIST command in FTP connection.
FTP don't list the directors and files in the LIST command request in
a uClinux target.

When I use a Standart Linux FTP Client the LIST command work:
ftp> ls
200 PORT command sucessful.
150 Opening ASCII mode data connection for '/bin/ls'.
bin dev drivers etc home lib mnt proc
sbin sys tmp usr var
226 Transfer complete.

When I use Eclipse RSE FTP Client the LIST command doesn't work:
LIST -a
150 Opening BINARY mode data connection for '/bin/ls'.

226 Transfer complete.

A dump observation:
- FTP Client LIST response is in ASCII mode, and in RSE is in BINARY mode.

Pheraps everyone already noted it, but I'd like reforce it.

Tks

I've since written an Eclipse plugin that uses the Apache Commons FTP
library and I had to write my own parser to get it to work with uClinux.

If you want to get your hands dirty you'll need to create a class that
implements FTPFileEntryParserFactory and returns object(s) that
implement FTPFileEntryParser.

You can then construct an FTPClient with your new class:

FTPClient ftp = new FTPClient();
ftp.setParserFactory(new MyFtpEntryParserFactory());

Hope this helps you or anyone else with the same issue!

Cheers,

Jon
