FTP Plugin connection problem

[yeellow]

Hi,

I have troubles connecting to my ftp server. I use smallftpd (http://smallftpd.sourceforge.net/) and it works fine when I connect using PC version of TC or when I use Ghost Commander on Android.

When I try to connect from Android TC I get the message that the folder is being read and than nothing happens. I have to manually cancel it. I tried many different options (passive/active, etc.) but with no success. Here is the log (some comments are still in Polish, I translated important ones):

Hmm, no idea - I will try to install the server and make a connection.

Hi,
I have faced quite similar issue with FTP connection.
I am trying to connect to my own ftp server which is placed behind the router's NAT (appropriate port forwarding rules are configured) using the "PASSIVE" mode. "Login" proceeds properly but connection fails after the remote server sends the "PASV" command with local IP:
====
2012-09-21 10:09:13 FTP:227 Entering Passive Mode (192,168,0,3,80,193).
2012-09-21 10:09:16 FTP:QUIT
2012-09-21 10:09:16 FTP:221 Goodbye.
====
I have tested the same scenario using the desktop version of TC and found that such behaviour is handled correctly:
====
PASV
227 Entering Passive Mode (192,168,0,3,80,183).
Server reports local IP -> Redirect to: 94.178.5.226
LIST
====
The old beta versions of Android TC worked properly the issue appeared after the update to 1.0.3.

I am looking forward your advise.

PS. Just for case I have attached the full logs from AndroidTC and DesktopTC:

TC for Android does not handle FTP by itself, it's handled in a plugin. I need to know which plugin version is the last one which works. Btw, currently there isn't even a beta version of the FTP plugin, it's still the same as the one for TC 1 for Android.

Here are the last FTP plugin versions:

Latest version 1.01:
https://plugins.ghisler.com/aplg/tcandroidftp101.apk

Previous versions: Overview see:

Oh. Count me in on this one! I think I have the same problem with Shuttersnitch on iPhone: http://www.ghisler.ch/board/viewtopic.php?t=35685

The problem is that the server reports its internal address instead of the true internet address:
227 Entering Passive Mode (192,168,0,3,80,193).

Instead of: 94.178.5.226

TC for Windows contains code to detect this and work around it. FTP for Android is much simpler and doesn't contain these workarounds (there are many).

Will the FTP plugin workaround be implemented for Android?

Sorry, I meant to reply to the related topic with number 35071. I can't post the URL due to spamming restrictions.

Forget everything I have said. I managed to get the FTP server settings altered to work with Total Commander, which is great, because I didn't want to have to use a different file manager, especially a single-pane one, after 18 months with Total Commander.

For future reference for other users, the problem was with the FTP server, GuildFTPd. The "Custom IP" field in the "Passive Mode" section, in the "Advanced Settings" tab of the Admin options, was set to the local IP address (LAN) of the FTP server, instead of the external IP address (WAN) of the FTP server, which meant that Total Commander could not get a directory listing from the FTP server in passive mode, even though it had successfully logged in.

Sorry for such a misleading first post, but it was done under difficult circumstances using a mobile phone, and I also had to overcome some problems with registration.

Regards,
Jacko
