Passive Mode FTP in MATLAB

These files allow users to use passive mode FTP in MATLAB.

Description

FTP clients working behind a firewall often use a passive mode FTP connection to the server to avoid issues with their firewall. MATLAB's ftp object does not have passive mode capability. The attached files modify this MATLAB class to allow for this functionality. These files simply use the Java methods available in the FTPClient Java class used by MATLAB.

See installation instructions in the README file.

Files/functionss added:
PASV(FTP)
ACTIVE(FTP)
dataMode(FTP)

Files modified:
@ftp/ftp.m
@ftp/private/connect.m

Update: December 29, 2010
- Updated install instructions allow this FTP class to work seamlessly with the MATLAB Compiler (original files will also work with Compiler if the new install instructions are followed).
- Improved the object to preserve connection mode (active/passive) if connection to host is lost and then reconnected.
- Updated files to use the R2010a version of FTP class.
- Tested with MATLAB R2010a and R2010b.

This is great! Just what I needed to get consistent FTPs thru our firewall. Nice installation directions.

Well written instructions. This is one of the best contributions I have found in over two years of using the Mathworks Exchange. Many thanks.

I struggled for three hours trying to get the MATHWORKS ftp routines to work. Had no luck. I finally suspected that the firewall(s) were getting in the way of making ftp work. I then searched and found Idin Motedayen's passive ftp routines. I downloaded his zip and in 10 minutes I was doing ftp up & downloads within my MATLAB program.

works great; solved the java IO stream error problem form me

[Moroni Noronha]

This is the fix I was looking for after 5 hours looking everywhere. Works for Windows XP!! Thank you very much for this product.

[Ray Goldsworthy]

Fantastic! Solved my ftp 500 errors when downloading directories. Thank you!

Great, but the code only seems to work when I run it on my computer with Matlab installed. When I compile the code and run it with MCRInstaller, I guess It uses the original ftp code. Any tips, I've tried to copy the ftp.m code and rename it. Then including the renamed file when I compile, but I cannot use the function class(h,'ftp'). My guess is that ftp.m must be located in .../@ftp/
or?

[Darren Aklestad]

Has anyone found a solution to using the passive mode in a compiled application via the MCRInstaller?

[Bryant Svedin]

Thank you so much. This totally solved my problem. Luckily it took me just over an hour of frustration and google searching to find this instead of 3, 5 or more.

this function works very well , i wonder why the original matlab files do not

Hi folks,
Thanks for downloading and rating this submission. For those trying to use this class with MATLAB Compiler, here's the fix:
1. Locate your @ftp folder and copy it to a location outside MATLAB toolbox directory.
2. Add the folder containing @ftp to the top of your MATLAB path.
3. Copy the provided connect.m into your new @ftp/private folder.
4. Copy the rest of the files to your new @ftp folder (ftp.m pasv.m, active.m, dataMode.m)
5. Restart MATLAB and rehash your toolbox cache by typing:
    rehash toolboxcache
6. You can now use passive mode FTP as before, and if you compile the application, it will work.

I have updated the submission and install instructions. The update should hit the File Exchange in a few days.

Just implemented on 2011a and everything appears to be working without problem. Thank you!

This is a really great contribution. I struggled with some ftp code that previously was working fine, but broke when the lab IT infrastructure was updated - presumably because of a firewall. A quick google search brought me here, and within five minutes I had these files downloaded, installed, and my old code working again. Thank you!

Solved my problem after spending a weekend restarting Matlab every time it got stuck during ftp downloads. Thanks.
