Secure FTP Action Plugin

[Canter]

That's what I get for cutting and pasting.
Sorry for the confusion - I was confused by the Success=0 but the not connected alert kept popping up.

So, looks good. Thanks again.

I'm having problems with the standard FTP plugin. The issue (a show stopper) is that I cannot reliably download large files, i.e. 1 gig to 5gig (only tested with 2.8gig file so far....)

Does your plugin have any issues with larger files in the gigabytes? If so, I could setup my FTP server with a secure connection. But there's not much point if it cannot handle 3,4 ,5 and up gig files.

FTP is relatively unreliable as it doesn't have a lot of built in packet-checks...

Can you reliably use ftp.exe to download these large files? if so, then it could be the plugin -- but I just did a 3 gig file (LAN) via the ftp plugin w/o issue...

Well, I don't really see much of an alternative. From what I understand, HTTP transfers are not as reliable, and are also slower. With smaller files i.e. 34mb the FTP plugin has been sterling. Its been downloading the files quickly and with a 100% success rate, and those both over a local test (from a windows PC to an FTP server running on a virtual linux box) and also over the internet.

The FTP server is a very well regarded one, and one with large file support. I've tested downloading the 2.8gig file from my Linux server using CuteFTP, and it seems to work fine. The server was giving me a bandwidth speed of 149mbits, and the downloaded .zip file was fine.

So, the problem does appear at this point to be with the FTP plugin. My guess is it simply cannot handle (correctly) files that are over 2gig (32bit file handles?).

Thanks upeters.

Can anyone confirm (or not) if this plugin can handle downloading large files i.e. 2gb+ , ideally 4gb+

?

I'll have to check. But as I still haven't managed to implement callbacks in this plugin, it probably isn't a good idea to use it in the current stage, as you won't have any idea how much of the data was already transferred. And I understood that you are able to transfer the huge files with the normal FTP plugin, just the callback function is showing a wrong amount, due to a variable overflow.

Hi, well, yes and no. One download off site, at a friends that was testing the manager for me did seem to download the file. He reported my manager had downloaded the 2.8gb file and had unzipped it correctly. However, he said the manager had then gone into a loop and was acting oddly (I've tested it with several 34mb files, like download 3 files in a batch, and it was fine). So it looks like the 2.8gb file freaked it out.....

However.. I've tested it locally earlier this evening. And it was problematical. I left it downloading, and came back to find it was still downloading, even though the (real) file size on my local disk was up to 5.6GB. Not good when the actual file is 2.8GB. It seems to have just not realized that the file was complete, and was just adding to it in a loop. I've tested downloading this same file using CuteFTP, and that worked perfectly.

I've tested the ItemInfo action of the FTP system, and its also broken i.e. its reporting a negative size for the 2.8gb file, in fact its reporting -1255mb, which is totally out of whack.

I've also considered using an externail open source FTP system. But thats just not viable. No way of getting any info back into AMS as to the download progress and so on. It would also basically require me to write a whole suite of wrappers to get what I really should be getting with AMS out of the box.

This looks like a show-stopper bug with the FTP plugin (a standard feature of AMS 7+). There is also another bug with the Download callback system that someone else has reported I guess. i.e. If you return FALSE to the Download action, its meant to abort the download (a useful feature). However, this does not work at all. So right now, the only way to abort a download is to disconnect from the server totally. Which is not ideal.

Looks like the FTP plugin needs some serious love from the AMS coders?

VERY COOL plugin ... I tried it. Connecting works but I'm having trouble with upload and download codes :/ . Can anyone plz offer me an upload/download example for an actual file ? Help would be appreciated . Thanks in advance
