Error

[cenzo]

I have a ftp server setup and no users have trouble uploding or downloading.

When one of my users tries to use flashfxp he can upload part of the file and then gets this error:


426 Data connection closed, file transfer test.r38 aborted.


1/4th of the files go through fine.

3/4 get truncated. at random file sizes less then full.


I am behind a linksys router with the latest firmware. I have the server working fine all except for fxp and file sizes.

Any ideas?

thanks in advance

The user using FlashFXP to FXP a file from another site to your site, I take it?

Try and find out if the file fails after some set amount of time. Perhaps you have some Anti-Idle settings on your server that are causing the transfer to fail, because the Control Connection is being considered as "idle" when no Data Activity is coming from that user's same IP address. Some FTP servers use different methods of tracking a user's idle time, and By IP Address is one of those methods, even if they did initiate the FXP transfer.

Hey,

I'm the user who's trying to FXP to Cenzo's server, I get this error even from my work PC so I'm ruling out my PC as bring the problem (sorry Cenzo :D). I'm using FlashFXP version 2.0 (Build 906). I FXP for Europe, and Cenzo's FTP is the only one I ever get this 426 error with, I use the same version of Flash at work.

All the source sites are other 3rd party offices which I have no control over the settings on. But I continually FXP from these servers to other sources running different kinds of servers, with no problem.

Have tried doing all possible combinations of the settings; PASV mode on/off, NAT/Non-Routable IP on/off, alternative upload.

I've not got much hair left and this isn't aiding the matter! :)

without seeing complete status log and knowing sHaRpEy's network setup, it does seem like cenzo's router is closing the connection..

[sHaRpEy]

Okies sorry, I'm gathering some logs right now for ya....

We tried using a diff ftp server, serv-u instead of g6 but same problem.

Some files go fine, most stop at differing sizes.

I have a linksys befsr41 with the 1.44.2, Dec 13 2002 firmware.

I run a ftp server with no other users reporting problems.

Im not sure any of the other users are using fxp or not.

I use a dynamic dns service b/c of my changing ip address. Could that have something to do with it?

I play everquest behind the same router and dont lag or go Link Dead often.

I have ports 5000-6000 for the ftp server and have it set to use them. I have 420 as the main ftp port.

What info can I get for you to allow you to better help us?
Im eager to resolve this.

I have a linksys befsr41 with the most recent firmware

Don't just say you have the latest version! lol :D

PASV

This is what it does on EVERY file, and it seems to be at random stages, not after any given filesize.

At home I am directly connected to the internet with no outgoing filters on my firewall software, at work I'm behind CheckPoint Firewall-1 running on a Nokia unit.

Operating system here is Win2K SP3, at work is Win2K Server.

Cheers.

In addition, the last lot of files I tried to upload to Cenzo, all seem to have stopped uploading around the 2-2.5Mb mark if that's of any help?! :confused:

enable time stamping, right click on the status window and select timestamp. check the time between when the transfer starts and when it fails..

[sHaRpEy]

Will do....cheers.

Here's an example

[bigstar]

do all of the transfers fail roughly 2 minutes after they start?

[sHaRpEy]

Well obviously that's gonna depend on the speed both ends, but it seem to be around the 2Mb mark after more observation, speeds are normally around the 40-50k/sec mark on average.

[bigstar]

Well if the time between each failiure was uniform that would point more towards a router/firewall closing the connection after a givin amount of time has passed. A router/firewall can only manage so many connections at any givin time dropping connections to make room for new ones.

With my linksys router if I run The All-Seeing Eye (game scanner) after a minute of scanning for activate game servers all my other activate connections get dropped by the router.

[sHaRpEy]

Sounds very feasible, I've always thought it was Cenzo's router but he won't listen to me! ;)

I refer to my earlier post (http://forum.flashfxp.com/showthread.php?s=&postid=13372#post13372) regarding control connection idle-timeout.

Over to you Cenzo! I would also like to add that this problem doesn't occur when you upload directly to his site, so it seems something is causing a timeout when FXP'ing.

I guess it does not get fixed then. No other users have any problems except this user. The router is setup correctly as is the server software.


Im not buying a new/diff router just for this fxp program that wont play nicely even though every other transfer program on the planet works flawlessly.

[sHaRpEy]

I could always move to NY, and walk the stuff round? :D

[cenzo]

Well, there are many posts on this topic and not many solutions that are working.

The programmers should create a setting to retry transfers until they are completed by chking the host and remote sizes of files and keep retrying them until the files sizes match.

Now im stuck with this unsolveable problem and my client thats connecting to me is forced to manually retry over and over the files until they are full size.

Anyone know of any other programs like this one that works with linksys routers or have size matching and/or more control for problems like this?

[sHaRpEy]

I could always try a few files with SmartFTP, didn't actually think of changing the client. Shame if it does, cos Flash ownz! :(
