Sites To Sites Problem (fxp)

[ErnestC]

My Info like this
(1) Source , Use redhat with pure-ftpd 1.0.12
(2) Dest. , any ftp server software (e.g. Serv-U)
(3) PC Run Flashfxp, Flashfxp version 1.4 / 2.0 any build

Network Structure:
(1) with firewall(support Passive/Port ) , (2) sometime port mode only server , (3) behind a router and can use PORT /PASV mode ready.


IF both side use port 21 , it 100% can't FXP , it idle and without any transfer

IF Different Port, it can run. but always incomplete size.

--------------------------------------------------------------------------------
200 TYPE is now 8-bit binary
TYPE I
200 Type set to I.
PASV
500 Unknown command
Site to Site Transfer Failed! (Attempting alternative method)
PASV
227 Entering Passive Mode (XX,XX,XX,XX,214,180) [(2)IP].
PORT XX,XX,XX,XX,214,180
200-FXP transfer: from XX,XX,XX,XX [(3)IP] to XX,XX,XX,XX [(2)IP]
200 PORT command successful
RETR Twins.mpg
150-Connecting to port 54964
150 4427.9 kbytes to download
STOR Twins.mpg
150 Data connection accepted from XX,XX,XX,XX:20 [(1)IP]; transfer starting for Twins.mpg.
226-File successfully transferred
226 5.526 seconds (measured here), 0.78 Mbytes per second
--------------------------------------------------------------------------------

then size is smaller show on (2) but the status windows show the size is right. then i try send the same file again .
then comeup
--------------------------------------------------------------------------------
226-File successfully transferred
226 0.000 seconds (measured here), 22.16 Mbytes per second
150 Data connection accepted from error:error; transfer starting for Twins.mpg.
--------------------------------------------------------------------------------

So what mode do i need to use?
is any problem on alt FXP function ?
if (2) not support PASV mode, then it can't tranfer.becasue

227 Entering Passive Mode (XX,XX,XX,XX,214,180) [(2)IP].
PORT XX,XX,XX,XX,214,180

above line show connect to private IP which is 192.XX.XX.XX

If the site is returning a lan IP then you need to enable the option "Site uses IPMASQ/NAT/Non-routable IP" for the site in the site manager.

Not all FTP servers fully support FXP, Even FXPing between the same type of ftp server can cause problems.

I am not familiar with pure-ftpd and I don't know anything about it. It could be to blame for these problem or it might be the other ftp servers.

This line below, do you know which ftp server software returned it?
150 Data connection accepted from error:error; transfer starting for Twins.mpg.

error:error has been mentioned many times on the message board and in all instances when this error appears the file ends up incomplete. This problem is caused by the ftp server but I really don't know much about it. I'm pretty much in the dark.

[ErnestC]

As i guess

150 Data connection accepted from error:error; transfer starting for Twins.mpg

I think this line is come from source ftp server( which is linux )
why i guess this is..... i try both side use windows... never come up this size & error:error problem

so if source ftp is linux , then it will have incomplete file problem.


it may be flashfxp is not ready support linux server for fxp ???

add DebugTag=1 to flashfxp.ini [main] section
it'll prefix each site in status log so you can easer determine which command comes from which side.
it would be greate if you can exactly pinpoint which ftpd gives that error:error msg.

[ErnestC]

BOTH SIDE USE PORT MODE TO CONNECT

Test FTP SERVER Software
(1) Dest (BulletProof FTP Server)
(2) Source (pure-ftpd)

=========================================
Attach the staus log file

Seen the error:error is from the Dest. ftp , or becasue of the file can't resume....

you can see that is complete transfer on the first transfer. but the size is smaller...

then give it one more go, then the error msg come up....

[Linkster]

yeah, so its bulletproof thats giving that error...hmmmm. i wonder if the problem lies with that server..

[ErnestC]

I will try more different ftp server today..

if it is the case of "BulletProof FTP Server" cause the problem,

can it be fix ???

becasue i don't know which ftp server will be good on FXP ,
so how can i 100% sure FXP can be work all the time ?

[MxxCon]

how often do you get this "error:error" error?
if you can reproduce it often?
try to use older build of FlashFXP (like 835) see if it'll make any difference

i don't know if it can be fixed. it seems like this is ftpd error. but at the same time another user said that supposedly he doesn't get this problem with another client..which i don't see how it could be possible becuase both clients do exactly same thing.

i emailed to bpftpd support with request to help, but either they are ignoring me or didn't get to my msg yet.

we'll need to troubleshoot this problem further to pinpoint exactly whos at fault.

[ErnestC]

I can 100% reproduce this error msg in all my transfer

so it is a big problem to me now.....

[bigstar]

The only foreseeable way for us to expedite this problem is for you to provide us a login for each of the ftp servers in question. Being able to reproduce the problem myself and watching exactly what's taking place is the only quick answer to this problem.

However I highly suspect the problem is with the ftp server in which case there wont be anything we can do.

[ErnestC]

I can FXP by using Cuteftp Pro 2.0
and the file size is actually same on both side.

So i don't need resume the little file and come up with error & incomplete.....

So i don't think it is ftp server problem after this little test.....

hope other people can find out the reason.....

[bigstar]

Without us being able to reproduce the problem I can honestly say we probably won't find/fix the problem.

We really need your help to solve this problem.

If you could save the session log from cuteftp and then one from FlashFXP (complete and unedited), email them to me at support@flashfxp.com so I can review them and determine what CuteFTP is doing differently, That would be a big help.
