Sites To Sites Problem (fxp)

ErnestC · 08-06-2002, 08:50 PM

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]

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

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
