Here is my setup:

  • windows 7
  • filezilla server installed on my local PC
  • filezilla client installed on my local PC
  • firewall disabled (just during the test)

Server and Client seems to work fine (I can connect and browse files with the client as expected).

I try to run the following commands

RETR /fileSource.txt

(/fileSource.txt exists on the server)

Here is the output (server side)

(000038)18/03/2013 12:56:34 - andro (> PASV
(000038)18/03/2013 12:56:34 - andro (> 227 Entering Passive Mode (127,0,0,1,231,249)
(000038)18/03/2013 12:56:39 - andro (> RETR /fileSource.txt
(000038)18/03/2013 12:56:44 - andro (> 425 Can't open data connection.

So my problem if of course this error 425 Can't open data connection

Googling around leads me to disabling firewall (to be sure it wasn't the cause) without success.

Other common issue related is ACTIVE/PASSIVE mode. As far as I understand: PASV will tell the server to switch to passive mode. (note that if I don't run PASV, I have the following error : 503 Bad sequence of commands... and it seems OK since RETR requires the passive mode. Is it correct ?)

Any idea what can be wrong ?

Note: I run in exact same issue when I do those calls from my android device (on the same LAN), so I guess this is something wrong on the server side

I think the Firewall you think is off is not really off... – Pat Mar 21 '13 at 14:07
maybe... any idea how can I check that (I'm really not a windows expert) – ben75 Mar 21 '13 at 14:12
you are already doing it; your FTP transfer opens the control channel but it cannot open the data channel. Stop the firewall next you start the FTP Server then you try the transfer... – Pat Mar 21 '13 at 14:18
