----------------------
Resolution: Not A Problem
> Implicit SSL issue with EFT Server
> ----------------------------------
>
> Key: NET-287
> URL: https://issues.apache.org/jira/browse/NET-287
> Project: Commons Net
> Issue Type: Bug
> Environment: I am using Windows XP sp3, and am running the demo
> version of EFT Server. If it matters, I am using Eclipse to write and run the
> code.
> Reporter: Ryan McV
>
> I am trying to write some code that will download a file from a FTPS Server.
> When I tested the code in explicit mode using the EFT Server, it works fine.
> However, when I switch over to implicit mode, I am able to connect and login,
> but when I try to download a file, It sends back a code 150 saying that it
> was about to open a data connection, but it never does. Here is the exchange:
> {noformat}
> Attempting to connect to localhost
> 220 GlobalSCAPE EFT Server (v. 6.0) * UNREGISTERED COPY *
> Connected to localhost.
> USER test
> 331 Password required for test.
> PASS 1234
> 230-This is an * UNREGISTERED COPY * of GlobalSCAPE EFT Server.
> 230-
> 230 Login OK. Proceed.
> SYST
> 215 UNIX Type: L8
> Remote System is UNIX Type: L8
> PASV
> 227 Entering Passive Mode (127,0,0,1,18,158).
> RETR test.txt
> 150 Opening ASCII mode data connection for test.txt.{noformat}
> after that, nothing happens and eventually the server times out.
> and here is the code:

> I have tested the same code on different servers,and it works fine in
> implicit and explicit modes. However the EFT Server uses a certificate and a
> key file, and all the other servers just use a cerrtificate file. Is there
> some special code I have to use in that case? Or is there some setting in the
> server that I have to set?
> Thanks in advance you for your help.
