[jira] Created: (FTPSERVER-51) PASV command returns the wrong IP address when multiple interfaces are available.

PASV command returns the wrong IP address when multiple interfaces are available.
---------------------------------------------------------------------------------

                 Key: FTPSERVER-51
                 URL: http://issues.apache.org/jira/browse/FTPSERVER-51
             Project: FtpServer
          Issue Type: Bug
            Reporter: Joseph Ferner


If the FTP server has multiple NIC interfaces and the "config.data-connection.passive.address" configuration parameter is not set the server will return the first IP address found on the server and not the IP address of the established communications.

Setting "config.data-connection.passive.address" is not a good solution because then the FTP server cannot listen on multiple IP addresses.

[jira] Updated: (FTPSERVER-51) PASV command returns the wrong IP address when multiple interfaces are available.

Joseph Ferner updated FTPSERVER-51:
-----------------------------------

    Attachment: fix.patch

First, I set the passive address to null if not specified.
I then pass the control socket's local IP address around (which really isn't that much) so that I can run a check to see if the passive address is null and if it is return the local IP address instead.
