I have been working with Apache FTPServer since July. Once getting it
to work on my PC I installed it on my UNIX system here at our home
office. It works without fail in that environment. However, I then
deployed it to our production server which is behind a firewall but the
same o/s, aix. It lets me log in but it breaks down when I try to port
a file to it. The exception is as follows:
org.apache.ftpserver.IODataConnectionFactory createDataSocket
WARNING: FtpDataConnection.getDataSocket()

The problem occurs regardless of whether I use pasv mode or active mode
and it happens in the IODataConnectionFactory class when a new Socket
object is being initialized on line 268 (dataSoc = new Socket(address,
port, localAddr, localPort);
Do I need to implement a code change to fix my problem or is there a
setting that I am missing in the ftpd.properties file?
Any insight you can provide would be most appreciated.

Ralph Philistine
