The FTP server received a PASV or EPSV command requesting that the server open a passive data connection (server does the “listen” rather than the “connect”). The server was unable to open the passive connection.
The command is rejected. FTP continues.
None.
If necessary, re-create the problem with FTP server trace active. The open data connection error will create a trace record with a socket function return code. Determine the cause of the socket error and correct the problem.
