TCP/IP FTP Passive mode transfers? (PASV)

» close window

The Question is:

 
ucx 4.2 and passive ftp.
we're having trouble putting/getting files from sites
outside our firewalls. when the ftpserver wants to open
the dataport against some "random" portnumber L in our
machine, the port number L is reserved for other
purposes in a database in the firewall and thus the
connection is refused.
 
Passive ftp would, according to some solve the problem.
Does UCX ftp-client support it or will it never?
 
Thanks in advance/Hans Blom
 
 

The Answer is :

 
  RFCs relevent to FTP passive mode include RFC 1123 and RFC 959.
 
  The TCP/IP Services FTP Server can enter passive mode using QUOTE PASV
  from the (remote) client.
 
  The TCP/IP Services FTP client itself does not currently support passive
  mode operations.
 
  Passive mode can also sometimes utilize the ENABLE and DISABLE SERVICE
  FTP/PORT commands.
