Ports in FTP-APIs

["Werner Noll, GEFIS" <werner.noll@xxxxxxxxx>]

   Hi all,


   we do not specify the port parameter in FTP_Conn API, but I wonder why
   the last 2 ports in the port list (seen in the job log) are always
   different?


   e.g.: PORT 10,12,40,21,139,131

           PORT 10,12,40,21,137,102

           PORT 10,12,40,21,141,21

           PORT 10,12,40,21,142,8


   Some firewalls restrict the port numbers and therefore we get
   sometimes errors, if an invalid port is used. Therefore my second
   question: Which port of the port list will be actually used? Is it
   recommended to specify certain ports in FTP_Conn parameter?


   Many thanks in advance.
