FTP Problems

Steven Cage — Thu, 10 Jun 2004 03:58:15 GMT

We are running OpenVMS Version 7.3-1 with TCPIP Services V5.3-18 and TCPIP_ECO V5.3-184.
We have a problem while trying to pull files from the server using FTP. Sometimes the copied file is created empty and other times complete. It is intermittent however when we run a protocol analyzer the ftp control session appears to be shutting down the connection before the data has been sent. On an OpenVMS system running version 7.2-1 and TCPIP Version 5.1 the packet sequence appears to be correct and the ftp works every time! any ideas? . Thanks in advance, Steve Cage

We had a simular problem caused by firewalls.
We added ipport_userreserved_min 5=51001 and ipport_userreserved=59999 to sysconfigtab.dat.

Reason was that the firewall was sending us a reset package (which seemed to come from the other side) because the port used by ftp was used by other sessions on the firewall (note that this is a bug). Maybe your 7.2-1 is using other port number.
