The FTP client has received a reset packet from the remote TCPIP stack. This typically indicates one of the following:
- The FTP server is not started. Check the remote server and ensure that the server is active.
- The FTP server does not have a listen on port 21. Check the remote server and ensure it is listening on port 21. Also, check the TCPIP
settings to ensure that the server has the authority to bind to this port.
- If the FTP server is active, and has a listen on port 21, there may be a problem with the TCPIP stack such that it is resetting the inbound
connections. See informational APAR
II12014 for information on gathering component traces, and the
FTP Traces page for information on gathering client and server traces. The following data should be collected:
- An FTP Client trace taken by adding the DEBUG options INT, SOC, FLO, and ACC to the client's FTP.DATA file
- An FTP Server trace started dynamically with options SOC, FLO, and ACC
- A SYSTCPDA component trace
- A SYSTCPIP component trace with options TCP, INTERNET, PFS, and SOCKET
