Diagnosing FTP Client Connection Establishment Problems


Go to the FTP Traces page for information on collecting a client trace. A trace with options FLO, INT, ACC, and SOC will be needed. The trace should be activated via DEBUG statements in the FTP.DATA file.

A packet (SYSTCPDA) trace should also be obtained. Instructions for gathering a packet trace can be found in informational APAR II12014. Details on submitting these traces for analysis can be found in informational APAR II12030.
