There are many issues that can occur during an FTP connection to the iSeries. Most of these issues are logged in the log file or joblog of the product that you are using.
Occasionally, however, there are errors that are extremely difficult to track down without viewing the actual communication strings that are being passed over the FTP connection.
How to Debug FTP errors
Where to Start
First and foremost, start with the joblog or log file of the product that you are using. This will typically provide all the information that you need to resolve the issue.
Viewing the FTP Logs
If that fails, you may need to view the actual FTP communication strings that are being passed.
This step requires that the connection to the FTP Server on the iSeries still be active!
If the FTP connection is still active, the iSeries will have two temporary logs sitting out in the QTEMP library that you can view.
You can use the following commands to view these logs:
DSPPFM QTEMP/FTPCMDDSPPFM QTEMP/FTPLOG
