Re: FTP with resume on IBMi

FTP is not great protocol but we are stuck with it. We were thinking of
using something like WinSCP on the Windows client so that at least it could
resume a failed transfer. Well that is what is documented

FTP is a great protocol when it comes to sheer speed. Nothing can beat FTP. That's because it's clear text. Drawback is, it's clear text, so tapping to get a copy of data in transfer is possible.

Make yourself accustomed to the FTP REST command:

HELP REST
214 REST marker: restart data transfer at this marker.

(from a telnet session to my AS/400 FTP server)

Usually, FTP command line clients implement this as reput and reget commands. If not, you'll need to calculate the needed offset by yourself, send a REST with the offset and then get or put. See documentation if your particular client implementation.
