I need to transfer some files from AIX v4.3 to OS 390 v2.1 and want to do it with an AFT account. When i tried to validate the AFT account, appeared this message:



Can you tell me how i can fix this?
Thank you

can you open up a ftp/psftp from AIX to mainframe?

I changed the port and it worked.

Thanks anyway
