#1250 closed Bug report

Cannot get directory listing from z/VM 5.1 (implicit SSL)

Description

I am trying to make a connection to an IBM z890 mainframe running z/VM 5.1 with implicit SSL/TLS encryption. After the connection is made, a 'LIST -a' command is sent to get the directory listing. '-a' is invalid on a z/VM server. Filezilla does not send a
'-a' operand to a z/OS server with explicit TLS. Why is the '-a' used for FTP with implicit SSL/FTP? Is this some requirement of implicit SSL/TLS that IBM is ignoring?
