Indeed. The problems arise when clients make unwarranted assumptions
about the format about the format of the reply to LIST/NLST and behave
accordingly. The conservative and safe behavior is to display the reply on
the client console and let the presumably informed user act properly.
RFC 959 does not, in fact can not, dictate the format of the reply to LIST.
I believe that some mainframe servers have an option (SITE command)
to set the format of LIST to simulated desktop format to support
presumptuous clients.
an idiosyncrasy I noticed with the MVS FTP client is the sequence:
lcd whatever
! pwd
displays, not the target of the "lcd" but the directory from which FTP
was entered. Apparently the client never bothers to do a "chdir()"
as I expect from other systems.
