Re: Ping via FTP?

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Really all you need to do to see if the FTP server is up is make a socket
connection to the FTP port (port 21) of the server in question.   Once
the connection has been made, simply close it right away.

For information on sockets programming in RPG:

Another way would be to use my FTPAPI package (open source/free of charge)
to do an FTP_Conn() followed by an FTP_quit.

Either of these would be a lot more robust, and (once you got over the
learning curve) easier than trying to do it with an FTP script, because
you wouldn't have to parse the output.

Good Luck!
