[newbie] FTP Question

[TRUB]

I cannot find where to change the "Welcome" message that appears when
someone connects to my ftp server.
The existing message contains my computer name, and my address.
I would like to not display this information, although I realize they
already have the site address if they have connected.
Where and how can I modify it.
I tried changing /etc/rc.d/rc.local with little success, and cannot find a
/welcome.msg file anywhere?
