I created a new FTP monitor to watch one of our internal FTP servers which does not accept anonymous FTP connections. I'm using the credential database but I'm still not having any success monitoring this FTP server.
The FTP monitor in Beta 2 requires anonymous access and the ability to do a directory listing (specifically a NLST command).
This monitor is actually doing too much. It should be connecting to the FTP server and verifying that the server responds like an FTP server (This is bug #802). At some point we may add an FTP Experience Monitor that can be configured to login to an FTP site and download a monitor.
