How to diagnose ftp's `connection refused' error?

   Systems: Two Alpha 2000 servers running DUNix 4.0b. Security patch 0003
            has been applied to both and the kernel was rebuilt on both.

   History: In order to avoid the ftpd security bug, ftp connections to
            both systems were disabled by making the image /usr/sbin/ftpd
            non-executable prior tothe patch install.

            After the patch install and kernel rebuilt, both systems
            appear to have gotten a new ftpd image.

   -rwxr-xr-x 1 bin bin 106496 Feb 2 19:40 /usr/sbin/ftpd

   Problem: ftp connections are accepted by one system. On the other one
            we get `connection refused' message.

   What causes this error? How can we debug & fix?

   Thanks.
