Yes.

This is how an ssh/sftp client talks to an ssh server.  It connects,
waits for the SSH-* banner, then sends its own SSH-* banner.

It looks for a banner that starts with "SSH".  It looks only in the
banner for this string.

The "banner" line causes Xymon to log what it receives from the
server, but before sending the "send" string.  All of the other data
should not be logged.
