How Does One force Use of DSA Keys under Linux?

[Martin McCormick <martin@dc.cis.okstate.edu>]

	I recently needed to clear out some old entries from the
.ssh/known_hosts file on a Debian system and discovered that I
couldn't tell which system key was which because they were all
type rsa keys instead of the type DSA keys which do contain a
field with either the host name or its IP address.

Is there a way in Linux to make ssh get the type DSA host keys?
I presently see the following message when adding a new host to
known_hosts:

Warning: Permanently added 'remote.host.okstate.edu,192.168.8.9' (RSA)
 to the list of known hosts.

	When a FreeBSD system connects to a Debian host as an
example, it automatically knows to add the dsa host key.

	This is no show stopper by any means, but why is this
happening? Thanks.
