Strange sshd problem with 1.5.3-PREVIEW
I upgraded two servers to 1.5.3-PREVIEW and noticed that although sshd is
compiled to use libwrap.so, it does not consult it (server name mangled):

ALL: 127.0.0.1 : ALLOW

However, ssh connections to XYZW are allowed and accepted.
TIA for any ideas or flames.

hm... NetBSD's libwrap has /etc/hosts.deny, so putting "ALL: ALL : DENY"
in /etc/hosts.deny could do the trick...

I am using it as described in hosts_options(5), ie. using a single file
(/etc/hosts.allow). BTW, I tried splitting it to /etc/hosts.allow and
/etc/hosts.deny (as described in hosts_access(5)) but the result is the
When I was using 1.5.0-PREVIEW it worked as expected, with 1.5.3-PREVIEW it
seems that that libwrap is not consulted, although sshd is linked to it and
the makefiles seem to define -DLIBWRAP.
