This is the same as error as I got when the remote host was
refusing "sshd" logins.  The read() call fails in sshconnect.c
with this (or wierder) messages. If the daemon was compiled with
LIBWRAP, make sure it allows sshd (ie. if your hosts.deny
is set to deny everything by default, you must enable sshd.
Enabling rshd won't work in this case.)

ie.  (in /etc/hosts.allow):
sshd       : hostname.at.domain : ALLOW

I brought this up recently, and this is another case of the
strange diagnostic messages that occur due to using LIBWRAP.

If I get time this weekend, I'll code and submit a patch to
make the diagnostic a bit clearer.
