check_by_ssh failing - host key verification failed

[O'Donnell, Robert L]

Running nagios 3.0.6 on OpenSUSE and trying to get info from a SUSE enterprise machine.

Chk_by_ssh returns UNKNOWN and "Remote command execution failed: Host key verification failed",  check_ping works.

I have played with every combo of options I could think of, but same results.  This is my first setup with remote checks on a linux machine (windows machine checks working fine), so it could be a newb problem.

(from commands.cfg)
# check_ssh_dummy command definition
define command{
     command_name          check_ssh_dummy
     command_line          $USER1$/check_by_ssh -H $HOSTADDRESS$ -l nagios -2  \
         -I /etc/nagios/.ssh/id_dsa -C "/usr/lib/nagios/plugins/check_dummy 0"
     }

I took out the desired response text to eliminate possible double quote issues, but it made no difference


(from object config)

define service{
     use                    local-service
     host_name              (machine_name)
     service_description    PING
     check_command          check_ping!100.0,20%!500.o,60%
     }

define_service{
     use                     local-service
     host_name               (machine_name)
     service_description     check_ssh_dummy!
     }


>From the command line, I run:

/usr/lib/nagios/plugins/check_by_ssh -H (machine_ip) -l nagios -i /etc/nagios.ssh/id_dsa -C "usr/lib/nagios/plugins/check_dummy 0"

It returns OK

I am having the same issue with check_ssh_disk.  I do not have a MOTD for the shell, I have tried putting explicit paths in place of USER1, putting in the actual address for HOSTADDRESS, and many options on the
