[Nagiosplug-help] R: Remote command execution failed: Permissiondenied (publickey, keyboard-interactive).

[J4]

Hi Marc,

The check commands are:

# 'check_remote_procs' command definition
define command{
        command_name    check_remote_procs
        command_line    $USER1$/check_by_ssh -p $ARG1$ -l nagios -i \
/usr/local/nagios/etc/keys/$HOSTNAME$ -H $HOSTADDRESS$ -C \
'/usr/local/nagios/libexec/check_procs -w $ARG2$ -c $ARG3$ -s $ARG4$'
        }


# 'check_remote_swap' command definition
define command{
        command_name    check_remote_swap
        command_line    $USER1$/check_by_ssh -p $ARG1$ -l nagios -i \
/usr/local/nagios/etc/keys/$HOSTNAME$ -H $HOSTADDRESS$ -C \
'/usr/local/nagios/libexec/check_swap -w $ARG2$ -c $ARG3$'
        }


Note that I have added the back slash \ to the lines above in this
Email.  The key file is correctly named dd52, and I have tested this with:

root at abc:/usr/local/nagios/etc/objects# ssh -i
/usr/local/nagios/etc/keys/dd52 nagios at dd52

There are no ssh_config files in place.
