Looks like either the execute permissions are improperly set on the script you're trying to run - via ssh - on the remote (not nagios) server, or the user that you've set up shared keys with doesn't have permission to run the command or script. The problem with shared keys and check-by-ssh is that either you've got to set up your scripts to be able to be run by a non-priveleged user, or you've got to share the root users keys . . .. g.; <div class="gmail_quote">On Mon, Jan 25, 2010 at 3:03 PM, ReynierPM <<a href="mailto:rperezm@uci.cu">rperezm@uci.cu</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi every: Some time ago I wrote a message to this list for get help in how to check Bacula over Nagios. As bacula nagios plugins use check_host_by_ssh command I configure shared key between client (monitoring server, where nagios reside) and server(bacula - server to check) and it works because I can login from Nagios Server to Bacula Server without enter any password. Now Nagios is reporting this error: Remote command execution failed: Permission denied, please try again.
