Code: Select all

root@maestro:/usr/lib/nagios/plugins# cat nagios.cfg | grep nagios_user
cat: nagios.cfg: No such file or directory
root@maestro:/usr/lib/nagios/plugins# cat nagios.cfg | grep nagios_group
cat: nagios.cfg: No such file or directory
root@maestro:/usr/lib/nagios/plugins# 

i think because this nagios was implemented ( not by me ) with root user!

check nagios user is available in your system ???

root@maestro:/etc/nagios3# id nagios
uid=121(nagios) gid=124(nagios) groups=124(nagios)

Switch to nagios user and run command by nagios user.

root@maestro:/etc/nagios3# su - nagios
root@maestro:/etc/nagios3# su - nagios
root@maestro:/etc/nagios3# su - nagios

define command{
command_name check_nagios_ssh
command_line /usr/lib/nagios/plugins/check_by_ssh -H $HOSTADDRESS$ -p $ARG1$ -l $ARG2$ -C $ARG3$
}

The clue is in the error message "Port must be a positive integer"

The problem is the service definition - $ARG1$ is passing "2022" to the command, which is used as the value for the option -H, which should be the host address or name. You're passing "root" as $ARG2$ which is sent to the plugin as the value for -p, hence the error message.

Update your service definition to:

Code: Select all

    define service {
            use generic-service
            host_name backups
            service_description Nagios Status
            check_command check_nagios_ssh!$HOSTADDRESS$!2022!root!"/usr/local/nagios/libexec/check_nagios -t 20 -e 5 -F /usr/local/nagios/var/nagios.log -C /usr/local/nagios/bin/nagios"
    }

I'm trying to implement a remote command from a nagios (let's call it for convenience nagios A ) to the new nagios on ubuntu server 12.04 lts (nagios B) (this nagios on ubuntu server , was done , with the precious help of this forum )
anyway i want to implement a simple command that control my nagios.log (on remote server nagios B)
i have just put the public key in authorized_keys.... and the access without password... works! the nagiosA access to the nagiosB only with a specific port:

Code: Select all

ssh -p 2022 [email protected]

then i have tried the command from the command line:

Code: Select all

root@maestro: root@maestro:/etc/nagios-plugins/config# /usr/lib/nagios/plugins/check_by_ssh  -H 'intranet.xx.xx' -p '2022'  -C "/usr/local/nagios/libexec/check_nagios -F '/usr/local/nagios/var/nagios.log' -e '5' -C '/usr/local/nagios/bin/nagios'"

NAGIOS OK: 40 processes, status log updated 47 seconds ago 

ok works!
but when i try to implement this command on servece definition (for control automatically the remote nagios.log)
i got this error:

Code: Select all

backups;Nagios Status;UNKNOWN;SOFT;2;Remote command execution failed: Permission denied, please try again.

where am i wrong?

this is my command definition:

Code: Select all

define command{
        command_name    check_nagios_ssh
        command_line    /usr/lib/nagios/plugins/check_by_ssh -H '$HOSTADDRESS$' -p '$ARG4$' -C "/usr/local/nagios/libexec/check_nagios -F '$ARG1$' -e '$ARG2$' -C '$ARG3$'"
        }

this is my service definition:

Code: Select all

define service {
        use                     generic-service
        host_name               backups
        service_description     Nagios Status
        check_command           check_nagios_ssh!/usr/local/nagios/var/nagios.log!5!/usr/local/nagios/bin/nagios!2022
}

this is my host definition:

Code: Select all

define host{
        use                     generic-host            ; Name of host template to use
        host_name               backups
        alias                   Server Nagios
        address                 intranet.xx.xx
        }

Switch to nagios user then run the command I hope it will show exact problem

root@maestro:/etc/nagios3# id nagios
uid=121(nagios) gid=124(nagios) groups=124(nagios)

root@maestro:/etc/nagios3# su - nagios
root@maestro:/etc/nagios3# su - nagios
