check_smtp | Return code of 127 is out of bounds

Hi.
When using check_smtp, I am getting this Message:
Return code of 127 is out of bounds - plugin may be missing
When I trigger the check from cli, I get this:
root@mail-2018:~# /usr/lib/nagios/plugins/check_smtp -H localhost --port 25
SMTP OK - 0,043 sec. response time|time=0,042863s;;;0,000000
So I think the Plugin is not missing.
What am I doing wrong?
Thanks,
Steffi

Couple of things that could cause this.
1. A permission issue. When nagios runs a plugin, it runs it as the nagios user and of the permissions for the plugin are not set for the nagios user, it could generate that error.
To set the permissions, run the following as root.
Code: Select all
chown nagios.nagios /usr/lib/nagios/plugins/check_smtp
chmod a+x /usr/lib/nagios/plugins/check_smtp
2. The command is using the $USER1$ macro for the plugin's path on the file system.
Make sure the $USER1$ macro in the resource.cfg file is set to
If not, update it and restart nagios for the change to take effect.

Thanks for taking care of my issue.
I double checked what you mentionend, but it was all set:
Code: Select all
# Sets $USER1$ to be the path to the plugins
$USER1$=/usr/lib/nagios/plugins
root@mail-2018:~# ll /usr/lib/nagios/plugins/check_smtp
-rwxr-xr-x 1 root root 72592 Feb 6 2018 /usr/lib/nagios/plugins/check_smtp*
It is not working still.

Try running the plugin as the nagios user and echo out the status so we can see what it is.
Try running this in a shell. Post the full output.
Code: Select all
su - nagios
/usr/lib/nagios/plugins/check_smtp -H localhost --port 25
echo $?
Thanks.

@steffi, In the service definition that you posted you have | sign instead of ! dividing arguments. Look at the line:
check_command check_smtpd_25!localhost|25
You need to replace |with !
check_command check_smtpd_25!localhost!25
Code: Select all
define service {
host_name localhost
service_description smtpd-25
check_period 24x7
check_command check_smtpd_25!localhost|25
contact_groups admins
notification_period 24x7
