I don't know why you have "/usr/bin/sendmail" when I would expect it to be "/bin/mail" or maybe "/usr/bin/mail"

Try changing that in your command.cfg (or appropriate Nagios config file) and see if that works. I think you're trying to send mail incorrectly.

Also, you can try sending a test email from the CLI:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]

Hi! and sorry for later answer!
when i try to use this command:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]

i got this:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]        
sh: 1: mail: not found

but with this:

Code: Select all

echo "test" | sendmail -s "test mail" [email protected]

i got this:

Code: Select all

WARNING: RunAsUser for MSP ignored, check group ids (egid=1006, want=116)
can not chdir(/var/spool/mqueue-client/): Permission denied
Program mode requires special privileges, e.g., root or TrustedUser.

with a root user this last command the test mail... work!

how can i fix this permission denied issue?
or i must install a programm for example mail?

thanks in advance!

I have tried to install mail (apt-get install mailutils)

Try changing that in your command.cfg (or appropriate Nagios config file) and see if that works. I think you're trying to send mail incorrectly.

and now i have changed the path in command .cfg in:
# 'notify-host-by-email' command definition

Code: Select all

define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
        }

# 'notify-service-by-email' command definition
define command{
        command_name    notify-service-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }

i have tried to execute this command with nagios user:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]

and the test mail..work!
but unfortunatly no automatically mail notification from nagios yet

Any help be appreciate!

[scottwilkerson]

Can we verify what the full path to mail is

Code: Select all

which mail

also, you would need to make sure you restarted the nagios process after changing the commands ad you had.

[aleks1]

thank you for reply!
the command which mail returns:

Code: Select all

which mail

/usr/bin/mail

the right path! in command.cfg there is this path...
yeah i have restarted 3 times the nagios process ehehe
but i don't receive any notification mails yet

[aleks1]

In /var/log/mail.log

i have this:

Code: Select all

My unqualified host name (backups) unknown; sleeping for retry

Your machine is not set up to properly recognize itself. You need to add your IP address and name to /etc/hosts or a DNS server.

[aleks1]

hi eloyd! and thanks for reply!

Your machine is not set up to properly recognize itself. You need to add your IP address and name to /etc/hosts or a DNS server.

in /etc/hosts i have these lines:

Code: Select all

127.0.0.1       localhost
127.0.0.1       backups

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

what i should add?
sorry for my unexperience!
