Hi did you check your miscommands.cfg?is it ok?
also check out the permission on mail script in /bin/mail

Thanks

what priv’s are they supposed to have ?? here is what i got

-rw-rw-r-- 1 nagios nagios 4248 Jun 3 15:51 misccommands.cfg

-rwxr-xr-x 1 root mail 73588 Jun 15 2004 /bin/mail

???

somebody please helllllllllllllllllllllllpppppppppppppppppppppppppp

Hi
Try giving this perm’s
-rwxrwx–x
Let us know

produce the same output that nagios would, but do it by hand and see if the mail works.

From miscommands.cfg file, email is defined like this:

‘notify-by-email’ command definition

define command{
command_name notify-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: $DATETIME$\n\nAdditional Info:\n\n$OUTPUT$" | /bin/mail -s " $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **” $CONTACTEMAIL$
}

So login as nagios:
su - nagios
Send an email the way that nagios would:
/usr/bin/printf “%b” “***** Nagios ***\n\nNotification Type: testNOTIFICATIONTYPE\n\nService: testSERVICEDESC\nHost: testHOSTALIAS\nAddress: testHOSTADDRESS\nState: testSERVICESTATE\n\nDate/Time: testDATETIME\n\nAdditional Info:\n\ntestOUTPUT" | /bin/mail -s " testNOTIFICATIONTYPE alert - testHOSTALIAStestSERVICEDESC is testSERVICESTATE **” [email protected]

If you get an error, then great, you should be able to fix that.

BTW, you have to enable notifications for each an every service that you want enabled, by using the link called “Enable notifications for this service”. Do this please, even though you have enabled it in the config files. There is a good reason for this.

I am adamant that you do this, since it’s a common mistake, and I too fought this same trouble for weeks, until I read the above URL.

Ooops, sorry, but i read your first post again, and it looks like the emails are being sent but the permissions appear to be wrong on the mailque folder.

Hi…
Ok so you still are not getting emails on your configured email id right?
well what you do is check everything from start with a cool mind.

1>check whthe you have properly configured your email id on the server.

2>your nagios is running

3>check for your misscommands.cfg.in this check for the path of mail script if it is correct.

4>check the permissions on your mail script its in /bin.
check yours in /bin folder

they should be similar to as follows

-rwxr-xr-x 1 root mail 69276 Apr 12 23:29 mail*

5>stop nagios completely and then start it

6>if you still get errors check /var/log/messages and paste the output here i will again c to it

Thanks
Let me know
