Xanios · 08-09-2010, 06:17 AM

Suddenly, just so suddenly it failed. x_x
HELP.

I got the mail below:

Do refer to my previous threads regarding me setting up of the email notifications.. Thanks..

Sounds to me like a DNS problem and potentially not even your end, do you get similar problems with other domains/e-mail addresses.

If you are relaying email using Gmail smtp server and sending to your internal mail account that you have setup on your internal mail server, it wont ever be relayed. How would gmail smtp know of your internal server when there is no proper DNS record set for it?
Send your notification to your gmail account and it should work.

Xanios · 08-09-2010, 08:08 AM

Hi r3sistance,

I just created a new gmail account and used that account to receive mails, and that was no problem. I'm able to receive mails. I wonder whats wrong with my previous email account. It was able to receive mails from 7th of august until yesterday. ):

Hi Chaitanya,

Sounds a little confusing, sorry >.<

What you mean by send my notification to my gmail account?

linuxlover.chaitanya · 08-09-2010, 08:14 AM

Read your previous post. That is what I meant. You would not be able to receive mails on root@server, which is your internal address. This is because you are using Gmail as relay. Gmail would not know about your internal server as you do not have DNS set up properly. But you can send to gmail address as gmail SMTP would be able to resolve it.

r3sistance · 08-09-2010, 08:18 AM

Ah, can't believe I missed that one. root@server, should have soon that one, guess I skimmed that part in error.

Hi,

So you're saying i'm sending mails to my root@server? But, how could that be? I mean, i've defined the gmail address that i want email notifications to send to, where did that root@server popped out. x_x

r3sistance · 08-09-2010, 08:24 AM

Did you configure your server to relay ALL e-mail to gmail? It could be automatic log reports or some other services trying to send information to root.

Xanios · 08-09-2010, 08:31 AM

No i guess. I only defined my gmail address in sasl_password and in contacts.cfg. What else are there?

linuxlover.chaitanya · 08-10-2010, 12:08 AM

You will need to tell nagios where it needs to send mails to and from which smtp server.

Xanios · 08-10-2010, 12:54 AM

In contacts.cfg right? in define contact..there is a email, i gave my gmail.

Code:

define contact{
        contact_name            nagiosadmin             
        use                     generic-contact         
        alias                   Nagios Admin            
        email                   xanios@gmail.com  
        }

linuxlover.chaitanya · 08-10-2010, 12:57 AM

I do not know how to do that.

EricTRA · 08-10-2010, 01:03 AM

Hi Xanios,

It looks to me that this mail is a system mail that's being sent from a deamon (cron) to the root user on your server. Since you're relaying ALL your mail to GMail you're getting this error because GMail cannot resolve your domain/host. Normally the simplest way is to create a file named .forward in your root's home directory (and maybe also in your user home directory) containing your destination email address. Like this:

Code:

root@srvnagios:~# cat .forward
user@gmail.com

root@srvnagios:~#

Not sure if you should restart postfix but it wouldn't hurt. With this 'forward' file all mails to the root user will be automagically forwarded to your gmail address.

Kind regards,

Eric

Hi Xanios,

Look at the mail you posted. It's not from Nagios!

Code:

From: Anacron <xanios@gmail.com>
To: root@server.com
Subject: Anacron job 'cron.daily' on ubuntu
Message-Id: <20100808103707.15A0B40A6B@ubuntu>
Date: Sun,  8 Aug 2010 18:37:06 +0800 (SGT)

/etc/cron.daily/logrotate:

Read my previous post and try that. If your postfix was working before then this should do the trick for your system messages.

Kind regards,

Eric
