@sreinhardt

Can you run the following command and send back the output

the command! :

Code: Select all

nslookup -querytype=any deaconsulenze.eu
Server:		10.10.2.102
Address:	10.10.2.102#53

Non-authoritative answer:
deaconsulenze.eu	nameserver = ns2003.dizinc.com.
deaconsulenze.eu	nameserver = ns2004.dizinc.com.

Authoritative answers can be found from:

That output looks truncated, but similar to a successful name resolution.

If you did successfully resolve the MX record, then I'd next check the network - can you "telnet intra.deaconsulenze.eu 25" from the Nagios server?

[aleks1]

Authoritative answer is empty...is a good thing??

here is the command:

Code: Select all

root@backups:~# telnet intra.deaconsulenze.eu 25
Trying 144.76.118.183...
Connected to intra.deaconsulenze.eu.
Escape character is '^]'.
220 intra.deaconsulenze.eu ESMTP Postfix (Debian/GNU)

i don't know what can i do!

[Stuart Watts]

Does /var/log/maillog show any other information around the time of the failed Nagios notification?

Try sending a mail manually:

Code: Select all

telnet intra.deaconsulenze.eu 25
HELO <nagios server FQDN>  <---- (the output from "uname -n")
MAIL FROM:some.email@address.com
RCPT TO:your.email@address.com
DATA
SUBJECT:Test email
[Press Enter twice]

some data
some data
.

The last part is a single "." on a line on it's own, which tells the relay you're done sending data. Post any errors you get from doing this.

Does /var/log/maillog show any other information around the time of the failed Nagios notification?

only this:

Code: Select all

Hrm, okay.

What happens if you try:

Code: Select all

su - nagios
/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: HTTP\nHost: IpCop Milano ESA\nAddress: 192.168.33.1\nState: CRITICAL\n\nDate/Time: Thu Jun 5 14:51:10 CEST 2014\n\nAdditional Info:\n\nHTTP CRITICAL: HTTP/1.0 504 Gateway Time-out - 1937 bytes in 0,183 second response time\n" | /usr/bin/mail -s "** PROBLEM Service Alert: IpCop Milano ESA/HTTP is CRITICAL **" supporto@deaconsulenze.eu

What happens if you try:

Code: Select all

root@backups:~# su nagios
$ /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: HTTP\nHost: IpCop Milano ESA\nAddress: 192.168.33.1\nState: CRITICAL\n\nDate/Time: Thu Jun 5 14:51:10 CEST 2014\n\nAdditional Info:\n\nHTTP CRITICAL: HTTP/1.0 504 Gateway Time-out - 1937 bytes in 0,183 second response time\n" | /usr/bin/mail -s "** PROBLEM Service Alert: IpCop Milano ESA/HTTP is CRITICAL **" supporto@deaconsulenze.eu

Additional Info:

the problem arrives to account supporto@deaconsulenze.eu!!!!
we are near the solution?

[Stuart Watts]

I'm not sure, to be honest! That command is what Nagios runs when the notification is triggered.

One very minor thing - can you "su - nagios", not "su nagios" and run the command again please?

[sreinhardt]

Just to make it a little more clear for you, Stuart would like to see:

Code: Select all

su nagios
/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: HTTP\nHost: IpCop Milano ESA\nAddress: 192.168.33.1\nState: CRITICAL\n\nDate/Time: Thu Jun 5 14:51:10 CEST 2014\n\nAdditional Info:\n\nHTTP CRITICAL: HTTP/1.0 504 Gateway Time-out - 1937 bytes in 0,183 second response time\n" | /usr/bin/mail -s "** PROBLEM Service Alert: IpCop Milano ESA/HTTP is CRITICAL **" supporto@deaconsulenze.eu

[eloyd]

I think he wants to see

n you "su - nagios", not "su nagios"
