Nagios 4.4.5 email alerts with encoding

[ttsvetanov]

Hello community!

I am using nagios 4.4.5 and i am receiving errors when i add argument with character encoding to my command.

This is the command:

Code: Select all

/usr/bin/printf "%b" "$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress:$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDuration: $HOSTDURATION$\nAlias: $HOSTALIAS$\n\nDate/Time: $LONGDATETIME$ \n" | /usr/bin/mail -s "**SITE1 $NOTIFICATIONTYPE$ Host $HOSTNAME$ is $HOSTSTATE$" $CONTACTEMAIL$ -a "From: someone <some@mail.com>"

And it's working fine in this way. But when i add -a "Content-Type: text/plain; charset=UTF-8"" :

Code: Select all

/usr/bin/printf "%b" "$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress:$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDuration: $HOSTDURATION$\nAlias: $HOSTALIAS$\n\nDate/Time: $LONGDATETIME$ \n" | /usr/bin/mail -s "**SITE1 $NOTIFICATIONTYPE$ Host $HOSTNAME$ is $HOSTSTATE$" $CONTACTEMAIL$ -a "From: someone <some@mail.com>" -a "Content-Type: text/plain; charset=UTF-8"

It's not sending any mail. Nagios log gives me:

wproc: stderr line 01: /bin/sh: 1: Syntax error: Unterminated quoted string

Any ideas?

Thank you!

What is the actual mail binary?

Code: Select all

ls -la /usr/bin/mail

Perhaps instead of:
-a "From: someone <some@mail.com>" -a "Content-Type: text/plain; charset=UTF-8"

Try:
-a "'From: someone <some@mail.com>'; Content-Type: text/plain; charset=UTF-8"

The first troubleshooting test I would do would be from the command line as the nagios user with all the variables expanded out. Basically lets remove Nagios from the equation and test purely the commands.

I am using sendmail.
The command is working fine executed from the command line. With:

Code: Select all

-a "'From: someone <some@mail.com>'; Content-Type: text/plain; charset=UTF-8"

I receive

stderr line 01: /bin/sh: 1: Syntax error: Unterminated quoted string

[Box293]

Can you show us the full command and output from the commands we requested.

I receive

stderr line 01: /bin/sh: 1: Syntax error: Unterminated quoted string

Is this the output when running independently ?

The more detailed information you provide, the quicker your problem can be resolved.

Code: Select all

/usr/bin/printf "%b" "текст на кирилица" | /usr/bin/mail -s "proben tekst" -a "'From: anothermail@mail.com <anothermail@mail.com>'; Content-Type: text/plain; charset=UTF-8" mymail@mail.com

Successfull received mail, but it's not taking the arguments after -a. The mail is from root@localhost.localdomaine with content "текст на кирилица".

Code: Select all

/usr/bin/printf "%b" "текст на кирилица" | /usr/bin/mail -s "proben tekst" -a "From: anothermail@mail.com <anothermail@mail.com>" -a "Content-Type: text/plain; charset=UTF-8" mymail@mail.com

Successfull received mail with successfull taken argument "From" and "Content-Type".
The mail is from anothermail@mail.com and the content is "текст на кирилица".

You need to move the -a arguments before the send to email

Code: Select all

/usr/bin/printf "%b" "$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress:$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDuration: $HOSTDURATION$\nAlias: $HOSTALIAS$\n\nDate/Time: $LONGDATETIME$ \n" | /usr/bin/mail -s "**SITE1 $NOTIFICATIONTYPE$ Host $HOSTNAME$ is $HOSTSTATE$" -a "From: someone <some@mail.com>" $CONTACTEMAIL$

[ttsvetanov]

Well i tried with the following command line:

Code: Select all

/usr/bin/printf "%b" "$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress:$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDuration: $HOSTDURATION$\nAlias: $HOSTALIAS$\n\nDate/Time: $LONGDATETIME$ \n" | /usr/bin/mail -s "**SITE1 $NOTIFICATIONTYPE$ Host $HOSTNAME$ is $HOSTSTATE$" -a "From: someone@mail.com <someone@mail.com>" -a "Content-Type: text/plain; charset=UTF-8" $CONTACTEMAIL$

Again no mail with the following in nagios.log:

wproc: stderr line 01: /bin/sh: 1: Syntax error: Unterminated quoted string

Again, when i remove

-a "Content-Type: text/plain; charset=UTF-8"

from the line, i am receiving mails.

[scottwilkerson]

Hmm, can I have you try changing it to single quotes

Code: Select all

-a 'Content-Type: text/plain; charset=UTF-8'

[ttsvetanov]

with

Code: Select all

-a 'Content-Type: text/plain; charset=UTF-8'

:

[1582317513] EXTERNAL COMMAND: SEND_CUSTOM_HOST_NOTIFICATION;$NameOfTheHost$;0;Nagios Admin;qwww

Even tried with:

Code: Select all

command_line    /usr/bin/printf "%b" "Здрасти, това тук е тестов текст на кирилица, изпратен от NAGIOS CGI." | /usr/bin/mail -a "Content-Type: text/plain; charset=UTF-8" -s "Заглавие на тестовия мейл"

And again i received unterminated quoted string...
