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 <[email protected]>"
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 <[email protected]>" -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?
Perhaps instead of:
-a "From: someone <[email protected]>" -a "Content-Type: text/plain; charset=UTF-8"
Try:
-a "'From: someone <[email protected]>'; 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:
I receive
stderr line 01: /bin/sh: 1: Syntax error: Unterminated quoted string

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

Is this the output when running independently ?
The more detailed information you provide, the quicker your problem can be resolved.

Successfull received mail, but it's not taking the arguments after
-a. The mail is from
[email protected] with content "текÑÑ‚ на кирилица".
Successfull received mail with successfull taken argument "From" and "Content-Type".
The mail is from
[email protected] 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 <[email protected]>" $CONTACTEMAIL$

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: [email protected] <[email protected]>" -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.

Hmm, can I have you try changing it to single quotes
Code: Select all
-a 'Content-Type: text/plain; charset=UTF-8'

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...
