Problems with trap_in.php about trapdirector

[patrickpr]

Hi,
trap_in.php is a php interpreted script which needs to be executed by PHP.

So your snmptrapd.conf should contain : traphandle default < php binary > < trap_in with path >

See doc : https://github.com/patrickpr/trapdirector/blob/master/docs/01-install.md#snmptrapd-configuration

If you can't make it work, send me your snmptrapd.conf so I have a look.

Hi,
i ran into the same issue using the automated installation script.
It put the following line into snmptrapd.conf
traphandle default -a /usr/share/icingaweb2/modules/trapdirector/bin/trap_in.php

system is raspbian buster.

Hi,

There should be php binary with path instead of '-a' : can you send me the options you used with the script ?
For a quick fix, replace '-a' by php binary with path.

Hi,

i already replaced it and it worked :)

i used the command line provided in the configuration section
Automatic installation As user root, execute this script : /usr/share/icingaweb2/modules/trapdirector/bin/installer.sh -c all -d /usr/share/icingaweb2/modules/trapdirector -p -a www-data -w /etc/icingaweb2

Hi,
I will make some checks so that the value of php binary is never empty (because then the script uses '-a' as value of php binary...).
What is the result of the following command on your system :
echo '<?php echo PHP_BINARY . "\n"; ?>' | <insert your php binary here>

Because it seems that this pre-defined constant (PHP_BINARY) is empty in your case.

Hi,

this is the result. As said, i'm using raspbian buster with default packages sources.

 echo '<?php echo PHP_BINARY . "\n"; ?>' | php
 /usr/bin/php7.3
