General Discussion / Execute custom script on DHCP commit

« on: January 12, 2024, 02:20:12 pm »

Hi,

I'm running OPNsense 23.7.10_1.

I'm trying to execute a custom bash script when a client connects to the DHCP server.

First I've changed the file

Code: [Select]

/usr/local/etc/inc/plugins.inc.d/dhcpd.inc by adding:

Code: [Select]

$dhcpdconf .= 'on commit { execute("/etc/dhcpd/usr/local/sbin/oncommit", "commit"); }';
After DHCP restart from the GUI, the file

Code: [Select]

/var/dhcpd/etc/dhcpd.conf is well modified with the new line.

Then I create a file

Code: [Select]

/var/dhcpd/etc/dhcpd/usr/local/sbin/oncommit with 777 permission and dhcpd/dhcpd as user/group.

The result in the dhcpd log is :

Unable to execute /run/oncommit: No such file or directory

I've also try with a path that do not depend on the chroot dhcpd path with the same result.

Any help would be appreciate!
