how to enable hooks to run before & after dhcp

SUSE Linux Enterprise Server SLES Networking
1

Hello,
I am new to SUSE and having a lot of trouble finding out how to run hooks (scripts) before & after dhcpclient is run.

I have been able to do this with other distros, but cannot figure out with SUSE, I am running SUSE 12.

I have placed my scripts in the following location, but they are not called.

/etc/dhcp/dhclient-enter-hooks
/etc/dhcp/dhclient-exit-hooks
/etc/dhcp/dhclient-enter-hooks.d/dhclient-enter-hooks
/etc/dhcp/dhclient-exit-hook.d/dhclient-exit-hooks

If I ran ps ax|grep dhcp, I get

784 ? SLs 0:00 /usr/lib/wicked/bin/wickedd-dhcp4 --systemd --foreground
785 ? SLs 0:00 /usr/lib/wicked/bin/wickedd-dhcp6 --systemd --foreground

I try to find out where wickedd-dhcp4 looks for before & after scripts, no luck so far.
I will need to configure this from the Linux shell.
Any help will be appreciated.

Thanks

Usman

Hi and welcome to the Forum :slight_smile:
You can see what the systemd service is about via cat (eg config files) for example;

systemctl cat wickedd-dhcp4

Most of the configs/scripts are down in /etc/sysconfig/network
