Hi,I have a firewall script(firewall) that I laucnh with <firewall start>Is there a way in debian 9 (with kde5 and sddm) to start this script at the boot of the linux system or at the launching of xorg or of kde5 ?

systemd units are easy to write (this is the main benefit of systemd) and can be configured run at boot time. Here is one I wrote for iptables+ip6tables (because I do not want changes to persist across boots, just clean rules on boot). You will need a different Type if your program does not exit:

$ cat /etc/iptables/iptables.service
[Unit]
Description=iptables rules
After=network.target
[Service]
Type=oneshot
ExecStart=/bin/bash -c "/sbin/iptables-restore < /etc/iptables/iptables.rules" ExecStart=/bin/bash -c "/sbin/ip6tables-restore < /etc/iptables/ip6tables.rules"
RemainAfterExit=yes
ExecStop=/sbin/iptables -F
ExecStop=/sbin/ip6tables -F
[Install]
WantedBy=multi-user.target

I enabled it with:

systemctl enable /etc/iptables/iptables.service

This should add the required symlink in /etc/systemd/system .

Kind regards,
