Bonjour,
je n’arrive pas à faire tourner mon serveur DHCP (isc-dhcp-server) sur une vm debian 12 qui tourne sur mon synology. j’ai juste mis le ssh et les outils réseaux, les 2 dernières cases lors de l’install avec l’image debian-12.5.0-amd64-netinst.iso (et puis sudo aussi pour faire un peu moins d’âneries).
j’ai mis le serveur DNS ( bind9 + dnsutil ) qui pointe sur ma livebox (192.168.92.20) pour créer un domaine local appelé piock.loc
lancé aa-teardown pour désactiver appamor
Et Paf le chien…:
# /etc/init.d/isc-dhcp-server start

Job for isc-dhcp-server.service failed because the control process exited with error code.
See "systemctl status isc-dhcp-server.service" and "journalctl -xeu isc-dhcp-server.service" for details.
failed!
