Hallo,
beim Neustart von meinen Rechner startet der dhcp Server nicht mit. Wenn ich das Skript per Hand ausführe erhalte ich folgende Fehlermeldung:
Es läuft aber kein anderer DHCP Server an diesen Server und in diesen Netzwerk.
Der Auszug aus der rc.conf sieht wie folgt aus.
Mein dhcpd.conf hat folgenden Inhalt:
Wenn ich den Befehl "/usr/local/sbin/dhcpd" auf der Shell ausführe, dann wird der dhcp Server gestartet.
Über das run Skript im rc.d Verzeichnis wird er nicht gestartet.
Run-Script:
Wo liegt der Fehler?
Danke Daniel

There's already a DHCP server running.Es läuft aber kein anderer DHCP Server an diesen Server und in diesen Netzwerk.
Der Auszug aus der rc.conf sieht wie folgt aus.

}Wenn ich den Befehl "/usr/local/sbin/dhcpd" auf der Shell ausführe, dann wird der dhcp Server gestartet.
Über das run Skript im rc.d Verzeichnis wird er nicht gestartet.
