Hallo an alle

Ich hab ein Problem mit dem DHCP Server Service in Webmin ich hab bei Google zwar das Problem gefunden aber geholfen hat es mir nicht

Es dreht sich darum das ich Ubuntu Server installieren dann Webmin installieren wie es auf der Offiziellen Homepage beschrieben ist

Dann bei Un used Modules den DHCP Server

und jetzt kommt das Problem es ist egal ob ich was konfiguriere oder nicht er lässt sich nicht starten.

ich hab den Server mitlerweile mehrmal neuinstallieren vieles probiert wie es in den anderen Foren beschrieben war aber ohne Erfolg

es ist eine komplette Neuinstallation, die sollte eigentlich sofort funktionieren

root@DHCP-Server:~# systemctl status isc-dhcp-server.service

edit: ich hab das mit der Fehlerbeschreibung nicht besser hin bekommen im grauen Hintergrund

könnt ihr mir da weiter helfen?

Hallo DJKUhpisse

Welche Konfigurationsdatei?

/etc/dhcp/dhcpd.conf

Ich würde auch diese nutzen und nicht irgendwelche Webadmin-Tools. So kann man den Fehler eingrenzen.

# dhcpd.conf # # Sample configuration file for ISC dhcpd # configuration file instead of this file. #

sorry war ein Fehler

Gib mit cat den Inhalt aus.

oh okay sorry habe eben raus gefunden wie das geht

Das ist ja gar nichts konfiguriert. Was soll denn konfiguriert werden?

Hallo DJKUhpisse

es soll jetzt nichts spezielles werden zum einem sollen alle bekannten Geräte eine Feste IP Adresse bekommen alle nicht bekannten Geräte sollen in einem Bereich von 192.168.0.200 bis 192.168.0.250 und alle Geräte sollen den DNS Server 192.168.0.5 und den Router 192.168.0.2 vom DHCP gesagt bekommen

Dann konfiguriere das in der Datei. https://wiki.ubuntuusers.de/ISC-DHCPD/

Hallo DJKUhpisse

Ich hab den Server jetzt mit Debian 11 installiert und Webmin drauf Jetzt funktioniert er sofort auch ohne das ich was vor konfigurieren muss ich hab während dem laufen alles erstellen und konfiguriert was ich gebrauche und dann gespeicher und bestätigt es hat alles funktioniert ich weiß nicht warum es nicht mit dem Ubuntu Server funktioniert hat aber auf Debian gehts

aber vielen dank für die Hilfe ich hoffe es hilft hier anderen weiter meine Lösung ich schließe das Thema jetzt als gelöst
