Bonjour
Bon j’ai recommencé une configuration:
/etc/dhcp # less dhcpd.conf
### Changer ces lignes
# Nom de domaine pour le reseau local
option domain-name "mondomaine.lan";
# Utilisation des DNS, si vous avez bind d'installéous pouvez spéfier les IPs (comme moi), sinon utilisez les DNS de Google
option domain-name-servers 10.1.0.254, 80.10.246.2;
# Temps durant lequel les adresses ip locales seront assigné
default-lease-time 36000;
max-lease-time 72000;
### Il faut decommenter cette ligne
authoritative;
### Ajout de l'attribution
subnet 10.1.0.0 netmask 255.255.255.0 {
# rang d'attribution
range 10.1.0.100 10.1.0.250;
# masque de sous-réau
option subnet-mask 255.255.255.0;
# broadcast pour les informations gérales
option broadcast-address 10.1.0.255;
# adresse ip du routeur
option routers 10.1.0.254;
}
### PXE ###
### Permet le boot réseau pour TFTP
allow bootp;
allow booting;
filename "pxelinux.0";
next-server 10.1.0.254;
ping-check = 1;
Bon bien sur je n’ai pas de dns derriere mais suivant ce tuto ce n’est pas indispensable: howtoforge.com/ubuntu-14.10 … stallation
Ensuite j’ai allégé dnsmasq pour enlever toutes les lignes en relation avec dhcp, ce qui fait que normalement il est en dns uniquement.
J’ai relancé ensuite dnsmasq pour qu’il soit en mode dns et démarré isc-dhcp-server.
J’ai retenté un boot via PXe, pas de soucis il trouve bien le serveur local PXE et le fichier de config, et a même soucis, et même message:
La configuration DHCP n'est probablement pas utilisé sur le réseau.Il est également possible que le serveur dhcp soit lent ou que certains équipements réseau ne fonctionne pas correctement.
voila ma config dnsmasq.conf actuelle
# Configuration file for dnsmasq.
#C'est la configuration avec DHCP
# Never forward plain names (without a dot or domain part)
domain-needed
# Never forward addresses in the non-routed address spaces.
bogus-priv
# Uncomment this to filter useless windows-originated DNS requests
# which can trigger dial-on-demand links needlessly.
# Note that (amongst other things) this blocks all SRV requests,
# so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.
# This option only affects forwarding, SRV records originating for
# dnsmasq (via srv-host= lines) are not suppressed by it.

# file, getting its servers from this file instead (see below), then
# uncomment this.

# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
# files for changes and re-read them then uncomment this.
#no-poll

# You can control how dnsmasq talks to a server: this forces
# queries to 10.1.2.3 to be routed via eth1
# server=10.1.2.3@eth1
# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
#interface=
# Or you can specify which interface _not_ to listen on
#except-interface=
# Or which to listen on by address (remember to include 127.0.0.1 if
# you use this.)
#listen-address=
# If you want dnsmasq to provide only DNS service on an interface,
# configure it as shown above, and then use the following line to
# disable DHCP on it.
#no-dhcp-interface=
# If you don't want dnsmasq to read /etc/hosts, uncomment the
# following line.
#no-hosts
# or if you want it to read another file, as well as /etc/hosts, use
# this.
addn-hosts=/etc/dnsmasq.hosts
# Set this (and domain: see below) if you want to have a domain
# automatically added to simple names in a hosts-file.
expand-hosts
# Set the domain for dnsmasq. this is optional, but if it is set, it
# does the following things.
# 1) Allows DHCP hosts to have fully qualified domain names, as long
# as the domain part matches this setting.
# 2) Sets the "domain" DHCP option thereby potentially setting the
# domain of all systems configured by DHCP
# 3) Provides the domain part for "expand-hosts"
