Configuracio del DHCP – Izan lecina webㅤㅤ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎

Per configurar el servidor DHCP he instalat el servei amb la comanda

apt-get install isc-dhcp-server

I editar els següents arxius:

/etc/default/isc-dhcp-server : he afegit enp2s0.10 enp2s0.20 enp2s0.30 enp2s0.40 a la linea 17

# Defaults for isc-dhcp-server (sourced by /etc/init.d/isc-dhcp-server)

# Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf).
#DHCPDv4_CONF=/etc/dhcp/dhcpd.conf
#DHCPDv6_CONF=/etc/dhcp/dhcpd6.conf

# Path to dhcpd's PID file (default: /var/run/dhcpd.pid).
#DHCPDv4_PID=/var/run/dhcpd.pid
#DHCPDv6_PID=/var/run/dhcpd6.pid

# Additional options to start dhcpd with.
#	Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead
#OPTIONS=""

# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
#	Separate multiple interfaces with spaces, e.g. "eth0 eth1".

/etc/dhcp/dhcpd.conf : per aquest document he afegit tot el que hi ha a partir de la linea 12, tot hi que he tingut alguns problemes amb la subxarxa CLIENT40
