Serverdienste - DHCP

Benötigt werden

• Der DHCP-Server (dhcpd)
• Die Konfigurationsdatei /etc/dhcpd.conf mit Einträgen für jedes verwendete Interface der Servermaschine.
• Die Datei dhcpd.leases, üblicherweise in /var/lib/dhcpd.leases (muss existieren)

Die Datei /etc/dhcpd.conf

# dhcpd.conf

# Sample configuration file for ISC dhcpd

# option definitions common to all supported networks...

# Hosts which require special configuration options can be listed in
# host statements.   If no address is specified, the address will be
# allocated dynamically (if possible), but the host-specific information
# will still come from the host declaration.

#host passacaglia {
#  hardware ethernet 0:0:c0:5d:bd:95;
#  filename "vmunix.passacaglia";
#  server-name "toccata.fugue.com";
#}

# Fixed IP addresses can also be specified for hosts.   These addresses
# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
# BOOTP or DHCP.   Hosts for which no fixed address is specified can only
# be booted with DHCP, unless there is an address range on the subnet
# to which a BOOTP client is connected which has the dynamic-bootp flag
# set.
#host k3301ps {
#  hardware ethernet 00:d0:b7:6f:13:02;
#  fixed-address 193.196.134.191;
#}

# If a DHCP or BOOTP client is mobile and might be connected to a variety
# of networks, more than one fixed address for that host can be specified.
# Hosts can have fixed addresses on some networks, but receive dynamically
# allocated address on other subnets; in order to support this, a host
# declaration for that client must be given which does not have a fixed
# address.   If a client should get different parameters depending on
# what subnet it boots on, host declarations for each such network should
# be given.   Finally, if a domain name is given for a host's fixed address
# and that domain name evaluates to more than one address, the address
# corresponding to the network to which the client is attached, if any,
# will be assigned.
#host confusia {
#  hardware ethernet 02:03:04:05:06:07;
#  fixed-address confusia-1.fugue.com, confusia-2.fugue.com;
#  filename "vmunix.confusia";
#  server-name "toccata.fugue.com";
#}

#host confusia {
#  hardware ethernet 02:03:04:05:06:07;
#  fixed-address confusia-3.fugue.com;
