Dhclient.conf
Hi all :-)
on CentOS 6 I need keep the hostname from a dhcp server:
cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR :50:56:27:0E:C8
TYPE=Ethernet UUID 924b21-e92a-4944-a054-06d1967155c1
ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp PEERDNS=yes
with this config, CentOS keep only ip from dhcp server (not gw, not dns)
where is dhclient.conf? I need to create it? If yes, where’re the default options?
thanks for help!

Hi,
In DHCP server all this parameters (like DNS, GW, Netmask) have to be configure first. if you want to set the default options for GW and DNS then please do the changes in DHCP server like below.
Here is the example of dhcpd.conf file,
#
# DHCP Server Config File
#
ddns-update-style none;
ignore client-updates;
lease-file-name “/var/lib/dhcpd/dhcpd.leases”;
authoritative;
option domain-name “example.com”;
default-lease-time 86400; # 24 hours max-lease-time 172800; # 48 hours
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option domain-name-servers 192.168.1.1;
option ntp-servers 192.168.1.1;
range 192.168.1.101 192.168.1.200;
}

The dhclient.conf file doesn’t exist by default in more modern versions of CentOS. You’ll need to create it in /etc/dhcp, or by putting the requested options in /etc/dhcp/dhclient.d
For CentOS 7, it should be safe to use http://pkgs.fedoraproject.org/cgit/dhcp.git/plain/README.dhclient.d as guidelines should you choose the latter route.
