Hi all :-) on centos 6 I need keep the hostname from a dhcp server: cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR=00:50:56:27:0E:C8 TYPE=Ethernet UUID=20924b21-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! Pol
