I am trying to setup a Kickstart server and when I am trying to restart the dhcpd server after having updated dhcpd.conf it is throwing a failed error. I am installing the Kickstart server on a CentOS machine which is installed as a Virtual Machine on Oracle VirtualBox. I have bridged the network of the machine and the network of the virtual machine:[root@server1 ~]# ifconfigeth0      Link encap:Ethernet  HWaddr 08:00:27:56:0D:1A          inet addr:192.168.1.29  Bcast:192.168.1.255  Mask:255.255.255.0          inet6 addr: fe80::a00:27ff:fe56:d1a/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:66790 errors:0 dropped:0 overruns:0 frame:0          TX packets:20761 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:73822713 (70.4 MiB)  TX bytes:2525478 (2.4 MiB)lo        Link encap:Local Loopback          inet addr:127.0.0.1  Mask:255.0.0.0          inet6 addr: ::1/128 Scope:Host          UP LOOPBACK RUNNING  MTU:65536  Metric:1          RX packets:97 errors:0 dropped:0 overruns:0 frame:0          TX packets:97 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:7083 (6.9 KiB)  TX bytes:7083 (6.9 KiB)The dhcpd.conf file I'm trying to update:[root@server1 ~]# vi /etc/dhcp/dhcpd.conf#   see /usr/share/doc/dhcp*/dhcpd.conf.sample#   see 'man 5 dhcpd.conf'#class PXE {    match if substring(option vendor-class-identifier, 0, 9) = PXEClient;    option vendor-class-identifier PXEClient;    vendor-option-space PXE;    next-server 192.168.179.128;    filename = pxelinux.0;}server-identifier    192.168.179.128;subnet 192.168.179.0  netmask 255.255.255.0 {range dynamic-bootp 192.168.179.125  192.168.179.225;#option routers 1.2.3.1;#option broadcast-address 1.2.3.225;default-lease-time 600;max-lease-time 7200;next-server 192.168.179.128;filename pxelinux.0;}
