Demand:
1, because do cobbler test fear affect the company's normal network environment; So use VirtualBox to create a virtual machine for testing;
2, also requires the virtual machine to access the external network (install a variety of packages) but does not affect the company's DHCP server;
Solution:
Using VirtualBox to create a dual network card, Nic 1 Select Bridge, network card 2 Select the internal network;

1. Enter Linux server 1 for network card settings:
# cat Ifcfg-eth1 #查看eth1配置, be sure to fill in the MAC address, or the configuration of two network cards may conflict device=eth1type=ethernetonboot=yeshwaddr=08:00:27:72:9d : 6fnm_controlled=yesbootproto=staticipaddr=192.168.1.66netmask=255.255.255.0gateway=192.168.1.1dns1= 192.168.1.1# cat ifcfg-eth2 #查看eth2配置DEVICE =ETH2TYPE=ETHERNETONBOOT=YESHWADDR=08:00:27:97:90:AA nm_controlled= yesbootproto=staticipaddr=172.16.1.2netmask=255.255.0.0gateway=172.16.1.1
Server 2 configuration is the same, only need to modify eth2 ip=172.16.1.3 (customizable) address;
2, to test:
