(iv) Play with Me Linux Network Service: DHCP service configuration relay Agent

Following the third part of the DHCP server setup successfully, let's do a relay proxy server configuration.

Our Virtual machine architecture

Specific reference:

(a) Play with Me Linux network services: DNS service--bind (/etc/named.conf,/var/named) settings implementation and interpretation

According to the third part, we deployed the DHCP server above the VM1, we configured the relay service on the vm2 above, the concrete content is as follows:

1. Configure more than one subnet on a file that also configures DHCP under VM1

4. When the preparation is done, we start setting the IP address of the VM2 DHCP server, which is the interface that sends the request

# Vi/etc/sysconfig/dhcrelay

1 # Command Line Options here 2 3 interfaces="eth0"45 dhcpservers="  10.10.10.10"

5. Start the DHCP Relay Agent Dhcrelay

# service Dhcrelay Start
Start dhcrelay: [OK] Note: Here simple setup can be run, that is, VM1 and vm2 to add to the other side of the route vm1: # route add-net 192.168.128. 0/24 GW 10.10.10.8vm2 on: # route add-net 10.10.10.0/24 GW 192.168.128.8 start gate forwarding function: [[email protected]root]# vi/etc/sysctl.conf ...Net.ipv4.ip_forward = 1... 6.
