Achieve the goal: 2 Linux systems, 2 clients in the virtual machine communicate, and can ping through the host name
Lab Preparation: 1.2 Linux systems, one Win7, one win2008 in the virtual machine
2.linuxA and LINUXB as 2 routers, Win7 and win2008 as 2-terminal clients
3.2 Linux installed with one NIC device
Introduction: This experiment uses Cisco routing switching technology.
The access path to the experiment we are implementing is as follows:
Client win7----->linux A----->linux B-----> Client win2008
And the implementation can also achieve communication by pinging the host name
In a virtual machine, be sure to set the client and Linux a network interface eth0 on the same VM segment 5
Set the network interface for Linux a eth1 and Linux B network interface eth0 on the same network segment VM6
set the network interface for Linux b eth1 and client 2008 on the same network segment VM7
The purpose of the above is to separate 2 routers (Linux system to act as) and 2 clients, otherwise the same network segment VM, without the configuration of two clients can communicate, the experiment is worthless.
Experimental process:
Client Win7 Configuration
Client Win7 network address configuration see attachment map Win7network
The client win7hosts folder also needs to configure// Configure DNS resolution domain names, which are configured in this Hosts file earlier in the DNS
DNS, we do experiments for the first use this, see annex diagram win7hosts
LINUX a configuration details
[[Email protected]~]# vim/etc/sysconfig/network-scripts/ifcfg-eth0//Configure the NIC interface for Linux a eth0 IP ground
192.168.1.254 as well as the mask 255.255.255.0 and the set does not automatically get the IP to none. See annex Figure 1
[[Email protected]~]# vim/etc/sysconfig/network-scripts/ifcfg-eth1//Configure the NIC interface for Linux a eth1 IP ground
192.168.2.1 as well as the mask 255.255.255.0 and the set does not automatically get the IP to none. See annex Figure 2

[[Email protected]~]# vim/etc/sysctl.conf//Turn Linux A on the routing feature configuration see attachment Figure 5

[[Email protected] ~]# Service Network restart//Restart network services for configuration to take effect and generate IP, mask and routing table
[[Email protected]~] #ifconfig//Verify that the configuration is correct primarily view the configuration of the NIC device eth0 and eth1
[[Email protected]~]# chkconfig Network on//Let network start with system boot
LINUX B Configuration Details
[[Email protected]~]# vim/etc/sysconfig/network-scripts/ifcfg-eth0//Configure the NIC interface of Linux b eth0 IP ground
192.168.2.2 as well as the mask 255.255.255.0 and the set does not automatically get the IP to none. See annex Figure 7
[[Email protected]~]# vim/etc/sysconfig/network-scripts/ifcfg-eth1//Configure the NIC interface of Linux b eth1 IP ground
10.0.0.2 as well as the mask 255.255.255.0 and the set does not automatically get the IP to none. See annex Figure 8
[[Email protected]~]# vim/etc/sysconfig/network//configure Linux B host name see Figure 9

Client win2008 Configuration
Client win2008 network address configuration see attachment map Win2008network
Client win2008hosts folder also needs to configure// Configure DNS resolution domain name , see annex Diagram win2008hosts
Witness the moment of miracles:
Start cmd in the client Win7, use command tracert to track whether our client Win7 's routing table pings the client win2008 as we think . and using the client win7 to ping LINUX B's hostname,
The results are shown in the Appendix "Experimental Verification"
Pure hand fight!!!
