Linux virtual bridge experiment
A, experimental background
bridge: a plurality of LAN data link layer connected together to achieve mutual communication between LAN. At the same time the broadcast can be isolated
experiment procedure
Before the experiment only one computer can access, after the experiment, two computers can access.
First of all -> Virtual Network Editor -> Add network -> VMnet3 host-only mode
to view IP: ifconfig route also remember that behind the configuration required to use.
(1) pc1 virtual bridge to install the software:
sudo apt-get install bridge-utils
(2) network-manager uninstall
sudo apt-get purge network-manager
(3) modify the network card configuration:
sudo gedit /etc/network/interfaces
Add the following (remember to modify it):
auto eth0
iface eth0 inet static
address 0.0.0.0
auto eth1
iface eth1 inet static
address 0.0.0.0
auto br0
iface br0 inet static
address 192.168.206.128
netmask 255.255.255.0
gateway 192.168.206.2
broadcast 192.168.206.255
dns-nameservers 192.168.206.2 192.168.30.1
bridge_ports eth0 eth1
pc1 Adding Bridge
sudo brctl addbr br0
Restart Interface
sudo ifdown br0 && ifup br0
pc2 uninstall network-manager:
sudo apt-get purge network-manager
pc2 configure a static ip:
sudo gedit /etc/network/interfaces
Add the following:
auto eth0
iface eth0 inet static
address 192.168.206.129
netmask 255.255.255.0
gateway 192.168.206.2
broadcast 192.168.206.255
dns-nameservers 192.168.206.2
