After loading the driver, two devices, veth0 and veth1, will be generated. Different applications can open these two network card devices to communicate with each other (note that the network namespace of linux should be used to isolate the two devices) device so as not to enter the local loop network device). ## Install ```shell make make load ``` ## Config Use the network namespace to configure two NICs separately, pay attention to replace veth0/veth1 with your NIC name ```shell ip netns add veth0spaces ip link set veth0 netns veth0spaces ip netns exec veth0spaces ifconfig veth0 192.168.1.100 netmask 255.255.255.0 up ip netns add veth1spaces ip link set veth1 netns veth1spaces ip netns exec veth1spaces ifconfig veth1 192.168.1.101 netmask 255.255.255.0 up ``` ## Example The following is an example of a ping packet test: ```shell ip netns exec veth0spaces ifconfig ip netns exec veth1spaces ifconfig ip netns exec veth1spaces ping 192.168.1.100 ip netns exec veth0spaces ping 192.168.1.101 ``` ## Uninstall ```shell make unload ``` delete network namespace ```shell ip netns del veth0spaces ip netns del veth1spaces ```
