Obtain the network interface device [Nic device] To capture network packets, you must first obtain the network interface device of your computer, which is also called the NIC device. the jpcap package provides us with this [static method]: jpcapcaptor. getdevicelist () is a list of Network Interface Devices, networkinterface class, and network interface class. It encapsulates the corresponding network port

However, when you configure the VM's IP address, you encounter a problem with the dual NIC configuration IP address.

After the virtual machine clone is started using Ifconfig, no IP address is found, only the loopback address is 127.0.0.1,The MAC address and host name are the same as the source host (the source host is manually configured IP).Any execution of the following commands is useless anyway:/etc/init.d/network restartIfup eth0Workaround:1. Edit the eth0 configuration file: Vi/etc/sysconfig/network-scripts/ifcfg-eth0, delete the hwaddr address the line and UUID lines are as follows:hwaddr=00:0c:29:2c:6

Recently, using Exsi to quickly deploy Linux, the cloned Linux system network was found to be unhealthy during the operation.The original machine has two network cards, eth0 and eth1, cloning, cloning machine network can not start,For example, an exception would be thrown: Bringing up interface Eth0:pcnet32 device eth0 does not seepresent, delaying initialization.With IFCONFIG-A does not exist eth0, more eth2,eth3, into/etc/sysconfig/network-scripts/found only eth0, and eth1 where

1. Get IP address automaticallyVirtual machines use bridging mode, which is equivalent to a network connected to a physical machine, and the physical machine network has a DHCP server that automatically assigns IP addresses.#dhclient Auto Get IP address command#ifconfig Query System network card information, IP address, MAC addressAfter assigning to an IP address, ping the IP address with the physical machine and detect if it is ping.2. Manually set the IP addressIf the virtual machine does not

Today in the practice of a sudden thought if the current use of the virtual machine in the system is broken or an unknown failure to affect the learning progress what to do, after all, re-install a system to delay a lot of time, so want to use the current normal system copy a backupAfter copy, use VMware to open and change the name, boot OK, login OK, test network faile ...
