In a LAN or network-less environment, virtual machine sets the ip addresses of the network card VMnet1 and VMnet8, provided that a fixed ip address must be set-General Linux technology-Linux technology and application information. For more information, see the following. After VMware is installed, two virtual NICs are generated. VMnet1 and VMnet8, I have been usi

1. Enter the Router Settings page: http://192.168.1.12, find the "forwarding rules" option, my current router is tp-link, different models of Tp-link "forwarding rules" option location, settings are not the same, other routers are unknown.3, press to set up, enter the relevant information, click on the "new" button to add, after adding the "Service List" will display the record:4. Ensure that the Java Web project on the LAN computer that you want to a

Common threats at the data link layer include MAC address diffusion, DHCP server spoofing and address depletion, IP Address Spoofing and ARP attacks and spoofing. Next, let's take a look at the relevant principles and defense measures. I,MAC address Diffusion 1,Principle: MAC address diffusion uses the switch forwarding principle to attack hosts constantly using fake mac addresses for communication, so that the MAC address table of the switch overflows. When the switch receives normal data frame

Try the following methods:1. Check the network connection of this computer. Make sure that the computer can connect to the LAN.2. Check whether the computer is in the same working group as a network printer or a LAN computer.3. Check whether the Netbios settings are enabled.For detailed settings and interfaces, refer t

Prevent shared intrusion For example, in a LAN, the Server is equipped with a Win2000 Server System and NTFS partition. The client computers are Workl, Work2, and so on ...... WorkN, and has a Win98 or Win2000 Pro system. Assume that the user name of one of the clients is YD_xlpos and the password is Ei (9, which has been logged on to the domain, it can intrude into the server using the default sharing method: enter serveradmin $ in the address bar of

: At this point the first setup is complete. The second machine, but the IP address to be set as the following diagram, in order to let the two machine IP in the same network segment, LAN must condition. have been set up, almost succeeded more than half. The following is a copy of the machine to open the network, and then enable

To solve the problem of mutual access between different network segments in the LAN, you can enable Routing and Remote Access Services, take windows server 2003 as an example (server 2003 requires two NICs and their IP addresses are set to different IP segments. Let's take 192.168.1.1 and 192.168.2.1 as an example): 1. the default system settings for enabling Routing and Remote Access Services do not enable

Wired LAN: Ethernet classification Ethernet has gone through four generations of development: the minimum length of a standard Ethernet frame: 64 bytes. Maximum length: 1518 bytes. Addressing Ethernet uses a 6-byte physical address provided by the NIC, which is usually expressed in hexadecimal notation. For example: 06: 01: 02: 01: 2C: 4B Unicast address. The multicast address and broadcast address source address are always one Unicast address (becaus

Host system: win7 flagship Edition Virtual Machine: VMware Workstation 8.0 Server System: centos6.0 Network: Lan In the current situation, the centos and host servers can be pinged to each other. The network mode is bridging, but centos does not connect to the Internet. Solution (three steps ): 1. Add an IP address [Root @ localhost ~] # Vi/etc/sysconfig/

ARP spoofing:/* Normally the computer sends traffic to the gateway and deceives the traffic to the network card of this machine and forwards the machine to the gateway */--"First:Use FPING-ASG IP segment/* to scan a surviving host in a segment */--"Second:Turn on terminal input echo 1 >/proc/sys/net/ipv4/ip_forward for IP traffic forwarding--"Third:Input command: Arpspoof-i nic-t target host IP Gateway--"Four:Re-open a terminal input: Driftnet-i NIC/*
