I. ARP protocol-Address Resolution ProtocolWhen communicating on the network, the source host's application knows the destination host's IP address and the port number, but does not know the destination host's hardware address, but the data packet first is receives by the network card to handle the upper layer protocol, if receives the data packet the hardware address does not match this machine, then discards directly. Therefore, the hardware address

DescriptionComputer room to do network transformation, need to replace the original internal and external network switch. The server is just the few cabinets that are replacing the switch. Replace the front room to ask us if we have to do mac binding. This binding mainly refers to the server has no static MAC address for the specified gateway. Because the switch is to be replaced, the LAN transfer data is transmitted through the Mac. If there is a binding, the server can not learn the new switch

By default, this option is enabled:

ARP attacks are common in LAN, and IP address conflicts may occur in attacked regions. If the gateway has already bound an IP address and a MAC address, it is easier to query, otherwise, it is indeed difficult to find a hacker to attack itself in a long LAN host.Generally, we use a firewall to find the attack culprit. ARP detect can be used to directly find attackers and possible targets. Next, let's take a

In the original BDC (Bussiness data catalog), you can define only one finder method for the object. In other words, if you need to obtain data from two views with different fields returned from a table, you actually need to create two completely different entities. In business connectivity services, you can now define multiple finder meth
The Finder fonts on the Mac system are too small, and the icons in the list view are too small to be able to browse the files, especially some pictures, only one by one. So how does the Mac change the Finder icon? How does mac change finder font size? Small weave here for everyone to introduce the method.
