arp ping scan

without firewalls and packet filtering software to isolate Nmap's probing scans.MAC address is: 00:1a:a9:15:49:07 (this information is very useful, later we can use ARP attack)The time taken for the scan is: 20.39 secondsAt this point, you can determine that the installation was successful.4, improve the performance of the connection scan(1) Enter the installati

Today, there is a POS device to the Internet, do not know his MAC address, can not allocate IP, only binding IP to the Internet. First give a random set of IP. With a ping command, comment, the device is pass. Then use ARP-A to view the MAC address of the ARP list. method is very practical. The special note. Generally do not think of it. Oh 1.

the address type to be converted, and 0x0800 is the IP address, the length of the following two addresses is 6 and 4 (bytes) for the ethernet address and IP address respectively. The op field is 1, indicating the ARP request, and the OP field is 2, indicating the ARP response. The process of the Address Resolution Protocol is as follows: Iv. RARP (Reverse Address Resolution Protocol) The opposite of

Linux systems use Arp-scan to check for IP address conflictsIf the IP address planning is not good, even if there is a unified IP address will make mistakes! Recommended server IP address use to register details, the last computer room batch deployment server, will have been reused IP and assigned to another server, fortunately, the business has not caused great impact.So when configuring IP for the server,
