wireshark port scan

The port is the current computer and outside the channel, so once the hacker locks the target computer, it will scan the computer is already open port, so as to get more useful information. Scan destination computer ports generally use Superscan, X-scan, and so on.First, the

First, TCP Commonly used port scanning methods are the following three: 1.connect scanning We know that the common TCP socket implementation process is The more essential connection and end process is the following: From the above two figures we can see that the target host of a port if the monitoring state (listening or linsten), then when I connect the target host can be successful, otherwise the

port is successful, it means that the port is open, otherwise it is closed.The most common feature of this technology is simplicity, and it does not require any permissions.The code is as follows:#include #include#pragmaComment (lib, "Ws2_32")#defineSTART 80//Start Port#defineEND 1024//terminating PortintMainintargcChar*argv[]) { inti; Wsadata ws; //WS used to

I have been working for half a year on part-time security. I would like to share with you how I am doing security here. of course, as a part-time employee, I am not very thorough and I am not a reference for attacking. The following describes port security, which is mainly used to enable ports for all ip segments in the IDC of the company. for example, for a server, only the ssh port is required by default.

A few days ago, I started to learn socket. I wrote a single-threaded single-host port scanner for one of the great help of yunshu. Today I want to change it to multi-host scanning, (The thread is still single and slow, but it can be used for learning. It doesn't matter if it is slow), but it won't be changed. Please give me some advice. /*Name: netxportCopyright: netxflyAuthor: netxflyDate: 12-10-04Description: A simple

In addition to reconnaissance IP, there is also one-port scan in the hacker's detection mode. "Port scans" allow you to know which services, ports are open and not used (which you can understand to find the channel to the computer) that is being scanned. 　　 first, port scanning Easy to find remote

I, TCP scan technology There are many common port scanning technologies, such as TCP connect () scanning, tcp syn scanning, and tcp fin scanning. There are also many articles on the network, such: the most basic scanning technology used by my program is described on the http://www.antai-genecon.com/suml/zhishiyy/jingong/duankougj.htm: TCP scanning.The CONNECT () System Call provided by the operating system

Here I will summarize it for my convenience. I.

IntroducedPython-nmap is a port scanning tool based on the system Nmap command, which is simple and convenient to use.Recently, in order to enhance server security and supervision, it is necessary to keep the company server open port scan records every day, once there is an increase in the decrease can be found.Previously wrote a https://github.com/bashhu/monitor

I. Overview Task Description: Develop a program to obtain a list of host IP addresses for the SNMP service on the LAN and write the corresponding files for use by other programs. Background knowledge: SNMP is UDP-based, and the standard SNMP service uses 161 and 162 ports. Ideas: 1, get the local area online host list; 2, get the SNMP port of each host (for example, 161) to open the State; 3. Write specific files in a specific format. Only the first t
