Linux port Scan Tool Nmap and Nwatch Introduction to Port scan The method of port scan port scan is a way to detect an opposing server service by detecting an open port on the other server. Generally can be divided into active and passive two kinds. An active type is to be judged by the answer by sending a packet to a

Basic ScanBefore I go into the detailed explanation, I will try a simple scan and have a basic understanding of nmap tools.1.1Scan OverviewNmap The main tools are host survival Scan, port scan, NSE. The scan is divided into a single target scan (by specifying a single IP add

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 closed. Advantages: Simple programming, is the need for an API connect (), more reliable,

Original: Sixth--optimize performance according to execution plan (2)--lookup table/Index ScanObjective:In most cases, table scans or index scans are not an efficient way to return small amounts of data, especially from a large table. These must be found and resolved to improve performance because the scan traverses each row, finds the qualifying data, and then returns the result. This processing is quite time consuming and resource-intensive. In the

Let's talk about MySQL's loose index scan, As we all know, InnoDB uses the index organization table (IOT), which is called the index organization table, and the leaf node stores all the data, which means that the data is always stored in a certain order. So the question is, what should be the execution of such a statement? The statement is as follows: select count(distinct a) from table1; If column a has an index, how can we

First, Shell queryHBase queries are fairly straightforward, providing both get and scan two ways, and there is no problem with multi-table federated queries. Complex queries need to create the appropriate external tables through hive, with SQL statements to automatically generate MapReduce.But this simple, sometimes to achieve the goal, is not so handy. At least it differs from SQL query in a large way.HBase provides a number of filters that can be fi

The AppScan window mode allows users to select only one scan target at a time, but if you want to scan multiple sites in bulkYou can do this by using the AppScanCMD.exe tool under the AppScan installation folder.(1) AppScan window mode allows only one target site to be selected for scanning(2) Go to the AppScan installation folder and look for the AppScanCMD.exe tool(3) CMD open appscancmd View Help documen

When we use SPRINGMVC, we know that SPRINGMVC can scan all the classes under the specified package, in the usual development, we also have such a scene, so today write a scan package of the tool class, the code is as follows: PackageCom.gujin.utils;ImportJava.io.File;ImportJava.io.FileFilter;ImportJava.io.IOException;ImportJava.net.JarURLConnection;ImportJava.net.URL;ImportJava.net.URLDecoder;ImportJava.uti

The method of scanning code login is more and more used by current application. Because it does not have to remember the password, as long as the number can be easily and quickly login. This is based on a public platform with the temporary QR Code, and combined with the Swoole WebSocket service to implement the scan code login. This article is mainly to share with you swoole implementation Scan Code login f

From: http://blogs.msdn.com/ B /apgcdsd/archive/2012/08/01/sql-server-scan-seek.aspx SQL SERVER uses scan and search algorithms to read data from data tables and indexes. These two algorithms constitute the foundation of queries, which are almost ubiquitous. Scan scans and returns the entire table or the entire index. Seek is more efficient. Based on the predicat

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. However, if other ports not permitted are enabled, it may be caused by false drive or int

The reason for the full table scan of the table's execution plan is as follows: No index is created for the u SQL predicate column. The u predicate column has a corresponding index, but the execution plan is not used. Oracle does not use B * tree indexes. 1: When the where condition is compared with null, the index may not be used. 2: When count, sum, ave, max, min and other aggregation operations are performed, the index may not be used. 3: No index
