see the SSID? This is because the AP has enabled the Broadcast SSID option when setting it to facilitate User connection. If a hacker wants to steal confidential data by placing an illegal Rogue AP in the network, I believe it will not be silly enough to open the broadcast and tell the Administrator that there is an AP in your network with "excellent signal quality", right? We can boldly assume that all the SSID we don't know may be illegal, and any hidden SSID we don't see will be illegal! May

drinks coffee and uses his laptop to log on to the Internet. The salesperson uses the company's credit card to pay for his network access, and then uses his username and password to connect to the company's network. He accesses the customer's files, and log on to his bank network to check the balance of his bank deposits, and then cancel and leave the coffee shop. A salesperson connects to a hacker's simulated hotspot "network", so that a malicious hacker can obtain a large amount of informatio

). First, recursively analyze the Expr in the group by clause, and if having clause is like the where clause, it is first a tree composed of Expr in analyze having clause, and then to Analyzer registerConjunct. (6) process InlineView. The data structures involved in SQL parsing are as follows: At this point, the lexical analysis ends, a bit like a small compiler. Now we are going back to the frontend. createExecRequest () function. After AnalysisContext. analyze () is called, the member variab

First, the use of explain: PostgreSQL generates a query plan for each query because the performance impact of selecting the correct query path is critical. PostgreSQL itself already contains a planner for finding the optimal plan, and we can view the query plan generated by the planner for each query by using the explain command.The query plan generated in PostgreSQL is a planning tree consisting of 1 to n

the-B Option to specify the multi-point Transfer Group IP address to start multiple iPerf servers. Then open your iPerf client and connect to the previously started multicast group iPerf server. Use the test tool iPerf to monitor wireless network performance: Graphical Test Result As described in this article, the iPerf program can be run in the command line, or in a Java implementation front-end tool named JPerf. JPerf not only simplifies the construction of complex command line parameters, b

manufacturers also in the relevant driver software to increase the wireless scanning function. The dual-mode card provided by Proxim can simultaneously scan all appropriate channels within the 802.11a and 802.11b bands and visually display signal strength and bandwidth. The perfect Wi-Fi protocol analyzer is much more powerful than NetStumbler or Nic-driven software, and the implementation is very different. Some protocol parsers can decode advanced protocols, includes a complete TCP/IP stack

Travel Plan application (Wayfindit:trip Planner app) In most cases, wayfindit applications must be well accessible. Travel is a complicated business, whether it's a commercial trip or a vacation trip, and a smooth journey requires no surprises from home to destination. The application of Wayfindit can provide the traveler with the required information and be quick and accurate. This means that it requires a minimal, intuitive, responsive interface th

a significant role. For example, AirMagnet survey not only uses Iperf to measure uplink and downlink performance, but it can also be used to analyze 802.11n recommended settings and quick voice evaluations. Veriwave Wavedeploy is an agent-based site assessment tool that generates test streams that, when sent to real-world client devices, not only measure TCP throughput, but also measure the "quality of experience" of web, voice, and video. By testin

troubles. WLAN upgrade is an opportunity to deploy NAC in a simple and isolated location, and helps customers experience better wireless access extension experience when experiencing the benefits of NAC. Wireless intrusion detection and defense The customer wants to detect rogue APs, such as WPA2, which can be embedded into the WLAN infrastructure. To avoid risks, especially in the retail, medical, insurance, and financial services industries, customers may find that rogue scanning does not eff

each event. Then, it calls an appropriate activity object to process the event. When an activity object processes an event and the event processing function returns to the activity scheduler, the object cannot be preemptible, That is to say, Runl () An event handler is an atomic operation.In Symbian OS, the active objects collaborate with each other to implement multiple tasks in sequence, and do not need to protect shared resources synchronously. In addition, because the active objects run in

loaded, inspected, transformed, and so on before the table becomes partitioned.CREATE TABLE measurement_y2008m02 (like measurement including DEFAULTS including CONSTRAINTS); ALTER TABLE measurement_y2008m02 ADD CONSTRAINT y2008m02 CHECK (logdate >= date ' 2008-02-01 ' and Logdate 4. Partitioning and constraint exclusionsconstraint exclusion is a query optimization technique that improves the performance of table partitioning defined by the above method. Like what:SET constraint_exclusion =

category of self-help groups: 1. Self-driving tour. This kind of crowd mainly by the white-collar workers and managers in the city, in the weekend they generally choose to travel around the city, the traffic mode to their own cars or car rental mainly, a few friends and relatives to find a mountain with water to eat, live, play, the purpose is to change the environment, change mood. This kind of people use hot Belt Travel Network Travel planner, the

I. Type of index: PostgreSQL provides a variety of index types: b-tree, Hash, Gist, and gin, because they use different algorithms, so each index type has its appropriate query type, and by default the CREATE INDEX command creates a B-tree index.1. B-tree: Copy Code code as follows: CREATE TABLE Test1 ( ID Integer, Content varchar ); CREATE INDEX Test1_id_index on test1 (ID); The B-tree index is used primarily for equals and range queries, especially when the index

Query optimization for distributed Database Systems Calcite is a set of open source query engine, many open source projects use the open source project, especially the use of its optimizer part, similar to drill, Hive, flink use calcite as its optimization engine.Calcite realized that two sets of Planner,hepplanner and Volcanoplanner,hepplanner are mainly a kind of greedy planner, and volcano is a kind of h
