Recently because of the examination of various review by the way to brush TV, feel with the small partners playing more and more unhappy, must have been too busy recently, uh. So want to study the proxy server, download a code, found unexpectedly also involves socket programming, so the network class before the socket Chat room small lesson set out to tidy up ideas.Code reference: http://www.oschina.net/code/snippet_1387924_25928Paste the code First:#Coding:utf-8ImportSocketImportSYSImportThread
information we care about. Different EVENT IDs represent different meanings, which can be easily found online, here are some of the things we usually use.
With this, we can analyze windows logs. For example, when we analyze domain control logs, we want to query the information about the user's correct account and wrong password during account logon, when we need to calculate the source IP address, time, and user name, we can write this (of course, we can also combine some statistical functions
(Strings, 2, '| ') as service \ _ NAME, EXTRACT \ _ TOKEN (Strings, 5, '|') AS Client_IP FROM 'e: \ logparser \ xx. evtx 'where EventID = 675"
The query result is as follows:
To collect statistics on specific IP addresses, we can write this statement (NAT output by default ):
LogParser.exe-I: EVT "SELECT TimeGenerated, EXTRACT \ _ TOKEN (Strings, 0, '|') AS USERNAME, EXTRACT \ _ TOKEN (Strings, 2, '| ') as service \ _ NAME, EXTRACT \ _ TOKEN (Stri

design documents, Application Scenario descriptions, and openSource codeHands-on labs, Getting Started guides, help documents, and other layers provide overall guidance to the development team, at present, three of the software factories have been implemented and achieved good results in some major projects at home and abroad. This model and practice series of network broadcast will introduce and analyze these three most mature software factories to provide reference for the actual product and

Typically, people use file-based logs. There is no problem with this, but it is easier to use Windows to provide system internal logs.
If you have administrative privileges, you can create a new log at any time:
Copy Code code as follows:
New-eventlog-logname Mylog-source Jobdue, Jobdone, remark
This command creates a log called MyLog, which originates from "Jobdue", "Jobdone" and "remark". Admin permissions are just to create the log, the rest of the operation can be operated

using a custom mapred script
Caveats: When using a custom mapred script, the keyword map REDUCE is the statement select TRANSFORM (...) Syntax conversion does not mean that a new map process is forced when using the Map keyword, and a red process is generated when using the Reduce keyword.
A custom mapred script can be a more complex function of the HQL statement, but performance is a bit worse than the HQL statement, and should be avoided as much as possible, using the UDTF function to replace
