For PHP developers, once a product is put into use, the display_errors option should be disabled immediately, this prevents hackers from attacking the paths, database connections, data tables, and other information exposed by these errors. However, when any product is put into use, it is difficult to avoid errors. how can we record some useful error reports for developers? We can use the error report as a log record in a separate text file. The error log record can help developers or administrat

Logs are very important for security. They record all kinds of events that occur in the system every day. You can use them to check the cause of the error or the traces left by the attacker when the system is attacked. The main functions of logs are audit and monitoring. It can also monitor the system status in real time, monitor and track intrusions, and so on. In Linux, there are three major log subsystems: Connection time log-the log is executed by multiple programs and written to/var/log/

Log System in Linux The log system records every status information of the system running in text, which helps us to observe the normal status of the system running and how to quickly locate the error location during system running errors; the following describes the log functions in Linux. Each operating system has its own powerful log function, which is available in windows, and also in linux; the log function in the linux operating system is mainly implemented through the service

For PHP developers, once a product is put into use, the display_errors option should be turned off immediately to avoid hackers being hacked by the path, database connection, data table, and other information that these errors reveal. However, when any product is put into use, there will inevitably be errors, so how to record some useful error reports to developers? We can use the error report as a log in a separate text file.Logging of error logs can help developers or managers see if there is

management methods in Linux system.1. The main log files consist of the following three types:> Kernel and System log: This log data is managed by the system service Syslog, which determines where the kernel messages and various system program messages are recorded, based on the settings in the master configuration file "/etc/syslog.conf". There are quite a few programs in the system that send their own log files to

For PHP developers, once a product has been put into use, the display_errors option should be turned off immediately to avoid hacking attacks for information such as the path, database connection, data sheet, etc. that were revealed by these errors. However, after any product is put into use, will inevitably have errors, then how to record some of the developers useful error reports? We can use error reporting as a log record in a separate text file. The record of the error log can help develop

kernel tools. These log files provide information for the security status of the system. We mainly explain two log daemons-syslog and klogd--and briefly describe other other log files that are generated by the Linux operating system. The goal is to provide basic configuration. 2.1 Syslog System Log Tool The Syslog tool is used in most Linux systems and is flexib

Because of the wide range of systems involved, it is impossible to clarify the logs of all UNIX-class systems, but most of them are similar. Below I will only use the common SunOS RedHat for introduction. for other systems, see related information. UNIX system log files are usually stored in the "/var/log and/var/adm" directory. Generally, you can view syslog. conf to check the log configuration, for example, CAT/etc/
