1. foreword syslog is a log record method (rfc00004) provided in Unix systems. syslog itself is a server. All information recorded using syslog in the program will be sent to this server, the server determines whether to record the information based on the configuration, whether to record the information to the disk file or other places, so that all applications
Syslog is the default log daemon in a Linux system, and the default syslog configuration file is the/etc/syslog.conf file. The program, daemon, and kernel provide log information for accessing the system. Any program that wants to generate log information can generate this information to a syslog interface call.Almost all network devices can transmit the log info

For different types of UNIX, standard unixlog system settings, except for some different keywordsSyslog. confThe format is the same. Syslog uses a configurable and unified system registration program to receive log requests from all over the system at any time, and then acco
With the rapid development of information technology, more and more devices in the network, and gradually we found that relying on traditional means to a table analysis equipment (routers, switches, firewalls, servers, databases, middleware, etc.) logs have seriously affected our work efficiency, and not the availability of business systems to provide protection. Always play the role of a fireman after a problem arises. Therefore, it is time for the operation of the log to centrally manage.
Key
We know that both Unix, Linux, FreeBSD, Ubuntu, routers, switches, and so on, generate a lot of logs, which are typically in the form of syslog. Debugging a firewall, intrusion detection, security audit and other products, friends should be familiar with the syslog, if you do not know the syslog, please login Baidu or Google query.
Many times, we need to central

For large-scale network applications or applications with certain security requirements, you usually need to classify and review system logs. By default, each system records its own logs on the local hard disk.
Although logs can also be recorded, there are many disadvantages: first, management is inconvenient. When the number of servers is large, it is very inconvenient to log on to each server to manage and analyze

The syslog mechanism is responsible for sending and recording the information generated by the system kernel and tools. it consists of the syslog () call, the syslogd daemon process, and the configuration file/etc/syslog. conf.
