For different types of UNIX, standard unixlog system settings, except for some different keywords, the system's syslog. conf 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 according to/etc/

BKJIA exclusive report: syslog has been adopted by many log functions and is used in many protection measures. Any program can use syslog to record events. Syslog can record system events, write to a file or device, or send a message to users. It can record local events or events on another host over the network.

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
This experiment is to configure a general router as a frame relay switch to provide a frame relay experimental environment for other experiments in this chapter.1. Tutorial PurposeThrough this experiment, you can master the following skills:● Configure a frame relay environment with only two nodes;● Configure a star frame rel
In small and medium enterprise network interconnection, there are many connections using Frame Relay networks because the transmission mode is similar to a leased line and supports Traffic Transmission. If it is a frame relay network, then, the interfaces connecting the vswitch are all various frame relay nodes. In this way, multiple virtual connection channels a

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
equipment log records summary, easy to manage and query, extract useful log information for network security management use, timely found about security equipment in the process of security problems, In order to better ensure the network uptime.

A syslog server represents a central log monitoring point in a network, to which all kinds of devices including Linux or W indows servers, routers, switches or any other hosts can send their logs over network. By setting-a syslog server, you can filter and consolidate logs from different hosts and devices to a single location , so the can view and archive important log messages more easily. In this tutorial
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
