　　 摘要

　　本程序用于收集，防火墙，路由器，交换机等日志

　　 下面是我多年积累下来的经验总结，整理成文档供大家参考:

　　 目录

1. 配置Cisco ASA 5550 Firewall

　　logging enable logging timestamp logging trap warnings logging host inside 172.16.0.5 logging facility local0

　　172.16.0.5 改为你的syslog服务器地址

2. syslog 服务器脚本

　　*注意：python版本必须3.0以上

　　chmod 700 syslogd

　　./syslogd
