Firewall Log Daemon是一个用C编写的程序，它实时监视IP链或IP表日志警告。程序将启动一个小型后台监控进程，通过读取由系统日志写的FIFO来分析和解决防火墙日志。它可以查询一批警告，并将它们用邮件发送给你，或是由一个脚本用来处理现存的日志文件或数据流。它的功能有主机名，端口，协议，和ICMP类型/代码检查，可以由用户定义模板来格式化输出-Firewall Log daemon is a C preparation procedures, which real-time monitoring of IP or IP chain warned log table. Procedures will launch a small background monitoring process through the system log read from the FIFO write to analyze and solve firewall log. It can find a number of warnings, and use them to send mail to you, or from a script to handle the existing log file or data stream. It is the function of host name, port, protocol, and ICMP type/code inspection, by the user-defined templates to format output
