用indexmaker -o  /home/httpd/mrtg/103/index.html  /home/httpd/mrtg/103/mrtg.cfg  生成网页，在crontab 中加入*/5 * * * * mrtg /home/httpd/mrtg/103/mrtg.cfg   
OK，这样我们就能通过mrtg生成的图来监控我们linux的机器的状态了。在IE中打入http://192.168.13.105/mrtg/103,mrtg的监控网页就出来啦（/home/httpd/是我appache的主目录）。当然我们也能用snmpwalk命令来得到安装有snmp服务的win2000机器的状态的数据：

上面显示的是192.168.1.5这台win2000SERVER的磁盘信息，可以看到盘符、每个分区的空间总量、使用量等。其它的相应建值还有：

netcard physcal address:                IF-MIB::ifPhysAddress 
这样我们就可以用一台linux主机通过snmp+mrtg来监控多台局域网内的linux/win2000SERVER了：）。 
现在我最关心的是如何让snmp包穿过防火墙，（我用snmpwalk试了一下，抓不到公司在IDC防火墙后的SERVER的snmp数据）。不然，我就可以用snmp去监控公司在IDC防火墙后的SERVER的状态了。听说perl能实现，但不知用什么样的方法来实现？
