本地是adsl,只有一台机子， 不是192.168.1.15，而且登录adsl的web管理界面后，查看记录里面有两个网卡地址是陌生的。很奇怪。。

原来本机地址是192.168.1.200 ／adsl猫 是192.168.1.1\r\nPing192.168.1.15 能够ping通,但不知道那是个什么东东，也不知道从哪里来，nmap -O 192.168.1.15识别显示是(realtek semiconductor)这么奇怪的东东到底是什么。\r\n感觉不对劲以后我把地址改为192.168.2.200 ／adsl猫是192.168.2.1\r\nping 192.168.1.15后就出现了顶楼的效果。
