Nmap的使用问题！ 急 在线等答案

Starting Nmap 4.76 ( http://nmap.org ) at 2009-09-20 04:36 中国标准时间 pcap_open_live(ppp0, 100, 0, 2) FAILED. Reported error: Error opening adapter: 系统找不到指定的设备。 (20). Will wait 5 seconds then retry. pcap_open_live(ppp0, 100, 0, 2) FAILED. Reported error: Error opening adapter: 系统找不到指定的设备。 (20). Will wait 25 seconds then retry. Call to pcap_open_live(ppp0, 100, 0, 2) failed three times. Reported error: Erro r opening adapter: 系统找不到指定的设备。 (20) There are several possible reasons for this, depending on your operating system: LINUX: If you are getting Socket type not supported, try modprobe af_packet or r ecompile your kernel with SOCK_PACKET enabled. *BSD: If you are getting device not configured, you need to recompile your kern el with Berkeley Packet Filter support. If you are getting No such file or dire ctory, try creating the device (eg cd /dev; MAKEDEV <device>; or use mknod). *WINDOWS: Nmap only supports ethernet interfaces on Windows for most operations because Microsoft disabled raw sockets as of Windows XP SP2. Depending on the reason for this error, it is possible that the --unprivileged command-line argum ent will help. SOLARIS: If you are trying to scan localhost and getting '/dev/lo0: No such fil e or directory', complain to Sun. I don't think Solaris can support advanced lo calhost scans. You can probably use "-PN -sT localhost" though.

首先你的系统是否是xp，而且为ppp0拨号上网？如果是，那就无法用nmap扫描外网，不过可以扫描本地局域网。解决的办法就是换个上网方式，或用代理看看。 还有就是换个windows server 2003看看，都不行就安装个虚拟机，虚拟机跟主机通过nat上网，在虚拟机里可以用nmap扫描外网了，虚拟机可以是xp系统。
