Xprobe2：主动操作系统指纹工具

XProbe是一款远程主机操作系统探查工具。开发者基于和Nmap相同的一些技术（same techniques），并加入了自己的创新。Xprobe通过ICMP协议来获得指纹。最新版本是Xprobe2.0.3版本,Xprobe2通过模糊矩阵统计分析主动探测数据报对应的ICMP数据报特征,进而探测得到远端操作系统的类型。注:经过本人测试,对比较老的操作系统,识别效果非常高,对新内核系统则识别效果不太准确。

安装步骤：

#tar -zxvf  xprobe2-0.3.tar.gz
#./configure --prefix=/usr/loca/
# make
#make install

 用法:

#/usr/local/xprobe/bin/xprobe2 -h
Options:
          -v                       Be verbose
          -r                       Show route to target(traceroute)
          -p Specify portnumber, protocol and state.
                                   Example: tcp:23:open, UDP:53:CLOSED
          -c           Specify config file to use.
          -h                       Print this help.
          -o                Use logfile to log everything.
          -t             Set initial receive timeout or roundtrip time.
          -s           Set packsending delay (milseconds).
          -d              Specify debugging level.
          -D               Disable module number .
          -M               Enable module number .
          -L                       Display modules.
          -m         Specify number of matches to print.
          -T             Enable TCP portscan for specified port(s).
                                   Example: -T21-23,53,110
          -U             Enable UDP portscan for specified port(s).
          -f                       force fixed round-trip time (-t opt).
          -F                       Generate signature (use -o to save to a file).
          -X                       Generate XML output and save it to logfile specified with -o.
          -B                       Options forces TCP handshake module to try to guess open TCP port
          -A                       Perform analysis of sample packets gathered during portscan in
                                   order to detect suspicious traffic (i.e. transparent proxies,
                                   firewalls/NIDSs resetting connections). Use with -T.
 

以上个选项,读者可自己去测试。本人给出一个简单的测试，假设当前目录在/usr/local/xprobe/bin/下

探测出上海(本人测试地点IP)这边访问网易的系统IP为220.181.28.51的机器系统为linux系统 ,并且内核版本在2.6.1---2.6.11之间,也有可能是更高内核版本,主要是xprobe目前支持探测系统指纹的系统版本有限,经过我多次对不同系统freebsd,debian,centos,solaris,aix,windows xp,2000,2003的探测结果,发现越老的系统探测结果越准确,笔者支持该软件作者继续此工作!
