渗透测试---系统扫描

xprobe2

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。但是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。

usage: xprobe2 [options] target
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.
