11.kali linux_基本工具-NETCAT(传输文件|目录、流媒体服务、端口扫描、远程克隆硬盘)

课时11 基本工具-NETCAT(传输文件/目录、流媒体服务、端口扫描、远程克隆硬盘)

NC—-传输文件/目录
传输文件
A: nc -lp 333 > 1.mp4
B: nc -nv 1.1.1.1. 333 < 1.mp4 – q 1

A: nc -q -lp 333 < a.mp4
B: nc -nv 1.1.1.1 333 > 2.mp4
传输目录
A: tar -cvf – music/ | nc -lp 333 – q 1
B: nc -nv 1.1.1.1 333 | tar -xvf –
加密传文件
A: nc -lp 333 | mcrypt –flush -Fbqd -a rijndael-256 -m ecb > 1.mp4          文件解密
B:  mcrypt –flush -Fbq -a rijndael-256 -m ecb < a.mp4 | nc -nv 1.1.1.1 333 -q 1     文件加密

A:
root:~/Desktop# nc -lp 333 | mcrypt –flush -Fbqd -a rijndael-256 -m ecb > 1.mp4
Enter passphrase: xxxx

B:
root:~/Desktop# mcrypt –flush -Fbq -a rijndael-256 -m ecb < a.mp4 | nc -nv 1.1.1.1 333 -q 1
Enter the passphrase (maximum of 512 characters)
Please use a combination of upper and lower case letters and numbers.
Enter passhrase: (UNKNOWN) [10.1.1.12] 333 (?) open
en

Enter passphrase: xxxx

NC不自带mcrypt,需要自己安装!

NC—–流媒体服务
A: cat 1.mp4 | nc -lp 333
B: nc -nv 1.1.1.1 333 | mplayer -vo x11 -cache 3000 –

NC—–端口扫描
nc -nvz 1.1.1.1 -65536
nc -vnzu 1.1.1.1 1-1024

root@1kali:~# nc -h
[v1.10-38]
connect to somewhere:   nc [-options] hostname port[s] [ports] …
listen for inbound: nc -l -p port [-options] [hostname] [port]
options:
-c shell commands   as `-e’; use /bin/sh to exec [dangerous!!]
-e filename     program to exec after connect [dangerous!!]
-b          allow broadcasts
-g gateway      source-routing hop point[s], up to 8                          设置路由器跃程通信网关,最高可设置8个。
-G num          source-routing pointer: 4, 8, 12, …                         设置来源路由指向器,其数值为4的倍数。
-h          this cruft
-i secs         delay interval for lines sent, ports sca                      延时的间隔
-k                      set keepalive option on socket
-l          listen mode, for inbound connects                             监听模式,入站连接
-n          numeric-only IP addresses, no DNS                             直接使用ip地址,而不用域名服务器
-o file         hex dump of traffic                                           指定文件名称,把往来传输的数据以16进制字码倾倒成该文件保存。
-p port         local port number                                             本地端口
-r          randomize local and remote ports                              随机本地和远程端口
-q secs         quit after EOF on stdin and delay of secs
-s addr         local source address
-T tos          set Type Of Service
-t          answer TELNET negotiation
-u          UDP mode                                                      udp  模式
-v          verbose [use twice to be more verbose]                        显示过程,vv 更多
-w secs         timeout for connects and final net reads                      等待连接超时
-z          zero-I/O mode [used for scanning]                             使用输入/输出模式,只在扫描通信端口时使用。

NC—–远程克隆硬盘
A: nc -lp 333 | dd of=/dev/sda
B: dd if=/dev/sda | nc -nv 1.1.1.1 333 -q 1

远程电子取证,可以讲目标服务器远程复制,或者内存。
