Cracking Network Passwords (Hydra)NetSec

建立一個 router 和 Linux，並將它們設置 IP

R1

int e0/0

ip addr 192.168.1.1 255.255.255.0

no shut

line vty 0 4

login

password cisco

transport input telnet

Linux

ip addr add 192.168.1.2/24 brd + dev eth0

ping 192.168.1.1

telnet 192.168.1.1

Linux

eth0 自帶 IP，可以直接 Ping8.8.8.8和www.google.com

時間設置

timedatectl set-timezone Asia/Taipei

更新

systemctl restart ntp.service

ntpd

apt update

apt install curl wget

useradd user

mkdir /home/user -p

chown user:user /home/user

su - user

bash

git clone https://github.com/reverse-shell/routersploit

cd routersploit/

python3 -m pip install -r requirements.txt

python3 rsf.py

use scanners/routers/router_scan

set target 12.1.1.1

run

exit
