Kali Linux启动SSH服务安全套接层命令:

root@kali:~# service ssh start

root@kali:~# vim /etc/ssh/sshd_config

注:Vim热键指南:i键插入内容，ESC键退出编辑，"wq" 保存并退出，Shift+zz键返回当前终端桌面!

去掉哈希注释#，修改文件属性:

Port 22

Hostkey /etc/ssh/ssh_host_rsa_key

Hostkey /etc/ssh/ssh_host_ecdsa_key

Hoskey  /etc/ssh/ssh_host_ed25519_key

LoginGraceTime 0

PermitRootLogin prohibit-password

PermitRootLogin yes

PasswordAuthentication yes

TCPKeepAlive yes

ClientAliveInterval 60

root@kali:~# cat /etc/ssh/sshd_config

root@kali:~# cd /etc/ssh

root@kali:~# ls -l

查看当前SSH服务状态:

root@kali:~# service ssh restart

查看状态报错删除key:

sroot@kali:~# ervice ssh status

root@kali:~# ls -al ssh*key

root@kali:~# rm -rf  ssh*key

重新生成主机密钥:

root@kali:~# ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

root@kali:~# ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key

root@kali:~# ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key

重新开启ssh服务:

root@kali:~# service ssh restart

root@kali:~# service ssh status

查看防火墙状态:

root@kali:~# service iptables status

关闭防火墙:

root@kali:~# service iptables stop

root@kali:~# ssh root@ 192.168.0.104

系统自动启动SSH服务:

root@kali:~# update-rc.d ssh enable 

关闭系统自动启动SSH服务:

root@kali:~# update-rc.d ssh disabled

root@kali:~# ifconfig

注:Service服务器上安装Putty进行内网穿透回连本机IP!
