启用 SSH 服务

kali 2020.3 默认没有启用 SSH 服务：

$ systemctl status ssh
● ssh.service - OpenBSD Secure Shell server
     Loaded: loaded (/lib/systemd/system/ssh.service; disabled; vendor preset: disabled)
     Active: inactive (dead)
       Docs: man:sshd(8)
             man:sshd_config(5)

可以执行命令 systemctl start ssh 启用 SSH 服务，随后再执行命令 systemctl status ssh 查看服务是否成功启用：

$ systemctl start ssh
$ systemctl status ssh
● ssh.service - OpenBSD Secure Shell server
     Loaded: loaded (/lib/systemd/system/ssh.service; disabled; vendor preset: disabled)
     Active: active (running) since Sat 2020-08-22 09:55:16 EDT; 25s ago
       Docs: man:sshd(8)
             man:sshd_config(5)
    Process: 1174 ExecStartPre=/usr/sbin/sshd -t (code=exited, status=0/SUCCESS)
   Main PID: 1175 (sshd)
      Tasks: 1 (limit: 2310)
     Memory: 2.7M
     CGroup: /system.slice/ssh.service
             └─1175 sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups

执行命令 sudo systemctl enable ssh 可以设置 SSH 服务开机自启动：

$ sudo systemctl enable ssh 
[sudo] password for kali: 密码
Synchronizing state of ssh.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable ssh
Created symlink /etc/systemd/system/sshd.service → /lib/systemd/system/ssh.service.
Created symlink /etc/systemd/system/multi-user.target.wants/ssh.service → /lib/systemd/system/ssh.service.

如需允许超级用户登录，可以修改 /etc/ssh/sshd_config 配置文件，需将参数 PermitRootLogin 设为 yes，允许超级用户登录：

PermitRootLogin yes
