它适用于 ubuntu 图像

wolf@linux:~$ docker run -it ubuntu /bin/bash
root@00e6296d31d8:/#

但是，当我尝试使用不同的图像（例如 ）时vulnerables/web-dvwa，它不再起作用

wolf@linux:~$ docker run -it vulnerables/web-dvwa /bin/bash

此容器中没有 bash shell

wolf@linux:~$ docker ps

这是我在主机操作系统中使用的命令，不幸的是客户操作系统仍然无法获取 DHCP ip。

两个操作系统都在 Linux 中运行。

wolf@linux:~$ vboxmanage dhcpserver add --network=malfoy --server-ip=10.38.1.1 --lower-ip=10.38.1.110 --upper-ip=10.38.1.120 --netmask=255.255.255.0 --enable
wolf@linux:~$

确认

wolf@linux:~$ vboxmanage list dhcpservers
NetworkName:    malfoy
Dhcpd IP:       10.38.1.1
LowerIPAddress: 10.38.1.110
UpperIPAddress: 10.38.1.120
NetworkMask:    255.255.255.0
Enabled:        Yes
Global Configuration:
    minLeaseTime:     default
    defaultLeaseTime: default
    maxLeaseTime:     default
    Forced options:   None
    Suppressed opts.: None
        1/legacy: 255.255.255.0
Groups:               None
Individual Configs:   None

我刚刚在 Ubuntu 20.04 上安装了 docker，并注意到 docker 必须作为 sudo 运行。

wolf@linux:~$ docker ps
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: dial unix /var/run/docker.sock: connect: permission denied
wolf@linux:~$ 

wolf@linux:~$ sudo docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
wolf@linux:~$

找到本教程并尝试遵循它

第 2 步 — 在不使用 Sudo 的情况下执行 Docker 命令（可选）

https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-20-04

wolf@linux:~$ sudo usermod -aG docker ${USER}
wolf@linux:~$ su - ${USER}
Password: 
wolf@linux:~$

这里似乎还不错。

wolf@linux:~$ id -nG
wolf docker
wolf@linux:~$ 

wolf@linux:~$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
wolf@linux:~$

但是，当我打开另一个终端时，它不再工作了。我收到与上述类似的错误。

我注意到nmap -sn不再提供远程主机的 MAC 地址，如我可以使用 nmap 发现 IP 和 MAC 地址吗？

我想得到类似netdiscover输出的东西。仅 IP 和 MAC 地址。

Nmap 7.80 版

wolf@linux:~$ nmap -V
Nmap version 7.80 ( https://nmap.org )
Platform: x86_64-pc-linux-gnu

例如

wolf@linux:~$ nmap -sn -oG - 10.10.10.*
# Nmap 7.80 scan initiated Wed May 20 12:38:57 2020 as: nmap -sn -oG - 10.10.10.*
Host: 10.10.10.1 () Status: Up
Host: 10.10.10.2 () Status: Up
Host: 10.10.10.3 () Status: Up
# Nmap done at Wed May 20 12:38:59 2020 -- 256 IP addresses (3 hosts up) scanned in 2.25 seconds
wolf@linux:~$
