Protostar，linux 无法解析 'ftp.au.debian.org'

Question

我想在 https://exploit-exercises.lains.space/

中进行 Protostar 漏洞利用练习

我想安装 Python 3 版本，为此我需要运行 sudo apt-get update 命令。但它似乎失败了，问题出在 dns 上。但不幸的是我无法修复它。

这是我运行命令时的输出。

如何将其修复为运行 sudo apt-get update ？

Answer 1

所以要解决并在 Protostar 上下载 python 3.6 :

（显然由于 virtualbox 中的 Host-only 适配器，主机上没有互联网连接）

使用 wget 下载 python：

wget https://www.python.org/ftp/python/3.6.9/Python-3.6.9.tgz

然后我使用 scp ( ssh ) 传输它（你可以将它移动到 /tmp 然后再到 /usr/sbin 如果它说没有权限）

scp Python-3.6.9.tgz root@192.168.56.102:/usr/sbin

导出并安装 python

 tar xvf Python-3.6.9.tgzls
 ./configure
 sudo make install

最后：

alias python=/usr/sbin/Python-3.6.9/python
