首先--前言

下载终端预览软件，颜值高，在 Microsoft store里下载就行了，所幸软件大小是可以接受范围，因为会默认装在 C 盘内，按网上更改下一次软件安装地点在我的电脑上是无效的，所以我没有在 Microsoft store 下载子系统，微软提供了手动下载子系统包的方法，旧版 WSL 的手动安装步骤 | Microsoft Docs，在上面直接下载.appx文件即可，下载完以后放到自己想放的文件夹，然后修改后缀名为.zip，解压缩以后点击对应的ubuntu.exe即可。

这里点一下最基本的报错：权限不足：Permission denied，使用sudo或chmod赋予权限即可

重复配置易遇到的问题

两个问题，一样的解决方法！！！！

显示xxxx报错，然后输入一个键退出了，好像有啥错误代码，代码是一串地址，后门是几个问号。

ubuntu.exe 打开闪退

利用wsl --list --verbose查看当前电脑上子系统信息
然后看到一个或多个 running 状态的 wsl（表示配置好了）
运行wsl --unregister Ubuntu-16.04，这里更改成上面查到的相应版本的 NAME 即可，将其注销，然后再运行 Ubuntu16.04.exe 进行安装即可
成功之后打开终端预览，找到 ubuntu 进行注册。

参考大佬博客进行配置

我这里使用的是看雪大佬的博客，写的非常好，基本都可以配置成功[原创]CTF_Pwn环境搭建-Pwn-看雪论坛-安全社区|安全招聘|bbs.pediy.com，但有点小问题下面会进行说明：

ubuntu18.04 的基础配置：

python3：3.6.7

vim

git

安装 python2，直接输入python2即可，系统会自动给出代码：

sudo apt install python-minimal

这里出现了一个问题，是由于DNS未配置以及软件源配置导致的下载进度贼慢以及易出错

遇到含有：Temporary failure resolving 'archive.ubuntu.com 之类的

#打开配置文件
sudo vim /etc/resolv.conf
#添加相关解析
nameserver 114.114.114.114
nameserver 8.8.8.8
#关掉重启复原，不关掉下次重启又变成默认了，在这上面吃了好几次苦头了
sudo vim /etc/wsl.conf:    #打开
[network]                  #添加
generateResolvConf = false
#后来发现上面的没啥用，找到了这样一条回答
编辑 /etc/systemd/resolved.conf 这个文件，把 DNS 那一行解开注释
#我也不知道上面有没有用，后来我还把文件全删掉重新建立赋予777权限试了一下。

ubuntu18.04 更改设置镜像源

#先备份原来的源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
#然后修改源
sudo vim /etc/apt/sources.list
#按d进行删除，再粘贴下列源地址：

#更新一下
sudo apt-get update
sudo apt-get upgrade

在更新的时候容易出现报错

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

直接删掉就行了

sudo rm /var/lib/dpkg/lock-frontend

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

再删

sudo rm /var/lib/dpkg/lock

The following packages were automatically installed and are no longer required:
libdumbnet1 libfreetype6
Use 'sudo apt autoremove' to remove them.
E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/cache/apt/archives/

按照它的提示操作 

sudo apt autoremove

E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/cache/apt/archives/

不要慌，胜利就在前方，继续删除

sudo rm /var/cache/apt/archives/lock

然后就可以正常进行更新了，5分钟作用就可以更新保存完毕了，再进行基础配件的安装。

安装pip

#更新软件包列表
sudo apt update
#为python2及其依赖安装pip
sudo apt install python-pip
#查询版本
pip --version
#为Python 3安装pip
sudo apt install python3-pip

继续安装 python

直接使用它给出来的三个命令

sudo apt install python3
sudo apt install python
sudo apt install python-minimal

这里很多人用不习惯 python2的话，可以进一步配置：

！！！！！！注意！！！千万不要将系统自带的python3.6环境卸载，否则将面临很大的隐患，可能得像我一样重新装系统。！！！！！！

#添加PPA(Personal Package Archive 个人包档案)
sudo add-apt-repository ppa:jonathonf/python-3.8

#检查apt-get更新，通过软链命令安装Python3.8
sudo apt-get update
sudo apt-get install python3.8

#更换系统默认的软链命令
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 2

#Python版本的切换
sudo update-alternatives --config python3

#升级好Python版本后，需要升级pip命令版本，否则安装时也还会报错
python3 -m pip install --upgrade pip
==>Successfully installed pip-22.1

接下来是设置python软链接

#查看当前系统默认python版本
python --version
#查看python3
whereis python3
#删除原有python2的软连接
sudo rm /usr/bin/python
#新建python3的软连接
sudo ln -s /usr/bin/python3.8 /usr/bin/python
#重新查看默认的python版本
python --version

安装pwntools

博客上是python2版本的，我们使用python3，直接上pwntools文档上查看下下载方式：

apt-get update
apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade pwntools

在更新的时候又报错了

Traceback (most recent call last):
File "/usr/lib/cnf-update-db", line 8, in
from CommandNotFound.db.creator import DbCreator
File "/usr/lib/python3/dist-packages/CommandNotFound/db/creator.py", line 11, in
import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/lib/command-not-found/ -a -e /usr/lib/cnf-update-db; then /usr/lib/cnf-update-db > /dev/null; fi'
E: Sub-process returned an error code

解决方法：

# 创建一个软链接
cd /usr/lib/python3/dist-packages
sudo ln -s apt_pkg.cpython-36m-x86_64-linux-gnu.so apt_pkg.so

切换了国内源的话速度会非常快！！

安装pwntools最后一步又报错了

distutils.errors.DistutilsExecError: command 'x86_64-linux-gnu-gcc' failed with exit status 1

大概是因为模块对系统库的依赖有问题，可以执行以下命令更新：

sudo apt-get update
sudo apt-get install libffi-dev g++ libssl-dev

然后：

The following packages were automatically installed and are no longer required:
libdumbnet1 libfreetype6
Use 'sudo apt autoremove' to remove them.

sudo apt autoremove

然而并没有什么用，重新安装pwntools的时候还是报错了，网上说是依赖没有装全，再装一下试试：

sudo apt-get install build-essential python3-dev libssl-dev libffi-dev libxml2 libxml2-dev libxslt1-dev zlib1g-dev

然后进行安装就成功了，虽然有WARNING，但是这个东西约等于没错。

检验是否安装成功

打开 python，输入from pwn import *看看是否有报错即可。

gdb

gdb安装

直接输入gdb看看有没有安装，发现没有并给出了安装命令

sudo apt install gdb

再次gdb试试，发现成功！

peda/pwngdb/gef

这是常见的gdb的三个插件，配合gdb使用可以提升调试效率。

pwndbg

git clone https://github.com/pwndbg/pwndbg
cd pwndbg
./setup.sh

peda

git clone https://github.com/longld/peda.git ~/peda
echo "source ~/peda/peda.py" >> ~/.gdbinit
echo "DONE! debug your program with gdb and enjoy"

gef

方法一：
wget -q -O- https://github.com/hugsy/gef/raw/master/gef.sh | sh
方法二：
wget -q -O ~/.gdbinit-gef.py https://github.com/hugsy/gef/raw/master/gef.py
echo source ~/.gdbinit-gef.py >> ~/.gdbinit
备用方法：
wget -q -O "$HOME/.gdbinit-gef.py" https://github.com/hugsy/gef/raw/master/gef.py
test -f "$HOME/.gdbinit" && mv "$HOME/.gdbinit" "$HOME/.gdbinit.old"
echo "source $HOME/.gdbinit-gef.py" > "$HOME/.gdbinit"

因为在同一时刻只能使用一种插件，而且在解决不同类型的题目时使用不同的插件，因此需要配置三种插件的快捷切换。aptx4869_li师傅给出了一款 GDB 控制插件，在这之前注释掉.gdbinit文件：

vim ~/.gdbinit
#把原本的 source 注释掉，现在的状态是没有选择插件。
#加一个可以识别的字符串，随便啥都行，做个标志而已
# this place is controled by user's shell

下面就是控制脚本：

#!/bin/bash
function Mode_change {
    name=$1
    gdbinitfile=~/.gdbinit    #这个路径按照你的实际情况修改
    # gdbinitfile=/root/Desktop/mode

    peda="source ~/peda/peda.py"   #这个路径按照你的实际情况修改
    gef="source ~/.gdbinit-gef.py"   #这个路径按照你的实际情况修改
    pwndbg="source ~/pwndbg/gdbinit.py"   #这个路径按照你的实际情况修改

    sign=$(cat $gdbinitfile | grep -n "#this place is controled by user's shell")     
           #此处上面的查找内容要和你自己的保持一致

    pattern=":#this place is controled by user's shell"
    number=${sign%$pattern}
    location=$[number+2]

    parameter_add=${location}i
    parameter_del=${location}d

    message="TEST"

    if [ $name -eq "1" ];then
        sed -i "$parameter_del" $gdbinitfile
        sed -i "$parameter_add $peda" $gdbinitfile
        echo -e "Please enjoy the peda!\n"
    elif [ $name -eq "2" ];then
        sed -i "$parameter_del" $gdbinitfile
        sed -i "$parameter_add $gef" $gdbinitfile
        echo -e "Please enjoy the gef!\n"
    elif [ $name -eq "3" ];then
        sed -i "$parameter_del" $gdbinitfile
        sed -i "$parameter_add $pwndbg" $gdbinitfile
        echo -e "Please enjoy the pwndbg!\n"
    else
        sed -i "$parameter_del" $gdbinitfile
    echo -e "Please enjoy pure gdb!"
    fi

}

echo -e "Please choose one mode of GDB?\n1.peda    2.gef    3.pwndbg   4.pure_gdb"

read -p "Input your choice:" num

if [ $num -eq "1" ];then
    Mode_change $num
elif [ $num -eq "2" ];then
    Mode_change $num
elif [ $num -eq "3" ];then
    Mode_change $num
elif [ $num -eq "4" ];then
    Mode_change $num
else
    echo -e "Error!\nPleasse input right number!"
fi

gdb $1 $2 $3 $4 $5 $6 $7 $8 $9

还有安装方法：

echo $PATH
# 找一个系统变量指向的路径即可,我这里是/usr/local/sbin
cd /usr/local/sbin
# 安一个文件
sudo touch gdb.sh
# 赋予权限
sudo chmod -R 777 gdb.sh
# 将脚本放进去即可
vim gdb.sh
ctrl + v

如果之后使用不了，将.gdbinit照下列设计

#.gdbinit
set disassembly intel
#this place is controled by user's shell
#source ~/peda/peda.py
#source /home/hack/.gdbinit-gef.py
#source ~/pwndbg/gdbinit.py

要用哪个就把哪个前面的注释符号去掉就行。

很神奇的事情，有天晚上发现上面的脚本使用不了搞了两个多小时都无济于事，准备放弃了，然后将.gdbinit照上面改完以后突然又可以用了。。。

报错

Cloning into 'pwndbg'...
fatal: unable to access 'https://github.com/pwndbg/pwndbg/': Could not resolve host: github.com

就是网络错误，国内对github的访问太慢了，科学上网进行克隆。这边我瞎配置一段时间后错误，看到网上的文章自检出来了：

1、看看你的git配置
git config --global -l

如果有，将其从~/.gitconfig文件中删除，然后重试。

取消设置环境变量
env|grep -i proxy

遇到下面报错也别慌，是网速原因：

Cloning into 'ROPgadget'...
fatal: unable to access 'https://github.com/JonathanSalwan/ROPgadget.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated.

多尝试几遍就行了。

32位程序支持

必装的，不然等你碰到ELF.32bit运行不出来的时候有你傻眼的：

apt-get install libc6-dev-i386

arm的pwn环境qemu

sudo apt-get install qemu
sudo apt-get install qemu-system qemu-user-static binfmt-support

安装依赖：

sudo apt-get install -y gcc-arm-linux-gnueabi
sudo apt-get install qemu libncurses5-dev gcc-arm-linux-gnueabi build-essential gdb-arm-none-eabi synaptic gcc-aarch64-linux-gnu eclipse-cdt git

LibcSearcher

泄露libc库中函数的偏移的库，建议安装，可以节省时间，提高效率。

sudo pip install capstone
git clone https://github.com/lieanu/LibcSearcher.git
cd LibcSearcher
python setup.py develop

ROPgadget和one_gadget

ROPgadget是用来找gadget的，one_gadget用来寻找libc库中的execve('/bin/sh', NULL, NULL)可以一个gadget就可以getshell，建议安装。

# 先安装Capstone,它是一个轻量级的多平台架构支持的反汇编架构。
sudo apt-get install python-capstone

#安装ROPgadget
git clone https://github.com/JonathanSalwan/ROPgadget.git

#进入
cd ROPgadget

# 下载好ROPgadget解压，并进入文件夹中
python setup.py install

#安装one_gadget
sudo apt install ruby
gem install one_gadget

最后：

sudo apt-get update
sudo apt-get upgrade

以上就是wsl下ubuntu18.04LTS的pwn环境配置细节，感谢观看！
