[已解决]pwntools使用gdb.attach(pid)后，按ni就直接退出了。

Waiting for debugger时就检测不到debugger。然后fin或者ni直接退出。
流程
1 2 3 4 | 1.程序执行-提示输入2.$ gdb attach pid # waiting for debugger , 新窗口中自动打开gdb3.gdb$ ni # 这里卡住 |
Ctrl+C中断后如下,研究中
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | Traceback (most recent call last): File "/home/kali/vmware/pwn1/a2.py", line 3, in <module> gdb.attach(p) File "/home/kali/.local/lib/python3.9/site-packages/pwnlib/context/__init__.py", line 1524, in setter return function(*a, **kw) File "/home/kali/.local/lib/python3.9/site-packages/pwnlib/gdb.py", line 1050, in attach proc.wait_for_debugger(pid, gdb_pid) File "/home/kali/.local/lib/python3.9/site-packages/pwnlib/util/proc.py", line 338, in wait_for_debugger debugger = psutil.Process(debugger_pid) File "/usr/local/lib/python3.9/dist-packages/psutil/__init__.py", line 326, in __init__ self._init(pid) File "/usr/local/lib/python3.9/dist-packages/psutil/__init__.py", line 354, in _init self.create_time() File "/usr/local/lib/python3.9/dist-packages/psutil/__init__.py", line 710, in create_time self._create_time = self._proc.create_time() File "/usr/local/lib/python3.9/dist-packages/psutil/_pslinux.py", line 1576, in wrapper return fun(self, *args, **kwargs) File "/usr/local/lib/python3.9/dist-packages/psutil/_pslinux.py", line 1788, in create_time ctime = float(self._parse_stat_file()['create_time']) File "/usr/local/lib/python3.9/dist-packages/psutil/_pslinux.py", line 1576, in wrapper return fun(self, *args, **kwargs) File "/usr/local/lib/python3.9/dist-packages/psutil/_common.py", line 450, in wrapper return fun(self) File "/usr/local/lib/python3.9/dist-packages/psutil/_pslinux.py", line 1619, in _parse_stat_file data = f.read() |
脚本执行attach 失败
1 2 3 4 | from pwn import *p=process('./ret2shellcode')gdb.attach(p)# 如图, 没断在程序中, fin直接退出了, 按ni没回显 |
无脚本 attach成功
1 2 3 4 5 6 | # ./level1 提示输入, 新建窗口找到pidgdbattach pid# 回程序输入字符ni# 成功断在下一步 |
gdb file成功
1 2 3 4 5 6 | gdbfile level1b mainrni# 正常启动 |
直接gdb运行再attach pid也不可以。但是要手动、麻烦。
安装过程。
1.新安装系统
2.安装pwntools
3.安装pwndbg
4.脚本调试
尝试了
kali版本. 2020.1,2020.2,2020.3,,2020.4,2021.1, 2021.2都不行。
Ubuntu_mini(70M)在线安装的版本。不正常。
Uubuntu20桌面环境下正常。
有没有pwndbg都有这问题。
