docker4gdb.txt

Problem:

จะเอา IDA Pro มา remote debug binary ใน linux container ขึ้นว่า

root@c8a5bde5162d: ~# gdbserver 0.0.0.0:4444 ./main
gdbserver: linux_ptrace_test_ret_to_nx: Cannot PTRACE_TRACEME: Operation not permitted
gdbserver: linux_ptrace_test_ret_to_nx: status 256 is not WIFSTOPPED!

Solution:

$ docker ps
$ docker commit <container-id> linux4gdb
$ docker run -it \
>   --name linux4gdb1 \
>   --privileged \
>   --security-opt=apparmor:unconfined \
>   -v ~/path/to/share/:/path/to/share/ \
>   -p 4445:4445 \
>   linux4gdb
$ gdbserver 0.0.0.0:4445 ./main
Process ./main created; pid = 26
Listening on port 4445
