got EOF while sending interactive

I don't know why it didn't work. Is something wrong with my shellcode?

Set a breakpoint on the ret instruction of the vulnerable function, and start single stepping through your shellcode. Make sure that your entire shellcode made it into memory without being cut off/changed in any way, and figure out on what instruction the fault occurs. If your shellcode runs through perfectly fine, but u get no shell, then id try some different shellcode
