I'm getting the following (no source/binary file... is it part of the challenge or is there something wrong?):

    level01@ctf:~$ pwd;ls -al
    /home/level01
    total 24
    dr-x------ 2 level01 root    4096 2012-02-22 13:28 .
    drwxr-xr-x 9 root    root    4096 2012-02-22 13:28 ..
    -rw-r--r-- 1 level01 level01  220 2010-04-19 02:15 .bash_logout
    -rw-r--r-- 1 level01 level01 3103 2010-04-19 02:15 .bashrc
    -rw------- 1 level01 root      11 2012-02-22 13:28 .password
    -rw-r--r-- 1 level01 level01  675 2010-04-19 02:15 .profile

Earlier quoted context omitted.

Stuck at level3 for a minute

Same, the only thing I can think of is doing something with the pointers in the fns variable in main, but I can't quite figure out what to do.

I've been playing with nm, but without a hex editor I feel crippled :/
