Can you check this out: C | #include <stdio.h> char use - Anonymous - PLhjE5cG - Pastebin.com

The executable file takes one argument, a txt file that contains username and password.
I realize that the strcmp can be overflowed to overwrite the adjacent variables, but I don't know how to do it since I am new to this field.

Can you please tell me what kind of "input" i can use to overflow the function and thus be able to get the system to print "Welcome.." instead of "Connection refused", without knowing the user/pass combination?

I would really appreciate it, thanks!
