    I'd use GDB if I were you. Much better and It's been integrated on nix systems for like ever. PM me if you want I may be able to help with the exploit.

    Yeah i use GDB as well, but this is a windows file and its easier to use other things, anyway i found its just that particular software that didnt crash in the debugger as itried another one and it did which is strange

    That is strange. Maybe ollydbg has something like a anti-stack smashing function?

    I checked it .. Even the SEH chain is not getting overwritten .. Very hard to exploit(if it is exploited ) .. Thats why 0v3r left it .. He is a pretty good buffer overflow exploit writer himself :)

    Try immunity debugger. I haven't tried it, but I prefer immunity dbg anyway.

    Immunity is nothing more than Olly with cosmetic changes

    ...he did use Immunity...

    McKittrick, they have their differences
    while( !(succeed = try() ) );

    the page i saw once in someone describing it went something like "this is Ollydbg with just more eye candy. it is pretty much the exact same tool copied over"

    i ran both and saw no differences
