I've been experimenting with Tomoyo Linux lately. To me, it's the simplest LSM to reason about (although I have misconfigured it before). In the spirit of Russell Coker's SELinux play machine, I have an initial Tomoyo test machine that users may experiment with as root (uid 0). Feel free to ssh in and try it out. If you find an issue, or bypass Tomoyo somehow, please don't damage anything and let me know. Also, please no fork bombs. You don't need root to do that:

    ssh -x -a [email protected]
    Password = tomoyo1
