<p>You need to attach a miner to the p2pool to actually mine BitCoins.  Try something like <a href="https://bitcointalk.org/?topic=3878.0" rel="nofollow">GUIMiner</a>.</p>

There is no miner attached to the pool, "0H/s" means zero hashes per second. And since no hashing is being performed the dead on arrival and time to share cannot be calculated, and thus are unknown.

Since mining is not occurring, the stale rate and the efficiency cannot be calculated, and thus are unknown.

You need to attach a miner to the p2pool to actually mine BitCoins. Try something like [GUIMiner](https://bitcointalk.org/?topic=3878.0).
