BItcoind/P2Pool What am I doing wrong? I am running latest bitcoind and p2pool releases (default port settings) on Fedora 21 with ports open for 3332-3333, 8332-8333, and 9332-9333.  Everything appears to be well when connecting to the BC net, but when one of my miners (Antminer S5) connects to http://myhostname/IP port 3333 p2pool will not respond.  When I try to connect with port http://myhostname/IP port 9333, I get a twisted error complaining about authentication, but when I try to connect to port myhostname/IP (stratum+tcp??) port 9333 it looks like the miner is trying to connect and get work, but after several seconds p2pool reports a "handshake timeout" for the miner IP address.  

This is the error I get:

What am I doing wrong?
The p2pool node communicates on more than one port. By default, miners connect to the node on port 9332 and other p2pool nodes ("peers") connect on port 9333.

So just switch your miner to port 9332, that should fix your issue.
