I installed p2pool on my server for triple merged mining - VTC, MON, PLX. Server is running smoothly, but I don'know how to setup my addreses in miner. I have read that you can add for example MON address in password field, but what if you mining more than two coins, where put the addresses?
You actually don't use the addresses, but the RPC info for the daemons. For example you'd start the pool with the following switches:
python run_p2pool.py --net vertcoin3 --merged http://*RPCuser1*:*LongRPCpass1email@example.com:6888 --merged http://*RPCuser2*:*LongRPCpassfirstname.lastname@example.org:7817
You will see "Got new merged mining work!" in console as confirmation.
