Master configured to replicate to mispelled hostname

[Eric Krejci]

Well I am new to MySQL and am trying to setup replication, and I somehow got the master to try to replicate to a mispelled hostname. The other two replication pairs I setup work fine. The mispelled hostname doesn't exist or ping or anything but when I run:

mysqlrplshow --master=<repidname>:<pw>@<master> --discover-slaves-login=\<repidname>:<pw>

it connects to the master ok.
it tries to find the slaves and says

WARNING: Cannot connect to some slaves:
- <mistypedhostname>:<properport>: Can't connect to MySQL server on '<mistypedhostname>' (-2 Name or service not known)

I have tried these things:
On slave:
- logged in as rpl user
- STOP SLAVE;
- RESET SLAVE;
restarted services

same error.

Then i tried the same on both master and slave with service restart. I got the same error.

It feels like there is a configuration piece somewhere which tells it to replicate to that nonexistent server.

Are there other things I can try ?

Thank you for any help !
