Server User Manual

Next, you must register the Public Key as an Authorized Key on the Slave. In a case that has only one
Master with multiple Slaves, you only need to upload the one RSA or DSA public key for each Slave.
Note Using key pairs can be confusing since one file (Public Key) fulfills two roles— Public Key and
Authorized Key. For a more detailed explanation, refer to the Authorized Keys section of Chapter
15.6. Also, refer to this chapter if you need to use more than one set of Authorized Keys in the
Slave.
 Select System: Administration on the Slave’s Management Console.
 Browse again to the stored RSA (or DSA) Public Key and upload it to Slave’s SSH Authorized Key.
 Click Apply.
The next step is to Fingerprint each new Slave-Master connection. This one-time step will validate that
you are establishing an SSH session to who you think you are. On the first connection, the Slave will
receive a fingerprint from the Master which will be used on all future connections:
 To establish the fingerprint, first log in the Master server as root and establish an SSH
connection to the Slave remote host:
# ssh remhost
