7. Set the username and password for each EMS host:

c. From the drop-down list, select the EMS host.
Note If the EMS hostnames are not in the list, EMS may not be enabled.
d. In the Username field, type a username for that host.
e. In the New Password field, type a password for the user.
f. Retype the password in the New Password (again) field.
g. Click Update.
h. Repeat steps c-g for each additional EMS host defined in the configuration file.
Note Follow this procedure to change a password after it is set.
8. If you configured EMS to use SSH, you must log in to each host server to verify and accept
the fingerprint. When the fingerprint is accepted, the host server’s key is stored in /home/
bill/.ssh/known_hosts on the VTS server and used to authenticate the key during
subsequent logins.
Be careful when accepting keys from remote hosts, to prevent security breaches. A key
mismatch can occur because the key has been changed on the host server or because a
“man in the middle” exploit is being attempted, which could be used to obtain login
credentials. If the key does not match, EMS will not log in.
Complete these steps to accept the fingerprint:
a. Log in to the host server.
b. Change to the bill user:
su - bill
The following message is displayed:
The authenticity of host 'host (ip_address)' can't be established.
DSA key fingerprint is fingerprint.
Are you sure you want to continue connecting (yes/no)?
