c. Enable EMS and configure the settings, as described in the help. To view the help,
click the Help button at the top of the page.
4. Set the username and password for each EMS host:
a. Click Security→Passwords on the navigation pane. The following page is displayed:
b. Configure a password for each EMS host defined in the configuration file. Click Help
for complete instructions.
5. 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 VTS server.
b. Change to the bill user:
su - bill
c. Use SSH to connect to the host server:
ssh -l username host_server
where username is the user name on the host server (such as SUPER.USER) and
host_server is the host name of the host server.
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)?
