VERITAS Enterprise Administrator UserÆs Guide 5.0 (September 2006)

28 Using the VEA
Connecting and disconnecting hosts and domains
Note: Entries for the user name and password must exist in the password file or
corresponding Network Information Name Service (NIS) table on the machine to be
administered.
Logon authentication
There are three authentication mechanisms by which a connection can be established with
the server.
■ Silent Logon (Windows platforms only): This happens when the server is local; that
is, the VEA client and server both are running on the same machine. If the user has
logged on with administrator privileges, then username and password are not
required. (The basic connection dialog box is used.)
■ Native Logon: Username and password are required to authenticate the user. (The
expanded connection dialog box is used.)
■ DCOM authentication (Windows platforms only): If the user has logged in as
administrator on the domain, then username and password are not required to
authenticate the user (the basic connection box is expanded after entering the server
name and clicking OK), and the user is connected to the server. The server needs to
be started with administrator privileges for this type of authentication.
If the user does not have administrator privileges, then the connection takes place
using the Native Logon mechanism.
Disconnecting from a host
The Disconnect procedure disconnects a host machine from the current VEA session.
When a host machine is disconnected, VEA cannot administer that machine until a new
connection is made.
1 Right-click the computer icon to be disconnected.
2 Select Disconnect from the file menu on the menu bar.
3 A confirmation dialog will appear, click Yes to end the remote connection.
4 The computer icon disappears from the left tree view.
If the connection is lost for any other reason, a message appears that indicates the
connection has been terminated, and the icon for that computer is removed from the left
tree view. You need to click OK to close the message box.
To restore access to a disconnected host machine, you must reconnect to the host.
