A successful installation is indicated by the return of the command prompt with no errors. See Appendix 1 for example
output of several installations.
Once the client is installed, the lce-server and server-port options must be configured if it will connect to a LCE 4.0
server. Next, restart the client for it to make an initial connection to the LCE server. Using SecurityCenter, LCE Manager
4.6, or LCE Client Manager on the LCE server, allow the server to accept the connection and configure the client.
After configuration by the LCE Client Manager, the lce_client.conf file is no longer used to manage the client. The
server_assignment.xml file details the connection information from the client to the LCE server. The client policy file
is copied to the client with the .policyf file instructing the client which policy file to load. It is not recommended to edit
these files directly unless instructed to do so by Tenable Support.

Upgrading the LCE Clients
LCE Clients 3.4.3 and greater can be upgraded by performing a basic install or upgrade process, depending on the
method. During the installation or upgrade process, the original LCE Client is removed automatically and the new one is
then added. Follow the instructions above for performing the LCE Client installation, replacing ‘-ivh’ with ‘-Uvh’.
After upgrading clients, they must be configured by the LCE Client Manager of the LCE server if they are version 4.0 or
higher.
Removing the LCE Clients
To remove the LCE Client, login as the root user or equivalent, stop the client daemon (see the section “Halting the LCE
Linux and Unix-Based Clients” for directions) and run the appropriate commands for your client and platform as shown in
the following table:
