2.3. Installing and Uninstalling the Enterprise Security Client on Red Hat Enterprise Linux
2.3.1. Installing the Client
The first step in installing the Enterprise Security Client is to download the required packages. There are two ways to obtain the packages:
- Downloading an ISO image from the Customer Portal.
- Using the Red Hat
yumutility
The preferred method of obtaining RPMs is using the
yum command-line utility, as follows:
# yum install esc
If the
yum command completes successfully, all of the necessary Enterprise Security Client RPMs will be installed and ready for use.
Note
If the
yum utility was used to install the Enterprise Security Client, there is no need for further installation; the client has already been installed. The following procedure is for installing from a CD image.
- As
root, install the Enterprise Security Client packages:yum install esc
The Enterprise Security Client is located in
/usr/lib/esc-1.1.0 on Red Hat Enterprise Linux 32-bit systems and /usr/lib64/esc-1.1.0 on Red Hat Enterprise Linux 64-bit system. The esc shell script is installed in /usr/bin/esc. The Enterprise Security Client can be launched by typing esc at a command prompt.
The Enterprise Security Client for Linux implements a daemon (
escd) which runs silently, waiting for a smart card to be inserted. When an unenrolled smart card is inserted, the daemon automatically launches the client UI, and the Enterprise Security Client guides the user through the enrollment process. The client can also be launched manually by selecting System Settings, then Smart Card Manager, from the menu.
2.3.2. Uninstalling on Red Hat Enterprise Linux
- Unplug all USB tokens.
- Stop the Enterprise Security Client.
- Log in as
root, and userpm -evto remove the Enterprise Security Client RPM:# yum remove esc
Note
Update the version numbers of the RPM files to match your version. - Remove any remaining files in the installation directory.
