3.2.1 CDE - de-installing CDE

Information

The recommendation is to de-install CDE from the system, assuming that it is not required and is already installed.

Rationale:

CDE has a history of security problems and should be disabled.

NOTE: If CDE is required, it is vital to patch the software and consider TCP Wrappers to further enhance security.

Solution

Identity if CDE is already installed:

lslpp -L |grep -i CDE

If there are CDE filesets installed - de-install them if CDE is not required. For each fileset preview the de-installation:

installp -up <fileset name>

Review the fileset removal preview output, paying particular attention to the other pre-requisites that will also be removed. Typically only X11.Dt filesets should be de-installed as pre-requisites. Once reviewed, de-install the fileset and pre-requisites:

installp -ug <fileset name>

NOTE: Repeat until all CDE filesets are de-installed

Default Value:

N/A

Additional Information:

Reversion:

Re-install the CDE software from the AIX media.
