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.
