 B. Fixing the problem

   Check for Apache Installation
   -----------------------------
   To determine if the Apache web server from HP is installed on
   your system, use Software Distributor's swlist command. All
   three versions products may co-exist on a single system.

   For example, the results of the command
     swlist -l product | grep -i apache

     ApacheStrong 1.3.27.01 HP Apache-based Web Server
                                 with Strong (128bit) Encryption
     HPApache 2.0.39.01.02 HP Apache-based Web Server

   Stop Apache
   -----------------------------
   Before updating, make sure to stop any previous Apache binary.
   Otherwise, the previous binary will continue running,
   preventing the new one from starting, although the installation
   would be successful.

   After determining which Apache is installed, stop Apache with
   the following commands:

     for ApacheStrong: /opt/apache/bin/apachectl stop
     for HPApache: /opt/hpapache2/bin/apachectl stop

   Download and Install Apache
   -----------------------------
   - Download Apache from Software Depot:
     <http://www.software.hp.com>
   - Verify successful download by comparing the cksum with the
     value specified on the installation web page.
   - Use SD to swinstall the depot.

   Installation of this new version of HP Apache over an existing
   HP Apache installation is supported, while installation over a
   non-HP Apache is NOT supported.

   Removing Apache Installation
   ----------------------------
   If you prefer to remove Apache from your system instead of
   installing a newer version to resolve the security problem,
   use both Software Distributor's "swremove" command and also
   "rm -rf" the home location as specified in the rc.config.d file
   "HOME" variables.

   To find the files containing HOME variables in the
   /etc/rc.config.d directory:

     %ls /etc/rc.config.d | grep apache
        apacheconf
        hpapache2conf
        hpws_apacheconf

   For customers with HP-UX release B.11.04 (VVOS), stop Apache
   (as above), and install the patches listed above.
