 B. Recommended solution

**REVISED 12**
    Note: If the preliminary patches, PHNE_28929.depot or
          PHNE_28930.depot have been installed, they must
          be removed with swremove before installing the
          general release patches PHNE_28982 (11.00) or
          PHNE_28983 (11.11) or subsequent.

    Remove the preliminary patches with swremove
    if they are on the system:

      PHNE_28929.depot #B.11.00
      PHNE_28930.depot #B.11.11

     Install the appropriate patches.

          B.10.20 - PHCO_26158
 --> B.10.26 - PHCO_30063
          B.11.00 - PHNE_28982
          B.11.00 - PHCO_28480
          B.11.04 - PHCO_30407
          B.11.04 - PHNE_30168
          B.11.11 - PHNE_28983
          B.11.11 - PHCO_28481
          B.11.22 - PHNE_29449

     In addition install libc.1 for B.11.22
     as described below.

 --> Please write to security-alert@hp.com to obtain
 --> libc.1 for B.11.22.

      Verify the cksum or md5.

      cksum:
      3108550729 1867776 libc.1

 MD5 (libc.1) = 118ce482dbb3982b7484ddc434d77a51

      For B.11.22
      ====================================
      Install PHNE_29449 or subsequent and:

      #DIR=[path to new files]
      #cd /usr/lib
      #cp $DIR/libc.1 libc.1.new
      #chmod 555 libc.1.new
      #chown bin:bin libc.1.new
      #mv libc.1 libc.1.orig
      #mv libc.1.new libc.1

      Any applications that use libc.1 must be restarted.

      Rebooting is the recommended way to restart the applications
      using libc.1.
