- --->>>>       This is documented in the patch text.

- --->>>> For 10.24 and 11.04 install dtspcd using the following
- --->>>> procedure.  This bulletin will be revised when patches are
- --->>>> available for 10.24 and 11.04.

      1. Download dtspcd.tar.gz from the ftp site.
         This file is temporary and will be deleted when patches
         are available from the standard HP web sites, including
         itrc.hp.com.

          ftp site: hprc.external.hp.com (192.170.19.51).
          account: dtspcd
          password: dtspcd
          file: dtspcd.tar.gz

           If using a browser:

           ftp://dtspcd:dtspcd@hprc.external.hp.com/dtspcd/

           Note: There is an ftp defect in IE5 that may result in
           a browser hang.  To work around this:
             - Select Tools -> Internet Options -> Advanced
             - Un-check the option: [ ] Enable folder view for FTP sites

      2. Copy the dtspcd.tar.gz file to a protected directory
         and unpack it.
         If you wish to verify the md5 sum before unpacking the
         dtspcd.tar.gz file, please refer to:

               HPSBUX9408-016
               Patch sums and the MD5 program

          The md5 sum for dtspcd.tar.gz is:

         MD5 (dtspcd.tar.gz) = b122f84857f4da65b50d9926201608a1


      3. Install the new dtspcd file using the
         install_dtscpd script or some similar procedure.

         For example on a 10.20 system:

            ./install_dtscpd dtspcd.10.20

         Note: 10.24 systems should use dtspcd.10.20.
               11.04 systems should use dtspcd.11.00.
               On 10.24 and 11.04 (VVOS) systems the
               install_dtscpd should be run at SYSTEM.

      4. Each shar file contains the following README:
