This is the new RC5DES v2.7100.412 client for IBM S/390
servers running the OS/390 operating system.

The client code has been ported and tested on an IBM 9672 System
running OS/390 V2R5. Currently the client is single threaded. In
order to exploit multiple CPUs on an SMP system, start multiple
instances of the client.

Currently neither the HTTP enconding nor SOCKS support is available
in this client. It depends on a direct connection to a keyserver or
keyserver proxy.


There are 2 installation procedures:

1) download and unpack on a non S/390 system

   o  unpack the archive to some temp directory for instance like:

      tar xvzf rc5des412-os390-nomt.tar.gz

   o  you will get 3 files:

          1629 May 27 17:27 Readme.OS390
         12638 Apr 28 23:38 Readme.txt
        716800 May 25 22:32 rc5des

   o  the Readmes are in ASCII and you can read them right away,
      in fact, you are reading them already ;)

   o  The 'rc5des' is a binary file which only runs on an IBM S/390
      mainframe system. ftp it to the target system in binary, do
      a 'chmod +x rc5des', then you can execute it like:

      'rc5des -config'



2) download and unpack on a S/390 system

   o  ftp the rc5des412-os390-nomt.tar.gz to the target IBM S/390 machine

   o  gunzip rc5des412-os390-nomt.tar.gz
      if you don't have 'gunzip', to obtain it, go to:
         
               http://www.s390.ibm.com/oe/bpxqp1.html

   o  export A2E='-o from=ISO8859-1,to=IBM-1047'

   o  pax $A2E -rf rc5des412-os390-nomt.tar

*) o  pax -rf rc5des412-os390-nomt.tar rc5des

   o  chmod +x rc5des


*) The reason why this statement is there is because the tar archive
   contains files which need to be translated from ASCII to EBCDIC
   during extracting them from the archive, and it also holds a binary
   executable (rc5des) which gets garbled by applying this translation.
   the 2nd call to pax extracts the binary 'straight', without applying
   any conversion. Sorry for the confusion, I don't know (yet) of a
   way to ship binary and ASCII data in a tar archive and treat them
   separately via one call to 'pax'.
