Installation Procedure:

To install InternetCT perform the following steps:
     1. The  request sets  (definitions) used  by   InternetCT are  on the
        Request installation  diskette.  The request sets must be installed
        and  the  affected processor(s)  rebooted  before InternetCT  will
        operate.
        Note: Request 10.0 or later is required with this product.
     2. If  this is to  be a  cluster installation be  sure you log  out or
        turn off all other workstations in the cluster.
     3. Insert    the   InternetCT   distribution    diskette   into   the
        workstation's diskette drive.
     4. Submit  the file [f0]<sys>HdInstall.sub  or use either  the command
        Software  Installation or Install  (if your system supports  one of
        these commands).
     5. The installation of the software will proceed to completion.
     6. Please  consult  the  samples  in  the  <Sample> directory  of  the
        distribution diskette for configuration of InternetCT.

The installation of InternetCT is independent of any other software and
may be performed at any time.

NOTE: The installation procedure creates the INetCT directory for
approximately 300 files. If you expect to maintain a large number of SMTP
messages you may wish to create the INetCT directory with a greater number
of files before you perform the installation described above.

If you are installing the software on a Megaframe SRP simply install the
software at any convenient cluster workstation. Note that in a cluster
environment the software will be installed on the system disk of the master
workstation. Be sure that all other workstations in the cluster are logged
out or turned off during the installation procedure.

Memory and disk requirements:

The Transport_ARPA service requires 200Kb plus user specified buffer memory in
the master workstation or SRP. Using the 40Kb default value for buffer
memory makes the total memory requirement 240Kb.

Approximately 1200 sectors of disk space are required on the master
workstation to install InternetCT.
