TITLE: TF2214 - TCP Driver Timeout Upgrade

README FOR: TF2214

PRODUCT AND VERSION: 

UnixWare 2.02, and UnixWare 2.03

Abstract
--------

Incorporate timeout option in telnet.

Symptom
--------

The DOS/Windows Client has been rebooted without properly
terminating connected TCP/IP Server Services.  The services
are keep alive for two hours before being terminated by the
Server when it determines that the connection to the Client
is no longer valid.


SOLUTION SPECIFICS
------------------


Installation Instructions:  

DATATYPE: datastream

1.  Download the tf2214.Z and tf2214.txt files to the /tmp directory
    on your machine.

2.  Read the release notes contained in this file and follow the 
    instuctions to add the package to your system.

3.  Now become root, uncompress the file and add the package to your 
    system using the following commands:

        $ su
        # uncompress /tmp/tf2214.Z
        # pkgadd -d /tmp/tf2214


General Description.
-------------------

The System Administrator can modify the timeout option for
all TCP/IP Services by adjusting the following #defines in
/etc/conf/pack.d/tcp/space.c:

	TCP_TV_KEEP_INIT
	TCP_TV_KEEP_IDLE
	TCP_TV_KEEPCNT

NOTE: Changing any of these default settings impacts all
TCP/IP Services and is NOT RECOMMENDED.

If these values are changed, the UnixWare kernel must be re-built
to incoporate these changes.  To do this, execute the following
command as "root":

	/etc/conf/bin/idbuild -B

After this command is done, a system reboot will be needed to
install the new kernel.

New Features.
------------

Allows the System Administrator to modify timeout settings to
terminate TCP/IP Services when the Server determines that the
connection to the client is no longer valid.

Software Notes and Recommendations.
----------------------------------

This patch should only be installed on UnixWare 2.02 or 2.03
systems which have the Internet Utilities installed and on which
it is desired to modify the timeout parameters for TCP/IP Services.

This PTF is included in PTF2112 and does not need to be installed.

Testing of the modified software contained in this package has
been conducted only to the extent necessary to confirm that it
resolves the problem(s) stated above ("Symptom").  Such testing
consists of recreating the problem conditions and verifying that 
the problem no longer occurs.  No other testing of this software 
has been done.

Hardware Notes and Recommendations.
----------------------------------

This PTF is targeted for the i386, i486 and Pentium CPU's.
