type. PTF137 contains updated versions of the ip and arp drivers. 
In addition, modified versions of the slink and slattach commands and 
the strcf data file are installed. This patch requires UnixWare 
version 1.1. The Internet Utilities (inet) package must also be currently
installed. This patch is replaced by update 1.1.2


SYMPTOM

3. Software Notes and Recommendations

PTF137 requires UnixWare 1.1 to be installed on the system. The Internet
Utilities (inet) package must also be currently installed. The system should
be in single user mode for the installation of PTF137.

If you choose to remove (un-install) PTF137 and restore your system to its
original condition, please enter the following command:

     # pkgrm ptf137

The "pkgrm" command is the recommended method to restore your system.
However, if "pkgrm" fails the following steps will enable you to
manually remove PTF137 and restore your system.

Enter:
# cp /var/sadm/pkg/ptf137/save/etc/conf/pack.d/ip/Driver.o
/etc/conf/pack.d/ip/Driver.o 
# chmod 0644 /etc/conf/pack.d/ip/Driver.o 
# chown root /etc/conf/pack.d/ip/Driver.o 
# chgrp root /etc/conf/pack.d/ip/Driver.o 
# cp /var/sadm/pkg/ptf137/save/etc/conf/pack.d/arp/Driver.o
/etc/conf/pack.d/arp/Driver.o
# chmod 0644 /etc/conf/pack.d/arp/Driver.o 
# chown root /etc/conf/pack.d/arp/Driver.o 
# chgrp root /etc/conf/pack.d/arp/Driver.o 
# cp /var/sadm/pkg/ptf137/save/usr/sbin/slink /usr/sbin/slink
# chmod 0500 /usr/sbin/slink
# chown root /usr/sbin/slink
# chgrp bin /usr/sbin/slink
# cp /var/sadm/pkg/ptf137/save/usr/sbin/slattach /usr/sbin/slattach
# chmod 0555 /usr/sbin/slattach
# chown bin  /usr/sbin/slattach
# chgrp bin  /usr/sbin/slattach
# cp /var/sadm/pkg/ptf137/save/etc/inet/strcf /etc/inet/strcf
# chmod 0444 /etc/inet/strcf
# chown root /etc/inet/strcf
# chgrp sys  /etc/inet/strcf
# rm -rf /var/sadm/pkg/ptf137
# /etc/conf/bin/idbuild

Once the kernel is rebuilt it is necessary to re-boot the system.


4. Hardware Notes and Recommendations

No specific Hardware.

5. Installation Instructions

Enter:
     # pkgadd -d diskette1

After a successful installation the following message is displayed:

     ***IMPORTANT NOTICE***

          If installation of all desired packages is complete,
          the machine should be rebooted in order to
          ensure sane operation. Execute the shutdown
          command with the appropriate options and wait for
          the "Console Login:" prompt.
     
Before executing a reboot it is necessary to configure one or more ethernet
cards to use Ethernet SNAP frames.  Edit the following file:

     /etc/confnet.d/inet/interface

and change the sixth field (see the beginning of the interface file for a
description of the fields) to:

     add_interface_ETHERNET_SNAP

For example, a interface entry that read:

     ie6:0::/dev/ie6_0:-trailers::

might be changed to:

     ie6:0::/dev/ie6_0:-trailers:add_interface_ETHERNET_SNAP


Any interface file entries that are not modified will continue to use the
Ethernet(c) II frame type.

Once modification of the file /etc/confnet.d/inet/interface is complete,
reboot the system.
