Dear SCO Customer,

Support Level Supplement (SLS) ptf7213b, the UnixWare 7.0.1 ping Supplement,
addresses these problems found with the ping command on UnixWare 7.0.1:

    1. ping hangs and never times out.  This occurs when alarm(1) 
       becomes stuck in a loop of retries.

    2. ping -f fails.
 
    3. ping -s and ping -i will ping continuously.


SLS ptf7213b contains:

        /usr/sbin/ping


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

SLS ptf7213b should only be installed on:

        UnixWare 7 Release 7.0.1

If your system is running any libraries or commands that are contained in 
this SLS, then these programs will continue to run with the old versions of 
these libraries or commands until the system is rebooted.

Note that when all necessary patches have been installed, it is good practice 
to reboot the system at the earliest opportunity. This will ensure that no 
programs continue to run with the old libraries or commands.

        # pkgadd -d /tmp/ptf7213b
