Patch Name:  PHNE_1904

Patch Description: Connection endpoint remains in FINWAIT-1 and FINWAIT-2

        Connection endpoint remains in FINWAIT-1 and FINWAIT-2 forever.
        When doing a "netstat -A" customers see that some connections
        are hung in FINWAIT-1 or FINWAIT-2. This happens if the TCP
        shutdown handshake was not completed successfully. Keepalive,
        set by SO_KEEPALIVE, did not work in these two states so
        the connection endpoint could hang around forever. This patch
        allows keepalive to work in FINWAIT-1 and FINWAIT-2 if the
        socket application has set SO_KEEPALIVE.

After getting the patch onto your machine, unshar the patch
(sh PHNE_1904)

To install this patch do the following:
1) Run /etc/update (Note: you must be root to update a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return"
   or "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: PHNE_1904.updt" assuming
   you are in the directory where PHNE_1904.updt has been placed.  In some
   versions, you may need to enter the absolute path name.  In others, the
   default "/dev/rmt/0m" may not appear in the field as default.
5) Press "Done".
6) Move to the "Select All Filesets on Source Media" line and press "Return".

The customized script that update runs will move the original software
to /system/PHNE_1904/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended
that you move the PHNE_1904.text file to /system/PHNE_1904 to be
retained for future reference.

If you wish to put this patch on a magnetic tape and update from the
tape drive, dd a copy of the patch to the tape drive.  As an example
the following will create a copy of the patch that update can read:

    dd if=PHNE_1904.updt of=/dev/rmt/0m bs=2048
