Problem Description:

4926941 sunscreen 3.2 pmap state engine dropping NULL procedure
4913304 Retransmission FIN packet is dropped in CLOSING state
4959989 Fin Ack does not change state to ESTABLISHED
 
(from 109737-12)
 
4837929 Unable to use ifconfig to remove SunScreen module from network interface.
4795556 ssadm logdump command hangs after some minutes
4389132 wrong version number of new created policy shown.
4433735 security home page URL at welcome screen should pop-up new browser window.
4861572 Sunscreen 3.1 network connectivity slows to unusable level
4890614 Patch 109734-09 breaks nattables command.
4801062 Customer want's less descriptive log, to not resolve hostname. only IP addresses
 
There is a new -r option to the logdump commnd, this forces logdump not
to use the name service to resolve IP addresses to names.
 
Example:
 
ssadm log get | ssadm logdump -i  -r
 
statetable_summary
------------------
 
This script is provided to aid diagnosis of performance problems caused by
large state tables. The performs analysis on a file containing the output
from one of:
 
ssadm lib/statetables
ssadm lib/nattables
ssadm lib/screeninfo
 
Usage:
 
/usr/lib/sunscreen/support/statetable_summary file_to_analyse
 
The output is written to stdout and files in /var/tmp
 
This script can be run on a system with SunScreen installed in which case
it will run the statetables & nattables commands directly if an input file
is not specified.
 
If an input file is provided then the script can be run on any Solaris
system, it does not have to be run on the screen. In many cases this
is desirable because the script can take a very long time to run and
generate significant load on the system if the statetable it is analysing
is very large.
 
As with all programs in /usr/lib/sunscreen/support this is
provided for support purposes only and not a supported part of the product.

Patch Installation Instructions:
--------------------------------
See Special Install Instructions.

Special Install Instructions:
-----------------------------
 
Installation Instructions for the Administration Station
--------------------------------------------------------
 
1. Become root on the Administration Station.
 
2. If you are running Solaris 2.6 on the administration station, ensure
   that you have already installed the latest version of Solaris patch 106126.
   Version 106126-06 is available on your EFS 3.1 CD. 
 
3. Transfer the patch file to the Administration Station.
 
4. Then type:
 
        # uncompress 109737-13.tar.Z
        # tar xf 109737-13.tar
        # patchadd 109737-13
 
 
Installation Instructions for Locally Administered Screens
----------------------------------------------------------
 
1. Become root on the Screen.
 
2. If you are running Solaris 2.6 on the Screen, ensure that you have 
   already installed the latest version of Solaris patch 106126-06.
   Version 106126-06 is available on your SunScreen EFS 3.1 CD.
 
3. Transfer patch file to the Screen using a diskette or ftp (with 3 MB free).
 
4. Type the following:
        # uncompress 109737-13.tar.Z
        # tar xf 109737-13.tar
        # patchadd 109737-13
 
5. Reboot the Screen.
 
 
Instructions for Remotely Administered Screens in Stealth Mode
--------------------------------------------------------------
 
Use this procedure ONLY if you cannot otherwise transfer the patch to 
the Screen.
 
1. Become root on the Administration Station.
 
2. If you are running Solaris 2.6 on the Screen, ensure that you have 
   already installed the latest version of Solaris patch 106126-06.
   Version 106126-06 is available on your SunScreen EFS 3.1 CD.
 
3. Transfer the patch file to the Administration Station.
 
4. Type the following:
        # ssadm -r <Name_of_Screen> patch install < 109737-13.tar.Z
 
Installation Instructions for High Availability (HA) clusters.
--------------------------------------------------------------
 
 
1. Determine which screen is ACTIVE within the HA Cluster using the following
   command on each:
 
        # ssadm ha status
 
2. Follow appropriate patch installation instructions from this README file to 
   install the patch on the CURRENTLY ACTIVE SCREEN within the HA Cluster 
   (determined from the previous step).
 
3. Be sure to reboot that screen upon completion of the patch installation.
 
4. After the reboot, the screen which the patch was just installed on 
   will come up in PASSIVE mode and some other member of the HA cluster
   will become ACTIVE.
 
5. Repeat steps 1-4 until the patch has been applied to all members of 
   the HA cluster.
 
Notes on patching HA clusters:
 
If the patch is installed on a PASSIVE screen before it is installed on an
ACTIVE screen, the HA daemon ss_had can core dump, this gives symptoms similar
to bug 4347381.
 
The SunScreen HA model works by having 2 or more firewalls in parallel. Both
firewalls see the same packets and hence calculate the same statetable entries.
If a packet matches a statetable entry , then it is passed through the screen.
 
If the ACTIVE screen is rebooted, one of the PASSIVE firewall(s) will take over. 
Existing connections will still be maintained as the PASSIVE firewall(s)
which has just become ACTIVE will have the statetable entries.
 
Once the originally ACTIVE firewall has been rebooted, it will have an empty
statetable. This firewall will add any new connections made since it was 
rebooted to its statetable, but will not know about connections established
before it was rebooted. If the currently ACTIVE screen is rebooted , some 
connections may get dropped.
 
Its not possible to say exactly how long it will take for both (all) the 
firewalls to have the same statetable entries as this will depend on the
type of connection being passed and the lifetime of this connection. 
Running the following command on both (all) firewalls in the cluster will
give the administrator a good indication of when it is safe to reboot 
the second firewall, without significant loss of service:
 
	# ssadm lib/statetables | grep ESTABLISHED | wc -l
 
 
Instructions for Identifying Patches Installed on System
--------------------------------------------------------
 
1. To identify the patch level on your locally administered Screen,
   type the commands:
 
        # ls -lt /var/sadm/patch > screen.pkginfo
        # pkginfo -l >> screen.pkginfo
 
2. To identify the patch level on your remotely administered Screen
   in stealth mode: 
 
        # ssadm -r <Name_of_Screen> lib/support packages > screen.pkginfo
 
   This shows (1) ls -lt /var/sadm/patch, (2) pkginfo -l, and
   (3) the contents of /var/log/patch.log.
 
3. To identify the patch level on your Administration Station, type 
   the commands:
 
        # ls -lt /var/sadm/patch > admin.pkginfo
        # pkginfo -l >> admin.pkginfo
 
 
Instructions to remove the patch on the Administration Station
--------------------------------------------------------------
 
1. Become root on the Administration Station.
 
2. Then type:
 
        # patchrm 109737-13
 
 
Instructions to Remove the Patch on Locally Administered Screen
---------------------------------------------------------------
 
1. Become root on the Screen.
 
2. Type the following:

Instructions to Remove the Patch on Remotely Administered Screens in 
Stealth Mode
--------------------------------------------------------------------
 
Use this procedure ONLY if you cannot otherwise obtain access to a 
login prompt on the Screen.
 
1. Become root on the Administration Station.
