RealSecure: RSfN 6.5 patch to address SIGCHLD errors
  
ISS RealSecure for Nokia,
for version: 6.5 Only
 
  
date modified: 05/17/2002

This patch addresses issues where communication between the Event Collector
and RealSecure sensor stops and the sensor must be restarted. This is caused
by a memory leak issue which results in the following SIGCHLD error

"ISS[25140]: (network_sensor_name) - The Application received unexpected
SIGCHLD signal 20. The engine will exit."

Please Note: XPU 4.3 must be applied to the network sensor before applying
the patch.

 
SOLUTION

To install the patch use the following guidelines:

1) Start with a fresh install of RealSecure Network Sensor ver. 6.5 on IPSO
3.4.1-FCS10

a) If an uninstall was performed beforehand, please remove the /opt/ISS
directory before installing the RSfN 6.5 package. (rm -R /opt/ISS)

b) You may wish to backup the .PubKey files to save you from having to
re-copy those up after the install.
(Located under /opt/ISS/RealSecure6_5/Keys/CerticomNRA).

2) Apply XPU 4.3 to the sensor.

3) Once your RSNS6.5 install is completed, you will want to shutdown the
issdaemon (
/opt/ISS/issDaemon/issd -stop)

4) Make backups of the following files located in the /opt/ISS/RealSecure6_5
directory that will be replaced.

* issCSF
* libNetworkSensor.so
* CmnRspnses.so
* NSRspnses.so
* rsDisplay.so

5) Copy the files contained in the ipso_patch.tar.gz you download up to the
/opt/ISS/RealSecure6_5 directory.

6) Reboot the sensor.

Note: If you have dual sensors running on the Nokia Appliance you have to
apply the patch to the second sensor files located in the
/opt/ISS/network_sensor_2 directory

Yah This appears to be the same issue, which I've been encountering for
roughly a month now, we'll see if this patch works properly.

Could be this known issue that I found on the Nokia support site.

I guess ISS can provide the patch too.

Hey has anyone encountered the nokia sensor crashing arbitrarily, (i'm aware
of the dhcp issue that signature is turned off in my policy). Here is the
information I receive from the logfile:

Jun 3 11:08:18 sentinel [LOG_ERR] ISS[2703]: (network_sensor_1) - The
Application received unexpected SIGCHLD signal 20. The engine will exit.
