Updated code in /usr/local/sbin/nsm_sensor_ps-start:

    # Start IDS Engine with unified2 output
    # Determine whether to use Suricata or Snort (default)
    if grep -i "suricata" /etc/nsm/securityonion.conf >/dev/null
    then
        # Start Suricata
        [ -z "$SKIP_SNORT_ALERT" ] && process_start "suricata" "--user $SENSOR_USER --group $SENSOR_GROUP -c /etc/nsm/$SENSOR/suricata.yaml --af-packet=$SENSOR_INTERFACE_SHORT --runm
ode=autofp -F /etc/nsm/$SENSOR/bpf.conf -l $SENSOR_LOG_DIR " 
"$PROCESS_PID_DIR/$SENSOR/suricata.pid" "$PROCESS_LOG_DIR/$SENSOR/suricata.log" 
"suricata (alert data)"

Updated code in /usr/local/sbin/nsm_sensor_ps-restart:

    # restart the IDS engine
        if grep -i "suricata" /etc/nsm/securityonion.conf >/dev/null
    then
        [ -z "$SKIP_SNORT_ALERT" ] && $ACTION "suricata" "--user $SENSOR_USER --group $SENSOR_GROUP -c /etc/nsm/$SENSOR/suricata.yaml --af-packet=$SENSOR_INTERFACE_SHORT --runmode=au
tofp -F /etc/nsm/$SENSOR/bpf.conf -l $SENSOR_LOG_DIR" 
"$PROCESS_PID_DIR/$SENSOR/suricata.pid" "$PROCESS_LOG_DIR/$SENSOR/suricata.log" 
"suricata (alert data)"

Added the following to security-onion-upgrade.sh:

sed -i 's| |=|g' $CONF
source $CONF

        NEW="20120329"

        DIR="/nsm/backup/$NEW"
        mkdir -p $DIR                                           | $LOGGER
        cd $DIR

        for FILE in securityonion-nsmnow-admin-scripts_20120329_i386.deb; do
                echo -n "* Downloading $FILE..."                | $LOGGER
                wget -q http://sourceforge.net/projects/security-onion/files/$NEW/$FILE -O $FILE | $LOGGER
                if [ $? -eq 1 ]; then
                        echo "FAIL"     | $LOGGER
                        exit 1
                else

                fi
        done

        echo -n "* Installing downloaded packages..." | $LOGGER

        if [ $? -eq 1 ]; then
                echo "FAIL"     | $LOGGER
                exit 1
        else
                echo "OK"       | $LOGGER
        fi

        SENSORS=`grep -v "^#" /etc/nsm/sensortab |awk '{print $1}'`
        for SENSORNAME in $SENSORS; do
                echo "* Creating /etc/nsm/$SENSORNAME/bpf.conf if it doesn't already exist"       | $LOGGER
        touch /etc/nsm/"$SENSORNAME"/bpf.conf
        done

        sed -i "s|VERSION=$VERSION|VERSION=$NEW|g" $CONF        | $LOGGER
        echo "* Upgrade to $NEW complete."                      | $LOGGER
        echo 
fi

Turned over to testing:

Security Onion Testers,

Security Onion 20120328 is ready for testing!  This update should resolve the 
following issues:
http://code.google.com/p/security-onion/issues/detail?id=114
http://code.google.com/p/security-onion/issues/detail?id=224
http://code.google.com/p/security-onion/issues/detail?id=242
http://code.google.com/p/security-onion/issues/detail?id=243

Please only test on VMs that can be snapshotted.

Please test/verify the following:

- Start with a VM with the latest Security Onion and run Setup (choosing Snort 
- Suricata afpacket mode currently doesn't support bpf) so that we can simulate 
an in-place upgrade

- Run the in-place upgrade (should install new package and create 
/etc/nsm/HOSTNAME-INTERFACE/bpf.conf):
sudo -i "curl -L 
http://sourceforge.net/projects/security-onion/files/20120329/security-onion-upg
rade.sh > ~/security-onion-upgrade.sh && bash ~/security-onion-upgrade.sh"

- Add a BPF to /etc/nsm/HOSTNAME-INTERFACE/bpf.conf like the following (for 
testmyids.com):
not host 217.160.51.31

- Run "sudo nsm_sensor_ps-restart" to restart Snort and daemonlogger

- Verify that snort doesn't alert on "curl http://testmyids.com" anymore and 
that daemonlogger didn't record any packets for that destination

- run Setup to simulate a new install

- Run the same test as above.

- Verify issues 224, 242, and 243 are fixed as well

- Anything else I didn't think of


Thanks in advance for your time and effort!
