    I have been having a a problem recently with a script set to SSH into
    a snort sensor and stop-snort--->retrieve logs--->delete logs. I have
    four sensors three of which are running Redhat 7.2. The 7.2 sensors
    are running openssh 2.9p2. We have been running one sensor on Redhat
    8.0 openssh version 3.1p1. When the script is executed everything
    terminates properly except the Redhat 8.0 sensor. After we run the
    script there is still an ssh process on the client and on the sensor
    itself the daemon process has not terminated. The script executes fine
    but at the end of the day I have 60+ orphaned processes. I have read
    miscellanous information about this problem being a feature...not a
    bug. I will include the portion of the script below. Can anyone help
    me handle this better? I have tried many little fixes such as shopt -s
    huponexit etc...
    Thanks very much.

    echo "Removing Log files from Sensor 1 and Sensor 2"
    ssh idssensor1.null.com rm -f /var/snort/sensor1/snort0.log
    /var/snort/sensor1/portscan0.log /var/snort/sensor2/snort0.log
    /var/snort/sensor2/portscan0.log < /dev/null >& /dev/null &
    echo "Done...."
    echo "Removing Log files from Sensor 3"
    ssh idssensor2.null.com rm -f /var/snort/sensor3/snort0.log
    /var/snort/sensor3/portscan0.log < /dev/null >& /dev/null &
    echo "Done...."
    echo "Removing Log files from Sensor 4 and Sensor 5"
    ssh idssensor4.null.com rm -f /var/snort/sensor4/snort0.log
    /var/snort/sensor4/portscan0.log /var/snort/sensor5/snort0.log
    /var/snort/sensor5/portscan0.log < /dev/null >& /dev/null &
    echo "Done...."

    When I do a ps -ef

    below is the result.

    root 1392 1391 0 09:22 tty1 00:00:00 -bash
    root 1627 1 0 09:45 ? 00:00:00 ssh
    idssensor4.null.com rm -f /var/snort/sensor4/snort0.log
    /var/snort/sens
    root 1760 628 0 10:11 ? 00:00:00 /usr/sbin/sshd
    root 1761 1760 0 10:11 pts/0 00:00:00 -bash
    root 1816 1761 0 10:13 pts/0 00:00:00 ps -ef
