This might be of some use to people:

<ENDSCRIPT>

FQNAME=`echo $FQNAME | tr '[A-Z]' '[a-z]'`

case $1 in

        su - itsysmon -c "/path/to/hobbit/client/runclient.sh --hostname=${FQNAME} start"
        ;;

        su - itsysmon -c "/path/to/hobbit/client/runclient.sh --hostname=${FQNAME} stop"
        pkill hobbitlaunch
        pkill vmstat
        pkill iostat
        ;;
'restart')
        $0 stop
        $0 start
        ;;

        echo "usage: $0 {start|stop|restart}"
        ;;
esac

<ENDSCRIPT>

You should obviously replace your domain name (if required at all) and your install path..

I had to add the lines:
pkill hobbitlaunch
pkill vmstat
pkill iostat

As I found that they were not always stopped cleanly..

To add it to automatically restart

#chkconfig --add xymon
#chkconfig --level 5 xymon on

Thanks everyone for your suggestions.  Adding the hostname to the startup script works nicely.

I didn't include it in my original posting, but the host name was included in the /etc/hosts file.  I tried changing the order of the entries in the hosts file, but that didn't seem to affect anything.   The box was configured in the hobbit's server's bb-hosts file.

Cathy, 

When you start the client, runclient.sh will get the client name from the MACHINEDOTS="`uname -n`"  var.  As Ryan mentioned, perhaps you don't have a hostname / ip configured in /etc/hosts on the RHEL5 box.

Whatever the output of hostname is (from the RHEL5 box) should have a matched entry in rhel5:/etc/hosts that is not localhost.

You can cheat and define your own hostname in runclient.sh but it would be better to stick with the standard setup and properly configure the RHEL5 client AND the server.  The server expects to see the same hostname defined in bb-hosts as reported by the client's `hostname`/$MACHINDOTS var.

Hope that makes some sense...

Regards, 

Tim

Yes, that is true, but the client should not be reporting 127.0.0.1 as
its IP address either. Maybe the RHEL5 client has no hostname with a
valid IP in its /etc/hosts, or the hostname is listed on the 127.0.0.1 line.
