We cant just guess what you put in it... Show us the code and the output and we can help get it working...
Actually I tried this below program which is in the correct sequence order of 16 client ip address from 192.168.1.3 to 192.168.1.19.But I questioned program I don't have an idea because it is not in the correct sequence order of ip address.I just want to ping from server to 16 client ip address.whether the connection is available or not. I'm expecting output like as,
*How many connections are available and list that ips.
*How many connections are not available and list that ips.

My tried program code:
Code:
#!/bin/bash

upcnt=0
downcnt=0
for ip in 192.168.1.{3..19}
do
   if ping -c 1 -W 1 $ip > /dev/null
   then
        let upcnt=upcnt+1
        uplist="$uplist\n    $ip"
   else
        let downcnt=downcnt+1
        downlist="$downlist\n    $ip"
   fi
done

printf "$upcnt ips are available:$uplist\n"
printf "$downcnt ips are not available:$downlist\n"

Please If you have an idea , Please give me a shell script for my questioned program.

adsl-connect

ADSL-CONNECT(8) 					      System Manager's Manual						   ADSL-CONNECT(8)

NAME

       adsl-connect - Shell script to manage a PPPoE link

SYNOPSIS

       adsl-connect [config_file]

       adsl-connect interface user [config_file]

DESCRIPTION

       adsl-connect  is  a  shell  script  which  manages  an ADSL connection using the Roaring Penguin user-space PPPoE client.  If you omit con-
       fig_file, the default file /etc/sysconfig/network-scripts/ifcfg-ppp0 is used.  If you supply interface and user,  then  they  override  the
       Ethernet interface and user-name settings in the configuration file.

       Note that normally, you should not invoke adsl-connect directly.  Instead, use adsl-start to bring up the ADSL connection.

       adsl-connect first reads a configuration file.  It then brings up a PPPoE connection.  If the connection ever drops, a message is logged to
       syslog, and adsl-connect re-establishes the connection.	In addition, each time the connection is dropped or cannot be  established,  adsl-
       connect executes the script /etc/ppp/adsl-lost if it exists and is executable.

       The shell script adsl-stop causes adsl-connect to break out of its loop, bring the connection down, and exit.

TECHNICAL DETAILS

       adsl-connect uses the following shell variables from the configuration file:

       ETH    The Ethernet interface connected to the ADSL modem (for example, eth0).

       USER   The ADSL user-id (for example, b1xxnxnx@sympatico.ca).

       PIDFILE
	      A  file in which to write the process-ID of the adsl-connect process (for example, /var/run/pppoe.pid).  Two additional files ($PID-
	      FILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the pppd and pppoe processes, respectively.

       By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections.  Just specify  the  con-
       figuration file as an argument to adsl-start and adsl-stop.

       adsl-connect was written by David F. Skoll <dfs@roaringpenguin.com>.
