Subject: Script Required to Check a range of IP's

Hi Folks,


Howdy,

I have a requirement of writing down a script to check the range of
IP's
in
a text file and display them which all are active and not active.

I have written down the below and needs your help because it is not
giving
me the correct ouptut.

################################################################
#!/usr/bin/perl

use strict;
use warnings;
use Net::Ping;

my $file_name=$ARGV[0];
my $line;
my @host_array;

open(FILE,"$file_name") || die "Not been Accessed";

To be of more help, I'd suggest that you provide some example input. Is
there one address per line? Multiple addresses per line (delimited).


while (<FILE>) {
chomp;
@host_array=$_;
}


If we have some example input, then we can tell if the 'while' block is
kosher. If there are multiple IP addresses, then you'll want to 'push'
the addresses into @host_array.

ry

my $p = Net::Ping->new();
foreach my $host (@host_array)
{
print "$host is ";
print "NOT " unless $p->ping($host, 2);
print "reachable.\n";
sleep(1);
}
$p->close();

close (FILE);

Needs your help on the above
