Hi Monks

i have a dhcp server which gives ip to the customers..now as soon as the lease is created i want to put that lease details into database...

#!/usr/bin/perl 
use POSIX qw(strftime);
use File::Copy;
#use strict;
use Fcntl qw(:flock);

open(my $script_fh, '<', $0)
   or die("Unable to open script source: $!\n");

unless (flock($script_fh, LOCK_EX|LOCK_NB)) {
    print "$0 is already running. Exiting.\n";
    exit(1);
}

copy("/var/lib/dhcp3/dhcpd.leases","presentfile") or die "Copy failed:
+ $!" ;

#open (STDERR,">","dhcp_err");
open (LEASE, ">","leftleases");
open (FILE,"<","prevfile");
open (MYFILE,"presentfile");
open (SFILE,">","dhcp.sql");

 $line1 = <MYFILE>;
 @cnt_file = <FILE>;
 $cnt = @cnt_file;

while ($line1 ne ""){
$line1 = <MYFILE>;
print LEASE "$line1" if ($. > $cnt);
}

open(LEASE, "<","leftleases");

foreach my $line (<LEASE>) {
chomp($line);
if ($line =~ /^lease/) {
 $ip = (split(" ", $line))[1];
}
if ($line =~ /^  starts/) {
 ($sdate, $stime) = (split(" ", $line))[2,3];
}
if ($line =~ /^  ends/) {
 ($edate, $etime) = (split(" ", $line))[2,3];
}
if ($line =~ /^  hardware ethernet/) {
 $mac = (split(" ", $line))[2];
$mac =~ s/;//;
}
if ($line =~ /^  client-hostname/) {
 $client = (split(/\"/, $line))[1];
}
if ($line =~ /^  binding state/) {
 $binding_state  = (split(" ", $line))[2];
$binding_state  =~ s/;//;
}
if ($line =~ /^  next binding state/) {
 $next_binding_state = (split(" ", $line))[3];
$next_binding_state  =~ s/;//;
}
if ($line =~ /^}/) {
print SFILE ("INSERT INTO dhcp_leases \(start_date,start_time,end_date
+,end_time,ip_address,mac_address,binding_state,next_binding_state,cli
+ent_hostname\)VALUES\(\'$sdate\',\'$stime\',\'$edate\',\'$etime\',\'$

$ip = ""; $sdate = ""; $stime = ""; $edate = ""; $etime = ""; $mac = "

}
}

close(LEASE);
unlink("prevfile");
copy("presentfile","prevfile");
open(FILE,"<","$path/log/dhcp.sql");
my @host=<FILE>;
chomp(@host);
foreach my $host(@host)
{
my $driver = "mysql"; 
my $database = "dhcp";
my $dsn = "DBI:$driver:database=$database";
my $userid = "root";
my $password = 'password';

my $dbh = DBI->connect($dsn, $userid, $password ) or die $DBI::errstr;

my $sth = $dbh->prepare("$host");
$sth->execute() or die $DBI::errstr;
$sth->finish();
