Hello FishMonger and Laurent,
Here is the code to delete an ip address. Similarly i want to write different subroutines to GROW and SHRINK and COMBINE subnets.
I would request you to please let me know, on which subroutine should i first start my work. GROW,SHRINK,OR COMBINE.
If you have suggestions, please provide me.
sub remove_address
{
$BLOCK=new2 Net::Netmask("$ADDRESS");
if ( ! defined($BLOCK) )
{
print_error("Bad Address: $ADDRESS");
print_error("END");
return();
}
$OK=0;
$SQL="select ip, devicename from cpe_device_copy where shortname = '$CUSTOMER'";
$STH=$DBH->prepare($SQL);
$STH->execute();
sql_check();
while ( @ROW=$STH->fetchrow_array() )
{
if ( $BLOCK->match($ROW[0]) )
{
print_error("Device $ROW[0] $ROW[1] is using the range you wish to remove");
$OK++;
}
}
if ( $OK )
{
print_error("END");
return;
}
$SQL="select address from customer_address_copy where shortname = '$CUSTOMER'";
$STH=$DBH->prepare($SQL);
$STH->execute();
sql_check();
undef($R);
while ( @ROW=$STH->fetchrow_array() )
{
$T=new2 Net::Netmask("$ROW[0]");
if ( $T->match($BLOCK->base()) && $T->bits()<=$BLOCK->bits() )
{
print_error(sprintf("Remove ajay %s From $ROW[0]",$BLOCK->desc()));
if ( defined($R) )
{
print_error("Error: More than one block matches");
print_error("END");
return();
}
$R=$ROW[0];
}
}
if ( ! defined($R) )
{
print_error("ERROR: No Blocks Match");
print_error("END");
return();
}
$RBLOCK=new2 Net::Netmask("$R");
$BITS=$BLOCK->bits();
foreach $IP ( $RBLOCK->enumerate($BITS) )
{
$LIST{$IP}=1;
}
$LIST{$BLOCK->base()}=0;
foreach $IP ( keys(%LIST) )
{
next if ( $LIST{$IP}==0 );
$BLOCKS[$#BLOCKS+1]=new Net::Netmask("$IP/$BITS");
}
$LASTUPDATE=`date`;
chomp($LASTUPDATE);
$LASTUPDATE="$USERNAME: $LASTUPDATE";
foreach $BLOCK ( cidrs2cidrs(@BLOCKS) )
{
print_error(sprintf("INFO: Add %s<br>\n",$BLOCK->desc()));
$SQL=sprintf("insert into customer_address_copy ( shortname, address, lastupdate ) values ( '$CUSTOMER','%s','$LASTUPDATE' )",$BLOCK->desc());
$DBH->do($SQL);
sql_check();
}
print_error(sprintf("Remove Ajay %s<br>\n",$RBLOCK->desc()));
$SQL=sprintf("delete from customer_address_copy where shortname='$CUSTOMER' and address='%s'",$RBLOCK->desc());
#printf("$SQL");
$DBH->do($SQL);
sql_check();
print_error("END");
}
