Hello everyone!
I am trying to create a dns packet, using pack/unpack function. but i encountered a problem, and the problem is that i can't pack the query part of the packet,here is its code:
$hostname=$ARGV[0];
$counter=0;
##formate of each label.
for (split(/\./,$hostname)){
$label[$counter++] = length;
$label[$counter++] = $_;
$lformat .= "C a* ";
}
print "\n@label\n";
$question = pack($lformat."C n2",@labels,0,1,1);
any one's help is appreciated, thank u
