Most probably the variable contains a newline or some other
whitespace character like this. Try to print it out with
print ">$servidor<\n";
Does that look right?
Maybe you'll have to chomp($servidor) or
$servidor =~ s/\s+$//;
or whatever. If you want to be sure what character is it try this:
$hex = unpack('H*', $servidor);
$hex =~ s/(..)/$1 /g;
print $hex;
