A lot of times, Util.longForName is referenced in the packets following:
<pre>
public static long longForName(String arg0) {
		String s = "";
		for (int i = 0; i < arg0.length(); i++) {
			char c = arg0.charAt(i);
			if (c >= 'a' && c <= 'z')
				s = s + c;
			else if (c >= 'A' && c <= 'Z')
				s = s + (char) ((c + 97) - 65);
			else if (c >= '0' && c <= '9')
				s = s + c;
			else
				s = s + ' ';
		}

		s = s.trim();
		if (s.length() > 12)
			s = s.substring(0, 12);
		long l = 0L;
		for (int j = 0; j < s.length(); j++) {
			char c1 = s.charAt(j);
			l *= 37L;
			if (c1 >= 'a' && c1 <= 'z')
				l += (1 + c1) - 97;
			else if (c1 >= '0' && c1 <= '9')
				l += (27 + c1) - 48;
		}

		return l;
