Disallow leading lines before the ident for server (#102) Per RFC4253 4.2 clients must be able to process other lines of data before the version string, server behavior is not defined neither with MUST/SHOULD nor with MAY. If server process up to 50 lines too - it may cause too long hanging session with invalid/evil client that consume host resources and potentially may lead to DDoS on poor embedded boxes. Let's require first line from client to be version string and fail early if it's not - matches both RFC and real OpenSSH behavior.

 * This is really the combination of two SBoxes; the least significant

 * "On the Design of 8*32 S-boxes". Unpublished report, by the
 * Information Systems Research Centre,
 * Queensland University of Technology, 1999.
 * 
 * The most significant 8 bits are the Skipjack "F table", which can be
 * found at http://csrc.nist.gov/CryptoToolkit/skipjack/skipjack.pdf .
 * In this optimised table, though, the intent is to XOR the word from
 * the table selected by the high byte with the input word. Thus, the
 * high byte is actually the Skipjack F-table entry XORED with its
 * table index.
