Much delayed but now present: RFC 1948 style sequence numbers

2001-08-22T00:59:13+00:00

In order to ensure security and functionality, RFC 1948 style
initial sequence number generation has been implemented.  Barring
any major crypographic breakthroughs, this algorithm should be
unbreakable.  In addition, the problems with TIME_WAIT recycling
which affect our currently used algorithm are not present.

2001-06-12T16:15:07+00:00

Disable rfc1323 and rfc1644 TCP extensions if we havn't got
any response to our third SYN to work-around some broken
terminal servers (most of which have hopefully been retired)
that have bad VJ header compression code which trashes TCP
segments containing unknown-to-them TCP options.
