contains a few bits for reference into a table of MSS values; window size and any initial data is discarded; and the rest of the ISS is the MD5 output
It will also break T/TCP I think. While it is not a big issue at the moment it may become a real one later. Stevens in his thirs volume describe why T/TCP is a good thing and it will be seen more and more in the future. In FreeBSD-current, there is a fix too for the SYN attack. I don't remember the details of what has been done but the source code is of course available. -- Ollivier ROBERT -=- Eurocontrol EEC/TS -=- Ollivier.Robert () eurocontrol fr
