Your options: 1. Get Xylogics fix their TCP stack (preferred ;-). 2. Disable tcp_extensions in /etc/sysconfig. Actually, it's enough to do `sysctl -w net.inet.tcp.rfc1644=0' if you don't want to lose the other TCP extensions. Andras P.S: You can look up the T/TCP homepage for information about T/TCP including a list of TCP stacks having problem with T/TCP. http://www.noao.edu/~rstevens/ttcp.html
