Hi, I'm using FreeBSD-2.2.6. I'm running a TCP transfer between two machines - one machine has T/TCP turned off while the other doesn't. (I turned T/TCP off using command "sysctl -w net.inet.tcp.rfc1644=0"). The problem is that even though the machine that has T/TCP turned off doesn't send any T/TCP specific options, it still receives these options in non-SYN segments from the other machine. Moreover, it still processes the T/TCP specific options sent by the other machine. In a nutshell there are two problems: 1) The machine where T/TCP is enabled shouldn't be sending T/TCP specific options in segments other than the initial SYN segment as the corresponding SYN from the other end didn't contain any such options. 2) Even when T/TCP options are received on the machine where T/TCP is disabled, it should ignore them. - Mohit To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
