Hello! Today I have noticed strange behaviour of TCP in Linux. We send SYN packet with DSCP=63 to Linux server. If there is no firewall, server will respond with one of two possible packets: 1) If port is open, it will send us SYN,ACK with DSCP=0 2) If port is closed, it will respond with RST,ACK DSCP=63. The question is: why DSCP of RST,ACK packet is set to DSCP value of SYN packet? My kernel is 2.6.14. Didn't try with latest kernel yet. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
