Type = 68, Length = 8, Pointer = 5, oflw = 0, flag = 0, timestamp = 32 bits of zeros. The respons is a echo reply (correct) but with the overflow flag set to 1 (incorrect) and no timestamp supplied. Using flag = 1 or 3 gives the correct response. >How-To-Repeat: Create a IP packet with timestamp option (see above) + Icmp echo request and send it to the FreeBSD host/router. Check the timestamp option in the reply. The overflow flag is set but it should not. >Fix: I guess timestamp with only timestamp is not implemented. It seems like timestamp with timestamp + IP address is only implemented. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
