I want to add ip options when the IP packet send out. I have read the rfc 971 about the format of the ip_options, then I set the IP_options using setsockopt. when the program running in Linux, it works. But when I complied in vc 6.0 in Windows 2000 professional plarform, it does work. I use getsockopt and find the ip_options have been added, but when I catch the IP packet using sniffer and see no ip options. why, how can I send a packet bringing with a ip options of mine through stream socket.(you know, using a raw socket, I can add the Ip options, but the tcp/ip stack can not be used. )
