running: 2.6.3-4mdk using a socket(AF_INET, SOCK_RAW, IPPROTO_TCP), I send a SYN to host A I get back SYN, ACK. then, despite the fact that the socket is RAW the kernel sends out a RST to host A. the problem doesn't seem to exist on another machine running 2.6.5. this seems like an issue with the kernel as opposed to some C library, but let me know if it isn't. otherwise any comments would be appreciated. patrick schless - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
