这个是Linux的TCP结构：
/* Structure of a TCP header */
struct tcp {
unsigned short tcp_source_port;
unsigned short tcp_dest_port;
unsigned int tcp_seqno;
unsigned int tcp_ackno;
unsigned int tcp_res1:4, /*little-endian*/
tcp_hlen:4,
tcp_fin:1,
tcp_syn:1,
tcp_rst:1,
tcp_psh:1,
tcp_ack:1,
tcp_urg:1,
tcp_res2:2;
unsigned short tcp_winsize;
unsigned short tcp_cksum;
unsigned short tcp_urgent;
};
我是ROOT用户，也做了更改，以下是出错信息：

其实网络编程我只是有兴趣，我不是专职程序员。个人也通读过W.Richard Stevens的TCP/IP三卷中的卷一，不过没有多少实践经验。只不过在编译时，一看到这么多问题，再加上最近实在太忙，所以就懒的理了。。。
昨天一个同事离开，喝了点酒，跳舞，脑子倒现在还混沌沌的，等我清醒一点再继续说，今天上班看来要打瞌睡了。。。作者: stenphen 时间: 2002-4-27 17:03
打搅两位的讨论了，我想请帮个忙，是我朋友的，再liunx下装网卡驱动的时候出现的问题。redhat7.1
