When i load the kld ,the code try to connect the server of ftp,but i foud the code does not work right . the function , connect ,which return is right ,but ,when i see the status of connection by "netstat -a" , i found the connection didn't establish! the detailed code is attached the following code have mistake!! The platform is freebsd 5.3 /* create socket */ td=curthread; sock.domain = AF_INET; sock.type = SOCK_STREAM; sock.protocol = 0; st = socket(td, &sock); /* does create ok? */ if( st != 0 ) { /* create error */ log(LOG_DEBUG,"create socket error!\n"); goto main_shutdown; } printf("the fd of socket is%d\n",control_fd); /* has create one ok socket */ printf("the socket is created!"); ///////////////////////////////////////////////////////////////// there are some mistake here!!!! /*connect*/ bzero(&sa_in, sizeof sa_in); sa_in.sin_family = AF_INET; /*this is port of ftp*/ sa_in.sin_port = htons(21); /*this is my computer ip:172.19.11.8*/ sa_in.sin_addr.s_addr = htonl((((((172 << 8) | 19) << 8) | 11) << 8) | 48); conn.s=control_fd ; conn.name=(char*) &sa_in; conn.namelen=sizeof(sa_in); /*why do not i connect the server of ftp*/ nError=connect(td,&conn); if (!nError){ printf("connect failed!"); goto main_shutdown; } ; printf("connect is secusess!"); --------------------------------- DO YOU YAHOO!? 雅虎免费G邮箱－中国第一绝无垃圾邮件骚扰超大邮箱 --0-633563741-1117526259=:38258--
