tcpdump: socket: address family not supported by protocol 错误解析与解决 1. 错误信息含义 错误信息 "tcpdump: socket: address family not supported by protocol" 表示 tcpdump 在尝试创建一个套接字时,遇到了一个不被当前协议支持的地址族。这通常意味着 tcpdump 试图在不兼容的网络接口或环境下运行。 2...
root@linux#tcpdump -n tcp port 22tcpdump: socket: Address family not supported by protocol The cause Theaf_packetkernel module is not loaded. This implements raw sockets, with which one can access a network card directly, bypassing TCP/IP – and this module is exactly whattcpdumpneeds. ...

In addition, the sockets API provides the data typestruct sockaddr_storage. This type is suitable to accommodate all supported domain-specific socket address structures; it is large enough and is aligned properly. (In particular, it is large enough to hold IPv6 socket addresses.) The structure ...
pt_prev = ptype; } } 四、向传输层的dispatch 网络层协议的注册通过net_protocol对象来注册,在af_inet.c文件中定义了我们最为常见的igmp_protocol、tcp_protocol、udp_protocol、icmp_protocol。这些协议注册之后,在IP层向上dispatch的时候就可以直接使用这个作为路由规则(或者认为是protocol selector,我更prefer这个...

若要使用 UDP 而不是 TCP,需要更改协议类型,如下面的示例所示: Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); 一旦创建 Socket,在客户端,你将可以通过Connect方法连接到指定的服务器,并通过Send/SendTo方法向远程服务器发送数据,而后可以通过Receive/ReceiveFrom从服务端接...
查看了 docker log, 发现了一个 ``dial tcp 127.0.0.1:8202: socket: too many open files 的问题, 但是请求的 http server 也是布署在同一台服务器上, 它们也共享了同一个 docker network, 通常是 不会出现这个问题的, 之后就猜到可能是因为本地的 TCP 端口号被占完了, 或者分配给该进程 的文件句柄数...
