SCO TCP/IP network management --- start of TCP/IP

I have written this article about the management of SCO TCP/IP. I hope it will be helpful to you, just like what was written at the beginning of this topic, this is the basis for hackers, and we still need to discuss it in the direction of network management! Haha!1 TCP/IP s

the subnet mask, Gateway is the next hop address, iface is the sending interface, and the U mark in flags indicates that the entry is valid (some entries can be disabled ), the G flag indicates that the next hop address of this route entry is the address of a vro, And the entry without the G flag indicates that the destination network address is a network directly connected to the local interface and does

a host or a simple routing algorithm for it. essentially the difference is that the host never forwards the datagram from one interface to another, while the router forwards the datagram. The host that contains the router function should never forward datagrams unless it is set to that.In a general system, IP can accept datagrams from tcp,udp,icmp and IGMP (i.e. locally generated datagrams) and send them,

Talk about sockets, TCP/IP, HTTP, FTP, and network programming __socket

an application layer protocol, and its transmission is packaged into TCP protocol transmission. HTTP can be implemented with a socket. A socket is a programming API that implements the Transport layer protocol, either TCP or UDP. "Applicable Situation" If the two sides establish an HTTP connection, the server needs to wait until the client sends a request before the data can be passed back to the client, s

When we learn and use the Android network programming, we touch only the upper layer protocols and interfaces such as Apache HttpClient or Android's own httpurlconnection and so on. We also need to learn more about the underlying implementations of these interfaces, which requires that we understand the network communication layer and that the network communicati
