Linux windows socket 连接问题

来源: 互联网发布时间：2016-08-13

本文导语: 总是连接不上, 现在想windows做服务器（C#.net 2.0)写的。 Linux做客户端。连接时提示 connection refused windos 连接linux时提示目标机拒绝。防火墙什么的都关掉了，ping都能通。请朋友们帮我看。 windows 服务器 C# ...

总是连接不上,
现在想windows做服务器（C#.net 2.0)写的。
Linux做客户端。连接时提示 connection refused
windos 连接linux时提示目标机拒绝。
防火墙什么的都关掉了，ping都能通。

请朋友们帮我看。

windows 服务器 C# 代码如下

using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Sockets;
using System.Net;

namespace TestTools.SocketServer
{
    public class SocketServer
    {
        private Socket _Server;
        private IPAddress _IP;
        private IPEndPoint _IPE;
        private int _Port = 6630;
        protected Encoding encoding = Encoding.GetEncoding("GB2312");
        private Socket _temp;
        public SocketServer()
        {
            Create();
        }
        private void Create()
        {
            if (null == _Server)
            {
                _Server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                _IP = GetServerIP();
                _IPE = new IPEndPoint(_IP, _Port);
                _Server.Bind(_IPE);
            }
        }
        public static IPAddress GetServerIP()
        {
            IPHostEntry ieh = Dns.GetHostEntry(Dns.GetHostName());
            return ieh.AddressList[0];
        }
        public void Start()
        {
            Create();
            _Server.Listen(0);

            _temp = _Server.Accept();//为新建连接创建新的Socket。
            Console.WriteLine("Connected.");

        }
        public void Receive()
        {
                string recvStr = "";
                byte[] recvBytes = new byte[1024];
                int bytes;
                bytes = _temp.Receive(recvBytes, recvBytes.Length, 0);
                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);

                Console.WriteLine("Server Get Message:{0}", recvStr);

        }
        public void Send(string data)
        {
            byte[] bs = Encoding.ASCII.GetBytes(data);
            _temp.Send(bs, bs.Length, 0);//发送测试信息
        }
        public void Disconnect()
        {
            _Server.Shutdown(SocketShutdown.Both);
            _Server.Disconnect(true);
        }
        public bool isConnect()
        {
            Create();
            return _Server.Connected;
        }

        internal void Close()
        {
            _Server.Close();
        }
    }
}

Linux c 客户端代码如下

#include "./head.h"

main()
{
int sockfd;
int len;
struct sockaddr_in address;
int result;
int i,byte;
char char_recv,char_send;
if((sockfd = socket(AF_INET,SOCK_STREAM,0))==-1)
{
perror("socket");
exit(EXIT_FAILURE);
}
address.sin_family = AF_INET;
address.sin_addr.s_addr = inet_addr("192.168.1.103");
address.sin_port = 6630;
len = sizeof(address);
if((result = connect(sockfd,(struct sockaddr*)&address,len))==-1)
{
perror("connect");
exit(EXIT_FAILURE);
}
sleep(1);
char ss[222];

struct msg message;
