Transport endpoint is not connected问题的解决！

我用Vmware装了个linux,用socket去connect我windows的一个通信server程序
connect没有报错,但recv和send都出错,说Transport endpoint is not connected之类的
但从代码可以看出,connect没有报错
代码是这样的,非常简单,希望高手指点.

#include

#define PORT 56790
#define MAXDATASIZE 1024

int sockfd;
pthread_t recthread;

void recmessage()
{
while(1)
{
int numbytes;
char buf[MAXDATASIZE];

if((numbytes=recv(sockfd,buf,MAXDATASIZE,0))==-1)
{
perror( "recv...... ");
exit(1);
}

buf[numbytes]= '\0 ';
if(strcmp(buf, "exit ")==0)
{
printf( "Server is closed.\n ");
close(sockfd);
exit(1);
}
printf( "Server :%s.\n ",buf);
}
}

int main()
{
struct hostent *he;
struct sockaddr_in their_addr;
if((sockfd=socket(AF_INET,SOCK_STREAM,0))==-1)
{
perror( "socket ");
exit(1);
}
their_addr.sin_family=AF_INET;
bzero(&their_addr,sizeof(their_addr));

their_addr.sin_port=htons(PORT);
their_addr.sin_addr.s_addr=inet_addr( "192.168.1.77 ");


bzero(&(their_addr.sin_zero),8);
if(connect(sockfd,(struct sockaddr*)&their_addr,sizeof(struct sockaddr))==-1)
{
perror( "connect ");
exit(1);
}
sleep(1);
printf( "socket id is %d ",sockfd);


if((pthread_create(&recthread,NULL,(void *)recmessage,NULL))!=0)
{
printf( "Create thread error!\n ");
exit(1);
}

while(1)
{
char msg[MAXDATASIZE];
scanf( "%s ",msg);
if(send(sockfd,msg,strlen(msg),0)==-1)
{
perror( "send ");
close(sockfd);
exit(1);
}
if(strcmp(msg, "exit ")==0)
{
printf( "Byebye!\n ");
close(sockfd);
exit(1);
}
}
return 0;
}

<网友回复> their_addr.sin_family=AF_INET;
bzero(&their_addr,sizeof(their_addr));

their_addr.sin_port=htons(PORT);
their_addr.sin_addr.s_addr=inet_addr( "192.168.1.77 ");


bzero(&(their_addr.sin_zero),8);
=============
试试改为：
bzero(&their_addr,sizeof(their_addr));
their_addr.sin_family=AF_INET;
their_addr.sin_port=htons(PORT);
their_addr.sin_addr.s_addr=inet_addr( "192.168.1.77 ");

<网友回复>非常感谢,刚从windows的通讯转linux的,我一直以为是平台的搭建

原来犯下低级的逻辑错误,谢谢了
