一个网络编程方面的有关问题，connect（）老是报错，请高手帮忙

一个网络编程方面的问题，connect（）老是报错，请高手帮忙！
客户端程序每次都提示下面的错误，不知道是什么原因：
-> socket_client
addr: 192.168.10.34
create socket OK!!!!!!!
: OK
connect error: S_errno_EHOSTUNREACH
value = -1 = 0xffffffff

下面是客户端的代码：
#include <vxWorks.h>
#include <string.h>
#include <errnoLib.h>
#include <netdb.h>
#include <netinet/in.h>
#include <sockLib.h>
#include <ioLib.h>
#include <stdio.h>
#include <hostLib.h>
#include <inet.h>

#define port_num 6100

int socket_client()
{
int sockAddrSize; /* size of socket address structure */
int clientsocket;  
struct sockaddr_in serversocket;/* connector's address information */
char buf[200];
int numbytes;
struct hostent *he;
char *server = "192.168.10.34";

sockAddrSize = sizeof (struct sockaddr_in);
bzero ((char *) &serversocket, sockAddrSize);
serversocket.sin_family = AF_INET; /* host byte order */ 
serversocket.sin_port = htons(port_num); /* short, network byte order */ 
serversocket.sin_len = (u_char) sockAddrSize;
serversocket.sin_addr.s_addr = inet_addr(server);
bzero((char *)&(serversocket.sin_zero),8);

printf("addr: %s\n",inet_ntoa(serversocket.sin_addr));

if((clientsocket = socket(AF_INET,SOCK_STREAM,0))==ERROR)
{
perror("create socket error\n");
return(ERROR);
}
perror("create socket OK!!!!!!!\n");

if((connect(clientsocket,(struct sockaddr*)&serversocket,sockAddrSize))==ERROR)
{
perror("connect error");
return(ERROR);
}
perror("connect OK\n");

if((numbytes = recv(clientsocket, buf,200,0)))
{
perror("recv error");
return(ERROR);
}
perror("ALL OK!!!!");

buf[numbytes]='\0';
printf("Received: %s",buf);
close(clientsocket);
return 0;
}


下面是服务器端的代码：
#include <vxWorks.h>
#include <string.h>
#include <errnoLib.h>
#include <netdb.h>
#include <netinet/in.h>
#include <sockLib.h>
#include <ioLib.h>
#include <stdio.h>
#include <inet.h>

#define port_num 6100
/*#define Client_IP "192.168.10.34"*/
int socket_service()
{
struct sockaddr_in serverAddr; /* server's socket address */
struct sockaddr_in clientAddr; /* client's socket address */
int sockAddrSize; /* size of socket address structure */
int mysocket; /* socket file descriptor */
int sClientSocket;

/* set up the local address */
sockAddrSize = sizeof (struct sockaddr_in);
bzero ((char *) &serverAddr, sockAddrSize);
serverAddr.sin_family = AF_INET;
serverAddr.sin_len = (u_char) sockAddrSize;
serverAddr.sin_port = htons (port_num);
serverAddr.sin_addr.s_addr = htonl (INADDR_ANY);

/*CREATE a socket*/

if((mysocket = socket(AF_INET,SOCK_STREAM,0))==ERROR)
{
perror("create socket error\n");
return(ERROR);
}
perror("create socket OK!!!!!!!!\n");

/*bind socket to server address*/

if(bind(mysocket,(struct sockaddr*)&serverAddr,sockAddrSize) == ERROR)
{
perror("bind error\n");
close(mysocket);
return(ERROR);
}

perror("bind OK!!!!!!!!!\n");

/*listen */
if(listen(mysocket,5) == ERROR)
{
perror("ERROR\n");
return(ERROR);
}
perror("LISTEN OK!!!!\n");

/*ACCEPT() wait for new client connection */
while(1)
{
sockAddrSize = sizeof (struct sockaddr_in);
if((sClientSocket==accept(mysocket,(struct sockaddr *) &clientAddr, &sockAddrSize))==ERROR)
