Hi every body..........

I am working on Linux redhat 9,two machines running tcpserver and tcpclient programmes,I need to send about "50000" Byte of integers, the server sends them well,but the client recieves about "12287" Byte well,but it recieves the rest of numbers zeroes!!!!!!!!!!!!!!!!!,Inever understood that.
any help will be appresiated.

How do you know the server is sending them correctly? Some code would be helpful.

Hi....
to be sure that the server snds them correctly I use "printf", here is the code:
/* server.c */

#include<sys/types.h>
#include<sys/socket.h>
#include<netinet/in.h>
#include<unistd.h>
#include<stdlib.h>
#include<stdio.h>
#include<time.h>
#include<sys/time.h>
#include<stddef.h>
#include<math.h>
void main()
{
int cont,create_socket,new_socket,addrlen;
int bufsize = 50000;
int *buffer = malloc(bufsize);
struct sockaddr_in address;




printf("\x1B[2J");
if ((create_socket = socket(AF_INET,SOCK_STREAM,0)) > 0)
printf("The socket was created\n");
address.sin_family = AF_INET;
address.sin_addr.s_addr = INADDR_ANY;
address.sin_port = htons(15000);
if (bind(create_socket,(struct sockaddr *)&address,sizeof(address)) == 0)
printf("Binding Socket\n");
listen(create_socket,6);
addrlen = sizeof(struct sockaddr_in);
new_socket = accept(create_socket,(struct sockaddr *)&address,&addrlen);
if (new_socket > 0){
printf("The Client %s is connected...\n",inet_ntoa(address.sin_addr));
for(cont=1;cont<5000;cont++)
printf("\x7");
}

int i,g=0,j,u,t=0,y,d=0,q,k;


for(i=0;i<bufsize;i++)
buffer[i]=5;

send(create_socket,buffer,bufsize,0);

for(i=0;i<bufsize;i++)
ptintf("buffer[%d]=%d",i,buffer[i]); //To be sure the buffer is not empty.

close(new_socket);
close(create_socket);
}





/* client.c */

#include<sys/socket.h>
#include<sys/types.h>
#include<netinet/in.h>
#include<unistd.h>
#include<stdlib.h>
#include<stdio.h>

main(int argc,char *argv[])
{
int create_socket;
int bufsize = 50000;
int *buffer = malloc(bufsize);
struct sockaddr_in address;

printf("\x1B[2J");
if ((create_socket = socket(AF_INET,SOCK_STREAM,0)) > 0)
printf("The Socket was created\n");
address.sin_family = AF_INET;
address.sin_port = htons(15000);
inet_pton(AF_INET,argv[1],&address.sin_addr);

if (connect(create_socket,(struct sockaddr *)&address,sizeof(address)) == 0)
printf("The connection was accepted with the server %s...\n",inet_ntoa(address.sin_addr));
int x=0,d,a[RAW][COL],b[RAW][COL],c[RAW][COL],i=0,j,t=0,k,q,w;




recv(create_socket,buffer,bufsize,0);

for(i=0;i<bufsize;i++)
printf("buffer[%d]=%d\n",i,buffer[i]);

close(create_socket);
}

I think you should send with: "send(create_socket,buffer,bufsize*sizeof(int),0);" and recv with "recv(create_socket,buffer,bufsize*sizeof(int),0);"

Hi ..................
It did not work.I did try ,but it did not work,
there some thing I wondering about.
at the first,two aor three times it works well,and two or three times it does not work,after that may be work ,may be not.I do not know what is going on.

Sniff sniff sniff
Use a sniffer to see what is sent on the wire

Sniffers:
tcpdump (cli)
ethereal (gui)

Hi......
I try to use it but when I compile the code the compile is fails,I do not know why,may be because I do not know how to use sniffers ,you want the true ,it's the first time I listen of them. can you exolain please how to use it,and where can I put the functions you gave me.

sorry,but there is some thing I want to explaine,when I run the programms on boat machines only 361 Bytes of my transmitted data were recieved,the rest of data were zeroes{from 362 to any number}.I do not know why,
abdobl..my regards.
