HI Krishna, It is not printing the length,stucking in that statement it self. I am sending about 10 characters from the client client using the following code to send: char buf[10]="123456789";
iov.iov_base=(void *)buf; iov.iov_len=(size_t)10;
msg.msg_name=NULL; msg.msg_namelen=0; //sizeof(server); msg.msg_iov=&iov; msg.msg_iovlen=1; msg.msg_control=NULL; msg.msg_controllen=0; msg.msg_flags = 0;
for (i=0;i<NUM_PACKAGE;i++) { //strcpy(buf,"1");
oldfs = get_fs(); set_fs(KERNEL_DS); error = sock_sendmsg(Socket[0], &msg,10);
/* len = sock_recvmsg(Socket[0], &msg, (size_t)buf, 0); set_fs(oldfs);
if (len<0) printk(KERN_ALERT "ERRO receive ########\n");*/
if (error<0) printk(KERN_ALERT "Erro send msg ERRO = %d buf=%s\n",error,buf); }
Server side using the following code:
iov.iov_base = (void *)buf; iov.iov_len = (size_t)10;
msg.msg_name = NULL; msg.msg_namelen = 0; msg.msg_iov = &iov; msg.msg_iovlen = 1; msg.msg_control = NULL; msg.msg_controllen = 0; msg.msg_flags = 0;
len = 0; for (i=0;i<1;i++) { oldfs = get_fs(); set_fs(KERNEL_DS); printk(KERN_ALERT " before recieving message \n"); len = sock_recvmsg(newsock, &msg,10, 0); printk( KERN_ALERT " Recieved message length is %d \n",len); printk( KERN_ALERT "recieved message is %s",buf);
}
Am i doing wrong?? Please clarify... Thanks Bhaskar -----Original Message----- From: Krishnakumar.

Hello Bhaskar,
What is the return value you are getting. ie. Did you try printing the return value and see what is being printed.
Some thing like the following.
> len = sock_recvmsg(newsock, &msg, (size_t)buf, 0)
printk("Return value = %d \n", len);
> printk( KERN_ALERT "recieved message is %s",buf)
Hope that helps, Regards, KK.
