Thread: Program for gateway process that simulates datagram loss

um you have Sink.c listed twice and source.c listed not at all...was this a typo? And what is pastebin - collaborative debugging tool? Finally I would suggest running gateway.c under GDB and when the segfault hits, do a "where" to show the exact line and cause of the segfault. If this does not clear things up Gal I would request that you supply a little more information about the *intent* of the three programs, how they are supposed to interact, etc...


Peace bro...

Oh and while others may not have a problem with this, posting code with line numbers (IOW not ready to compile) slows the help process....

BTW what is this?

Code:

*/running to the localhost/*
 
#include <sys/types.h>
#include <netinet/in.h>
#include <inttypes.h>
#include <netdb.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <strings.h>
#include <unistd.h>
 
int main(int argc, char *argv[])
{
  int socket_fd;
  struct sockaddr_in  dest;
  struct hostent *hostptr;
  struct { char head; u_long body; char tail; } msgbuf;
 
  socket_fd = socket (AF_INET, SOCK_DGRAM, 0);
 <snip>
   unsigned sleep(unsigned seconds); <<== looks like you are declaring a function, not calling one...???
}
 
  return 0;
}

Also your comment tags are backwards at the top of the file negating the first 20 or so lines of the code....

Looking at the source for sink.c....

Is it your intent to send the process ID of the sink program over and over to argv[1]? I only ask b/c that seems to be at odds with what your original question claimed (sending source.c to another socket).....I guess I am confused...
