  Hello everyone,
  

  
  I have a very annoying problem. Bear in mind  that I'm relatively new in the field...
  

  
  I try to modify the ping program in order to send audio data from a raw binary file. The file has no header at all, just data. I'm programming in C, in a UNIX/Linux environment.
  

  
  Each packet I send has a chunk of the file, on receiving back the packets (remember that I'm taliking about ping) the corresponding function saves them in a output file.
  

  
  Anyway, the problem is that although the sending packet contains the audio almost fine, in the receiving packet  the audio is scrumbled and I can hear only some sections of the audio I was supposed to send. I have tried many things, including changing buffer limits, but nothing. In addition, I am preety sure that the receiver is sending the packets back in the order it received them...
  

  
  If anyone has a clue, please help. thanlk you all.

  the provect uses icmp for a chat program.
  find out how it works, then adapt for binary data rather than ascii .
