Salut !
Je peux juste te dire comment le faire en langage système Windows, si ça peut aider :D

ping -a xxx.xxx.xxx.xxx > logping.txt

bj,

en réalité je crée class server et client comme ça: puisque /t pour écrire dans.txt mais je sait pas quelle st le pbm en plus j'ai autre class mais le résultat de ping est envoyer sur le console

Server serv = new Server();
serv.lanchServer();

}

try {
ServerSocket servsock = new ServerSocket(8888);
if (this.executeCmd("cmd /c ping 127.0.0.1 /t c:\\asma.txt") == true) {

File myFile = new File("c:\\asma.txt");
while (true) {
Socket sock = servsock.accept();
byte[] mybytearray = new byte[(int) myFile.length()];
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(myFile));
bis.read(mybytearray, 0, mybytearray.length);
OutputStream os = sock.getOutputStream();
os.write(mybytearray, 0, mybytearray.length);

os.flush();
sock.close();
}
}
}catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}

private boolean executeCmd(String cmd) {
try {
Process proc = Runtime.getRuntime().exec(cmd);
try {
if (proc.waitFor() != 0) {
System.err.println("exit value = " + proc.exitValue());
}
} catch (InterruptedException e) {
System.err.println(e);
e.printStackTrace();
}
} catch (Exception e) {

return false;
}
