[ECOS] TCP/IP stack: robustness agains port scan

[Andrew Lunn]

> Can't read initialization parameters: Connection reset by peer

tcp_echo.c:

    // Wait for "source" to tell us the testing paramters
    if (do_read(e_source, &nparams, sizeof(nparams)) != sizeof(nparams)) {
        pexit("Can't read initialization parameters");
    }
  
 void

...

pexit(char *s)
{
    TNR_OFF();
    perror(s);
    cyg_test_exit();
}


Since you have not told the test program what to do, its exited!
Hence it will not ping anymore.

Reading the code solves most problems very quickly.
