Thanks for the fast reply.

Yes, the server requires to receive the heartbeats in every 10 seconds.

Let me write an example. It's based on a wireshark capture.

  1. The server listens on 4 ports 8020, 8019, 8008, 8003. These ports are reserved (this is a switch online all the time, it doesn't really matter I think).
  2. The client sends the first heartbeat from ports: 53036, 53037, 53038, 53039 to ports 8020, 8019, 8008, 8003. This repeats in every 10 seconds.
  3. When server receives them replies from ports 8020, 8019, 8008, 8003 to ports 53036, 53037, 53038, 53039.
  4. If there are test results ready on the server it sends them to ports 53036, 53037, 53038, 53039.

If possible I would like / have to write a single client.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
