and what's about to do a kind of

client some server of yours at some place ====== ====================== send(petition to you server) . \____ Annotate that date for later use. timeout(wait(response)) All is okay (they has | pay you, and so): |____________send(ACK to client)

i don't know how to call it, ^_^>, but it could be your solution:
  1. You install a script that sends a request every week or day or hour or even every 60 or 30 seconds (whatever you want).
  2. If you have a server (you must have a server for this scheme to work), then logs the client request (something like this: [Sat, 11 Feb 2006 10:29:55 +0100] ID:SOME_ID_YOU_ASSIGN_TO_THE_CLIENT received from the ip:x.x.x.x an acknowledge request
  3. Your server sends a reply to your client.
  4. If the client didn't receive the ack whitin X secs, then, it sums one to some counter ($counter++).
  5. If the client, didn't receive any ack in X succeed times ($counter > X); then do something for preventing the client to use the program (this could be a thing a little bit nasty ... like to auto-rm, to introduce some extrange byte, to make the perl compiler to abort, or to make the binary not to execute ...)
  6. Everytime the client have a response ($counter=0); not worries and continuing serving

So, when your are not agree with the client, you disconnect your application or filter the client ID you assigned. If the client, filters your ip, the application will autoremove (or so). If the clients, changes its IP, you can know it, and the application will work. If the ...

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 or How to display code and escape characters are good places to start.
