Glad to help!

I'm still confused why this work this way, since 4210 is not the local port, but the broadcast port.

It's the port you're listening on, on the local machine. (The sender is not necessarily sending from their port 4210, they may be sending from a random port, but their packets are addressed to port 4210 on the receiving side. Update: You can see this in the tcpdump output you showed: "192.168.0.50.49153 > 192.168.0.255.4210")

BTW, if you want to get the address from which the packet was sent, you can call $sock->peerhost immediately after the recv.

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 or How to display code and escape characters are good places to start.
