copied!<p>@adjuster..</p> <p>Acctually, I just got it. When I'm setting <code>SO_BROADCAST</code>, I'm receiving 92 (Package not installed)</p> <p>What package should I install, then?</p> <hr> <p>Edit: The Kernel version is 2.6.18, and you are right! 92 is <code>ENOPROTOOPT</code></p> <pre><code>//Socket creation sock_create(AF_INET, SOCK_DGRAM, IPPROTO_UDP, &sock); //Broadcasting int broadcast = 1; int err; if( (err = sock->ops->setsockopt(sock, SOL_SOCKET, SO_BROADCAST, (char *)&broadcast, sizeof broadcast)) < 0 ) { printk(KERN_ALERT MODULE_NAME ": Could not configure broadcast, error %d\n", err); return -1; } </code></pre> <hr> <p>Edit: I've got this from <code>setsockopt</code> <a href="http://linux.die.net/man/2/setsockopt" rel="nofollow noreferrer">man page</a>...</p> <blockquote> <p><strong><code>ENOPROTOOPT</code></strong><br> The option is unknown at the level indicated.</p> </blockquote> <p>...so, I supose that <code>SOL_SOCKET</code> isn't the right value to pass. I've also tried <code>IPPROTO_UDP</code> instead of <code>SOL_SOCKET</code> with no luck.</p> <hr> <p>Edit: <a href="http://docs.hp.com/en/32650-90372/ch02s10.html" rel="nofollow noreferrer">http://docs.hp.com/en/32650-90372/ch02s10.html</a> says that <code>SO_BROADCAST</code> is an option of the <code>SOL_SOCKET</code> level, but I continue to get -92</p> <hr> <p>Edit: I'm desperate, so I've tried <code>SOL_UDP</code>, still -92.<br> Yes, it is fun :) ... Good synergy! At the end (I hope we get there soon) let's assembly a definitive answer clean and nice! :)</p> <hr> <p>Edit: Even if a hard set the broadcast flag, the <code>sock_sendmsg</code> will fail (-13, "Permission denied")</p> <pre><code>sock->sk->sk_flags |= SO_BROADCAST; </code></pre> <p>I really need some help on this one..</p>
