Moin!
I don't know if this is the right place to ask, so I'll ask:
I try to send udp to my networks broadcast-address. All I get is a
"permission denied", so I tried to use setsockopt, but that doesn't work
either. It gives my a "protocol not available".
What do I have to do to send my package?
--snip--
ret = setsockopt(my_socket, IPPROTO_UDP, SO_BROADCAST, (void *)&flag,
sizeof(flag) );
ret = sendto(
my_socket,
wake_msg,
strlen(wake_msg),
0,
(struct sockaddr *)&dst_address,
sizeof(struct sockaddr)
);
--snip--

Try setsockopt(tx_socket,SOL_SOCKET,SO_BROADCAST,..).
And use an actual broadcast-address as sender.

Use ReiserFS to get a faster fsck and Ext2 to fsck slowly and gently.
