------- Additional Comments From mike@theoretic.com 2003-03-31 03:33 ------- OK, I'm currently working in this area, any my app attempts to use multicast, so I have a feeling I'm going to hit this problem sooner or later.
A bit of research leads me to conclude that the problem is that Linux prevents you from sending packets to a broadcast address, unless the SO_BROADCAST option is switched on. If you're root, this rule no longer applies, which is why running the program as root fixes it.
This gives us a problem. Windows 9x allows broadcast sockets without any security. Windows NT+ does not (you have to be an administrator).
I'm going to mark this WONTFIX - I believe it's not actually a bug, rather just a part of the Linux security system. I guess we could detect broadcast addresses and set SO_BROADCAST manually in win9x mode, but I'm not convinced it'd actually be a good idea.
Reporter - I'd suggest you just run the app as root and trust it: writing to broadcast addresses is essentially a trusted operation anyway as you can easily flood the local subnet.
