Fwd: Re: [uml-user] Static Multicast Routing on UML...

I'm forwarding the email to the ML since it's intended for that (and I've no 
time to answer right now).

Btw, I think the problem is more likely to lie on port = 0 than on INADDR_ANY 
(you'd at least need to be root to use a port < 1024, and I think port 0 is 
invalid).

HI UML'ers...

OK, I have another issue:  I have a UML (linux-2.4.28 with Debian FS)
running, with eth0 hooked to the uml_switch.  I have a little program I run
on the UML, that wants to open up a UDP socket with an address of INADDR_ANY,
and a Port = 0.  When the program does a connect( Sock, (struct sockaddr
*)&SockAdr, sizeof( SockAdr ) call which returns an error code of ERRO: UDP
socket connect; Errno(22): Invalid argument.  I am wondering if there is
something that does not like INADDR_ANY?

Got any ideas?

Thanks,
Ben Evans
