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). ---------- Forwarded Message ---------- Subject: Re: [uml-user] Static Multicast Routing on UML... Date: Wednesday 01 February 2006 00:09 From: frank evans <[EMAIL PROTECTED]> To: Blaisorblade <[EMAIL PROTECTED]> 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 On 1/27/06, frank evans <[EMAIL PROTECTED]> wrote: > Hi UML'ers, > > OK, NEVERMIND!
