Broadcast UDP

Hello everybody,

I'm new to Inferno OS, but I already like it really much and have lots of ideas of how to use it in some real projects.

I'm going to implement some dynamic service-announcement and discovery. And I'm going to do so via broadcast udp datagrams.

I've thought that it could be as simple as 'listen "udp!192.168.1.255!1234" {somecommand}' but that doesn't seem to work. Please tell me, are there any simple ways (in sh or limbo) to send and listen for broadcast udp packets? I've also heard of more low-level way of doing that, providing inferno with raw udp headers. But that's too difficult to understand, and I haven't found any docs or examples.

Or maybe there are some existing service announcement/discovery options?

Thank you in advance!

Null characters, mangled names, ... it looks as though the file is corrupt, or at least cc's view of it.

Re: Broadcast UDP

There's an example in /appl/lib/virgil.b, although it's mainly useful for the UDP/IP interface code.

The surrounding code is very old, and could be treated as an exercise for the reader in using channels and processes better.

In particular, that technique involving the global "done" variable isn't the way good Limbo would shut down the timer.

See ip(3) for details of the UDP software header scheme, and ip(2) for IPaddr and operations on it.

The ip(2) module also has functions (used by virgil.b and a few others if you grep for them) to work

with Udphdr, which should help. Unfortunately (I've just noticed) the Udphdr type apparently isn't documented,

but the examples in the tree should help.

Re: Broadcast UDP

registries(2) and registry(4) provide a 9P-based service registry.

Re: Re: inferno on netbsd 5.1.2 problem

I downloaded the code from mercurial repository, I will download again or try the zip file.

emu/port/devip.c --> Address family not supported by protocol

Hello,

I had to revert recent changes in emu/port/devip.c before being able to compile Linux/386/bin/emu

Anyway, it looks like that's not enough :

; cat /include/version.h

#define VERSION "Fourth Edition (20120820)"

; cat /net/tcp/clone

cat: cannot open /net/tcp/clone: Address family not supported by protocol

; os uname -a

Linux VM1404 2.6.18-308.8.2.el5 #1 SMP Tue Aug 21 11:54:17 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

Any idea how to fix that or where to get a working binary ?

BR

Maybe this is because Inferno in Linux uses IPv6 by default, which can be
disabled in your kernel? Try to replace "ipif6" with "ipif" in
emu/Linux/emu and emu/Linux/emu-g and rebuild Inferno.
