Is it possible to do dynamically throttled UPDcast transmission? We need
to throttle the data flow to a Logic Innovations IP encapsulator (with
LI's documentation attached with their permission).
The udpcast mutlticast address is considered a single route to the IPE.
The IPE sends out flow-control messages (described in document) that
shows how many bytes are available for traffic for each route every 100
milliseconds in a multicastand comes from a user specified multicast of
its own. Attached is the LI document, again with the manufactures
permission. Also, you can contact Theo Aukerman, taukerman(a)logici.com
for any additional info.
I'm asking these questions because IF this is possible, then this would
be an almost complete framework for an open source Data-casting network,
and can be used for over the air data-broadcasting from any DTV
transmitter or any other system with null packets. I currently work as
an engineer for a TV station that does data transmission, but would like
to move to an open source model.
Hi everyone,
Please confirm my guess (or explain how to implement it).
I need a "sender-timeout", a period of time while sender waits for receivers
to connect, and if none are connected - sender exits without transmission.
The only way to implement this is shell/perl/... script, which starts
udp-sender with --min-receivers option and monitors its stderr. If no
"Starting transfer" is found during specified period of time - it kills
udp-sender process.

Dmitry
http://udpcast.linux.lu/cmd.html states that --nosync is the default
when writing to a file or a pipe, but this does not appear to be the
case; I verified with strace that udp-receiver open()s its output
file with O_SYNC unless you specify --nosync.

Hello,
i would like to run udpcast on a computer which has 2 NICs. udpcast is
using eth0, but i have to integrate eth1
as the used device. (i can do this with the additional command line
parameter -interface eth1)
but the interface eth1 don't come up automatically, i must invoke a
ifconfig eth1 up before udpcast.
But i can only assign a static ipadress to eth1 with ifconfig, the dhcp
option doesn't work.
Has anyone a idea how i can bring up eth1 on this small console with
DHCP?

Markus Forster
Hi,
Can I use udpcast on my pen drive?
If yes, How?

I've only spent a few minutes researching this, but
it seems Apple use a semi-proprietary netboot for
their network boot option (hold down N key). It is
well supported by Apple's NetBoot and NetInstall services
on the Mac OS server. I've seen a couple of howtos
on making Linux with netatalk and patched dhcp do the full
netboot trick.
Has there been anyone able to boot the macbook
client from Linux server for purposes of using udpcast?

Upps, I was talking about the *MAC-Address of a NIC* (MAC = Media Access
Controll, NIC = Network Interface Card), not about the *MAC-PC*!
I know the MAC PC just from stores, never worked with it, sorry.

Hi all,
we have some trouble with establishing a connection over different
VLANs.
The server (sender) is located in one VLAN (10.199.248.0/24) and the
clients (receiver) are located in 10.120.150.0/24.
Between the VLANs work 2 routers (Cisco equipement, Switches are Cisco,
too), but i can't see a connection when i start the sender.
We use an PXE image to boot-up, the server is running under Ubuntu 6.06.
Multicasting between the VLANs is enabled.
I think this is a problem with broadcasting. Does anyone know what we
have to do? I tried already the ttl option, connection
was found but the transfer did not start. I get directly a timeout and
he can't transfer anything.
Thanks in advance for an quick answer!
regards,
Markus Forster
