This was working and now it has stopped.
Have a UDPcast server running on a HP DL360G5 with 4 NICS. One
connected to an internal infrastructure (eth2) and another connected
to a dedicated switch with the client systems on the same switch (eth3).
When i run the UDPcast send or receive, using the following command:
udp-sender -f /home/base.udpc --interface eth3 --point-to-point --full-
duplex --max-bitrate 600m --nokbd --portbase=9922 --min-receivers 1 --
rexmit-hello-interval 5000 --max-wait 300
I get the following error message:
Udp-sender 2007-03-23
No suitable network interface found
The following interfaces are available:
lo 127.0.0.1
eth2 10.46.0.251
eth2:1 10.46.0.1
Interestingly, an ifconfig show eth3 as a valid network adapter, but
the udp-sender does not see the device. This was working last week,
and nothing has changed on the server
I have tried everything, restarting DHCP, removing the interface and
adding again. Rebooted the server, restarted the network stack
manually. nothing seems to help.
Using SUSE linux 10 as the base server OS.
Using the latest udpcast (udpwindows port, I cannot obtain more than
15.2mbit/s when using a net express bonded nic as the receiver. This
virtual nic has no problems obtaining 90mbit/s with smb or ftp (the
'bonding' is mac based outbound only and works as passthrough for individual
clients), so it's not expressly (pardon the pun) an issue with that.
Testing with other machines with normal nics (on the same switch with no
changes in topology) I'm getting 45+
The physical nics are d-link dfe530tx rev c cards.
There's no error messages (no resends at all).
Any ideas? (other than ditching the nic express of course :p )
I send lsmod lspci e dmesg of my hardware under ubuntu 8.10
My disk is recgnized as sda1 but udpcast doen't do it!

Does it work on an Ubuntu install disk, or on a Knoppix? If yes, could you
include the output of lsmod? Mostly, the modules whose name contains ata or
scsi are of interest
Thanks

Dear UDPcast Members:
0) I am new to this mailing list. I was recently made aware of the
UDPcast facility. I am impressed by its simplicity and cross- platform
interoperability.
1) What brought me to you is the search for a networking tool that I
have identified for many years. It appears that if we can configure the
front end of the UDPcast (just the initial phase of "broadcasting" and
"listening" part) to provide a near-real time overview of all active
devices on a network, we can empower mass consumers with a pieced of
crucial baseline information., that is, the instant health status of
their SOHO (Small Office Home Office) or Residential network, even
without an IT manager nor any technical know-how.
2) I am a system engineer trained in hardware designs emphasizing
traditional RF and telephony. I can identify potential new applications
based on capable technical ingredients within an existing product.
However, I am not good at the actual detail implementations, especially
software. Since UDPcast is the result of an open source effort, I
thought that it would be prudent for me to check with you to see if
anyone would like to work with me on the idea that I have, so that the
outcome can benefit the general public.
3) For those interested in what our team has accomplished up to now,
please have a look at a set of overview slides:
http://www.avinta.com/phoenix-1/home/ProjectPhoenixPrimer.pdf
With basic network architecture and transmission capabilities
identified for satisfying MaP (Mom and Pop) type of users, we have been
looking for the next level intuitive building block. That is, with so
many devices possible on a SOHO network, how could an owner get a
concise visual summary of which ones are currently online? Once this is
provided, MaP will have a clear reference line to deal with potential
cause of network issues, either by doing their own "unplug and swap"
substitutions or having enough confidence to deal with techsupport
personnels.
4) I will be glad to write then submit a product specification type of
document describing details of my thoughts as an outline to begin more
specific discussions, if anyone would indicate the interest in working
with us. As implied, the end product of this effort will be a utility
distributed to mass consumers for them to enjoy network services because
they will be able to "manage" the very basics of their own network.
I look forward to any thoughts and comments.

Hello folks,
I would like to use Udpcast to send files through the wireless network I
have here, but software doesn't identify the wireless pci card of computers,
only the ethernet card. Looking in the "other" drive options, I didn't find
the correct driver for wireless pci card.
What can I do to use udpcast with wireless network using RaLink RT2561/RT61
rev B 802.11g ??
Thank you !!
Marcelo Martini.
Hi,
I am having a problem to compile udpcast 20081130 using gcc 3.2.2. I got
the error messages like:
...
udp-sender.c: At top level:
udp-sender.c:425: parse error before '}' token
udp-sender.c:453: parse error before string constant
...
The details are attached.
Does udpcast only support gcc 4 now ?
Thanks.
Steven.

Hello all,
I've never used UDPCast but I've been ask to come up with a solution to
image 20 computers at once in a training room.
I figured I could have one computer set as a server and all others set
to boot off the server, this way they would boot and receive only when
the server computer was powered on.
My problem is that each computer will have to have a unique name. If I
broadcast the same image over the network how can I change the computer
names without sitting at each individual computer, I'm trying to make
this completely automated.
