UDP broadcasting with ANE?

I’m wondering is there any ANE files for UDP that does broadcast on transmitt and receive?

Hi Suman,
the report do:
select * from rsrd_sett_node_a into table t_rsrd
where setting_id = lv_brdcst
and id = 'PR_VARIABLE_STRING'
and objvers = 'A'.
describe table t_rsrd lines lv_indmax.
*get the variable values and its parameters into a variable
loop at t_rsrd into wa_rsrd.
concatenate lv_input_str wa_rsrd-value into lv_input_str.
endloop.
*Split the parameters into an internal table as rows
SPLIT lv_input_str AT '&' INTO TABLE t_result_value IN CHARACTER MODE.
The split use '&' but in this case the values in table are different. In fact run the report with option 'X' don't display the value of variable in input.
How can I do ?
Many thanks.

Unable to receive UDP broadcast packets on PPP connection

I am struggling for two days now with no success. I have two modems (do not ask, some special stuff), that uses dial up (PPP) connection. I tried this on windows XP and it works like a charm. I am sending unicast and broadcast UPD packets. If I
repeat that on Windows 7 i can send only unicast data, broadcast packets seems to be lost somewhere. I tried to use Microsoft Network Monitor and I can see that broadcasted packets are being received on my PPP connection. But after that, they are gone. Somewhere
in the kernel. I truly do not understand why. I disabled firewall, antivirus, base filtering engine, tried to log dropped packed in Windows
Filtering Platform, tried clean WIN7 machine and all that with no success.
Here is a sample packet received on interface, but it has newer reach my app:

Hi,
From your description, you may gather the network monitor traces to ensure which part lost UDP broadcast packets.
Thank you.

Problem with broadcasting with 123-2.JA2

Since I did an upgrade from 122-13.JA4 to 123-2.JA2
we have problems with locally generated udp broadcast in the wl-environment. The clients associate without any problems with leap and has absolutely no problems with unicast traffic. But locally broadcast from one wl-client to the other seems have problems. We use vlans. Downgrade to 122-13.JA4 and all problems are gone. Does anyone share same problems with this release?
any input is very welcome
Oliver

Yes, lots of our clients couldn't even get trhough the dhcp process. downgraded to 12.2(15)XR2 with success.

UDP broadcast over multinetted VLAN

We're having an issue with UDP broadcast over a VLAN that has three IP's configured on it. This is on a Cat 6509.
interface Vlan11
description ZZZZ
ip address 10.10.249.1 255.255.255.0 secondary
ip address 10.10.250.1 255.255.255.0 secondary
ip address 192.168.101.1 255.255.255.0
no ip redirects
ip pim sparse-mode
The device broadcasting is 192.168.101.34.
We've added the global config:
ip forward-protocol udp 4444
And we've tried interface commands like:
ip helper-address 192.168.101.34
and
ip directed broadcast
Nothing seems to help, though. Are there any inherit limitations due to the multinet? Devices on the 192.168.101.0/24 subnet receive the broadcast fine. Devices on the other two subnets do not. Basic routing between all subnets is fine.
Thanks,
Joe

Hi John,
If you're running 2008R2 DHCP, you can fix the DHCP issue that you're having by configuring a DHCP super scope on the DHCP server. We ran into that problem too and managed to get DHCP working on all three subnets. I know it works on 2008R2 but not sure on other versions.
We're mandated to get off the 192.168.101.0 subnet; so, if we can't get it working this way we may need to do a complete cutover including re-IP-ing all devices involved in this dilemma. It's more complicated than I'm stating as this is basically a troubleshooting step to see why it broke. There's an application server involved, an audio streaming server, and some Barix devices. We're attempting to get all the workstations cutover first when we ran into this issue.
Thank you,
Joe

Why WRT54G ver 7 blocks all UDP broadcasts?

My WRT54G seems to be blocking all UDP broadcasts in the intranet side. Is there an option somewhere, which controls this behaviour, because I have not found one.
It does not matter, if I connect my laptop with a cable or by WLAN, no UDP broadcast packets from my server to the laptop go through.
If I connect to either one of my regular switches, UDP broadcast works perfectly.
Note that I'm not using the WAN port at all, so I would expect no filtering on the traffic.

Interesting!
For sake of argument, can you try using the broadcast address of 255.255.255.255 - this is a limited (local network only) broadcast.
Can you see the MAC (layer 2/ethernet) portion with your tool?
The MAC of the destination needs to be all FFs (all ones) for broadcasts.
I am wondering if something is happening at a lower level - like in how switching is implemented in the linksys. I wonder if a linksys switch (only) also does this.
NOTE - ICMP echo (PINGS) do go through my WRV54G to specific addresses and broacdcast the x.x.x.255 addresses.

UDP Broadcast Traffic from Cisco ASA

Hi,
I want to know that, like Cisco IOS Router, Does Cisco ASA pass the UDP Broadcast traffic e.g., TFTP etc...?
Any thoughts ???
BR,
Mubasher Sultan

Hi Mubasher,
Unlike the router the ASA does not forward any kind of broadcast packet (with the exemption of the DHCP broadcasts when DHCP Relay is enabled).
I understand that your DHCP server is providing here the IP address for your TFTP servers. I guess you are using DHCP option 150.
So if the DHCP server is on one interface and the client is on another you can configure DHCP Relay on your ASA.
http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a008075fcfb.shtml
In regards of the TFTP requests these will be normal unicast packets as Cadet said so just make sure that you have the proper ACLs and NAT rules for that.

EEM send UDP broadcast

I need an "action" statement that will send a UDP broadcast to port 1001 with a message of "restart". I have the rest of the EEM script created fine. I cannot seem to figure out how to do this. I have a BGP route that changes every once in a while and when it does the application seems to stop functioning correctly. A restart of the application fixes the issue. The vendor says that if I can send the UDP broadcast then he can program it to see the broadcast and restart iteself. I have created an EEM script that sees the syslog "%BGP-5-ADJCHANGE:" and currently sends an email. BUt we have to manually restart the app. If this is not possible within EEM could it be done with a TCL script and the EEM call the TCL script?
I appreciate any words of wisdom. Thank you in advance.

EEM currently does not support UDP. Yes, a tclsh called from EEM could do this assuming you have a new enough IOS. The UDP extension is documented at
http://www.cisco.com/en/US/docs/ios-xml/ios/ios_tcl/configuration/12-4t/nm-script-tcl.html .

UDP BROADCAST

Hello,
is there any way to send one byte on udp broadcast
(255.255.255.255) port 8999 and listen the response with
actionscript.
Thanks a lot

You would need to either enable multicast-unicast on the WLC or the more preferred method would be to enable multicast-multicast on the WLC under CONTROLLER>General. Unicast is a lot of overhead on the WLC as the WLC has to replicate the packet for every AP that is joined to it. With multicast, you have to multicast routing on the network and PIM enabled on the WLC management interface VLAN, the AP VLAN(s), and the client VLAN(s).
Thanks,

Using UDP broadcast instead of UDP multicast on a LAN (multicast not working on a major UK ISP router)

I've built an Android app using Cirrus that allows users on a LAN to chat in Morse code! - You can find it on the Android Market by searching for 'Morse Intercom'.
It works fine on my network, lots of other networks, but not on probably the most popular fast broadband fibre network in the UK
A friend of mine has let me piggyback on her network from this provider, and the problem appears to be that the UDP multicast packets RTMFP transmits just aren't being put on the wireless network. FYI the multicast address I use is IP 225.226.227.1 port 32112 .
This is probably fixable in the router, but 99.5% of users will never mess around with the router (and why should they), and if possible I would like to fix this in RTMFP.
Is it possible for me to ask RTMFP to not use UDP multicast, but instead to use UDB broadcast for discovering peers on the LAN ? The problematical router (and all others?) supports UDP broadcasting.
I tried setting 'groupspec.ipMulticastMemberUpdatesEnabled = false;' but this just stopped the app working on anything! What is the purpose of this option?
FYI:
To connect without using Cirrus server assistance I use: nc.connect("rtmfp:");
The complete function I use for setting up multicasting is:
private function setupGroup():void
// Create a new Group Specifier object
//trace("setUpGroup: groupSpec = new GroupSpecifier('myGroup/groupA')");
trace("setUpGroup: groupSpec = new GroupSpecifier('" + MY_UNIQUE_GROUP_NAME + "')");
var groupspec:GroupSpecifier = new GroupSpecifier(MY_UNIQUE_GROUP_NAME);
// Enable posting
trace("setUpGroup: groupspec.postingEnabled = true");
groupspec.postingEnabled = true;
// Specifies whether information about group membership can be exchanged on IP multicast sockets
trace("setUpGroup: groupspec.ipMulticastMemberUpdatesEnabled = true");
groupspec.ipMulticastMemberUpdatesEnabled = true;
// Causes the associated NetStream or NetGroup to join the specified IP multicast group and listen to the specified UDP port.
//trace("setUpGroup: groupspec.addIPMulticastAddress('225.225.0.1:30000')");
trace("setUpGroup: groupspec.addIPMulticastAddress('" + MY_MULTICAST_ADDRESS + "')");
groupspec.addIPMulticastAddress(MY_MULTICAST_ADDRESS);
// Constructs a NetGroup on the specified NetConnection object and joins it to the group specified by groupspec.
trace("setUpGroup: group = new NetGroup(nc,groupspec.groupspecWithAuthorizations())");
group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());
// Set the NET_STATUS event listener
trace("setUpGroup: group.addEventListener(NetStatusEvent.NET_STATUS,netStatus)");
group.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
In conclusion - On a LAN with up to 250 or so hosts, I can't see why RTMFP shouldn't be able to use UDP broadcasting as an alternative to UDP Multicasting. Can it, and if so how?
Graham

Here's more information...
When trying to connect with a 3rd party product, the connection request is sent out to my ISP's DNS server with details of the service ID. Of course it won't find anything there.
So then is tries to use NBNS (Netbios Naming Service) on 192.168.1.255, and still can't connect. Then comes back with a TNS error. i tried TNSPING on this address, and it doesn't find it. I have no clue where it gets this address from.
WHY WON'T IT JUST CONNECT TO THE HOST MACHINE AS DEFINED IN THE TNSNAMES FILE???
PLEASE HELP!!!!

UDP messages with a router

Hey all,
I've written a test movie to check the viability of running a
MUS app on a server behind both a standard router and a firewall.
Sadly, my attempts have failed - the TCP messages are being
forwarded just fine, yet the USP messages are being stopped dead in
their tracks at the firewall.
I'm convinced my port forwarding is the reason - sadly,
Director's poor documentation doesn't specifically say the port
range it uses, only the "starting" port being 1627 for UDP. I've
tried port forwarding 1626 (TCP) all the way up to 1647 with no
luck so far.
From searching on this newsgroup I get the feeling that
people have been able to get this working. Can anyone provide some
insight on this?
Thanks in advance.

> I've analyzed my outgoing UDP packets from my client
program and for some
> crazy reason
That's what I meant by "design" in my last post.
During the logon sequence, and if UDP messaging is enabled,
the server sends
a message containing the udp address that the clients will
use.
If you are behind a NAT, and since there is no way to tell
the server your
true ip, then the clients will be sending udp messages to
invalid
addresses - to the server's NAT address that is.
So, there seems to be no solution for enabling udp behind
NAT.
Or at least, not when using the original MUS.
If interested, you can download:
http://xtrema.rtr.gr/beta/Xtrema.Net.857.rar
The package contains:
- a simple serverless LAN chat movie (udp, broadcast)
- a network tools movie (ping, tracert, lookup, wakeup etc.)
- a MUS emulator movie
- the Xtra on which the movies are based.
Notes:
- this is the first, and therefore lightly tested, Xtra build
that
uses overlapped IO and completion ports (the best that NT has
to offer) for
stream communication.
- the mus movie is evolving along with the Xtra, so several
commented blocks
of code may exist in it. Ignore such lines of code..
- if you browse the mus movie scripts, you'll most probably
get answers to
various mus related questions you may have.

Customer Broadcasting - EMail Bursting Broadcast with hierarchy

Hi,
At the moment I broadcast with the broadcast function email bursting to our customer. (single customer)
I maintained a mail adress for each customer.
Now we have a special demand.
I should broadcast to customer groups.
Customer Group is a special hierarchy level in our customer structure.
For example one customer group have 10 single customer.
So for example the customer from hierarchy level 2 should get a report with all customers in hierarchy level 3
Is it possible to work with hierarchies in the email bursting function ?
Thanks
thomas

Hi Thomas,
Im not sure by hierachy group but you could so it by role. So all customers who you assign a certain role will get a certain report.
Nick.

Error with ANEs in ASC2

I'm trying out SDK 3.6 with ASC2 on OS X, and am having an issue with ANEs. Running my project in adl on OS X, everything is fine until I include an ANE in the project. This causes an immediate "VerifyError: Error #1079: Native methods are not allowed in loaded code." to be thrown. I've tried recompiling the ANE with the latest sdk, but no deal, same problem. Anyone gotten an ANE to work with the new SDK yet?

Is it possible that the way ASC 2 is configured to link to the ANE is not marked as external? Said differently, is the ANE accidentally on the -library-path and really should be on the -external-library-path?

Possibility of combining exception broadcasting with master data bursting

Hi Experts,
We have a scenario where it is required to combine exception broadcasting with master data bursting.
As per my understanding if you choose broadcast method as 'exception broadcasting', there is no option for choosing 'master data bursting'.
Am I missing something or Is there a workaround or some method to achieve the same.
Thanks
Rajeev

Hi,

How can I disable SSID broadcast with Time Capsule?

I have always disabled the SSID broadcast with other devices. It is a big help with securing the networks. Can this be done with Time Capsule? If yes, please tell me how.
Thanks.

I have always disabled the SSID broadcast with other devices. It is a big help with securing the networks. Can this be done with Time Capsule? If yes, please tell me how.
You can by turning on hidden network.
Open the airport utility .. click on your TC, and then edit.. go to the wireless TAB. Click on wireless options. Click Create hidden network.
Let me add in modern world.. it is totally useless. A person can see your hidden network using any standard wireless analysis software. It adds no security at all.. and WPA2 Personal with a decent password 10-20 characters mix of upper and lower case plus numbers is still solid.. add more characters if you are paranoid.. but honestly hiding SSID does nothing.
http://www.howtogeek.com/howto/28653/debunking-myths-is-hiding-your-wireless-ssi d-really-more-secure/
If you did not know it is not part of the IEEE wireless standard.. it therefore often leads to problems with clients.
There are many other reasons given in the article above..

Using Broadcaster with Internap CDN for live streaming

Has anybody successfully used Broadcaster with Internap's CDN for live streaming?
If so how are you configuring broadcaster?

What are your current settings in FMLE ?
What is your input feed? from webcam? external HD camera? Encoder card?
If your connectivity approved you can raise up the bitrate and set higher output size.
