I want to send a message to everyone(broadcast) in my subnet(LAN) so as to prevent them using Internet due to repair work that's going to happen. How do i do that ? I can't use "wall" because no one is logged on some server.
I want to send a packet that opens a new Tab in web browser and displays message that stop using Internet during a certain duration.

You might be interested in something like this. I am not sure if this will work in your LAN environment, but typically it should mess up with the entire LAN :D
you can use sockets to send a message to everyone connected in LAN, you can use java and when you want send a message to all clients, every client will see a msgbox with the information you want display....
net send command will be helpful in windows machines. Im not sure about linux.
Plz refer the following link for more Info.

This is a solution shared by my senior( Hope it helps anyone who views this post). What we can do is to do DNS spoofing and redirect everyone's request to a server where you can show the required message.

As what title said, i still confusing and turn around in deep-hole and get lost about one month in it. So i really need help.
I would like to create client-server online game, and separate Client and Server to different project with each other, and for understanding, i don't using any NetworkManager and script from demo project.
Why i do that ? I want client is always remote client, and server always dedicated server that mean no local client.
All communication until now i using custom message from MessageBase and it ok for me. But the problem come with spawn game object, sync with all remote client, i don't know how to do that.
The server just handle connection, message and send back to client so it just GUI only, then i want to ask that it MUST be share scenes at client ? Does it NEED TO DO IT ?
The client is a remote client, so how to sync movement, spawn, and etc to another client via server ? If i using transfer message base on MessageBase, it look so complicate than using SyncVar or Command. But i don't know how Server handle Command, because it separate different with Client. Can anyone help ?
AM I WRONG WAY ?
I have an app controlling my AVR on a local network and I'm trying to embed some of the functionality into another app written by myself. I've started up WireShark and started controlling the volume, which shows up as:
GET /ctrl-int/1/setproperty?dmcp.device-volume=-15.750000 HTTP/1.1
I'm not totally up on this type of http control but i'd like to know if this is enough data to be able to send the same request via a browser or terminal etc.
cheers
Without knowing the avr you can't realy tell. But you should be able to send the command via
avr-ip/ctrl-int/1/setproperty?dmcp.device-volume=-15.750000
in the browser or from you app. The ip should be in the wireshark logs as well.
If that works it was enough information.
I'm working with freeswitch and I made the connection between my server and another one, for hearing each other I used the codec G729. The issue is the next: I call them, the call is established and I can hear the other part perfectly but they can't hear me and they can see the audio packets coming to their server but they can't hear me, any idea? Thanks!
I'd start by looking at the firewall on the remote machine. libpcap will allow you to see all packets hitting the box before the firewall rules are applied, so it can be a little deceptive. So there's a good chance that the firewall is blocking the packets.
Also, you didn't specify what the other user is connecting to their server with, and how. So if they're connecting to their server from behind NAT, then you could just be experiencing the typical one-way audio issues so common with NAT scenarios. Check out http://wiki.freeswitch.org/wiki/Nat for more info.
This issue doesn't seem to be directly related to the g.729 codec or you'd have most likely gotten a 488 SIP response.
It's possible that the person on the other end isn't able to decode the the G729 stream.
What kind of phone are they using?
I would google that phone model and try a known supported codec for it.
Then I would setup your Freeswitch to encode for that codec.
If that works then it's likely an issue with the phone.
Hope this helps.
Getting this error message in the browser:
Attention!!!
The transfer attempted appeared to contain a data leak!
URL=http://test-login.becreview.com/domain/User_Edit.aspx?UserID=b5d77644-b10e-44e0-a007-3b9a5e0f4fff
I've seen this before but I'm not sure what causes it. It doesn't look like a browser error or an asp.net error. Could it be some sort of proxy error? What causes it?
That domain is internal so you won't be able to go to it. Also the page has almost no styling. An h1 for "Attention!!!" and the other two lines are wrapped in p tags if that helps any.
For anyone else investigating this message, it appears to be a Fortinet firewall's default network data-leak prevention message.
It doesn't look like an ASP.NET error that I've ever seen.
If you think it might be a proxy message you should reconfigure your browser so it does not use a proxy server, or try to access the same URL from a machine that has direct access to the web server (and doesn't use the same proxy).
This is generated from an inline IPS sensor (usually an appliance or a VM) that is also configured to scan traffic for sensitive data (CC info, SSNs etc). Generally speaking, the end user cannot detect or bypass this proxy as it is deployed to be transparent. It is likely also inspecting all SSL traffic. In simple terms, it is performing a MITM attack because your organizational policy has specified that all traffic to and from your network be inspected.
Hallo, developing a bb app I need to make http connections to get files, images etc.
In simulator all works, but not in device.
I bought a BlackBerry but I want to test my app without a sim then without a bes.
How do I need to set my device? and how do I have to compose my url?
I just have a bb device with wifi available
Thanks all :)
Sergio
As answered for this duplicate question...
This was a tough one for me!
As Mark said you have to put some parameters in the url to make it work on the device. You shouldn't do it by hand but use the ConnectionFactory instead.
As you may thing this would just make it work but it doesn't!
The real problem is that not the url has been altered because it has ;interface=wifi;deviceside=true in it (in my case). Depending on the webserver accepting your request this could broke the code.
A solution I tried and that works is try to happend a fake parameter like
&foo=true -> &foo=true;deviceside=true
This will result as a standard parameter for the webserver but your device would use it to driver your connection.
On the simulator this work without this extra code because behind it there is a BIS server for you. On the device (as in my case) there isn't because I'm using a development device unregistered and without SIM (just wifi).
Another point is that the HttpConnection class doesn't handle HTTP 302 Redirect and if you get one you have to handle it manually.
Try appending ";interface=wifi" onto the URL when using a device (instead of ";deviceside=true"). This will force a Wi-Fi connection (assuming the device has Wi-Fi).
