we have different kinds of monitoring software, each one has its own pourpose and none of the can do all the monitoring by itself.
I was trying to centralize all four platforms on a single web site, so it will be easy to check all monitors faster and easier.
2 of the monitoring services have a linux X console, and can be exported as through ssh -X.
The other two have web interface, so it should be easy to embedd.
Does anyone know how I can embedd this Xwindows on a web iframe? As an example I could say that I want to embedd xclock on a web frame. Is it possible?
thanks.
You can capture portion of X11 display and stream it with ffmpeg using x11grab command and video streaming server.
See:
x11grab
ffserver

I am planning to implement the functionality given by SSH -X . This is used to open GUI based application remotely. So I want to understand what are the components involved and should be implemented.
I know how to setup this like starting VNC server in the host and assign DISPLAY variable.
And do SSH -X connection from remote client and execute the required GUI app shell script (for example xeyes, xclock etc.,).Please share if anyone is having more advanced information. My requirement is to design a web based "SSH X" client. There are lot of tools available in the market for Web SSH but no tools with SSH X11 forwarding support.
The X11 protocol is intrinsically network transparent, so ssh -X simply sets up a port on the remote system and sets the DISPLAY variable so that X programs write the X11 protocol to that port, which it then streams back to the local side. (This is a simplification; there's also authentication involved.)
If you want to do this in the browser, you'll first have to have some sort of server-side component that does the SSH operations and converts the stream of data to something the browser can use. Browsers do not allow opening arbitrary TCP ports to remote systems in JavaScript, since doing so is a massive security risk.
You'll also have to find some way to render the X11 protocol in the browser. Essentially you'll be implementing a web-based X server (hopefully in something like WebAssembly). You should read the existing specifications for that and look at popular open-source X11 implementations, such as Xorg.
I should point out that this is a colossal amount of work due to the requirement to implement a full X server. VNC-based protocols are much simpler because they don't need to implement drawing primitives, only render (possibly compressed) images streams on the screen.
I currently have a video chat app working on web(Flash) and android via Adobe AIR, it uses Adobe Media Server (RTMP) as backend for video streaming and shared objects, my question is, if there is another server or solution that provides many to many live video broadcast maybe using H.264 codec from android and iOS, have some sort of user list and room list stored in a database or similar, I want to move away from Adobe as it has many limitations on mobile devices.
Live video is crucial in 1 to many broadcasts that will have hundreds of viewers at the same time.
Thanks for reading!
Ulex.fr created an RTMP connector for Asterisk (the free PBX platform).
Used with the Asterisk Vonference application, it allows you to create conference rooms for 1 to many configuration, with audio and video. The only one limitation is the power of your server. You can plan a scalable architecure in order to broadcast one video to many (many could be unlimited). We developp a specific protocol to connect and manage the connection based on the telephony events. I think we already done a direct RTMP connection that skip this protocol too.
All the project done by ulex.fr is free, OpenSource and GPL.
Get the full project here : https://github.com/voximal/asterisk-rtmp
(a live demo is available)
We already develop an RTMP stack for android with video (using the camera), this allows you to create your own application without using AIR.
You can check Adobe Cirrus, it's still in the beta stage (actually IMHO Adobe forgot about it), but it works on web, desktop and mobile too. Check this Video Phone example, it can handle chat applications without a problem.

You could take a look at Red5 Media Server, which is an open source solution. There are other options like the Wowza's solutions on AWS, but they come a higher cost...
Ok as today, we have decided that we can manage the users,rooms and messages via Google Firebase Real Time Database, and the live video stream using ANT Media Server
I'm looking for a platform with Web UI access that allows me to do the following:
Maintain a list of computers and add / remove based on their IP address.
Provide the SSH information for each computer machine.
Monitor if the machines are up ( ping ? )
Restart the machines with a web UI using the ssh information on the backend of the application.
I'm close to start making such an app myself since I can't seem to find anything close to that in the internet. Any clues if such an application exists ?
You might want to take a look at MeshCentral: https://meshcentral.com/ - you can add systems that you are managing and do some remote operations.
http://info.meshcentral.com/: Meshcentral is open source and is both a peer-to-peer technology with a wide array of uses and web service that is targeted for remote monitoring and management of computers and devices. Users can manage all their devices from a single web site, no matter the location of the computers or if they are behind routers or proxies.
If you are looking for source code you could take a look at the "Open Manageabilty Developer's Toolkit" http://opentools.homeip.net/open-manageability. This tool was built for managing systems with Intel Active Management Technology, but it does a lot of what you are looking for. You can download the source and see if you can use any of it if you decide to write your own UI.
I am curious about relaying messages from one app on one machine to another machine. I have a shared network storage readily available to me. My thought is that I want to run an app on a single machine that runs intranet uploads. I cannot control anything about the domain or the shared network storage other than creating files/folders.
I want this app on its own machine to be able to report somehow to a completely different application installed on completely different user machines (so in case of errors lets say, users could intervene) and at some point, across platforms (vb.net/Access/etc).
The first thing that hit me was to stream write the upload app's status to a text file, and then have a timer on my users end app that monitors the file that the upload app writes to.
However, before implementing, I am wondering if I am reinventing the wheel, and theres a better way to do this. I am seeking simple solutions, and eventually I would like to integrate this into VBA/Access. What does SO think fits the bill? What is the downside to streaming a "log"?
You're reinventing the wheel. This is Message Queuing. There are many existing solutions to do this, including MSMQ (built into Windows) and RabbitMQ. There are also cloud based services like Azure AppFabric and Amazon Simple Queue Service.
Does anyone know of an open source web service/wcf service that can stream media content to clients? In particular I am looking for something that could access my music collection and stream it to a client (could be a client browser, win mobile app or even iphone application).
I guess it would have to be WCF based as I'm not sure that webservices do streaming really well. Also Windows Media Streaming Services is not the best way to go as the service should operate from a vista/xp machine (preferably).
If not, does anyone know the best way to start going about creating something like this - I'm not sure I know where to start with this one, although I can see many many uses for such a service!
Even though it's not open source, Windows Server 2008 has a Streaming Media role that will do what you ask. Of course, you'll need to have a server to put it on.
I tried Orb and it is quite good, apart from the fact that it hijacked my tuner card so media center would no longer work. However I'm going to try and create a home grown version.
Orb (www.orb.com) will stream your media to just about anything with a web browser. I've been running it on an XP virtual machine for about a year. I love being able to stream my entire media collection to my phone while I'm working at a client's site.
While it isn't open source, it is free and relatively well supported. One of the best features is that the architecture is set up so that there are no special requirements for your firewall -- it just works.
