Please please help in setting up Turn server in Ubuntu, such that we can have video call even connecting from different network.
I have installed using below command in Ubuntu 20.10 :
sudo apt-get install Coturn.
Can any one suggest how I should configure turn server to achieve above mentioned issue.
You should start looking at the example configuration.
Adapt it your your needs (host public IP address and realm), then restart coturn.
Then you can test it with tools like test.webrtc and WebRTC sample for Trickle ICE (or your own client application).

I would like to ask for help, i have installed the Resctomm SS7Stack. I can open the GUI but i can't add a Sctp server ,Sccp rule even i can't sign out.I tried using a sheel command and it's working. My OS is Ubuntu 16.04.
Thanks in advance.
I am new to Hadoop and the Big Data world...
I have installed the Hortonworks Sandbox VM in Virtual Box. It's working great...
Can someone tell me how to install Firefox within the VM? I need it to use NIFI
Thanks a lot for any help!
Installing a browser on the VM and using it through VNC will typically be very slow. The best option is to set up an SSH Tunnel and do a local forward. If you use the PuTTy ssh client on windows then you can follow the following instructions on setting up the local forward which will allow you to use your browser on the host operating system to connect to the NIFI instance running in your VM.
I am using vSphere client to get informations from the installed VM.
I have gone through the following link :
http://benohead.com/getting-info-from-your-esx-server-using-the-vmware-infrastructure-vsphere-java-api-part-1/
and managed to get which ip's are up/down. I need the IP address.There is no tools installed. Is it possible to get IP address without installing Esxi tool?
You need to install the VMware tools if you would like to fetch the IP address. But without installing the VMware Tools there is an another way to fetch the IP address by using VM Name
In VirtualMachineConfigInfo class, getName() will return the VM Name or by using vm.config.name will return VM name and then pass the VM name to the below code
String ipAddress = InetAddress.getByName(<<VIRTUALMACHINENAME>>).getHostAddress();
Note: This code will works only if the host name is resolvable.
In short, it isn't. If it was, that'd break the whole illusion of virtualization.
There is another way, though, but it requires instrumenting the VMs. If you can install an agent inside the VM that broadcasts/pings it's IP to the outside world through some mechanism, that'd be a solution. Can't think of any other way you can get the IP of a machine. Not through the vsphere sdk definitely.
As part of a TDD (test driven development) project I want a simple OSX service/server that simply forwards data between two clients. The purpose is to enable communication between one piece of code running in iOS (being tested) and another running in OS X.
I think I need both parties to connect to the server for the duration of the test, which points at TCP
There are lots of examples for creating simple clients using NSStream, but have failed to find what creates the Server side.
I would have thought it would be normal for this forwarding software to be a client of the final server, rather than both the other pieces of code being a client to it (as it's both counter-intuitive and somewhat difficult to acheive):
iOS App -> Forwarding Server -> OSX Server
You can achieve this using netcat (which is installed by default on OSX), simply with:
$ nc -l -p local-port -c "nc osx-host osx-port"
(see below)
and the iOS app simply needs to connect to local-port on whatever machine this forwarding server is running on.
EDIT When I actually tested my answer I found that the netcat supplied with OSX cannot support port forwarding, and the answer I supplied only works with the Linux version (I believe there is a BSD-rewrite which OSX uses).
Anyway, this can be achieved if you are happy to install macports and use socat. Here's a working example that redirects port 8888 to www.google.com:80:
$ sudo port install socat
$ socat TCP-LISTEN:8888,fork TCP:www.google.com:80
If you then connect to http://localhost:8888 within your browser, this will hit Google.
Port Forwarding In Windows for iOS .
1. Install Python 2.7 on windows system
2. Connect your iPhone to windows system
3. Download USB MXD1.0 and put it in C Drive
4. Run Command Prompt : OpenC:\usbmuxd-1.0.8\python-client in cmd
5. Run **\Python27\python.exe tcprelay.py -t local port:remote Port**
Eg :**\Python27\python.exe tcprelay.py -t 9892:9892**
We wrote a small prototype web app using Pharo and Seaside and we want to now demonstrate to the suits that the app can be deployed into our standard Linux build. We use a mix of CentOS, Ubuntu Server and Gentoo which are run headless since most of our apps are JAVA/Apache based. Only port 80 and 443 are open to the outside world.
What are your experiences when hosting Seaside/Smalltalk server side apps?
it runs great, btw you can get free hosting for your seaside app at:
http://www.seasidehosting.st/
for more power you'd need your own server of course...
some benchmarks here:

The Seaside Book has a chapter on deployment. It describes how I typically deploy a Seaside application.
I just use a ssh tunnel to get the X display on my local machine. I'm using slicehost (US) from the Netherlands, so I have a ping time of 135 ms. That's not that nice, but ok.
Next step will be Lukas Renggli's remote frame buffer package to use a vnc viewer.
Let's see what Miguel Cobá had to say about it on it on the Gemstone mailing list:
If you have already installed a RFB in your machine then use it.
If you have RFB installed in your image and it is accesible from your
client machine, use it
But, both of them are unencrypted. If you want to encrypted you must
setup a tunnel (maybe with ssh or maybe TLS).
I think that that is redundant because you must use a tunnel and then
the RFB. So what I do, in linux is to install the minimal X libraries
and then forward the X session to my local machine.
In the server (Debian/Ubuntu instructions):
aptitude update
aptitude install xbase-clients
aptitude install xtightvncviewer
Test it from the client machine:
ssh -X remote_server
squeakvm gemtools.image &
This will start the squeakvm process on the server, but all the graphics
will be shown on the local machine (the Xserver for this particular
scenario).
Also, if you install RFB on some of your images and start them headless,
you can use xtightvncviewer to connect to inside the image through the
RFB server.
ssh -X remote_server
xtightvncviewer localhost:0 &
this will run the xtightvncviewer on the remote server but, again, will
show on your local machine. Supposing you have your image in the remote
server running RFB in the first display.
Which is the advantage:
- You don't have to open ports for RFB on the remote server
- You transmit everything encrypted through ssh
- You only run the commands on demand in the remote server. You don't
have to have VNC running always.
- You can configure your RFB in the image to accept only localhost
connections and not from everywhere.
Martin McClure adviced me to take a look at NoMachines NX (less chatty X),
but that's still on my todo list.
For another set of deployment instructions, take a look at Miguels blog
The blogosphere's been talking about this issue recently.
Doug Putnam wrote up his experiences in installing Seaside (on Pharo) on his Slicehost slice, working off James Robertson's writeup (which uses VisualWorks, I suppose?).
