for a project i have to connect the Eclipse Leshan Client to a IoT Agent Server.
My problem is to read the device's mesurements with Postman or cUrl command.
The client after the configuration of the port (5683) look like it's connected to the server but i can't read the values of the dummy device.
I ask how i can connect the client to server. Which file have i to config for my work?.
Also i have set up an orion context broker on the port 1026. The listening port of the server is the port 5683.
I wish to use the devices registered in the client Leshan, but the data results EMPTY.

You need to take a workaround through that port in order to achieve your goal.
Best luck!
I have installed Firebird 3.0.1 on a PC and on a VM client. I installed Flamerobin on both to test the connection.
I can connect to localhost on both PC and VM using Flamerobin, so I assume the Firebird server is running on both and Flamerobin is installed on both OK
I can connect to the Firebird server on the VM from the PC and open a database Ok
From the VM I can open a database on the PC, but when I try to retrieve the server version on the PC I get an error ISC_Service_attach failed (Unable to complete network request to host).
I have no idea what the problem is given that I can open a database ok, but cannot access any of the utility services.
I am using fbclient.dll 3.0.1.32591 on both VM and PC
If you can achieve network request to server, you need to check firewall setings on server and set fb default port as inbound acceptable. If you would had same problem after that, than you probably need proper fbclient library, for FB3 on client, VM. Hope this helps.
I'm about to being developing an application that will connect to a Unix machine on a network (via internal IP). The machines that will be running this application already have access to connect to the Unix machine.
If I develop an ASP.NET MVC Web App running on an external IIS instance, will the web app be able to connect to a private local machine? I realise the IIS server won't (as it's private), but there will be locally executed code. Is this going to be able to access the machine? If not, I will have to resort to Windows desktop app.
You can use a VPN connection from an external server to the private network. Virtual hosting hasn't this feature, so you must use virtual machine.
A firewall software allows you to create VPN server usually, and any version of Windows allows you to establish a VPN connection to the server.
With a help of VPN connection your virtual machine can get ф private IP-address, and can access private network resources.
I have a local Ms access database in a local computer connected with internet with dynamic IP. And I have a java web application running on web server. How can I connect to Database in local pc with dynamic ip from the java application running on server
You would have to serve it from the client machine using either a local web server or a VPN tunnel.
Possibly a better idea (I mean, anything sounds better than connecting to a client-side DB, right?) would be to have the client upload the database (depending on the size) and then connecting to the server-side copy.
working under linux server Centos remotly in local network, my rails server working there too. How can I enable remote web access? And if so how can I enable only couple of ip addresses for web access?
You should check on which addresses the server applications binds. If it has no external IP-Address then it wont be possible to access it directly from the internet. Then it is possible to use port forwarding to forward your application over your router. If you havent any access to the router you should ask the administrator of your network to forward it for you.
Another possibility is to plug a VLAN to a secound interface but you should think about security when you have a server that is connected to your NATed network and the internet directly!
if its only rails production server setup then you can try with this:

it uses https://github.com/ballistiq/ruby-passenger-nginx-installer and they are maintaining the installer. I found its very helpful. it works like no-pain
