The connection to the Azure Percept DK access point frequently disconnects. How to know the root cause of this problem and resolution.
This can be due to a poor connection between the device and the host computer. It can also be caused by interference from other Wi-Fi connections on the host computer.
Make sure that the antennas are properly attached to the dev kit. If the dev kit is far away from the host computer, try moving it closer. Turn off any other internet connections such as LTE/5G if they are running on the host computer.
The connection to the dev kit access point should get more stable with an upcoming operating system refresh. Users on the private preview dev kits should install the update as soon as it is available.

I would like to connect a volttron platform running on a raspberry pi connected to the local network of a building to a second volttron platform running on a virtual personal server.
I know that two volttron platforms can interact with each other using the Volttron Central Management Agent or using the ForwardAgent. However, it is not clear to me what security method is used. Our ICT manager only agrees to set up a connection if the information is exchanged through https.
Could you help me formulating an answer to ICT regarding the security issue? And give me some pratical tips on how to set up the volttron configuration files? I'm not very familiar with network/security technologies. Maybe important to know: the server has a proxy and a reverse-proxy security.
Thx!
Your security person is correct. You should only set the platform up in a "real" environment through https. Since you have a proxy, that should be forwarded to the volttron central agent.
internet (443) -> proxy -> http://127.0.0.1:8080
The proxy in this case is on the same machine as the volttron central platform.
This is how we are doing it with apache as our proxy. One could do the same thing with a different web server such as nginx.
Hopefully that helps
If you are indeed trying to connect from a single instance to another instance (e.g. the way the forwarder does). Then the answer is the security is using public/private key pairs with curve mq providing perfect forward security. All traffic between platforms is 100% encrypted and only authorized agents can transmit across the instances bus.

I want connect to a remote computer (windows server 2012 data center) using team-viewer but remote desktop connection should be opened and connected when I want use my team-viewer for connecting to server team-viewer. if not, team viewer in my computer returns this error:
After reconnecting to remote using windows remote desktop connection, I can see the screen again without this error. What should I do to connect team-viewer directly to server without active remote desktop connection?
You also could change some settings so that the user is allowed to stay actively logged in (as was the case in previous windows server versions).
The topic below describes a case where idle users were logged out, it was suggested to disable windows settings so that the user session would remain logged in.
https://superuser.com/questions/558920/disable-windows-server-2012-automatic-log-off
This happens because of the following reasons.
If you RDP (and then you minimize the RDP session, or let go of it)
Log out of the user that has the Teamviewer open
Let the PC idle out.
Solution to override this issue.
INSTALL TEAMVIEWER AS A SERVICE - Turn off your quick-run/quick-support of teamviewer and go to www.teamviewer.com and install the program to launch on boot (that will install it as a service), you will see the option for that during installation. Then that error will never turn up, even if your RDPs. If its already installed, here are the instructions on how to make it run as a service.
I am using JDBC to create a connection to an MS SQL Server Database. The same code and connection string works fine on a number of platforms and in particular in my spring MVC Web Application.
After deploying the web application to a remote tomcat hosting service, everything appears to work fine in the code except that the database connection times out.
"com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host <IP Address>, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall."
The hosting company says I must provide the exact steps to recreate the problem which may not be ideal. The only thing I can think of is to write another cut down application that connects to a different db with different credentials and test that in dev and deploy and then email them the war so they can deploy it and test it in their own environment.
Does anyone know of reasons why this might happen with a hosting service, like blocking the database response for some reason? Or is this very unlikely and should I assume that I am doing something wrong and persevere in understanding what might be different between my dev app and deployed app that could cause this timeout. Not that I can think of anything.
I don't want to take all that time if there is a common reason why this might happen that someone could point me to.
Thank you.
I have developed an application using sql anywhere database as back end and powerbuilder as front end. it is working on my laptop very well and i have also used this app on network server (without internet ) using wifi on another laptop. in which the program is installed on that other laptop and it connects database stored on my laptop .
now i want to develop a mobile app which should connect to my laptop and use database stored on it. It should connect the database using WIFI network.
i have knowledge of powerbuild simple programing, SQL and Visual basic. but i dont know any thing about mobile app developing.
Please help me to solve my problem.
This shouldn't be too challenging, it sounds like you want the app to connect to a network (or your laptop) database vs. the client machine like any web application and this shouldn't be a challenge other than making sure you've opened up the proper ports for the database in windows firewall AND/OR if you are on the INTERNET you'll probably need to set up port forwarding on your local router so that the database requests to your laptop from the "internet" get forwarded from your router to your local subnet (network).
So for example mySQL uses port 3306 (I think.. memory?) so you'd need a port forward in your router that forwards incoming 3306 requests to your laptop IP address, mac address, or machine name (better to use machine or mac).
HTH
I got a question here. Seems a little complicated in my mind. Hope I can make myself clear. :)
I have a Win7 system (system A) with a Win7 VM (system B) running on it.
System B is connected to a intranet through VPN to log some realtime data into a local sql server database. Internet connection is disabled by administrator so System B is separated from outside.
Now System A wants to connect to this database and read these realtime data.
Is it possible?
I don't have any experience with vmware, but assuming you can use any VM, here's a solution for VirtualBox:
Setup a network interface on your VM, that's visible to the host
system only (reference):
Host-only networking is another networking mode that was added with
version 2.2 of VirtualBox. It can be thought of as a hybrid between
the bridged and internal networking modes: as with bridged networking,
the virtual machines can talk to each other and the host as if they
were connected through a physical ethernet switch. Similarly, as with
internal networking however, a physical networking interface need not
be present, and the virtual machines cannot talk to the world outside
the host since they are not connected to a physical networking
interface.
Configure port forwarding on system B ([external_port] -> [host_over_vpn]:[service_port])
Connect to [system_B_ip_over_provided_interface]:[external_port] as if you were connecting to the database directly.
yes it is possible. Just give correct IPs.
