Analyzer network plugging
I am trying to see analyzer network plugging. It says that it has been installed but when I go through tools-analyze network... It does not allow me to click on it. It is there but inactivated.

I'm currently looking at options to allow me to build a remote COM-port solution.
The idea is to be able to access from my remote PC, another PC that's directly connected to a device locally via its serial COM-port.
I know that the obivous answer is to use a VPN between the 2 Internet connected PCs.
However, I need this solution to be as seamless to the end-user as possible.
i.e. no installing and configuring VPN software, etc.
So I was thinking that WebRTC would be great because the end-user can simply use their web-browser and not have to install any additional software.
My question is, is it possible to stream the COM port data between the 2 PCs via WebRTC?
If so, can you please point me in the right direction as to how I can go about achieving this?
Sorry if this is a ridiculous question, I'm very new to WebRTC, just exploring my options.
Thanks.
That should work great!
Networking wise you get NAT Traversal. That means the two computers can be in completely different networks, and still communicate. You may have to run a TURN server if P2P isn't possible.
Data wise you can exchange anything you want via data channels. It is datagram based and you can send/receive binary data. You get a callback telling you how much has been delivered, that way you can detect backpressure.
Are you ok with installing software on the remote host? You can do something like Pion WebRTC's data-channels. This shows you can have a browser connect to a Go process via WebRTC. Then use tarm/serial on the remote host to interact with the device.
If you want a browser on both ends there is the Web Serial API I haven't used it myself though. That locks you into only doing Chromium which might be an issue.
I'm currently using AutoHotKey to create a variety of macros. I have two desktops side-by-side in a private (home) network. It is my desire to have the AHK Run command on PC1 make some sort of call to PC2. Both PCs are running Windows 10 (non-domain), and both use the same login credentials (same account via microsoft.com).
What I've tried: I have tried a few things, such as WMI, WinRM, schtasks. Each of these options work when dealing with non-interactive scripts. I am trying to call scripts that a) open GUI windows or b) send key strokes to PC2.
Other requirements:
The solution cannot require the password to be type in a prompt nor provided in the command-line call. The desired effect is that I press a button on my keyboard -> ahk command triggers -> script on PC2 is called.
As this network is shared with roommates (and whoever they allow to connect to our wifi), basic security is still a necessity.
This is not a language specific question - I am looking for the simplest/easiest/cleanest method. Thanks for reading.
Try a remote access connection app like TeamViewer. They allow you to control one PC from another across a network. https://www.teamviewer.com/en/
I have an astronomical observatory in my yard with four computers connected to all the observatory equipment. These four computers are controlled over my home network from one PC in the house.
The remote access app allows you to run an .exe on another computer which in my case is usually a compiled AHK script.
I have a number of tasks that require several PC's. A script running on the main PC will start secondary scripts on the observatory PC'c which in turn will send messages back and forth by sending text files to each others shared files. The PC receiving the text file will perform a specific action based on the message.
Here's a link to the observatory startup procedure. I a startup script on the main PC which turns on all the observatory equipment then starts a secondary startup script on each of the observatory PC's to load and position all the software and then connect all the cameras and associated equipment.

This just shows how the various scrips running on the observatory PC's load and position all the various app windows. Not exactly what you may need but it may give you some ideas about what you can do with the remote access software.

Some friends and I are trying to create a game using the UDK 3. Right now it's nothing special; we've got a Pawn that spawns and moves around a custom map, and it's all written over the example game that comes with the UDK. I'm trying to get a dedicated server set up so we can test our changes (it's going to be a multiplayer only game). We're all on beefy Windows machines on the same network, and the server is not being run through Steam.
I've been using the Unreal Frontend to compile and package the game. The installer works fine, and the game it installs works as well. We can set up a simple peer-to-peer multiplayer game, and that works. The problem is when I try to run it as a dedicated server from the command line. The command I type in is
UDK.exe server provinggrounds.udk?bIsLanMatch=true
This executes and brings up a second console that says the game engine has initialized, and then waits. Unfortunately, none of the other copies of the game on the network can see this server, which is a problem. Now here's where it gets crazy.
I discovered this in the "try random things to see what works" phase of troubleshooting. If I run the game as a dedicated server from the command line, then open a second instance of the game on the same machine but in normal game mode, and then have that instance host a multiplayer match, any other instances of the game on the network will see one server and when they connect to it they will connect to the dedicated command line server on my computer. Once they join, I can close the normal hosting game without affecting the server, but then nobody can see the server anymore.
I really don't understand what is going on here. Why can't anybody's game find the server under normal circumstances? Why is the server only visible when there is a game instance hosting a peer to peer game on the same computer? Is there a way to fix this?
Try:
UDK.exe server map.udk?listen=true?bIsLanMatch=true?dedicated=true
That is what I use to launch a dedicated server. What you were properly missing was the listen=true part.
For more details see the documentation.
EDIT 1:
As a workaround you could force your game to connect to a given IP. In your game open with console with Tab and type Open #SERVER_IP# (replace #SERVER_IP# with the actual IP of course).
You can have your game connecting to a server passing the server's IP to it as an argument in the command line: UDK.exe #SERVER_IP#
EDIT 2:
Another problem might the firewall, perhaps UDK uses different ports when run as a dedicated server. Although unlikely, here are the ports that UDK needs to be opened/forwarded 6500, 7777, 7778, 7787, 13000, 27900 for UDP.
On my Win7-PC the network takes up to 10 minutes until it's shown as ready (through network icon). The weird thing is that even in the meantime (blue circle is spinning) network activities like mail, internet and access to network shares are working.
How does Win7 decide that a network is ready?
The issue is that one of my installed apps which uses the IP stack (runs on localhost) doesn't work until the network is in ready-state. I found out that if I disable the Windows Management Instrumentation service the network state switches to ready immediately. However, this prevents a couple of other services from starting what could lead to a security issue. (To me it seems like my PC waits until it gets a GO from our network... but no evidence here)
Any hints?
Try to apply this hotfix, sometimes it works:

When it happens to me I have to kill the process tree of two services:
SMS Agent Host
Winmgmt
(select the service, right click, select "go to process", right click on the process, select "end process tree"; if you cannot see the process remember to click the "show processes from all the users" button).
Finally delete the "c:\windows\system32\wbem\repository" folder as fast as possible.
The "repository" folder will be re-created and the network will start working properly.
This worked for me.
Click on run dialog and type msconfig.
In the pop up click on services.
Then check/tick Hide Microsoft services.
In the ensuing dialog uncheck/untick Nividia Network service.
Finally click Apply. restart computer.
Your problem will be solved.
Disabling NVidia Network services stopped that for me.
While updating drivers etc. is good practice, it is usually just a wild goosechase.
I've got a script that programmatically applies different proxy settings for different wifi networks, but I'd like to make it automatic; when a certain wifi network is logged into, my script is called with the network name.
Any ideas?
Assuming you are on a linux if-up/if-down hooks is what you need.
Look at /etc/network/if-up.d and /etc/network/if-down.d .
The interfaces(5) manual page whould help in general.
