I setup an Ethereum private-net that help me deploy, testing smart contract locally. I just want to have a UI can deploy smart contract and visually testing assets transfer.
I think Mist is my first choice. So I want to know how to configure Mist redirect to my private-net. If not, do you have any other recommendation?
Thanks!

I'm new to web development and just built my first website with .Net Core. It's primarily HTML, CSS, and JavaScript with a little C# for a contact form.
Without recommending any service providers (question will be taken down), how do I go about deploying the website? The more details the better as I have no idea what I'm doing haha.
Edit: I am definitely going to go with a service provider, however the business I am building the website for doesn't have a large budget so I want to find the best provider at the lowest cost.
Daniel,
As you suspect, this is a bit of a loaded question as there are so many approaches. One approach is to use App Services within Microsoft Azure. You can create a free trial Azure account to start that includes a 200.00 credit, which is more than enough to do all of this for free. Then, using the Azure Management Portal, create an App Service (also free) on an App Service Plan in a region that makes sense for you (i.e. US West). Once you do that, you can download what is called a Publish Profile from within the App Service's Management Portal in Azure.
If you're using Visual Studio, for example, you can then right click your project and "Publish" it (deploy to the cloud, or the App Service you just created). One option in that process is to import an Azure Publish Profile, which you can do with the one you just downloaded. This makes it really simple. The Publish Profile is really just connection information to your Azure App Service (open it in Notepad to see). It will chug for a bit and then publish and load the app for you. You can also get to the hosted version of your app by clicking the Url of the app in the App Service management portal on the main page.
This may be oversimplifying what you need to do, but this is a valid direction to take. AWS and others have similar approaches.
Again, tons of ways to do this, but this is a free approach. :-) I don't consider Azure a Service Provider in the sense that you asked us not to. Instead, I wanted to outline one turn-key approach with specific details on how to get there.
You can find specific steps in a lot of places, such as this link:
https://www.geeksforgeeks.org/deploying-your-web-app-using-azure-app-service/
DanielG's answer is useful, but you mentioned you don't want use any services from service provider.
Usually, there are only three ways to deploy the program,
first one is the app service provided by the service provider mentioned by DanielG,
**Benefits of using service provider products:**
1. Very friendly to newbies, follow the documentation to deploy the application in a few minutes.
2. It offers a very stable, scalable service that monitors the health of our website.
3. We can get their technical support.
**Shortcoming**
It is a paid service, and although Azure's service has a free quota, it will run out.
**Suggestion**
It is recommended that websites that are officially launched use the services of service providers.
second one is to use fixed IP for access (it seems that fixed iPv4 IP is not provided in network operations),
**Benefits of using fixed IP:**
If there is a fixed IP address, or if the carrier supports iPv6, we can deploy our website, and the public network can access it. And if you have domain, it also can support https.
**Shortcoming**
1. There are cybersecurity risks and are vulnerable to attack.
2. Without perfect website health monitoring, all problems need to be checked by yourself, and it is very troublesome to achieve elastic expansion.
**Suggestion**
It is generally not recommended because there is no fixed IP under normal circumstances. Broadband operators used to offer it, but now it doesn't.
If you are interested, you can try ipv6 to test.
the last one is to use tools such as ngrok or frp for intranet penetration.
**Benefits of using intranet penetration:**
Free intranet penetration services such as ngrok, the URL generated by each run is not fixed, and there are some limitations, such as a new URL will be generated after a certain period of time, which is enough for testing.
Of course you can purchase the service of this tool, which provides fixed URLs and supports https.
**Shortcoming (same as the second one)**
**Suggestion**
The functional implementation is the same as the second suggestion, and the physical devices used by the website are all their own. The intranet penetration tool (ngrok, or frp) solves the problem of not having a fixed IP, providing a URL that you can access.
There are few users and the demand for web services is not high, so it is recommended that individual users or small business users use ngrok and frp in this scenario. Generally suitable for OA use in small businesses.
Need help migrating upgradable smart contract on tron network.
I have created smart contract and trying to use the openzeppelin’s proxy contract to migrate it as upgradable. But the migrations are not working as expected and upgrades are not working
Can somebody help?
I created a simple Vue.js application. I am trying to deploy it on Google compute engine(not app engine or any other), but I can't find any appropriate solution. Can anyone help me?
Have a look at App Engine. It'll be the easiest way to deploy your app without thinking about infrastructure management.
If you really want/need to use Compute Engine you should decide on your own which OS to use and then install and configure all the required software manually.
Meanwhile, I should mention Cloud Run as managed compute platform that automatically scales your stateless containers with your code.
Please update your question if you need more details.
Deployed using express server, Nginx and pm2.
Advanced Attacks Detection in a Platform-as-a-Service(PaaS) Environment
In the first part of this project, i'm supposed to monitor incoming packets
in a web service, accept only HTTP & HTTPS (TCP)packets for later analysis and, drop the rest.
I was thinking doing this in JAVA, because i think it's a very flexible and
complete language and, it's present in every PaaS Environment! So, my idea is
to build a simple web page in JSP/JSF with a bean to attend this first step
of the project.
This is where i need some guidance! Because i've started considering
libpcap JAVA wrappers like jNetPcap, Jpcap and Pcap4J. But none of them is able to drop packets!
Forgetting JAVA, i also have red about other libraries like: libnet, libdnet and libcrafter.
libnet can not handle the task!
libdnet has network firewall rule manipulation capabilities, but it's a very old library and, i'm not sure it can handle integration with iptables!
libcrafter is the best! Because it's an actual updated project and, it allows the use of iptables rules in the code.
And, of course, working directly with netfilter would be the ideal scenario!
But working with libcrafter or netfilter, to follow my simple idea of a web service with a JAVA bean, i would have to write my own java wrapper by JNI! Which i assume NOT to be a simple task!
Now, what is raising many doubts in my mind, is the fact that this has to be
done in a PaaS environment! None of them (PaaS providers) seem to have the
same restrictions. There are some more flexible like AWS and Microsoft Azure that let you choose and manage a VM with the OS distro you want. Others like OpenShift, BlueMix or Cloud Foundry, in a project, only give you the option of defining the programming language, application server and, that's it! So, one might not have permissions to install libraries and control network & transport layers to manage the packets! Since the hole OS administration is handled by the provider.
Considering only the main purpose of this project, which is managing the packet flow pointed to a domain located in a PaaS environment, without the help of other servers like tcp proxies, i am desperately in need of someone pointing me a direction to start from! Because with that, i can dig as deep as needed to get a solution. Please HELP!
Thank you very much for your time and consideration.
Need to access Dialup terminal transnational history
I'm a software engineer and thus far my world has been on the internet. So any payment processing I've ever doen has been through Gateways (Auth.net, SecureNet, ...etc) However I have a new project that requires me to deal with physical terminals. Some terminals that are linked to WiFi or Ethernet are exactly the same they just go through the gateway and and the backend API continue to work. Dialup terminals are apparently different and skip a gateway all together.
Does anyone know how I can get a dialup terminal's transactional history via some backend API?
So I called up the gateway (securenet) and they are telling me that I wouldnt get terminal transaction history via the API. This was confusing because the API documentation states if there was a pin pad on site which would imply a terminal.
I also called up a terminal programming firm. They assured me that even if they wrote custom software to the terminal it still wouldnt have access to the transaction unless it was the processing software itself.
so the answer is I'm SOL
