Web app tcpping

Posted on 18.05.2021 Comments

I was working with a customer recently that put a website into Azure Web Apps. We created an Azure VNet and configured site-to-site connectivity that created a secure connection between the Azure VNet and their on-premises network. This would in theory allow the website to access their on-premises resources such as the database.

We also had to upgrade the site to Standard pricing in order to do this. We had to reconfigure the site-to-site gateway to allow dynamic routing in order to do this, which meant deleting and recreating the gateway. A bit of a pain, but not too bad. We then configured static routing from the on-premises network to the point-to-site addresses on the VNet. Once we had that all configured, we wanted to test connectivity.

If we had deployed a VM, it would have been simple — just open a cmd prompt and ping away. This became a little bit of a pain. However, I remembered reading about Kudu and decided to see if that would be easier.

So I tried it:. Looks promising! So I want to test if my site can reach my database server on portno problem:. Kudu saved us a lot of time! Ping from Azure Web App?

I have an Azure web app that has some Hybrid Connections setup. I'd like to be able to prove they are working from the KuDu cmd interface. Specifically I want to make sure I can relay to an email server, so telnetting to the port would be very useful. Learn more. Asked 4 years, 5 months ago. Active 4 years, 5 months ago.

Stefan Stefan 2 2 bronze badges. Hi, Yes that worked thank you. It does tell me there is an issue, I get the following. Connection attempt failed: An attempt was made to access a socket in a way forbidden by its access permissions PS Thanks so much for posting an alternative. You will need to use a hostname rather than an IP address - IP addresses in Hybrid Connections are not quite reliable and depend on how the underlying framework is implemented.

As for tcpping, it may not work as a proof of concept - there's a local port on the Web App that does the relay, and tcpping will only test connectivity to this port. We are working on better debugging tools for Hybrid Connections. That's great insight thank you. We're going to try the host name instead of an IP address. I look forward to better debugging tools, sounds great.

Added ability to save and load ping site lists Added ads and an option to turn them off. I use this constantly when troubleshooting connectivity problems with Windows 8 apps. Saved settings make it quick and easy. This is a nice start for a ping app, but it's missing several key features: reset stats without quitting the app ; standard deviation; ping an IP address currently DNS name only ; favorite addresses; trend charts and drop rates over a longer time; histograms.

Why it can't ping internal device???? Please: - Add option to set animation velocity - Themes - Chart type lines, bars, overlapped charts Very nice app that is quite eye-catching and useful since it can simultaneously ping different machines and display on a single screen. Portrait view with ads is poorly designed. I need to ping servers which are behind a firewall exactly what this app states to do.

We created Local network gateway with IP adress of on-premise device and subnet Then we created VPN connection Ipsec to this device. Connection is Succeeded and Connected, traffic working ingress bytes; egress bytes.

But we have problem with ping from AppService. Ping on internet www. I was looking for firewall to setup but no firewall existing. On on-premise side we see coming ping from Problem in tcpping was firewall. I turned firewall on and set rule and tccping works. I integrated VNET with app service again, set other deleted things and wuala, everything works.

Have you integrated the App with the Azure Virtual Network as outlined in this document? You could checkout the suggestions outlined in this document section Troubleshooting and see if that helps.

Answered by:.Whether it is a Web Server or any local computer, if you really want to check its availability then there is a way to do it. A common way to do this is PING. If it accepts it then the connection is approved else you get a Timeout error and that tells you it can't connect with them.

Then, we ask for a response from the pinged device or server. For this, we need to use the Send method and we two arguments within it. First will be the Host Name and then the timeout time.

NET 5.With Azure Virtual Networkyou can place many of your Azure resources in a non-internet-routable network. The VNet Integration feature is used in multitenant apps.

If your app is in App Service Environmentthen it's already in a virtual network and doesn't require use of the VNet Integration feature to reach resources in the same virtual network.

For more information on all of the networking features, see App Service networking features. VNet Integration gives your app access to resources in your virtual network, but it doesn't grant inbound private access to your app from the virtual network. Private site access refers to making an app accessible only from a private network, such as from within an Azure virtual network.

VNet Integration is used only to make outbound calls from your app into your virtual network. The VNet Integration feature behaves differently when it's used with virtual networks in the same region and with virtual networks in other regions. The VNet Integration feature has two variations:. Gateway-required VNet Integration provides access to resources only in the target virtual network or in networks connected to the target virtual network with peering or VPNs. Gateway-required VNet Integration doesn't enable access to resources available across Azure ExpressRoute connections or works with service endpoints.

Regardless of the version used, VNet Integration gives your app access to resources in your virtual network, but it doesn't grant inbound private access to your app from the virtual network. Private site access refers to making your app accessible only from a private network, such as from within an Azure virtual network.

VNet Integration is only for making outbound calls from your app into your virtual network. Under VNet Integrationselect Click here to configure. The drop-down list contains all of the Azure Resource Manager virtual networks in your subscription in the same region. Underneath that is a list of the Resource Manager virtual networks in all other regions. Select the virtual network you want to integrate with. During the integration, your app is restarted. When integration is finished, you'll see details on the virtual network you're integrated with.

When you use VNet Integration with virtual networks in the same region, you can use the following Azure networking features:.You can even use multi-container deployments using Docker Compose or Kubernetes. Note: Bookmark this post! I update it frequently as we uncover issues and as our Linux offerings evolve. General Information If a feature is disabled in the portal, it's not available on Linux.

If you don't see a feature you want, you can request the feature. To prevent down-time when you update your code, use Continuous Deployment.

If you change your Docker container, it may take a minute or so for it to take effect. Custom images are stored on disk unless a worker change happens. Continuous Deployment requires that the image:tag combination remain the same. Multi-Containers We have a great tutorial on multi-container deployments. You need to understand the concept of the "web" container. You can explicitly set the web container using an app setting. All containers must start or Web App startup will fail.

All images must use the same registry. If you're using Azure Container Registry, you need to set some app settings. Configuration You can enable and disable storage persistence with an app setting. App Settings are injected into your app as environment variables at runtime. Some characters may be stripped out of environment variable names. App Setting names are limited to 64 characters Your environment variables won't appear in the Bash console.
