i am trying to link two Microsoft Azure Linux virtual machines through ssh connections. When I tried with
$ssh 10.0.0.7
To connect to your Linux VMs you need a public-private key pair (SSH keys) which can be done by following this documenation to create your SSH keys if you haven't done so already. Once you have your SSH keys you can SSH to your VM using the IP address or DNS name of your VM. You can follow the steps in this Azure tutorial to connect your Linux VMs.
Alternatively, you can try using Virtual Network Peering via the Azure portal. You can connect virtual networks to each other with virtual network peering. Once virtual networks are peered, resources (including VMs) in both virtual networks can communicate with each other, with the same latency and bandwidth as if the resources were in the same virtual network.

I'm newbie to OpenStack! I've installed Openstack in Ubuntu Server 18.04 LTS on Microsoft Azure virtual machine (for my learning purpose because I don't have the required resources like 16GB RAM and 4 CPUs). I'm able to access the Openstack Dashboard with the help of public ip address of that VM using the browser in my machine. I've assigned floating ip address to the instance (here it is 172.24.4.8).
My instance specs are
This is my network topology and my azure virtual machine's network configurations
azure vm's private ip = 192.168.0.4
azure vm's public ip = 20.193.227.12
I can access the OpenStack Dashboard using azure vm's public ip address, But I'm unable to access the instance via SSH from my local machine and from that azure virtual machine too. Help me how to access them!
From your network topology screenshot, I guess that you used Devstack to create the cloud. Can you confirm that?
The external network named public is not connected to the world outside the cloud in any way. This is so because by default, Devstack creates an isolated external network for testing purposes. You should be able to access the instance from the Azure VM, however. The information given is not sufficient to explain why you can't.
See the Devstack networking page. It states that the
br-ex interface (...) is not connected to any physical interfaces
This is the technical reason for not being able to access instances.
The Shared Guest Interface section of the above page documents how to connect a Devstack cloud to a real external network.
EDIT:
The Shared Guest Interface instructions ask you to set this:
PUBLIC_INTERFACE= NIC connected to external network. *eth0* in your case.
HOST_IP= *192.168.0.4* for you
FLOATING_RANGE= Your netmask is 255.255.255.128, which translates to a network prefix of 25,
I think. If I am right, the value is *192.168.0.0/25*.
PUBLIC_NETWORK_GATEWAY= The IP address of the router on the *192.168.0.0/25* network.
Q_FLOATING_ALLOCATION_POOL= The range of addresses from FLOATING_RANGE
that you want to use as floating IPs for
your OpenStack instances.
FLAT_INTERFACE might be an old setting for the defunct Nova-Network service. I don't see it mentioned at all in the Ussuri version of Devstack.
I have a Vm from Azure and in that vm I have another vm running in Hyper-v. That vm in Hyper-v is running a Ubuntu Linux (64 bit) guest operating system, with a virtual appliance. When I run it and it is finished booting, I'm given a IP address like this: "https://10.8.40.104/4442". The problem is I'm not able to access it from inside my 1 vm from Azure. I tried pulling up the browser and pasting the address, but nothing. I am quite new at this so its possible the solution is fairly simple.
Anyone have any idea how I can access that static IP address?
To install Hyper-V in Azure Nested Virtualization, you could follow steps in this blog:
There are (7) short steps that need to be completed to provision a
nested virtual machine inside Microsoft Azure:
Create an Azure VM capable of nesting (Windows Server 2016, etc)
Connect to the Azure VM
Install Hyper-V Feature inside the Azure VM
Create a NAT’ed vSwitch for outside connectivity
Create the guest virtual machine
Configure an IP Address on the nested guest virtual machine
Test Connectivity
For allowing connectivity to the nested virtual machine from outside, you need to create a new virtual switch that will be configured for NAT’ed access. The network flow will be like this: outside---host public IP---host private IP---NAT internal switch---Internal gateway---nested VM private IP.
Feel free to let me know if this helps or need further help.
I have two virtual networks (classic) in Azure, and I need to be able to ssh between vms on these networks. I have followed the instructions here (https://azure.microsoft.com/en-us/blog/vnet-to-vnet-connecting-virtual-networks-in-azure-across-different-regions/), and successfully connected the networks. However, when I try and ping vm1 on vnet1 and vm2 on vnet2 the request times out, so it looks like vm1 cannot see vm2. Are there any further steps I need to take to allow communication? Shouldn't they be able to see each other's private IP addresses?
That's a pretty loaded question, but I think there is a better walk through for you to have a look at:
Configure a VNet-to-VNet connection in the Azure Classic Portal
or
Configure a VNet-to-VNet connection for virtual networks in the same subscription by using Azure Resource Manager and PowerShell
Pick your poison... I've verified both of these work as intended if you follow the steps carefully.
Scenario:
I have a website on Windows Azure. That website needs to connect to a (new) Azure VM.
I have done the following:
Created new Virtual Network on Azure
Added the VM to the Virtual Network, and it does get an IP in the virtual network.
I have configured the appropiate Endpoint for the VM (Public/Private port).
Now, how do I "connect" the Azure website to the same virtual network, such that my .NET code in the website can create a TCP connection to the VM on it's IP on the Virtual Network ?
This is now possible. Be sure to use the NEW Azure Portal. For details, check out:

Currently you cannot connect/add Azure Web Site to a Virtual Network. You can only add VMs and Cloud Services to a Virtual Network. However this is a demanded feature and I believe we will see it in the future releases of the Web Sites service (my speculation).
The key here is to create the Virtual Network before the Virtual Machine and then place the VM in the VN during it's creation. The article here gives instructions moving a VM into a VN.

I am trying to connect my Windows Azure Virtual machines to my On Premise network. I have established a site to site VPN tunnel, and have created the appropriate subnets and placed a virtual machine in one of the subnets that isn't the gateway subnet.
My on premise test network is 192.168.9.x/24 my Azure Network is 10.4.x.x/16 with a subnet for DMZ - 10.4.2.x/24 and ServerNetwork at 10.4.3.x/24.
I have confirmed that the tunnel is up and running both on the Windows Azure side, as well as on my Cisco ASA 5505.
I want my servers to be able to communicate across the tunnel, however currently they cannot see each other. I am missing something, I tried static routes between the two servers, and have not had any success. Has anyone gotten this to work? If so what did you do on the networking side of the config to make it work?
Thanks,
Steve
Windows Azure Virtual Network enables you to create secure site-to-site connectivity, as well as protected private virtual networks in the cloud.
You can specify the address space that will be used for both your virtual network and the virtual network gateway.
Additionally, new name resolution features allow you to connect directly to role instances and virtual machines by hostname.
These features allow you to use Windows Azure as you would a branch office, or as a protected private virtual network in the cloud.
You can read more about it here:

Here is a lab exercise to walk you through the process:
