If anyone else runs into this issue, I just wanted to clear up the solution: I went through all the settings available to me on azure, and the only way to solve this issue was to remove the VM from all Security Groups, thus disabling the Azure firewall. The Azure DNS does not affect the filtering. The connection with RedSys works now by using an internal ...

Leave the swap at 6GB. If it worked before with 8GB+6GB it will also work with 16GB+6GB. More info here: http://askubuntu.com/questions/62073/how-to-decide-on-swap-size

You are limiting incoming connection to port 80 only. Client browsers can use a port number ranging from 1024 and 65536 for their outgoing connection. You need to change your security group settings to allow incoming connections from Any port: allow-http source: any source port: any dest: any dest port: 80 service: tcp/80 action: allow ...

No, this is not a good idea. If you want to run VMware and have RAID protection, you need a supported hardware RAID solution. Please see: Software RAID underneath ESXi datastore

It looks like all the answers share something like these options in common: -x lan: Let rdesktop know you have a good connection -P: Let rdesktop cache bitmaps -z: Let rdesktop use compression

Instead of specifying "any" against 'destination port' in both of your rules, you need to specify port "80" and "443" as destination ports. With that, when you put http://MY.PUBLIC.STATIC.IP your traffic will reach port 80; and when you put https://MY.PUBLIC.STATIC.IP your traffic will reach 443. From this Microsoft's link, check the sub-topic 'NSG for ...

I'm not sure if this is worth keeping alive for others, but it did end up being an obvious error, bar.dev didn't have its listen 443 ssl;, it had two listen 80;s. So a working bar.dev config: upstream bar_upstream { server 127.0.0.1:4000; } server { listen 80; listen 443 ssl; server_name www.bar.dev; ssl_certificate /etc/ssl/bar.crt; ...

Yes. VMWare shares the CPUs/cores by default. When an ESXi host runs multiple virtual machines, it allocates to each virtual machine a share of the physical resources. With the default resource allocation settings, all virtual machines associated with the same host receive an equal share of CPU per virtual CPU. This means that a single-processor virtual ...

You can set each VM to have up to two cores in this case. The more cores the more wait time per processing task. You can certainly assign two cores to each VM but it wont help them. As for memory, you don't want to oversubscribe it too much. My suggestion is to leave 20% for host and distribute the rest. You can monitor memory and change it so that you're ...

By default Linux VMs don't have any swap enabled... When you fire up a VM, a random "compute node" is chosen that has the capacity for the size of the VM that you chose. Compute Node, is just a highly modified machine with Hyper-V installed. Your OS disk; /dev/sda is not local to that server, and therefore not as fast as local storage. (and also subject ...

OK, I was trying to avoid this, but couldn't wait: I removed the Ubuntu VM from the subnet (adding to another), restarted, returned to the same subnet, restarted again, and voila! The communication was restored. It's odd that you have to do this kind of nonsense movement as a last resource...

Yes it's possible to do this. The technology you are looking for is called Name Based Virtual Hosting.

I'll just put this here in case someone else needs it cause I literally just stumbled upon the answer now through trial and error, after an entire day of troubleshooting this issue.

If you have assigned Instance Level Public IP Address(ILPIP or earlier known as PIP) to your instance then you won't be able to restrict the inbound traffic unless you configure that particular instance's OS level firewall or create NSG because the sole purpose of ILPIP is to receive traffic from external sources on dynamic ports meaning anyone can send data ...

There are excellent V2V Converters like ones StarWind and 5nine do but in your case you only need to a) export and b) import VM. See link below. Overview of exporting and importing a virtual machine (TechNet)

Yes. By default, nginx will cache the request body. So if you're uploading 50 GB across 5 servers then your reverse proxy will have to store all 50 GB. (assuming the uploads are going on at the same time) You can disable this using the proxy_request_buffering directive. Read the documentation for details on how to configure it as there are some limitations: ...

While WSUS is certainly a good solution for the servers that you manage at your site, it's going to be complicated/difficult to make that work for your clients that have servers at their own sites, unless you deploy WSUS at their sites. You might be better served by investing in an MSP product that's more suited to your needs, such as Kaseya VSA - ...

WSUS is definitely what you are looking for. It can do everything your looking for in terms of updates including requiring you to approve updates and allowing different update groups. You'll need to look for a different solution for the imaging however products such as veeam or other backup solutions for virtual systems will usually be able to do this. ...

Your post is moderately unclear. I don't think you're referring to nginx fastcgi caching, but you could be. Nginx does what you tell it to do. If you're using proxy_pass then my understanding is it just passes the connection to the next server, it doesn't receive the upload then send it on itself. ie nginx acts like a connection proxy. If you're talking ...

Trying to have apache pass SSL to another server serving SSL is more trouble than it's worth. You're better off having it handled at the main apache server. It's just easier that way. Here's an example of what I've done for one of my five subdomains. I've taken out any extra configuration options that aren't relevant to your question. <VirtualHost ...

Export the VM. Import it on the new machine. You'll probably have to specify a few things like the network switch when you import.

I would absolutely saying you need to go to a config management solution, because I would consider that the professional solution. My preferred one is Ansible because its pretty easy to learn and setup, and requires only ssh access to servers. Ansible has a git module that can clone a repo to what ever directory you require, and you can copy a private key ...

Too long for a comment: Port 990 is for implicit SSL and implicit SSL is deprecated. You should be using explicit SSL as described in RFC 4217 which will use the regular FTP port to establish a control connection, TCP 21 and then upgrade to TLS. Opening up a single port is going to be insufficient for FTPS as the protocol is exactly like regular FTP ...

I found the solution myself - I had to go in to the new Azure portal and reset the logon password to the same one I supplied when creating the new VM. Then I restart it from the portal and problem fixed!

Definitively, you should use Azure Automation to run on schedule a PowerShell Script to shutdown or start your VM in Azure. It is already well documented on Microsoft Web site. Here are 3 links that explains step by step how to do this Stop Azure Virtual Machine using Azure Automation Runbook ...

There is a Service Management API call that will do it for you using REST (assuming you are using classic VMs). For some reason, this wasn't implemented in the PowerShell cmdlets (perhaps you can contribute :) ) Have a look at Shutdown Roles This API can Shutdown (and optionally deallocate) one or more VMs at a time. <ShutdownRolesOperation ...

You should just need to sysprep any machines you imaged with the un-sysprepped image. Make sure to take an image of one of these to use for a new standard image (This will need to be done after you sysprep and before you boot the system back into the OS for the OOBE or automated configuration.

I presume you are connecting to the Azure VM through RDP. If so, what you are trying to do is not possible. If you want something like the above, one way would be to connect your Windows 7 machine and Azure VM, both, to a VPN connection. SMB based file shared does not work (reliably) over just the internet, mostly because ISPs block SMB ports for security. ...

You can use any server in a datacenter to run a scheduled PowerShell script. Mark Hick has a good post on doing all of this https://www.petri.com/manage-scheduled-tasks-windows-8-windows-server-2012-powershell-part-2. I would add to this that you'll want to pass in login parameters, and if you want to shut everything down on one server then something like ...

Your domain registrar should have a control panel which allows you to alter the DNS settings for the domain you have purchased. You will want to alter the A record to be the public IP of your VM (and/or the AAAA record to the equivalent IPv6 address, if you have one). There may be options to delegate the DNS to other nameservers but that's not what you're ...

Assign an EIP to your EC2 instance, then create the DNS record you need (probably an A record for the host @) and point it to the EIP.

Usually, the answer is "no", unless the virtualization platform explicitly provides this kind of information to its guest systems (which is not a common occurrence). You can detect which platform is in use (VMware, Hyper-V...) by examining the list of virtual devices in the guest system and their drivers, and also by checking if platform-specific guest ...

There are a number of solutions to this You could have a Powershell script in Azure automation, that will connect to your subscription(s) and shut down or start up the servers dependent upon a parameter. You could then have a webhook attached to those servers, that you can connect to a HTTP Post button somewhere to stop or start them. Or you could do a ...
