I want to use terminal/console of ubuntu 14 installed on virtual machine running on cloudstack 4.6. I am able to use ubuntu 14 desktop normally but whenever I try to use the terminal from it, i get "Client communication error please retry later". Following is the screen shot of the error.

I am using college network behind a proxy server, could that be a problem ?
any suggestions ? Does anybody know where I am going wrong ?
Quickest way to troubleshoot this - on the browser window that houses the broken terminal, do a view source. In there you'll find a URL direct to your console proxy server. Copy and paste that URL into a new window and see if you can hit it directly. I'm guessing a firewall issue...

Hey this is my first question on here, so go easy.
I set up a Nextcloud server on my homelab in an ubuntu server 20.04 vm using the snap install. I have a seperate vm running nginx as a reverse proxy to my Nextcloud instance. Everything works flawlessly as intended, except that when I try and install apps on Nextcloud, I get a curl error #7. I've tried using my lan ip through the web ui, my public domain name through the web ui, and the commandline using the nextcloud.occ app:install command. I always get the same error. I tried to find the appropriate log file to get more information but looking in /var/snap/nextcloud/current/log/ I couldn't find any relevant info in any of the logs. Running php -m comes up with php not installed, I guess because php is installed via the Nextcloud snap? Obviously php is installed somewhere because Nextcloud is running, but I don't know how to look and see what modules are enabled, or how to install new ones using the snap. Any help on what to do is much appreciated!

Update: I fixed it. I think I had improperly configured my firewall, and turning it off (in proxmox)/making some changes to my /etc/netplan/*.yaml file to properly configure the static IP fixed it. GL
Another reason can be a wrongliy configured network. I forgot to set the gateway/proxy for IPv4, so github.com was unreachable. Most other services I use seem to resolve IPv6 first, so I did not have any other problems besides updating nextcloud apps.
TCP connections work fine as I am able to converse with someone over zoom and teamviewer. However, whenever I attempt to access another webpage, I get a network error. Google seems to work fine for some reason but any webpage I go to listed by Google fails to connect. The only way I can open up my http connections is by ending a task called "init" inside of task manager. This shuts down my vscode as well as my ubuntu terminals I have running. If someone knows the solution please do tell. It's really annoying having to close out my vscode and terminals as well as my local servers to look up information and debug.
I found a fix to this issue.
So I was running a Windows Subsystem for Linux and my Windows Build was outdated as well as WSL. When I updated Windows and upgraded to WSL2, my issue was resolved and I don't seem to get any more network errors.
I have an API in a .NET project that I'm running with Visual Studio Mac (8.4.3). I run it in release mode, and it opens a browser window with localhost:5000. The browser window says "ok". However, when I try to hit endpoints in that API, it fails very quickly. When I ran this API (ie. same code) from another server and accessed it via proxy, it ran fine. For example, when I ran it on a server whose IP was 162.250.198.98 and proxied into it, I would hit an endpoint like 162.250.198.98:3000/api/user and it would work, but now when I try to run localhost:5000/api/user, either from my app or from Postman, it fails almost instantaneously. When running it in Postman, I tried what it suggested by turning off 'SSL certificate verification' in Settings, but no change.
Can anyone advise me on how to approach troubleshooting this?
Wait, so You are saying that while trying to call API on 162.250.198.98:3000/api/user You are fine but while trying to do the same thing on localhost:5000/api/user You are getting an error? Would it might be possible You have Your API configured to receive calls at 3000? :)?
No, but really - please chech it out, maybe it is that simple, I'm couting on it :).
You can change/check it in Visual Studio: main project > Properties > Debug > App URL.
I downloaded the Teradata express VM today. But I don't use vmware... i use virtual box instead. I created a new VM and added all the vmdk disk files to virtual box.
but it is throwing error could not find /dev/disk/by-label/ROOT-BE1. Want me to fall back to /dev/disk/by-path/pci-0000:00
does anyone know how to boot the vm image with virtual box?
I have the same problem, with the same message. The same mistake.
The solution is simple. Just change the Storage Controler to SCSI. After this, restart the VM and it will start normally, but in command line.
I try, but i can't run the startx command...
Try adding IDE controller and then add the disk as existing hard disk device. This should let you boot into the OS.
I saw this exact error when trying to load the VM in KVM. What seemed to fix it was selecting 'single user mode' in the grub menu. After booting like this once, selecting the default grub option subsequently allowed the VM to boot further than this error.
Note that I haven't been able to successfully bring up the actual database yet - the service doesn't start automatically, and when I start it manually, it reboots the VM, bringing me back to the same state as before. Maybe you'll have more luck with VirtualBox?
I'm trying to setup automated GUI tests in ESXi Virtual Machines using TestComplete. The problem, as I understand it, is that when no remote desktop connection is made to the ESXi virtual machine, then it is impossible for TestComplete to perform screen captures and therefore automate the GUI testing. As far as I understand it, this is due to the fact that Windows does not generate any user interface when nobody is viewing it.
I'm sure other have experienced this problem. How did you solve it ? Are you using a third party computer which automatically launch remote desktop connections prior to running the tests ?
Would it be possible to launch a remote desktop from a head-less virtual machine to another to fake somebody viewing ?
Any other smarter solutions I haven't thought about ?
You should be able to log in to Windows on the VM's console using the vSphere client, then close vSphere, and Windows will still believe the user is viewing the console. Simple as that. :)
So there shouldn't be a need to involve remote desktop in the mix.
As long as your tests then run as that logged-in Windows user, you should be fine.
This technique has always worked like a charm for me with certain Watir, Selenium, and MS UI Automation tests that depend on having an interactive desktop.
If you need to reboot the VM automatically before/during the test, instead of logging in manually in the vSphere client, you can make Windows log in as an arbitrary user automatically - check the "control userpasswords2" command, or you can use the Sysinternals app "Autologin":
http://technet.microsoft.com/en-us/sysinternals/bb963905
Only catch with this technique is that you need to be able to launch your tests while not viewing the console on the VM, but it sounds like you've already taken care of that?
If you need a solution for launching your tests remotely, I highly recommend using Jenkins or Hudson to kick off tests/collect results from the VM. Jenkins has changed my life in this regard.
You may consider using the Network Suites functionality of TestComplete:
http://smartbear.com/support/viewarticle/16849/
It can open Remote Desktop connections on its own, control tests on remote PCs, and pull the logs back to the "master" project. This feature is designed to be used for distributed tests, and looks like it's just what you need.
As for opening RDP to a head-less VM, it should not be a problem - it's up to Windows to "think" about this. You just open RDP and it works even if there is no monitor attached to the remote PC/VM.
I hope this helps,
Alex
You can always use VNC with checking the option "Do nothing" when disconnecting viewer. This way you'll trick windows to generate the image.
