Look for a remote access software which is possible to connect even when the monitor of the host machine is not connected - remote-access

My setup is as follows:
Computer 1 and Computer 2 are connecting to only 1 monitor through a HDMI Bi-Direction Switch. Just by pressing button on HDMI Bi-Direction Switch, I can switch between Computer 1 and Computer 2
I have Computer 3, which wants to remote access to Computer 1.
I want to use Computer 2, and let other (Computer 3) to access Computer 1 at the same time. But I can not because
When both Computer 1 and Computer 2 is turned on, but Computer 2 is using monitor.
Then Computer 3 can not access Computer 1 anymore (in fact, Computer 3 can access, but can not control anything of Computer 1). If I switch monitor to use Computer 1, then Computer 3 can access Computer 1 as normal.
I have tried several software such as TeamViewer, Chrome Remote Desktop, but none of them worked.
Can you suggest any software or any other method that works?
Thanks very much.

If the machine that you're trying to access is is running Linux, you could use ThinLinc for this task. ThinLinc will create a full virtual desktop session for the client and doesn't need a screen connected to the host machine.
ThinLinc is free for up to 5 simultaneously connected users.
Other option includes VNC (TigerVNC, etc), but I think that ThinLinc is way better and easier to setup than VNC, for example, ThinLinc already has sound redirection by default and can be accessed from multiple users simultaneously.

Controlling old manufacturing PC with new PC

I'm going to ask the question very generically, please bare with me.
The current setup I'm working with is Old (Linux) Computer in office controlling $millions worth of equipment in Fab. Due to firewalls/Computer being very old, we can't remote desktop to the machine - replacements and modification to current system are not an option. Many problems that come up can be solved in 10 minutes, but require a 30 min commute to the office.
Is there a way to control the input to the current system with a Modern PC? Hardwire the modern PC into the Linux system, and remote to the PC. Ideally we could remote login to the PC, and see and control the Linux system while the Linux system/Fab doesn't know anything has changed.

is there any way to debug android app on device while using remote desktop

As I and most of us WFH nowadays I am curious to know if there is way we can debug android app using remote AS and device connected to local machine.
I am using my laptop to connect my work machine which is super fast compare to my laptop so I want that device connected to my laptop is accessible by AS running in my work machine(Remote desktop).
I tried enabling usb port sharing while connecting to work system with remote desktop but no luck.
Yes in fact there is, I had the same problem as you, I was WFH but my Remote machine was unable to detect devices plugged into my laptop at home through Windows Remote Desktop (both machines Windows 10).
After searching for a long time I found the following the guide here: https://workspot.zendesk.com/hc/en-us/articles/214248563-Configuring-USB-Redirection-with-RemoteFX-in-Workspot
It requires you to Edit the Group Policy on both machines to allow USB Redirection with RemoteFX.
After following the instructions, I was able to detect the devices on my Remote Machine and all worked perfectly through Android Studio on the Remote Machine.
After rebooting both machines and connecting the RDP, make sure to enable the device to be shared on the RDP session using the bar at the top with a Printer icon, there you can tick to enable the device.

Oracle Linux, prevent Network Adapter from sleep when running in VirtualBox on macOS

I have installed Oracle Linux 7 with the current version of VirtualBox, running on mac OS Sierra with a macbook. It therefore has a battery but is plugged in at all times.
For networking I use 2 adapters, one NAT for internet and one Host-Guest for ssh etc.
For some time now I was always wondering why I would get a broken ssh pipe, trial and error showed me that the VM will go to sleep (black screen), which causes the network adapter to break, telling me the name of the adapter and simply Reset adapter as soon as I wake it up again by typing into the vm itself.
I can then restart the network adapter via /etc/init.d/network restart and it will work again
Any ideas how I can change that? My Linux skills are very limited and I am not even sure what Oracle Linux is based on, most tips I find online do not work, no GUI also makes it difficult to just hop into power settings or something similar
This worked for me, on Windows host machine.
Configure your network adapter to
1) Allow the network adapter to wake the computer,
2) Allow a magic packet to wake the computer,
3) Allow IPV6

Now, when I sleep my computer, and then wake it up, I get networking on both the host and guest, not just host.

windows xp to windows 7 file transfer via USB and via command line

I have a windows XP based computer that is connected (peer 2 peer style) to a Windows 7 based computer. The goal is file transfer between the two.
Here's hitch one, the connection between the two computers is via USB. Ethernet is not an option and completely off the table for this situation, we're stuck with USB (Windows XP computer hardware configuration is inaccessible save for the USB hub). We do have the ability to install software on it though.....same situation goes for the Windows 7 machine
Here's hitch two, The solution MUST be implemented such that file transfers can be accomplished via DOS command terminal from the Windows XP based computer...so no bridge cable and "GUI dragging of files" is allowed. A bridge cable driven by DOS command line..now that would be a solution but have yet to see one.
Here's some buzzwords I have accumulated through some lengthy google research that might help explain where I believe I'm heading.
usbnet
RNDIS
PuTTY
plink
FTP server
I would like to ask how the IT experts would handle this, what software is needed on which end and what kind of configurations could I expect to have to deal with. I am a bit unsure about the whole ethernet over USB thing as it applies to this peer 2 peer situation and would welcome any advice.

Scrambled Keyboard - VMware on Linux from NX Client on MBP

The problem:
I have a scrambled keyboard while using VMware Player on Linux from NX Client on a MacBook Pro. Letters are numbers, numbers are letters, delete is comma, e is delete; it's pure madness. I asked Google but it seems just as confused as me.
Note:
I am using an old-school mac keyboard with number pad plugged into my MBP and an additional monitor.
Things I've tried:
Altering my Linux keyboard settings (Layout: USA, USA Macintosh. Model: Apple, MBP, Apple Aluminum)
Altering my MBP keyboard settings (actually didn't see any settings that would affect this)
Unplugging my old-school keyboard with number pad and only using my MBP keyboard
Have the same issue, but with virt-manager (NX client runs on my Mac 10.6.8, connects to an Ubuntu 10.10 server and all is well, but if I run virt-manager and open a virtual machine, the keystrokes sent to the VM are all messed up).
I guess it has something to do with the Mac NX client and the VNC client (built into virt-manager) on the linux server. I tested the same setup in a Windowx XP virtual machine and it worked flawlessly. So it's got to be the Mac NX Client somehow.
As a workaround I've found that if I create an SSH with a port-forward from the remote linux-server (where I used to run virt-manager to access a VM running on another server) to the server with the VM and I forward a local port to the VM's vnc-server, then I can start up a VNC client (on the linux-server that I connect to via NX) and connect to the VM via the SSH tunnel and keys work just fine. So in my case the problem is somehow with the Mac NX Client + virt-manager's embedded VNC client.
I'm just guessing here, but VMware Player might use an embedded VNC server+client as well to show you the VM's screen. And both the reason for the problem and the workaround might be the same. Ie. try to use a separate VNC client to connect to the VM.
Update: I've got the solution to my problem, it's a KVM bug. The KVM machine starts the VNC server for the VM without specifying the correct keymap to use. See: http://blog.loftninjas.org/2010/11/17/virt-manager-keymaps-on-os-x/
The solution for VMware Player might be just as simple. A little googling revealed that VMware supports connections to a VM via VNC. Here's how to specify a keyboard layout for a VM's VNC server: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004815
Probably you just have to:
shut down the VM
open the VMX file in an editor
add the proper keyboard layout to the file as described on the page linked above (I guess you should specify the layout that your Linux server uses, eg. en-us)
start the VM and test with a VNC client
Of course it'd be better if you could tweak the Player's console to handle keycodes properly, but I did not find a fix for that.
