puttyvirtualization
I've created a VM running on my PC and am trying to connect the two via Putty. I have Putty installed on my PC, and openssh server and client installed on my VM. When I drop my IP address into the Putty client, a window will open up, but it's completely blank. I can highlight the blank window, but can't type anything. After a few minutes the window will close from a connection time out.
Is this my firewall??
A less error-prone way of converting public key formats than manually removing the headers and line-breaks is using ssh-keygen like this:
ssh-keygen -i -f publickeywithheaders.pub
It should output what can be appended to the authorized_keys file.
Michigan Tech has a very succinct explanation of how to use Xming here:
Installing/Configuring PuTTy and Xming
Excerpt:
The PC interacts with the server through the X-windows system, forwarding the display from the server to the PC. Software must be installed on the PC to make this link work and the best software (so far) for this task is the PuTTy terminal emulator and the Xming X-window client.
PuTTy can be downloaded from https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
Xming can be downloaded from http://sourceforge.net/project/downloading.php?group_id=156984&filename=Xming-6-9-0-31-setup.exe
Once Xming is installed, run the application called 'XLaunch' and verify that the settings are:
1) Display Settings: Multiple Windows
2) Session Type: Start no client
3) Additional Parameters: Check Clipboard box
Then in your PuTTY session you can turn on the X11: Enable X11 Forwarding
So then save that, and every time that session is invoked you will get a GUI connection to Ubuntu, as long as Xming is running.
Xming is verified by the visible icon in the lower right of the screen like so:
In the Xlaunch settings it is selected to not run on startup, so when you don't see that icon then click on Start, type xming and press enter and it will start the x-server and show the icon.
Now, when you make the connection, then you can see
pi@PRIME5:~$ echo $TERM
xterm
The leafpad editor, gnome-system-monitor, etc., work over the link via the Xming server on Windows.
It is easy to pull up nautilus and browse to
/usr/share/applications
to get any of the installed system commands, as shown here:
Voila, X11 via SSH from Windows to Ubuntu.

If you are using Virtualbox, by default it will emulate the network using NAT. This is the simplest way to provide network access to the virtual network adapter inside the virtual machine, but it has the side effect that you can't actually connect to the services on the virtual machine from the host system.
You would need to change the mode of network emulation in the virtual machine from NAT to "bridged".
Note that this is slightly more complex from your host operating system's point of view as it has to get low level access to your host's network adapter at the packet level. This involves installing a special driver, particularly on Windows hosts. Essentially your network adapter on the host will need to start behaving in a way like multiple network adapters. This can sometimes (but not in normal situations) conflict with your outer network.
Instead of "bridged", you could also use "host-only networking" which avoids all the above potential issues but then your guest OS won't have access to the wider network (eg the Internet).
If you're using something other than Virtualbox, the issues will probably be the same, but the way of fixing it may not be.
