need command line (terminal) from hyper-v

gbern001 · 09-21-2011, 12:46 PM

I have untangle working under hyper-v to test a simple solution but I wanted to get a terminal to run remotely and/or get the linux integration services running for hyper-v.

Both require a terminal windowed opened on the console and I can't see how to get that.

( FYI I am not a good linux user)

I can get the grub window open but dont know if I can control a cli boot from there.

I get the graphics untangle window open but I don't believe that keyboard input is captured at all at that screen to open the terminal from there.

I am able to get to the remote admin window and I am working from there.

So I need ssh on or some way to trigger the terminal windows from the bootup.

thanks for any help

At the console window, you can click on the bottom right button. That will allow you to set a root password and access the terminal.

After that you can enable ssh if you'd like or just run your commands from there.

However, if you're not "a good linux user." I'd rate your chances of getting the hyper-v linux integration services running at about 0%.

You could try this http://blog.allanglesit.com/2009/05/...tu-and-debian/

Note- I have not tried this, just googled it

The point of the original question is that I don't have mouse support from the untangle console on the host VM in hyper-v. I can't click on the terminal icon, so I can't get to the cli to do what I want to do (enable ssh for example). So I can only admin untangle from another machine but w/o ssh, I can't even try to add the hyper-v integration.

So does anyone know if there is a keyboard command to get a terminal window to open?

Or a trick from the remote admin window to enable ssh?

Nope. Worked during installation (that's how its up and running) but from the graphic console, it doesn't seem to do anything.

Are you RDPing to the Hyper-V server?

You can start Untangle in "Failsafe" and start SSH from there.

Quote:

when Grub comes up hit down arrow then up arrow (so that you have Debian GNU/Linux, kernel 2.6.26-1-untangle-686 line) followed by "e" then go the kernel line and hit "e".
Remove "vga=791 quiet Splash" and add "init=/bin/bash" and then hit "enter" followed by "B" to boot.
Debian/Untangle will now boot in to a root terminal but only with read permissions.
So we will need to remount it as rw. do that by "mount -o remount,rw /"

then you can follow the normal instructions on how to enable ssh.

I dealt with the exact same scenario.

I have a Server 2008 box running in a datacenter. I am running Untangle under Hyper-V but because it is an RDP session to the server 2008 box, I have no mouse control over the running Untangle box after installation and such a simple thing as keyboard control over the Untangle GUI would be nice, but it doesn't exist - so no way to "click" terminal and get it to open.

This is how I get around it.

First, you'll need to boot to single user mode and reset the root passwd and enable SSH.

Reboot your Untangle VM and use the TAB key at the Grub loading screen. Arrow down to the kernel line and press 'e' to edit. Add "init=/bin/bash" to the end of the line and press ENTER then B to boot. (I'm pulling this from memory, so I can't remember if I had to remove any entries off of that kernel line when I added the init parameter. You might need to remove the splash parameter too)

If all goes well it will drop you right to a root prompt pretty quickly (in a few seconds).

Issue the mount -o remount rw / command to make the file system read/write.

Use the passwd command to set your root password.

Issue the rm /etc/ssh/sshd_not_to_be_run command to enable SSH.

Issue the reboot command to restart your untangle box normally.

It will now be listening for SSH connections and you can login with root and your new password.

The second obstacle is pulling up the web interface to configure untangle. Now that you can SSH to the box, do that. At the command prompt issue the following commands:
psql -U postgres uvm
(at the uvm=# prompt) update u_access_settings set allow_outside_admin = 'true';
(at the uvm=# prompt) \q
/etc/init.d/untangle-vm restart

Now your untangle box will accept web connections on its external interface for administration purposes.

And there you go. I was able to remotely install and configure an Untangle VM using this procedure on Hyper-V.

But, my final note is this: You will not, under any circumstances, be able to run the Hyper-V integration on the untangle box. They use a kernel version that is right in between two version that you can install integrations on. Trust me, I spent days on it. There is no way to do it, and no reason to do it. Untangle runs fine without them. Just make sure you use legacy network cards. They'll show disconnected but will work fine.

appleodity/webfool.

thanks. that's exactly what i needed to know. i am going to try this tomorrow.
as for the remote admin. i was actually able to enable that from untangle - because it only became a "remote" admin once I was outside the the subnet, so i just set another vm ip to the same subnet and was able to get in.

my fear is that for any reason, the untangle cannot be reached on web portal, i will lose it forever. nice thing about hyper-v though is that I just made a copy of the vhd, so i could allows replace the vm with a backup image.

Other way to fix this, is to not RDP into the Hyper-V host, but use the RSAT (Win7 SP1 version http://www.microsoft.com/download/en...s.aspx?id=7887 ) to do this, which will require that remote admin is enabled properly on Hyper-V standalone, or as a component of server 2008, and that the logged in user on Win7 box has those rights.

YMMV I have to do this on occasion from my "home" office to the "office", and well, 3g sprint in the rain at 10 miles from the tower, to DSL isn't always speedy, but can usually get the job done.
