Connect to Linux guest via RDP 2

[withanh]

I have searched for and not found any articles on how to set up a Linux (Debian Lenny) guest so I can use RDP to connect.

I know, I know, why would I want to use RDP to connect when I could use VNC or anything else? I've got a Wyse WinTerm 3125 that only knows RDP and the Citrix ICA.

When searching I found plenty of ways for a Linux host to use RDP to connect to a Windows guest, but I want to go the other way around.

I would also be open to using the Citrix ICA to connect to my Linux box if that also works.

Thanks!

You could always start vnc on port 3389. That'll fool the router.

 

[withanh]

Sure, but will VNC answer an RDP request?

 

[itsp1965]

That won't help since he doesn't have VNC client capability on the terminal. If I am not mistaken you have a web browser built in to the Winterm. You can always install Webmin on your Linux box and then manage it using the browser on the Winterm terminal

 

[withanh]

You are correct about the terminal. It's not about managing the server, but Webmin would be a great option for that.

It's actually a kitchen computer at my house and I want to build a desktop as a VM on my ESXi vSphere host. Then connect to that desktop "in the cloud". That way I don't have to have a noisy PC in my kitchen, just this small and quiet WinTerm tucked away.

 

[itsp1965]

since the Winterm also supports telnet, have you tried that?

 

[mrregan]

You might want to look at this:

http://www.nomachine.com/products.php

You should be able to use the free addition to connect
from a web browser.

 

[Grenage]

I use nomachine, and it's probably the best remote access app out there.

[mrregan]

I cant believe I entered "addition" instead of "edition".
I wasnt awake yet.
Sorry

 

[engjohn]

If you are going to have a windows VM on the ESX Host, you will use RDP to the WINDOWS VM and not the Linux server... Or am I mis-understanding something?

 

[withanh]

@itsp1965 telnet only gives CLI, I want/need GUI.

@engjohn, I am running a Linux VM that I am trying to connect to from my Winterm. Winterm supports RDP or ICA for connections.

Have a look at xrdp.

- xrdp: An open source remote desktop protocol(rdp) server.

http://xrdp.sourceforge.net/

- xrdp

http://en.wikipedia.org/wiki/Xrdp

xrdp is an open source remote desktop protocol (RDP) server based on the work of rdesktop. The goal of the project is to create a fully functional Linux terminal server, capable of accepting connections from rdesktop and Microsoft's own Terminal Server and Remote Desktop Connection clients.

[withanh]

Yeah, that looks like the ticket. I'll see if I can get it running. It says they got it working under Debian/Lenny which is what I use, so I'm thinking this should be right for me.

Thanks!

 

[withanh]

Well, I think that the xrdp is what I want, but when I start the install, it errors out. I think I'm missing a component, but I am really not sure what is missing.

If someone could look through this and let me know if something is obvious to them that isn't to me. Thanks!

It seems like it's missing something from openssl, but when I

apt-get install openssl

it tells me

Reading package lists... Done
Building dependency tree       
Reading state information... Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

which tells me that openssl is installed properly.

[Annihilannic]

You probably need the openssl-devel package which would include the headers that allow you to compile SSL programmes; openssl on its own would only contain the library for use with precompiled programmes.

Annihilannic.

 

[withanh]

Excellent, I'll install that and see what happens.

Much appreciated!

h

 

[withanh]

Turns out the package is called libssl-dev, not openssl-dev. But that still doesn't help. Ugh!

 

[Annihilannic]

It's called openssl-devel on Red Hat-like systems, which is all I have access to right now; does libssl-dev include the file /usr/include/openssl/rc4.h for example?

If you can't locate a suitable package, perhaps downloading the OpenSSL source and pulling out the required header files would be a viable workaround, but it could be a little fiddly.

Annihilannic.

 

[withanh]

Yes, it does, complete list at
