Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

we have set up a Ubuntu workstation with accounts for all the group members. Nxserver from nomachine seems to be what we need, but it is restricted to 2 users. FreeNx isn't easily installable and doesn't seem very reliable. VNC seems to be usable for login to existing open session but not for remote logins on a single workstation.

To be clear, we need a solution to login on a workstation, desktop maintenance isn't necessary at all.

Cheers, Fred

TeamViewer should work I think,they have recently released a linux client.

Hello, this is closed source and illegal for entreprises :( . I have to look if it is usable as remote login, but if I remember rightly it is rather for remote desktop maintenance –  fretchen Oct 3 '10 at 14:51

In the old days you started xdm on the machine, and it provided remote X logins to X servers started with "-broadcast" or "-remote" (if I recall correctly).

I believe I have seen that Ubuntu can enable this X display manager, so I would recommend you have a look at if it is still possible.

Thank you, I will try to look on this. The problem is that I am looking for something easily maintenable (for the other team members) –  fretchen Oct 3 '10 at 14:50
    
Please describe what your team can and cannot and their technical skills. –  Thorbjørn Ravn Andersen Oct 6 '10 at 11:26

My way of remotely logging in my Ubuntu machine is using NX server. The client runs on multiple platforms and is free, while the server component is free for home/small use. There is also the FreeNX package which works similarly, but I did not use it yet, so I cannot say. My other way to connect is to use the good old terminal in an SSH connection. Actually, NX requires the OpenSSH components to be installed first.

Hi, this is what we are doing at the moment. But there is this limit of 2 sessions and this makes NxServer by NoMachine more or less a nogo. FreeNx isn't really installable under Ubuntu (for me). –  fretchen Oct 5 '10 at 12:51

Cendio Thinlinc can be used with 10 concurrent users in production systems for free http://www.cendio.com/products/thinlinc/. I haven't administered it, but I like the client.

remmina Install remmina

Remmina is a remote desktop client written in GTK+, aiming to be useful for system administrators and travellers, who need to work with lots of remote computers in front of either large monitors or tiny netbooks. Remmina supports multiple network protocols in an integrated and consistant user interface. Currently RDP, VNC, NX, XDMCP and SSH are supported.

Remmina is released in separated source packages:

 "remmina", the main GTK+ application
 "remmina-plugins", a set of plugins
 "remmina-gnome", the GNOME desktop applet
 "remmina-xfce", the Xfce panel plugin

Remmina is free and open-source software, released under GNU GPL license.

You can try NeatNx. It's a NX Server developed by Google for internal use. You can install it using the FreeNX PPA and afterwards installing neatnx-server.

I haven't used it, but I do use FreeNX in production and it works great. I agree that installation and configuration is a pain. We were NoMachine customers a couple of years ago (their offers were way more affordable then) and they are a really nice company (well at least they were), support from them is great and while their products don't work better or worse than others, they are way easier to install and configure than FreeNx.

I use a combination of ssh tunnels to secure X11 traffic when an X11 session is all I need. VNC clients can be used to access the mac as if you are sitting at the local display, but that one password is common for anyone who logs in, so that is less useful in a multi-user scenario.

ThinLinc might be the solution for you, it is a partially closed source, easy to install linux terminal server solution with clients for several platforms, which includes 10 free concurrent users.
