-&gt; I have a wonderful linux/samba server running as PDC for a network.
-&gt; Now I would like to add remote desktop capabilities so that
-&gt; users outside could login to the system and get their desktop up from
-&gt; home or another country..
-&gt;
-&gt; Is there a way to accomplish this? Do I need a windows terminal server?
-&gt; Do I need to configure it so that it is a member of the domain or a
-&gt; BDC,PDC? Are there any hacks for MS Windows XP to enable remote login
-&gt; even if the computer is in a domain?
-&gt;
-&gt; Any ideas/experience would be appreciated :)
-</pre><ns78:p>

- Answer provided: Check out the new offer from NoMachine, &quot;NX&quot; software:
- <a href="http://www.nomachine.com/" target="_top">http://www.nomachine.com/</a>.
- </p><p>
- It implements a very easy-to-use interface to the remote X protocol as
- well as incorporating VNC/RFB and rdesktop/RDP into it, but at a speed
- performance much better than anything you may have ever seen...
- </p><p>
- Remote X is not new at all -- but what they did achieve successfully is
- a new way of compression and caching technologies which makes the thing
- fast enough to run even over slow modem/ISDN connections.
- </p><p>
- I could test drive their (public) RedHat machine in Italy, over a loaded
- internet connection, with enabled thumbnail previews in KDE konqueror
- which popped up immediately on &quot;mouse-over&quot;. From inside that (remote X)
- session I started a rdesktop session on another, a Windows XP machine.
- To test the performance, I played Pinball. I am proud to announce here
- that my score was 631750 points at first try...
- </p><p>
- NX performs better on my local LAN than any of the other &quot;pure&quot;
- connection methods I am using from time to time: TightVNC, rdesktop or
- remote X. It is even faster than a direct crosslink connection between
- two nodes.
- </p><p>
- I even got sound playing from the remote X app to my local boxes, and
- had a working &quot;copy'n'paste&quot; from an NX window (running a KDE session
- in Italy) to my Mozilla mailing agent... These guys are certainly doing
- something right!
- </p><p>
- I recommend to test drive NX to anybody with a only a remote interest
- in remote computing
- <a href="http://www.nomachine.com/testdrive.php" target="_top">http://www.nomachine.com/testdrive.php</a>.
- </p><p>
- Just download the free of charge client software (available for RedHat,
- SuSE, Debian and Windows) and be up and running within 5 minutes (they
- need to send you your account data, though, because you are assigned
- a real Unix account on their testdrive.nomachine.com box...
- </p><p>
- They plan to get to the point were you can have NX application servers
- running as a cluster of nodes, and users simply start an NX session locally,
- and can select applications to run transparently (apps may even run on
- another NX node, but pretend to be on the same as used for initial login,
- because it displays in the same window.... well, you also can run it
- fullscreen, and after a short time you forget that it is a remote session
- at all).
- </p><p>
- Now the best thing at the end: all the core compression and caching
- technologies are released under the GPL and available as source code
- to anybody who wants to build on it! These technologies are working,
- albeit started from the command line only (and very inconvenient to
- use in order to get a fully running remote X session up and running....)
- </p><p>
- To answer your questions:
- </p><div class="itemizedlist"><ul type="disc"><li><p>
- You don't need to install a terminal server; XP has RDP support built in.
- </p></li><li><p>
- NX is much cheaper than Citrix -- and comparable in performance, probably faster
- </p></li><li><p>
- You don't need to hack XP -- it just works
- </p></li><li><p>
- You log into the XP box from remote transparently (and I think there is no
- need to change anything to get a connection, even if authentication is against a domain)
- </p></li><li><p>
- The NX core technologies are all Open Source and released under the GPL --
- you can today use a (very inconvenient) commandline to use it at no cost,
- but you can buy a comfortable (proprietary) NX GUI frontend for money
- </p></li><li><p>
- NoMachine are encouraging and offering help to OSS/Free Software implementations
- for such a frontend too, even if it means competition to them (they have written
- to this effect even to the LTSP, KDE and GNOME developer mailing lists)
- </p></li></ul></div></div></div><div xmlns:ns79="" class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2981560"></a>Network Logon Script Magic</h2></div></div><div></div></div><p>
