Now I would like to add remote + desktop capabilities so users outside could login to the system and get their desktop up from home or + another country. + </span>”</p><p>“<span class="quote"> + Is there a way to accomplish this? Do I need a Windows Terminal Server? Do I need to configure it so + it is a member of the domain or a BDC,PDC? Are there any hacks for MS Windows XP to enable remote login + even if the computer is in a domain? + </span>”</p><p> + Answer provided: Check out the new offer from NoMachine, “<span class="quote">NX</span>” software: + <ulink url="http://www.nomachine.com/">http://www.nomachine.com/</ulink>. + </p><p> + It implements an 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 that makes the thing + fast enough to run even over slow modem/ISDN connections. + </p><p> + I could test drive their (public) Red Hat machine in Italy, over a loaded + Internet connection, with enabled thumbnail previews in KDE konqueror + which popped up immediately on “<span class="quote">mouse-over</span>”. 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 + that my score was 631750 points at first try. + </p><p> + NX performs better on my local LAN than any of the other “<span class="quote">pure</span>” + 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 “<span class="quote">copy'n'paste</span>” 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 passing interest in remote computing + <ulink url="http://www.nomachine.com/testdrive.php">http://www.nomachine.com/testdrive.php</ulink>. + </p><p> + Just download the free of charge client software (available for Red Hat, + SuSE, Debian and Windows) and be up and running within five 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. 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 for last: 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 do not 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 do not 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 now use a (very inconvenient) commandline 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 class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2952700"></a>Network Logon Script Magic</h2></div></div><div></div></div><p> +There are several opportunities for creating a custom network startup configuration environment. +</p><div class="itemizedlist"><ul type="disc"><li>No Logon Script.</li><li>Simple universal Logon Script that applies to all users.</li><li>Use of a conditional Logon Script that applies per user or per group attributes.</li><li>Use of Samba's preexec and postexec functions on access to the NETLOGON share to create + a custom logon script and then execute it.</li><li>User of a tool such as KixStart.</li></ul></div><p> +The Samba source code tree includes two logon script generation/execution tools. +See <tt class="filename">examples</tt> directory <tt class="filename">genlogon</tt> and +<tt class="filename">ntlogon</tt> subdirectories. +</p><p> +The following listings are from the genlogon directory. +</p><p> +<a class="indexterm" name="id2952778"></a> +This is the <tt class="filename">genlogon.pl</tt> file: + +</p><pre class="programlisting"> + #!/usr/bin/perl + # + # genlogon.pl + # + # Perl script to generate user logon scripts on the fly, when users + # connect from a Windows client.
