- MadHarvey, on 05/11/2009, -2/+26Are you stupid? The X window system has provided remote graphics capabilities since the 1980s with full multi-user capable environment.
The capability of a Linux system to provide multiple users their desktop environment remotely is so far beyond Windows it isn't even funny.
Windows has its strengths, but Linux lays the smack down in this respect sir. - tama00, on 05/11/2009, -1/+22X was originally created to be forwarded onto another computer. Back in the mainframe days the mainframe had X forwarding to all the terminals and that's how they used the GUI. Later X was created to be used on its own machine and the code still remains. So not only is this old this is ancient!
- ACiDGRiM, on 05/11/2009, -0/+17This is NOT VNC at all. IT's 100% X11 forwarding over ssh. the advantage of this over vnc is that vnc updates the entire screen every time some changes, that means even when the mouse twitches a pixel, this only updates the elements that change. When you click on a menu, all it does is download the data for JUST that menu, and dosen't have to download the data for all of the windows open over and over

The advantage this has over just plain x1 forwarding over ssh (to my knowledge) is that it forwards the ENTIRE session, instead of just the program (gedit). It also saves the session so if you loose the connection, you can connect again and it's the same as before.
I used this a lot before I made my server go head less. It works at almost full speed even over 56k - leamanc, on 05/11/2009, -1/+11Some hints to this person teaching our students:
Running Matlab on multiple computers via terminal session does not relieve you of license requirements. If so, organizations would just buy a Citrix server and one license of all the software they needed.
And it's "where," not "were." - tomz17, on 05/12/2009, -0/+10Agreed... this is NOT VNC, it is compressed X11 forwarding.
- ATL, on 06/20/2009, -2/+12No.
- Culyt, on 05/12/2009, -0/+9Then don't ***** use VNC, VNC is basically the "it works" of remote desktop access. People use it because it gets the job done and requires almost no setup (it's just built into Gnome now and will even advertise what servers exist over ZeroConf/Bonjour/Avahi so you don't even have to know the address). There is also hundreds of implementations.
NX is like VNC but is much more, including sound and is much faster, although I've never bothered with it myself.
SSH natively supports exporting GUI windows over network, as does Xorg.
The other thing is most things under Linux don't require GUI at all, its ***** stupid that under Windows in order to move a file or setup a server you basically need a full desktop. - ATL, on 06/20/2009, -1/+10You don't need PuTTY or any other SSH client. The FreeNX client logs into the NX server over SSH all on its own. No client-server forwarding or anything like that is needed. It listens on port 22.
- ElliotShoe, on 05/12/2009, -0/+8Wow, did you even read the headline. IT SAYS LINUX (you can use xrdp but WHY)
- ATL, on 06/20/2009, -0/+8Sparking a Windows/Linux debate is not wise if you really think that printing remotely is that big of a strong point.
good luck with the settings/config? its very easy! you obviously don't know what you're talking about - inactive, on 05/11/2009, -1/+8I might try this over the PuTTY config I have been using.
Anyway, its nice to Help my parents on their Linux box, 140 miles away... - evilregis, on 05/11/2009, -0/+6I have had this set up running before to log into my Ubuntu machine at home from work. It's great. Much better than VNC. It's faster and uses less bandwidth. I definitely recommend trying it out.
- ACiDGRiM, on 05/11/2009, -0/+6Hi Troll.
- DangerCollie, on 05/11/2009, -1/+7Ubuntu comes with vncviewer but in my experience it doesn't work very well. Might give this a shot and see if it works any better.
SSH, PuTTY, all fine if you don't need the graphical interface. It's kind of fun remoting in because I can kick off Amarok and make everyone in the office wonder where the music is coming from. - NinjaBoy, on 05/11/2009, -3/+9Is it VNC based? One of our interns techs installed vnc on a testing box and never told us about it. Flash forward to about a year later and there was the vulnerability in VNC and the old testing box got hacked. We caught them when they tried to access the real servers but still, a scary experience. We now us ssh -X only for Linux boxes and LogMeIN.com for the windows machines. The less things I have to worry about keeping updated the better.
/ramble - Smegzor, on 05/11/2009, -1/+6I use FreeNX, Putty and ssh -X. VNC is slow, insecure and clunky.
- ATL, on 06/20/2009, -0/+4I like FreeNX but it makes this odd session that I haven't been able to access outside of FreeNX.
If someone can explain to me how to use FreeNX to log into the console session or to log into the FreeNX session from the machine itself then I would be pretty happy.
With my MythTV box, FreeNX is great for running a separate standard "desktop" session for other things, while leaving my MythFrontend console session alone... which is easily accessible with VNC.
One thing I don't like about VNC is that anyone sitting at the machine can just watch what you are doing and essentially take over... unless you lock out the keyboard/mouse, I'm not sure if you can lock out the screen like you can with Windows. - Tenareth, on 05/12/2009, -0/+4Seriously? X predates MSWindows by a long shot and was/is much more usable than RDP. Just because Microsoft saddled their OS with a local GUI doesn't mean it was a good idea.
- waspbr, on 05/12/2009, -1/+4I think your rant is unfounded, if you go to the website of the company, you will see that as well as deb packages they have rpm and tar balls. It seems to me that someone just wrote a ubuntu howto and someone went up to digg it.
If you are a more experienced linux user you will have no problems getting around the ubuntu focus. Ubuntu is noob friendly and that is what makes it popular, like it or not.
The article is part of a blog, it does not need to be thorough, it does not need to mention all the distros and alternatives, it is just a simple howto.
I really wish people would just be glad that they have learned something new instead of bitching that other distros were not mentioned or that it did not list all possible alternatives. Just get over your diva complex and get on with your life - javaroast, on 05/12/2009, -0/+3Much faster than VNC. It's really worth giving a try.
- NTolerance, on 05/12/2009, -0/+3Pick the "shadow" option in the Nomachine client to see the console. This doesn't work with Compiz/Desktop Effects.
- bjwest, on 05/12/2009, -1/+3If all you need to do is send a PDF, why in the world would you need to worry about the speed, permissions, or internet speed of computer you're usings? You don't need a GUI, just ssh into your computer at home and email the file from the command line. You can even do this in Windows with the right 3rd party software.
- javaroast, on 05/12/2009, -0/+2Another neat freenx trick is to set up a session to run a app in a floating window. In the client select Custom and floating window in the options. Type the in the command to start the application you want to run and just like that you have the application running in a floating window. NX does have a few quirks, but it's a lot faster than VNC and secure by default.
- UTKEngineer, on 05/11/2009, -0/+2It's also "vice versa" not "vis a vis"
- UTKEngineer, on 05/11/2009, -0/+1Is this a better solution than SSH plus VNC?
- eqisow, on 05/12/2009, -0/+1I still don't get why you'd run a full desktop instead of ssh -C -X, but whatever.
- jbell1, on 05/12/2009, -0/+1is it faster then vnc? I like vnc but if I had to to pick a flaw in it, is it doesn't hold a candle stick to RDP when it comes to speed
- waspbr, on 05/12/2009, -0/+1That is why if you are going to use VNC you should tunnel it through SSH, SSH is encrypted by default, when you tunnel a VNC connection through SSH then the VNC connection becomes encrypted too.
Though I do agree that VNC on its own is not safe.
ssh -X is a good and simple alternative, but it can be rather slow, depending on what you use it for. - cawpin, on 05/11/2009, -2/+3Forward your VNC session over the SSH connection. That's what I do for my parents and my mother in law in Indiana as I'm in Arizona. It works just fine.
Putty can handle tunnels, under that label in its configuration. Command line SSH just uses the -L switch to forward a local port to a remote one.
ssh -p "Port number" -L localport : remote network ip to connect to : remote host port username@ssh-server
ssh -p 22 -L 5901:localhost:5900 cawpin@ssh-server
This will forward port 5901 on my machine through the SSH tunnel on port 22 and connect it to the remote VNC server on 5900 using "cawpin" as the SSH username. Since the SSH server is running on the same machine as the VNC session is on, localhost is the remote server. You just have to remember that the -L looks at the hostname in between the two colons AFTER it has established the SSH tunnel. If the VNC session is on a separate host than the SSH server, such as the SSH server being on a router, then you just substitute whatever that is in place of the "localhost" in my example. I use IP addresses normally since then it doesn't matter if the hostname is configured correctly on the remote network. - grg183, on 05/12/2009, -0/+1uhhh ..to be exact it has been included in the X Window System (the one used by GNU/Linux) since like 1986
- bdbr, on 05/11/2009, -2/+3I hadn't heard about FreeNX before, but I have to say this article is lame. There was never even a link to the FreeNX page (though it isn't hard to find), and its written as if Ubuntu is the only distribution on the planet (hell, there's even a FreeBSD port). It also doesn't mention why this is better or worse than alternatives like VNC & X-Windows.
- linagee, on 05/12/2009, -0/+1Until the cops break open your front door and find nobody home.
- brundlefly76, on 05/12/2009, -0/+1You don't need to argue the usefulness of ssh to me - I use it daily.
If you missed any part of the headline, story, or my comment, we are discussing >graphical< login clients.
However, in that particular case (which did happen to me) - I needed to view the PDF to check it was the right one before sending, and the email address was in my >graphical< email client, and my sysadmin does not allow incoming ssh not only without a pre-authorized incoming IP, but only via public/private keypair (oddly, my private key was not on the hotel computer, nor did it have an ssh client installed to begin with).
Also, I couldn't tell you the IP address of that computer off the top of my head to begin with. - priegog, on 05/12/2009, -0/+1In Ubuntu a remote desktop is setup by default also.
But it only works as that, a remote desktop, accessing what you see on the screen.
This is a different thing. - inactive, on 05/12/2009, -0/+1No binary available for Fedora?
- ifknot, on 05/12/2009, -2/+2yeah, and?
- RPGmaster, on 05/13/2009, -0/+0New to Linux? No.
New to me? Yes. - bigbrovar, on 05/12/2009, -0/+0Thanks guys am not a native English Speaker and i will make the necessary corrections
- thisthatwhat, on 05/12/2009, -2/+2Welcome to the world of networking and remote connections.
- torgreed, on 05/12/2009, -0/+0It's still there. Assuming you're already running X, and somehost has XDMCP running:
Xnest -query somehost :1
If you're using gdm, this should do it for somehost:
[security]
DisallowTCP=false
[xdmcp]
Enable=true
That's useful for people who want a full X desktop, but aren't on the same logical system, so there's no shared files or anything. Or are on Windows, but want to use the Gnome or KDE stuff on UNIX. - inactive, on 05/12/2009, -2/+2"the advantage of this over vnc is that vnc updates the entire screen every time some changes"
VNC has multiple polling options. Full screen is only one of them. Read the docs. - Azathothh, on 05/12/2009, -2/+1uhhh this is was included in what? Windows 95? 98? Is this new only today in Linux?
- btbluesky, on 05/12/2009, -1/+0X11 forward is slow. Yes it does only limited to the GUI components you're pointing, but it also push all the other data related to the components as well (states, data contexts...). Not to mention you HAVE TO RUN a x11 env in the client machine. A good compressed vnc session is faster hands down.
- NoDitchDigging, on 05/12/2009, -2/+0My roommate used to remote into our MP3 server using RDP from his office and blast some good metal to annoy the neighbors who were always loud.
- Bowie, on 05/12/2009, -4/+11986 called, it wants credit for its idea.
- brundlefly76, on 05/12/2009, -6/+2I really wish Linux would get some support from LogMeIn or GoToMyPC.
I have used stuff like X-Windows, VNC-du-jour, RDC, PCAnywhere, NoMachine, etc for years, but I have never found any of them as reliable, usable, fast, or feature-laden as LogMeIn/GoToMyPC.
There is nothing more frustrating than having to, say, send someone a PDF file while on vacation, running down to the hotel office center, pray the PC has the chops, permissions, and internet speed you need to find, download, install & configure your special remote client software in a reasonable period of time, and praying that you or your sysadmin has not made any special changes to your network, security, IP address/DNS since the last time you logged in which might prevent you even getting connected. - Nickedynick, on 05/11/2009, -11/+4Not really revolutionary, but a nice coupling of VNC and ssh.
- NinjaBoy, on 05/11/2009, -9/+2I will say the one nice thing about RDC is its already installed.
