Ubuntu :: How To Run Desktop Of Another Host
Jul 24, 2011
The short form of my question: Can I log into a remote host from a local host (on the same LAN) and get the full GUI desktop environment of the remote host?
Long form of question: I worked for years on Solaris hosts with the CDE environment. Our server hosts were in another physical location. My desktop machine was another Sun Solaris host which also ran CDE. At the CDE login screen, I could click a dropdown menu and tell it to login to one of the server hosts at the remote location. In my login script on the remote machine, I had "export DISPLAY=localhostname:0.0", where localhostname was the hostname of my desktop host. There was also some kind of security command that had to be in the login script to allow the windows to be sent to another host, but unfortunately, I cannot remember what that command is.
What I want to do is configure another host on my LAN, but without a mouse, keyboard, and display monitor. I would like to run the GUI desktop of the new host on my current main host, just like I did at work. Is this possible in Ubuntu with Gnome?

I am planning to make my own server as a web host on the Internet not at the local area with the desktop 10.10 desktop edition with the domain name you know like the hosting providers hostgator or bluehost.

I'm trying to setup my Ubuntu 9.10 laptop to host a small website that I can practice and learn stuff with and I'm a little stuck at the minute.
I have got Apache2 and the LAMP stack installed okay, along with phpMyAdmin and can give my external IP to anyone with the http:// and anyone can view my website that way but what I want to do is have my IP resolve into a domain name like ooloo-website.net but I don't know how to do this.
Is there any way that I can do this like register my IP to a free DNS and domain website without buying a domain or using one of those free ones like ooloo.webhost.net or do I need to host everything myself like DNS and the domain? Can I even do all of this myself?

I have deny host installed and working on my laptop, running Lucid. On attempting to install it on my desktop, also running Lucid I get the following message when trying to start the service
graham@graham-desktop:~$ sudo service denyhosts start
[sudo] password for graham:
starting DenyHosts: /usr/bin/denyhosts.py --daemon --config=/usr/share/denyhosts/denyhosts.cfg
sh: /usr/bin/denyhosts.py: not found
Its very strange as on the laptop denyhosts.py is not used.

I have access to a unmanaged dedicated server on the net. I am considering loading Ubuntu Server to this for web/mail/ftp serving. If I install Ubuntu Desktop to my local machine is it possible for me to administer the server using Ubuntu Desktop (using the GUI)? I connect to the net over ADSL. Any guides/advice for setting up Ubuntu as a web/mail/ftp with a key focus on keeping to secure? I know how to install LAMP but as I have root I need to learn a little more than I did when I was on a shared host.

I have succeeded in using Remote Desktop Viewer to make a VNC connection to a remote WAN computer and it was quick enough to manipulate the remote computer in real time.I found the host name by getting the remote target computer to put the following url into a browser - http://www.showmyip.com/ - It returned the address for the router which I put into the Host: text entry box in the Remote Desktop Viewer window. E.g. for my computer at the time of submitting my enquiry the address was 'host81-129-54-226.range81-129.btcentralplus.com'.The remote router that I connected to needed to have the port 5900 forwarded to the remote target computer.I now want to progress to running VNC through a SSH tunnel for additional security. In the Remote Desktop Viewer there is a configuration line
'use host' <text box to enter host name> 'as a SSH tunnel'.What is the correct syntax to enter in the text box? It would help my understanding if you used the example address above as a basis for a response.Many unexpected connection attempts reported on my router, if that was you, thank you for the novel way in responding to the question and providing the syntax.The 'bible' on syntax appears to be found here:- http://unixhelp.ed.ac.uk/CGI/man-cgi?ssh+1

Are there programs for this? Really really simple page layouts that you can edit and host from a graphical desktop that has your web browsers and Pidgen and VLC media player and everything running on it at the same time?

I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.

I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.

Bit of an odd one, this. I've migrated a website from my old server to a new machine. Both servers run Ubuntu + Apache2. Both only serve a single site, apart from the default site.I've flipped the domain name to the new IP address.The trouble is that after moving the virtual host config over into sites-available, with the necessary link in sites-enabled, Apache attempts to serve from the default web root (/var/www) rather than the actual site content (in /var/www/technology). So for example, an attempt to browse.

I'm trying to get Synergy up and running between my Windows 7 (server) host and my Arch Linux (client) host. In rare exception, synergy works perfect on my windows host, however every time I try and run Synergy on my linux machine I get the following error in messages.log:
[code]...
I'm running Arch with a barebones Xorg install and SLiM with LXDE. I'm not sure what in the world is causing the problem and haven't been able to find anything of substance in a search.

So here's the setup:
Ubuntu 10.04 host inbound port 22 open
FreeBSD 8.0 host no inbound ports open
Both hosts are running sshd currently. What would you do for the Ubuntu host to be able to ssh to the FreeBSD host? A tunnel?

I am a bit of a n00b when it come to linux but I am setting up a test environment were I have a appliance monitoring network traffic. Part of my test requires me to copy a file via RCP from one host to another host. I have two ubuntu boxes. I have allowed the subnet in the etchost.allow for ALL. I have installed rsh-server
When I try to copy the file it looks like it tried to use SCP instad of RCP because it connects to 22 instead of 544. Also note that traffic must be unecrypted thus me trying to use Is there anyway to make ubuntu go old school to allow me to use rcp instead?
Code:
testuser1@ubuntu:~$ rcp /home/testuser1/test.txt testuser1@10.46.41.38:/home/testuser1
ssh: connect to host 10.46.41.38 port 22: Connection refused
lost connection
testuser1@ubuntu:~$ rcp
usage: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[Code]....

The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc.
- connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays)
- traffic shaping is not running
- there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago.
- changed the internal NIC with another
- connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R.
- R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R).
- the problem persist only between R and machines from the internal network.

I have installed CentOS 5.4 machine named test.example.com (192.168.1.1)File /etc/hosts contains:127.0.0.1 test.example.com test localhost.localdomain localhostI have read that the loopback addres should not be assigned to host name,only to localhost and the host name should be assigned to 192.168.1.1, like this:127.0.0.1 localhost.localdomain localhost192.168.1.1 test.example.com testIs there any reason why it should be one or another way?

I'm working on getting my myth box hooked up to my Sony flat panel display.Originally the nvidia drivers could not read the EID, so defaulted to only 640x480 over my HDMI-DVI connection.I manually updated xorg.conf with a mode for the resolution I know the thing can handle. Suddenly there are several resolutions avaialble in nvidia-settings and it seems to be communicating with the TV, as it is now listed as a Sony FP display rather than a CRT.I'm able to change the resolution now as expected.my problem, however, lies with the TV itself. I can't seem to get it to actually display the output. I'm able to remote desktop into the box and can see Gnome logged in and everything.However nothing on the TV itself.How do I troubleshoot this? Am I missing something obvious?

I want to make a live-USB containing among others both Ubuntu desktop i386 and Ubuntu desktop AMD64. How do I go about this? I tried using unetbootin, first adding i386 and then amd64, but that failed. My computer with an athlon II did manage to boot, and showed it had booted into the 64-bit version (ram shown was 3.9 GB, i386 goes to about 2.7 I think), my wife's computer with a pentium 4 did not manage to boot, got to a black screen. I think this is because casper has issues, being overwritten (I'd seen something to that effect somewhere), and thus only the latest version added being booted (in this case amd 64).
I'm under the impression that the startup disc creator included won't help, nor won't the multicd.sh script, so how do I circumvent the issues?

1. Is it possible to instead of using the Desktop Folder plasmoid, have a usual Desktop act as a file manager?
2. What is Akondi? There are tons of processes which have Akonadi in their name, and it seems to be using up lots of memory.Can I disable these somehow, or is it safe to do so?
3. Any general tips on how to reduce the amount ram that is used on startup? I am using somewhere around 750MB on startup, which is about double the amount Gnome uses. After a few hours of use, Xorg uses close to 1GB of memory.
4. Whenever I get a notification, they don't delete themselves, so when I click on the (i), I see tons of notifications. Is there a way to get them to delete themselves after they have been shown?

I have my main box, Ubuntu 10.04lts, and I am trying to use remote desktop viewer to see the desktop on a Windows XP machine. The machines are side by side The Ubuntu box is hardwired to my network router, and the XP machine is connected via wireless. Both get to the internet fine, and I can ping the Ubuntu box from the XP box. But, I cannot ping the XP box from the Ubuntu box, and Remote Desktop Viewer won't establish a connection to the VNC server I have running on the XP box.
