Ubuntu :: Setup A Remote Desktop Connection Between Two Computers Over The Internet (UFW)
Apr 13, 2010
I would like to set up a remote desktop connection between two computers over the Internet. I already tested remote desktop within a local network but it's far from secure enough this time. I will try to follow this guide [URL] (ssh portforward and internet). This still leaves ufw and how it should be configured. Let's say I have this setup, server computer has ip 12.341.245.124 and the client has 78.12.543.234 how should ufw be configured to be secure? This remote desktop wont be connected to a local network

Alright so i just wanted to try and get remote desktop connections running so i can access files on the other computers in my house. For my first try i went after my laptop. I'm using rdesktop.
First couple times i tried i typed in
Code:
After about 15 seconds it would pop back with
Code:
I realized that my laptop's firewall was blocking the packets, so i created a custom rule that allows all TCP packets on port 3389. So i fired up rdesktop again. Now it pops back with:
Code:
But instantaneously, not after 15 seconds (not sure if thats significant or not.) I checked my firewall's log and it allowed the tcp packets.

I have internet on my ubuntu machine (eth0) I am sharing with (eth1) My windows computers are getting IP addresses via DHCP from the Ubuntu Machine, and I can see (and use) samba/windows shares on all computers. Internet connection is not working on any of the windows computers.
I have eth1 set to "shared to other computers" under the IPv4 settings

Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
Code:
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2)
It's details are;
ip 192.168.xxx.103
netmask255.255.255.0
gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)

install ubuntu 10.04 desktop, configure remote desktop so I can connect from my Mac or Windows machine without being physically be at the ubuntu machine, and I won't have a dedicated monitor for the ubuntu box either. And I want to have root access to everything via remote desktop or VNC.What I have tried: system->preferences->remote desktop to enable remote desktop, I can connect and see the desktop, the mouse clicks would only show on the directly connected monitor, not in my VNC session.Then I tried to install TightVNC server, start a at display :1, I can also connect, but every time any action requires a root access, such as installing a package using Ubuntu Software Center, the root password prompt would only show up on the directly connected monitor.
I also install xrdp package, and followed instructions here: [URL]It actually worked using Remote Desktop application from my Mac or Windows box for a little while until I restarted the machine, thinking I can unplug the monitor and connect via remote desktop from then on. Then it stopped working.

I am Trying to set up my desktop in order to access it from a remote computer using Remote desktop. I have ubuntu 10.10 and am using the included software remote desktop. When I run the programm is says i can only connect locally using the name "local host". I am trying to connect to my desktop from a vnc app on my ipod touch. It asks me for the ip address and the port.

Fresh installation of Fedora 14 x86-64 on Lenovo T510. I'm trying to setup graphical remote connection to this laptop via VNC. I installed vnc-server package and altered /etc/sysconfig/vncservers accordingly:
Code:
VNCSERVERS="2:awajda"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
I found Remote Desktop which opens vino-preferences and ticked the check boxes there. I started vnc-server and then I tried to connect to it from the same local host using vncviewer. I got no errors and the window with correct resolution came up. The problem is - that window is black and empty. I tried looking into Fedora docs but I haven't found anything useful there. I tried google and I found about 487693746874363 solutions and different ways of installing and configuring VNC server. I tried a few - none helped.
I wonder if there is a decent and consistent documentation about how to make remote desktop working in Fedora without having a real pain in the ass trying out those gazillion tweaks and tricks from various forums and blogs? After all Fedora 14 comes with that Remove Desktop thing available out of the box. Is it a real working thing or just a marketing Should I uninstall all the preinstalled VNC stuff and follow one of those painful instructions found on the internet from A to Z praying for it to eventually start working after all the magic is done and hours or days are wasted?

I am attempting to set up a VNC with ssh tunneling for remote desktop between my laptop (opensuse 11.2) and my desktop (kubuntu karmic) and using the instructions here: [URL] and here: [URL] but I am having trouble getting remote desktop to work once I establish the ssh tunnel
I start out with
Code:
ssh <user@remotepc> -p <non22port> -L 5900:localhost:5900
That seems to wok and connect properly
The problem comes when I try to use a remote desktop client on the laptop to initiate the VPN desktop sharing and point it to
Code:
localhost:5900
Thats when I get a notification on the host saying:
Code:
Refused uninvited connection attempt from 127.0.0.1
And on the laptop I get:
Code:
VNC server closed connection
I have tried messing with the few settings in Krfb, but none seem to have any impact. How do I open localhost:5900 and allow VPN tunneling to the host machine?

I want to be able to use my desktop from work over VNC but it won't let me connect. In the Remote Desktop Preferences I have "Allow other users to view your desktop" checked and I also have "Allow other users to control your desktop" checked. But it says below that "Your desktop is only reachable over the local network. Others can access your computer using the address 192.168.1.10 or brownserver.local."
Under the Security section I have "Require user to enter this password" checked and I've filled in a password for it.
I've also port forwarded port 5900 to my desktop on my router so that shouldn't be an issue either. When I attempt to connect over the internet from my laptop I get a message that says that the connection was refused. So I think my request is at least making it to the desktop, it's just that the desktop doesn't want to allow it.
One quick question though....I'm not sure, but I might have changed the default port on which VNC is listening on this machine. I don't remember if I did or not. And if I did, I don't remember how I did it. Could someone point me in the proper direction to see which port remote desktop is listening on?

I am a Linux newbie. I am trying to see if it is possible to access a windows pc through some form of vpn/rdp setup. My machine is dual boot with Windows XP. On Windows XP, I am able to connect to my office via VPN client to connect to my office, then Remote Desktop to my local machine on the network.. Is there some way for me to do this with Linux? I find it really annoying to have to boot to Windows just to access my work pc.

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

I am playing around with the idea of being able to use a cloud or instance based service to install Ubuntu 9.10 Server. This will enable me to have remote access via SSH command line.So far, I've installed Ubuntu 9.10 Server + Ubuntu Desktop to a virtual machine. I can access this via SSH and locally via the desktop. However, in the real environment the only access I am going to have initially is via SSH.
I would like to be able to connect using Windows Remote Desktop or VNC (whichever is easier and most importantly - most secure) to the machine.. even though the desktop is on there, I need to somehow configure the remote access all from the command line.I've had a read of various forums and have been trawling support forums for days but can't find a working solution for 9.10 Server or that fits my situation above where I will not have any physical access to the desktop or machine to configure remote desktop. It all has to be done via SSH/command line.

Does anyone know what could be causing a Remote Desktop connection to a 10.04 box to be closing after some period of time? I have three systems all running 10.04 with Remote Desktop enabled. I'm using UltraVNC on Windows 7 to connect to them. If I open a connection and leave it open for a long time (like overnight, for example), when I come back in the morning, I still see the VNC window but as soon as I click on it, it closes. I can immediately open a new connection to the box but it now shows two active connections. At first I was thinking maybe there's an idle timeout value but given that Ubuntu still seems to think that the original connection is active, maybe the problem isn't on the Ubuntu side but on the UltraVNC side?

If you do a search on the web you can find where to download Microsoft's Remote Desktop Connection 7 client (rdp client). To get it to work under Wine (I used Crossover Office) actually was pretty simple. You will need to copy four files from an existing Windows 7 system. Two of them, mstc.exe and mstscax.dll are located in the C:WINDOWSsystem32 directory. The other two files, mstsc.exe.mui and mstscax.dll.mui, are located in a subdirectory within C:WINDOWSsystem32.
The name of the subdirectory will depend on the language and locale of the Windows system you are using. If your language is English and you are in the USA, they will be located in C:WINDOWSsystem32en-us. Copy those 4 files to some temporary directory on your Linux system. Next create a new Wine Windows XP "bottle". Use either Crossover or Wine to browse to the SAME wine C: drive subdirectories as on the Win7 PC (see above) and copy the respective files into each subdirectory in your Wine Bottle. Two files each into 2 different directories.
Next using either Crossover or Wine execute the RDC 7 application.
wine mstsc.exe
In Crossover you can just click the button the RUN a COMMAND and just enter "mstsc.exe". The RDC login screen should appear prompting for a Server address and a login ID. You can also change various other "options". I have not tested alot but it does seem to work pretty well so far.

I was working on my desktop under Ubuntu 9.10 when I got a message in the the upper right telling me that my Remote Desktop Connection had been activated. I don't know who it was, but they proceeded to open up a terminal and start typing a bunch of stuff. This scared the living @#$^ out of me, so I didn't really pay attention to what he was doing and immediately dove for the reset button. I disconnected my network from the web and found that RDC was NOT password protected.
Now, I probably did this a little while ago while I was playing around with it, but I also set up an account with dyndns.org. Would this possibly increase the number of attacks on my network? Just in case, I have removed my listing. Also, would any of this incident be logged somewhere? How/Where would I look to see if I'm being poked and prodded for another security hole?

Today I noticed my Desktop was being controlled remotely from over the Internet even though I had it set for 'local network only'. Foolishly I relied on this setting and hadn't specified a password or other security. The remote user had opened my Firefox passwords page and was perusing this when I pulled the plug.
All external checks confirmed that my router/firewall is actively blocking correctly. How could this happen? How can I prevent this in the future? I had recently install the Firefox extension for Weave Sync and wonder if that had anything to do with it?

I'd like to set up remote desktop which I can access from any computer with a VNC client, without knowing the IP address in advance and without having access to the "server" at the time of access. I'm aware of the security risks, but there's nothing critical on the server computer, and I'll make sure I use a good password, so I'd still like to go ahead. Is this possible?

I am trying to connect to my Company network through VPN. I use a Lynksys router which is most likely not the problem, as I can get the VPN and Remote Desktop to work from a WinXP Pro laptop connected to the same router. I have tried several RDC clients, none of them establish a connection. The VPN connection is active, I can ping and Traceroute to it , but I cannot get the RDC to work. The RDC should connect to 189.0.0.10 on the company network.
