I was wondering what the best way to secure RD would be? What's the best one to use? I'd prefer a method that isn't always active, so maybe something that I need to enable via ssh first?
View 4 RepliesFor a Secure Remote Desktop on Ubuntu 9.10 here is how I did it using OpenSSH, FreeNX and a router with DD-WRT v24. Pic of it in use at bottom of post, transferring a file and remote desktop at the same time.
For the purposes of this guide I will use a Desktop as the Server (Host) which is at home. The Client will be a Laptop that I can use to control the Desktop remotely. First you should already be familiar with the Terminal which is where you enter commands (anything in a "Code:" box).
In Ubuntu it is in Applications > Accessories > Terminal In Kubuntu it is usually on the lower left taskbar and is called Konsole I am using Ubuntu so you may have to make some adjustments to this guide if you are not using Ubuntu. Installing OpenSSH (for the rest of this guide I will refer to it as only SSH)

I need to securely control my home computer from work. My home computer is connected to the internet via a wireless router using Tomato. I'm using the latest Ubuntu on both ends. Is the Remote Desktop that's installed by default good enough? What settings do I need for my home router to safely allow my remote connections and not leave it open to intruders?

But both of them need some approach to provide security. I'd like if someone could give me some pieces of advice on choosing the simplest and better approach:
To secure kfrb or x11-vnc is simpler or better to mount a vpn or to use an ssh tunnel? Is there any other solution? My pearents ISP use DHCP, so I think it would require some service like dyndns or similar...

I'm trying to secure the CentOS servers on our company network as the current situation is, shall we say, less-than-ideal: remote root logins with the same password across several servers (behind a firewall, on non-standard ports, but still) and several key processes running as root. My proposal to amend this consists of the following:
- setup a bare as possible SSH-gateway with only the normal user accounts to handle remote access
- disable the root login from anywhere else but LOCAL and create special accounts with root permissions for our ~4 system administrators, like admin.foo admin.bar that can only login from inside the company network, using SSH-keys.
So far my biggest obstacle seems to be creating the administrative users, how do I go about and do that? When I simply create a user adminfoo with uid=0 it will show on my shell as root, which makes it useless as a way to make our admins accountable for their actions. BTW, my initial proposal to use sudo unfortunately met with strong resistance, because it compromises usability.
I maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?
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?

View 1 Replies View RelatedI am trying to setup my HTPC. I wanted to have the most minimal overhead possible so I installed Ubuntu 10.10 server from the mini.iso and just added the ssh option. I then used the following command to give me a desktop environment because I will want to run firefox and it apparently requires this to run.
Here is the command that I ran:apt-get install xorg gnome-core gdm gnome-applets gnome-system-tools gnome-utils ubuntu-artwork compiz-gnome firefox sysv-rc-conf.The desktop works fine and I can open fire fox, however, the remote desktop is missing from the preferences menu.How can I install this?

I have set up a server running ubuntu desktop, and I'm able to logon through remote desktop (win 7). The problem is that if I logon from computer 1 and open some programs, I don't see these programs when I logon from computer 2.I logon with the same user, so I find this strange. Is there some setting I have missed to be able to see the same from any computer (logon through remote desktop).

View 4 Replies View RelatedI've been using Linux on a more regular basis for the last two months now and have been able to find replacements for most of the software i use in Windows, or by using Wine. But i have one big problem that is keeping me from switching permanently to Linux. I frequently use remote control software to access and control my computers, both at home and to access my computers from remote places over the internet. I've been using NetOp, and more recently RealVNC. The client, or "viewer" part of RealVNC is working fine in both Windows and Linux. It's the host or server part that i can't get to work properly when it comes to VNC. The vnc.so module doesn't work on my system, x0vncserver program seems rather useless since it refuses to load before i have a network connection and this prevents me from start the program automatically as the wireless connection isn't ready and the vncserver command isn't an option since it doesn't display what i see on the actual screen. So, does anyone have a nice solution to this problem? Either to make VNC work or suggest some software that does. Anyway, it has to work on both Windows and Linux, in Linux it has to display the native x display, there must be built-in encryption and preferably be free or open-source software. I'm using Ubuntu 9.10.
View 5 Replies View RelatedI'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.
I installed a fresh copy of Ubuntu 11.04 on my server about 2 weeks ago, I setup remote desktop and figured to just leave the password field out as it suppose to be pre-configured to only accept local connections, well, apparently not. I was noticing some strange network activity and checked my router connections and sure enough I see port 5900 to the server, open vino icon and see that there is someone else connected! (IP of unauthorized user: 77.29.51.239 ).. Immediately kick them and set a password. This should really be addressed and/or a password should be defaulted or at the very least the "Your desktop is only reachable over the local network." should be removed.

View 2 Replies View RelatedI've run into a bit of a problem with an attempt to remotely admin a friend's computer. Here's the basic layout:
--My Ubuntu is connected via wireless router, port 22 forwarded properly. I can ssh in and out as I please to other hosts.
--Across the internet, their Eeebuntu is behind a router as well. Port 22 may or may not be properly forwarded. Nobody in that house really knows how to access their router. (I accept this may be an issue I'll need to handle)
What I'd like to do:First priority, ssh access to the remote Eeebuntu.Assuming the remote router does not forward port 22, would I be able to have the remote computer remote forward, say my local port 10022 to remote 10022, thus allowing me to ssh user@localhost:10022 and bypass the need to access the router?
Lower priority, prepare a bash script for my friend to download that would require one input of the root password, and go through the full process of installing OpenSSH, setting up the server, and initiating contact to my computer. The ideal situation is allowing my friend to start the computer, run one script, type in one password, and walk away.Any ideas for better remote admin options are welcome, as well as comments/suggestions from anyone who has attempted this backwards form of ssh access.
I am using Ubuntu 9.10. I can do remote desktop into the system with a monitor attached but when I reboot the system without a monitor attached I am unable to do remote desktop into it.
I want to use this system as a headless system and only use remote desktop to control it.
So I guess I need to start X and gnome without a monitor attached.
What do I need to do to get this to run?
is remote desktop from windows to ubuntu possible?
so far i googling, only found from ubuntu to windows.
i installed 10.04. when i try to dial into my work pc using my work VPN which uses Sonicwall using SSL-VPN technology. It works fine using older versions of Ubuntu, other linux versions, and XP or Vista. Using 10.04, I can login just fine, but when I get into the remote desktop, my keyboard does not work. the mouse works fine. I am using the newest version of java (1.6-20) with Ubuntu 10.04. I don't think I am using this version of java in the other linux versions, so I'm not sure if this is a problem with java, Ubuntu, or something else. i got the kb to work by pressing cntl-J, typing stty sane, then ctrl-J again, which is something I remembered from a long time ago..

I wanna start using now remote desktop , so i can connect to my home server through vnc.
I've tried this old post here , but I could not connect
What I did was to ssh with putty (and Xming) and X11 forwarding on , to start vino-preferences , which seemed to work BUT even though I connect with vnc to my remote server , all I see is grey stripes....
PS I have forwarded port 5500,5800 and 5900 to my home server pc of course
remote desktop requires authentication on server side when trying to login remotely via VNC. I have the option set to not require confirmation of each access to the machine, I set a password that the user must enter from the client side.just testing this locally over my LAN, VNC connects and asks for a password(the user field is blank; might be nice to have to enter a valid username and password so I don't have to share a general password). after entering the password on the client, a window pops up on the server 'An application wants access to the keyring Default but it is locked' and requires me to enter a password, which once I do then the VNC gets control and all is good... but obviously if I am trying to remote further than down the hall this won't work.
Ideally I would like to remote into ubuntu desktop with account credentials from the server and require no physical person at the server to allow access. I currently have an XP pro box setup this way with remote desktop and works flawlessly. I want to keep it true to the same functionality where when I log in remotely it joins a session with applications already running, such as a web browser and mail client, with those applications left running when I logout of the remote session. its not all that important if it locks the server side locally as there will eventually be no physical access to the machine once its been setup.
as you may have noticed I am fairly new to linux, but very willing to learn. my primary reason to move to the linux platform is that I am hoping it will provide better performance than windows XP/windows 7 when I upgrade the box to an atom based mainboard. any other thoughts or recommendations on my planned setup would be greatly appreciated as well.just to be clear, the 'server' is ubuntu desktop and client side is generally windows XP, windows 7, windows server (I work almost exclusively on windows boxes)
How/where can I configure remote desktop so that other PC can access my lubuntu, since lubuntu doesn't has "System -> Preferences -> Remote Desktop".
View 6 Replies View RelatedSet up my mom with Ubuntu and want to be able to connect to her computer remotely to help her out when she has a question. I did some search and it seems that everyone recommends using openSSH. I used this link [url]
To install it on my mom's computer (changed the port to 16 instead of 22 and added those lines he suggested to the end of that file). Now what? I can't seem to find any instruction to connect the two computers. Looking around I also found:
1- Remote Desktop Viewer
2- Terminal Server Client
under applications/internet and
3- Remote Desktop under preferences
It looks like I can use those to connect also. But are they related to openSSH? Should I uninstall openSSH and use 1,2 or 3? Which is moe secure or are they the same.
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?
