Ubuntu :: Remote Connection Disabled On Restart?
Apr 30, 2010
I had this issue in 9.04, resolved it in 9.10 (it went away on its own), but it's back in 10.04..I currently run my Ubuntu machine as a headless server and connect to it using TightVNC from a Windows computer.However, this connection won't work unless I start the Ubuntu machine with a monitor connected. Once that's done, the remote connection works fine until the Ubuntu machine has to be restarted. Thankfully Linux doesn't need restarting as much as Windows does, but unfortunately, every time I restart (i.e. with a kernel update, which happened at least a half-dozen times with 9.10), I have to plug the monitor in or TightVNC won't be able to connect.
System - Control Centre - Remote Desktop is set to allow remote connections as it should, I haven't altered this on upgrade.It's like it's some sort of graphics issue - if no monitor is detected on startup, disable the GUI completely...the system runs fine in remote terminal mode over putty, it's serving files fine and running the few server apps I have on it, but nothing over TightVNC.

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've recently installed a second monitor and it's great having all that extra space.
However, Ubuntu 'loses' the new monitor after a restart and I have to go into System>Preferences>Display and get the second monitor re-enabled and put to the left of my existing monitor. Quick flicker and the second monitor is on.
I don't really want to have to do this every day so am I missing something so my second monitor is remembered?

I'm setting up an Ubuntu server and I keep getting strange problems with my editor.I'm not sure if this is because my keyboard configuration is wrong or I screwed up the installation but regardless it's quite frustrating.
When using the movement keys (arrows and numpad) I get "[" brackets and "C"s, if I hold down or push down on the key hard a list of errors and text comes up, usually involving something that says something like:"Mount disabled" or "____ disabled press CONTROL-X to restart the shell"Similair problems are also found in vi (when in insert mode).I have been plagued with text editor problems and have need several reboots just to get out of a file, often because it just flat out stopped responding to keyboard commands.

I have a fresh install of Ubuntu 10.10 on a home server. I can connect to it using vinagre from another computer just fine. However, if I restart the server I can no longer vnc to it because I need to log in (start a gnome session). Is there a way to do this using just vinagre? Do I need to install another vnc server on my home server? The problem is that I don't want to carry a monitor from another room just so I can log in and start a gdm session if the home server gets restarted.

I've tried to configure :
- a wired network
- a wireless network
- a mobile broadband network as both "system connection" and "automatic connection".
I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.

I did a bit of searching, but I guess I'm not sure of the terminology associated with what I'm trying to do.
I'm currently connected via ethernet port (NOT wireless) to my DSL modem.
Every so often my connection gets 'saturated', typically after or during a lot of bittorrent activity that maxes out my bandwith, and my speeds drop markedly, even if the bandwith isn't currently being maxed out. I'm not sure whether it's my ISP throttling my connection or something else, but as a work around, I typically just disconnect my modem from the outlet and then replug to restore normal speeds.
Is there a way to 'restart' my modem from the command line in a similar way without having to physically turn off my modem to get the desired effect?

Following upgrading my 09.04 partition to 09.10 then 10.04, all was working fine until I tried hibernate out for the first time - big mistake! If I can get to a position where i can log on to the system, I find that my ethernet network connection is disabled and I cannot get it to restart. My 09.10 system still works ok. I am tempted to do a clean install of 10.04, even though I'll have to spend some time reloading the extra's and re-configuring.

My ISP pushes software updates occasionally to my router. This also forces the router to restart. When the router restarts, my ubuntu box loses its network connection and does not automatically restore it after the router comes back online.How can I configure ubuntu to restore the connection once it is available again? It happens on my windows workstation...I am using ubuntu on a box with no screen / keyboard / mouse it serves as a fileserver and I remote desktop in. Obviously if the box drops the connection it is a major annoyance. I am using version 9.10

Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.

I'm currently running Fedora 13, after I updated the kernel to 2.6.34, I have to run (as a superuser) "service NetworkManager start" in order to start my network manager, is there are way I can run this on startup?
Also my ethernet connection seems to only work when I restart/boot up my computer, when I wake my computer up from being asleep, the ethernet stops working.

I have a Windows XP Professional desktop that I would like to remote connect to from my Ubuntu 9.10 laptop. I would like to connect in such a way that the current user of the XP machine doesn't get logged off when I connect. I have googled this subject and have been unable to find this exact subject. I am fairly comfortable using the terminal although I am still learning it. I have heard FreeNX is a good program but from what I can tell it's only used to connect from Windows to Ubuntu. Is this correct? I would also like to remote connect from the above mentioned laptop to the XP machine while at work over the internet if that's possible.

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?

When ever i run ssh -p <port> <user>@<remote IP>, i get a connection has timed out error. (i use the -p <port> part because i'm using a custom port). does anyone know what could be causing this? i know of a few *possible* problems, but i don't know how to test them all.
- I am on the same network as the server (I'm trying to test using remote IP to make sure it works before i go out an try it somewhere else)
-The router could be blocking it (i'm using linksys)
-IPtables may not be set up right (i think it is though. the only thing i've run is "sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT". I have changed the port for the server since then. maybe i have to restart it or something for it to recognise the change? I know very little about IPtables though).
-maybe i have to change something in my client or server config files? (the only config file i've changed is the sshd_config file on the seerver, and that was to change the port to my custom port).
thats all i can think of for now. It may be none of those. I do have the sshd_config and port forwarding in my router set to the same port, so thats good.

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.
