Ubuntu Servers :: Select OS In Multiboot Server 10.04 Without Keyboard/display?
Jul 19, 2010
Is there a way to select a second installed OS on a home server system without display and keyboard? I am putting together a home server (for mail, storage, media streaming) using an Atom-based Ubuntu Server 10.04 on a 4 GB intern flash drive and 2 hard drives for data storage, but no display or keyboard. I want to make periodic full backups of the system (flash) disk and use a second OS (installed on a partition on the hard drive) with a graphical interface (e.g. Xbuntu or PartImage) for maintenance purposes. I can connect remotely (from a Win7 or a Linux computer) to the X-display once the second system is running.
a) how can the second OS be booted on this server without keyboard? Is there a way to tell Grub2 to look at some hardware switch (or file) for the menu selection? The board has a serial and parallel port so I could wire up a switch to some pin of one of these. Also external USB connectors are available on front and back. Or can Grub2 read its default OS choise from some simple file, easily to change from a shell command of the eBox webbased system control internface?
b) I assume the second OS is needed to make a complete backup of the server OS on the flash disk. Can the backup be automated? (i.e. switch to second OS, backup, reboot first OS)
Am carrying out installation of CentOS-5.5 on a Sun fire X2270 server using PXE. The installation starts well but on getting to the keyboard type the installation halts. I have plugged in a USB keyboard unfortunately, am unable to select the keyboard type even on reboot as the keyboard is non-responsive.
I have gotten my project ubuntu server 10.04 up and running and logged in remotely with a terminal emulator program called AccuTerm that I use from work. It has multiple control files and want to know which file works best with ubuntu server. My reason for asking is some of the manual pages do not display correctly and keyboard functions seem to function incorrectly via VT100 and I have eighteen to choose from?
I'm currently trying to use preseed to build an ubuntu server box over the network. I'm using the netboot.tar.gz from the karmic main mirror. By default it installs the standard kernel (linux-2.6.31-16-generic), and I want to use the server kernel (the metapackage linux-server which should install linux-image-2.6.31-16-server). I'm using a minimal build:
Code: tasksel tasksel/first multiselect minimal As far as I can see all the other preseed settings are close to defaults. I've tried setting both of the following lines (separately and together) with no effect: Code: d-i base-installer/kernel/image string linux-server d-i base-installer/kernel/override-image string linux-server Once the machine is built, if I run:
I am trying to use an Apple BT keyboard with a new installation of 10.04.Using Bluetooth Preferences, I discovered the keyboard, and paired with it. No problem with pairing. If I click on the BT icon in the top panel, it indicates that the keyboard is connected. But any text typed on on keyboard does not appear on screen. I opened Keyboard Settings, thinking that I might have to select the connected BT keyboard as the input device. Nothing there. Is there another preference somewhere that has to be set for the BT keyboard to actually work as an input device (as opposed to simply being paired)? My USB keyboard is still connected (and is working). Perhap Ubuntu only tolerates one keyboard device at a time?
I've just installed the new 11.04 of Ubuntu. And when I restart my computer, I'm given only a few seconds to choose Windows 7 or Ubuntu, I can't choose because my WIRED keyboard is OFF!I don't get it, it's not supposed to go off when it's wired. My mouse is also wired. Do I need to install drivers for them? They're both plug and play.My system is... WIRELESS Internet - Desktop - Windows 7 Professional - 64bit - Dual core processor, 1tr drive.I really want to give the new Ubuntu a go.
Whilst trying to install Slackware -current (using the usbboot.img), I'm able to hit enter to boot the hugesmp kernel but when it comes to pressing 1 to select a non-US keyboard map, nothing happens. It's a USB keyboard incidentally.
I've done some searching around but can't find anything conclusive on this error. The tech at my remote site restarted the 9.04 server(not sure if it was accidental or planned) and when it started the boot process, an error like the following shows up...
"The display server has restarted 6 times in the past 90 seconds. This indicates that something bad is happening."
I installed server 10.10, but it has the wrong keyboard layout. Can i change it to swedish via ssh, because the keyboard preferences wont start via the vnc?
Clean install of 10.04 Server 32 bit.Only services OpenSSH Server and Print Server.Machine boots and can be accessed through ssh.Virtual terminals (cntl-alt-1,2,3,4,... do not result in video to the monitor (no sync) or a display.If I type blind, I can log in, ssh back to my other machine, and create a file. So the virtual terminal is there and listening to the keyboard and running, just not creating a display.
This machine has been working fine with 08.10 for quite time up until yesterday, so I don't believe it is a hardware problem.Any ideas why the video on the virtual terminals would not work?
trying to set up a very minimal X on my 10.04 64 bit version of Ubuntu running nothing but Open SSH and acting as a firewall/router, making a PPP connection. The reason, is that I want to set up KVM/Qemu and run a virtual machine. The virtual machine will have a graphical environment and will be connected to my TV so that I can watch movies, stream TV etc. using it. So far, I have done the following:
i need a php script to format and display a select amount of text from a file or a cron job that'll do it (with grep etc) and out put to a file but whatever is easier i want to display all the banned ip's i have in my .htaccess file i have a lot of lines in my .htaccess file but i have a line that read like this:
the 3 test ip's are 123.123.123.123 and i want the "" stripping and the "|" removing and each ip to be on it's own line like this:
123.123.123.123 123.123.123.123 123.123.123.123
i'm not bothered if this is a php script that'll read the .htaccess file and display the output or a cron job that'll run every x mins and output it to a .txt file but i'd prefer a php script
Well i see this forum and i found my answer but can't resolve my question. Anyway, I'm currently working on a solution for a network work and not sure if this is possible at all.in the fair post he doing a question about the pxe server and is my same question.How to install a multiboot server.
What i nedd is a Server that will offer multiple OS, so when the client pc turn on cant choose what OS like use Windows Linux, Ubuntu, Debian, Windows 2003 server
I was installing Ubuntu Server 10.04 last night, and the select software to install step failed. I tried to start over from scratch, but then the partitioner wouldn't load. Has anyone else seen this before?
I want to configure a remote internet facing server as git server. I would like to restrict access to the server to a few systems (access is restricted to select computers, not users). I first thought of using ssh key, but the key can be copied to another system hence that alone is not sufficient. I am having a dynamic IP, so simple IP based firewall blocking is also not possible. I was thinking about the possibility of using both SSH Key and IP based access. Is it possible to update the firewall rule whenever my ip gets changed?
I am using MonoDevelop with SQL Server whenever I try to do use the Select method on the Datatable object the performance really detoriates it is 3 times slow than it is with .Net. Are there any work arounds?
When ctrl alt d or the icon on the bottom left corner is pressed, it sometimes doesn't show the desktop and instead restores hidden windows. Is there a way to access the desktop directly, without only one shortcut ? I was also wondering how useful are these hidden windows (sometimes, the icon in the application bar is bar after being idle for a while).
i did not search in depth for this, as google spit a whole of different aswers at me, making not much sense at all. So here we go: Is it possible to install Fedora on a PC which has no keyboard nor mouse nor display attached to it? And if so plx give a link or a short description how to do it. I read about kickstart, but this was all a little wacky.
I noticed that while Compiz has every keyboard shortcut imaginable for moving windows between desktops, there's no shortcut for moving a window to a specific display when using dual monitors.
So far, I've found the best method is to use the command line automation tool: xdotool - [url]
Here's what I did:Test out the xdotool in a new terminal window using this command Code:
This should move your terminal window 100 pixels in from the top left of the leftmost display.
Find out the top-left coordinates of your rightmost display by using the Nvidia X Server Settings tool in Main menu > Administration or via the terminal:
Code:
Go to X Server Display Configuration and click the rightmost Display in the layout section. Its position offset should be displayed in the position field. Make a note of these two numbers.
Create a script to move your window, either to the leftmost screen or the rightmost screen, using this code or similar:
Code:
Remember, the number at the end is an argument that denotes the display (1 for left, 2 for right). Assign a keyboard shortcut to your custom shortcut. Repeat for the right display. Now when you press the keyboard shortcut, the active window should be moved to either the left or right display!
I setup 10.04 on an older Athlon XP 3000+ ASUS A7N8X board with a Radeon RV250 video card. It works fine and dual boots with XP on the LCD monitor I have. I took it to my mom's an connected to a iiyama Vision Master 450 CRT. When I boot, I get the grub menu, and if I pick Windows XP, it boots fine. If I pick Ubuntu, the screen goes blank, as small underline cursor appears at the top left, and then the monitor goes into sleep mode and the keyboard is no longer responsive.
I cannot seem to gain access. I cannot hit CTl-ALT-F2 (or ALT-F2) to get to text login (screen is sleeping and no keyboard control). I tried Live CD, it shows a graphic at the bottom of the screen and then goes blank as well! Seem like something with monitor resolution, but I cannot seem to figure out how to force it to work. I can't seem to figure out how to get into command line mode on boot either.
I have several machines which have been dual booting Ubuntu and Win for a couple years. Not much problem with setting them up, and Ubuntu has been trouble free. With this Maverick release, however, I've had quite a bit of trouble. Having trouble characterizing the flakiness, but it persists on this machine as follows ...
I did a clean install of the 10/10/10 distribution, dual booting with Win 7. Seemed to install OK and boot up once, although there might have been small problems during install, causing me to start over clean. Machine is relatively new AMD X4 940, with ATI HD 4800 video. The first flaky thing is that Sometimes (>50% of the time) the USB keyboard and/or mouse don't work (locked up). Sometimes one does, but not the other, sometimes neither work. I can't characterize why, but rebooting sometimes fixes it. The Win 7 environment is fine.
The second flaky thing is that after the initial boot to the graphical desktop, more often I boot to the black login screen. By reading this forum, I've found that "sudo service gdm start" usually starts the graphical desktop (although mostly with the mouse and or kbd frozen). This is a clean install, with the proprietary ATI driver added. I am dismayed, because this is so different from my earlier experience with Ubuntu. Don't know if these problems are somehow linked, or quite how to proceeds. Just looking for more stability.
When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
The Gnome keyboard layout applet, accessible by: System | Preferences | Keyboard | Layouts | Add... does not display preview of chosen layout after selecting it. What could be broken?
I'd lie to leave the display intact and updating while locking the keyboard and mouse. Ideally, a password would unlock the keyboard but hot keys would work as well. Is there already software to do this? Or a Gnome "screen saver" that doesn't effect the monitor?
I have a computer whose display I want active all the time, but that I don't want people coming up to and doing anything on. At the same time, I want the keyboard and mouse to remain connected because even though they will seldom be needed, when they are needed it's important that they be available quickly.I guess I'm looking for a screensaver that doesn't save the screen. Something that prevents the mouse and keyboard from doing anything unless a PAM authentication is entered, just like a screensaver would
1. Does Fedora 12 support ICU 4.4 Development Milestone 3 (ICU 4.3.3) with Unicode 5.2 full integration.(M3) ?
Microsoft's Uniscribe (usp10.dll) actually does not, neither in Windows XP nor in Windows 7. Will say is it possible to display complex scriptures like Devanagari, Avestan, Arabic etc. in Open Office Writer 3.1.1 via Fedora 12?
2. Is there any feature in Fedora 12 to build one's own Keyboard Layouts (like Microsoft's, Keyboard Layout Creator which isn't able to create Keyboard Layouts using Unicode Ranges bigger than U+ffff)?
I have a LAMP server. I know sql but I'm currently learning PHP.
Correct me if I'm wrong, but you're supposed to use PHP to insert/select data from the database, right? If so, SQL shouldn't need a port at all.
Apache uses port 80, but it's listening for connections. MySQL uses port 3306, but I've never logged into it from anywhere besides 127.0.0.1/localhost. I have mysqladmin installed and it demands that I give it an IP so I used localhost.
I'm not interested in doing anything remote, so can I block this port? When I say "block" I mean on the router, not locally through iptables. Obviously I have to foward port 80 because that's how people would connect to my server. But once they connect and send something, my server would interpret the data locally and send it back on port 80.
I am having trouble getting grub to automatically boot into ubuntu server. When I turn on my server the grub menu shows up and shows me the choices. They all work fine except that grub wont automatically select one. This wouldn't be too much of a problem but this is a headless server and I can't boot into ubuntu without a keyboard. I tried looking through the grub 2 documentation but nothing seemed to work when I edited the conf file.
