  • Ubuntu Server 12.04, NAT, Router, DNS. It just doesnt work

    - by Bjørnar Kibsgaard
    I recently inherited some server hardware from work and decided that it could be my main router at home (among other things). Ubuntu 12.04 server installation harware wise goes well and everything is found and working when I boot up. So I begin with setting up eth1 with DHCP. This works fine and it gets a public IP address from my modem and we have a working internet connection. Then I set up my other NIC (eth0) as static (192.168.0.1) and this also works fine. I can access it from other computers in the network. The problems are coming when I am trying to set up a DHCP server with isc-dhcp-server. It seems like it is working and giving the computers IP adresses but after one reboot it stops working. After the reboot eth1 will get a public ip from the modem but it doesnt have internet access. I have to manually run dhcpcd eth1 to get it to work again. As far as I know I havent made any changes to DNS. What am I doing wrong? I have never really had problems with this before. :)

  • HP DV6 connects but no internet

    I have a Hewlett Packard DV6. I connected to the access point. I receive an IP address/default gateway/DNS,etc(DHCP). I cannot ping my gateway. DNS lookups fails. There is just no connectivity.

  • Can you still install Ubuntu 10.10 with Wubi?

    - by I Heart Ubuntu
    I am trying to help a friend get set up with Ubuntu and want to recommend Wubi for his install (he is not very computer savvy). I had recently tried the Wubi download from Ubuntu.com and the only option it gave me was to install Natty. Is there any way I can get Wubi to install 10.10 Maverick? Preferably just the EXE file, not having to download an entire disc image as the friend has no idea how to burn discs. Thanks much!

  • How do I remap the keyboard shortcut for Gnome Do?

    - by johnc
    I am giving Unity a chance to win me over in Natty, but I admit I am a heavy Gnome Do user and Unity has remapped the Super+Space keyboard shortcut to show the Unity Launcher. I am not yet convinced with the new Unity Launcher and would like to keep using Gnome Do, at least until such time as I am convinced that the Unity launcher is as frictionless as Gnome Do. Is it possible to remap it to Gnome Do?

  • How do I fix this half screen problem?

    - by link1275
    I just installed 12.04, and my entire screen is being displayed entirely on the top half of my screen. The bottom half is always black or some technical garbage from the boot up. To interact with the bottom half of the screen I have to move the mouse over the screen to pull part of the bottom half of the screen on top and vice-versa. Does anyone know how to fix this? Also my computer told me, at startup, to go to here: http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware.

  • How do I run update-grub from a LiveCD?

    - by Kelley
    Okay, so I did something stupid. I was trying to clean up my Grub entries, and accidentally removed all of my Linux kernels from Grub (they're still on the hard drive). So now, obviously, Grub doesn't give me any way to boot into Ubuntu; I can boot into Windows just fine, but Ubuntu isn't even listed. So I just want to run "sudo upgrade-grub" somehow to restore Ubuntu to the list. I can boot from a LiveCD, but once there how do I run that command? (My Ubuntu installation is on sda5, by the way.)

  • Remote Desktop between Ubuntu Machines

    - by user19192
    My desktop and my laptop are connected to the same router. I want to be able to remote login from my laptop to my desktop. Laptop is 12.04 and desktop is 12.10. I tried putting xrdp on my desktop, but remmina wouldn't work with it. I also tried the default screen-sharing, but it was very slow. Also tried rdesktop but it was very slow. I am on 12.10, FreeNX looks like a good option but they don't have a 12.10 release. And when I tried to install the 12.04 release, I got errors about dependencies missing. How can I get local-feeling remote login speeds?

  • How to get past black screen with mouse icon while installing on Gateway MX6920?

    - by tom kruse
    I have an old Gateway MX6920 laptop that got a virus on its hard drive so I put in a new one from another laptop. When i turn it on it tries to load Windows but fails so I'm going to try to put Ubuntu on it (because I heard it's a good OS). I downloaded the 32-bit desktop version of Ubuntu and burned it to a CD. I put the CD in the computer, went to the boot menu, and selected CD-ROM. The computer tries to boot but stops at a black screen with a mouse icon sitting in the middle of the display. I have no idea what's going on, so please help.

  • Multitouch screen not detected on Asus Taichi 21DH71

    - by geekfreak
    I just bought this Ultrabook "Asus Taichi 21 DH71". This has Intel 3rd generation i7 processor and 4gb ram with 256 gb SSD. The main feature is that it is a hybrid machine. Naming it has dual screens. When the lid is closed it can be used as a tablet and when lid open it can be used as a notebook. This machine can also be used with the two screens on at the same time. I used ubuntu many years ago and loved it. But I never tried any linux later. My questions are Does the new version of Ubuntu support the Multitouch interface? Will it work specifically on this machine? Will Ubuntu support gestures on multi touchpad? Update 2/22/2013 I did try the latest 64bit Ubuntu(12.10) from live usb and noticed that it couldn't detect the tablet screen. Everything else worked seamlessly. Do you guys think the tablet screen would be detected if I make a complete installation on to the notebook? Please help guys..

  • Quicker alternative to gnome-screenshot? (no animation!, quick!, no frills)

    - by humanityANDpeace
    I want to take screenshots in Ubuntu. This is normally no big problem with the standard gnome-screenshot program is working good. But just now I ran into trouble because I need to take a screenshot of some window which appears only for about 0.5 seconds. The Problem is that the gnome-screenshot is using a (from me at least disappreciated animation when used... this fancy thing kind of delays all and I really cannot manage to take the picture..) So what I need is a "no frills" "down to the ground" alternative to the gnome-screenshot. I really disklike the animation - now because it makes me so much trouble. I also hate it that there appears to be no way to disable it after all. Everybody is forced to accept this animation that looks like "a flash light is going on". I am not against being fancy... but this animation in gnome-screenshot is impacting/reducing its functionality. Indeed in my case the shortly appearing window hides when loosing focus. The animaiton -as I assume- triggers the "loosing of focus". So because of the animation I cannot take the screenshot. Anyhow I have looked for "less frills" alternatives and I have found that shutter is a programme that commes with quite some baggage.. But maybe somebody knows a very light-weight programm that serves the very sinple (do nothing else) purpose of just taking a screenshot...

  • Is this fix for Avast Antivirus crashing safe to use?

    - by TmRn
    Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: Press Ctrl+Alt+T to open the Terminal. When it opens, run the command below. sudo gedit /etc/init.d/rcS Type your password and hit Enter. When the text file opens, add the line: sysctl -w kernel.shmmax=128000000 Make sure the line you added is before: exec /etc/init.d/rc S This is what it should look like: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S Save the file. Reboot. My question is: Did I do anything wrong? I mean as I have made some tweaks, will it lower the security of Avast down like viruses do? Please if you are a programmer check this if it contains bug or harmful intentions... Thanks.

  • Xubuntu: Screen idle-dims after lock+new login although not idling

    - by unhammer
    I set my screen to dim after 2 minutes idling on battery in XFCE power settings. If I lock and click new login, and log in as another user, the screen will dim after 2 minutes even though that second user is active. Is there some setting or workaround for this? It feels like a bug, but I have no idea what program or combination of programs would be responsible … (I don't know if this affects Unity users or not.)

  • Using todolist (abstract spoon) on ubuntu 11.10?

    - by Tal Galili
    I wish to run todolist 6.3.8 (http://www.codeproject.com/KB/applications/todolist2.aspx) on ubuntu 11.10. I have installed the latest wine and winetricks. I have tried running: http://www.codeproject.com/KB/applications/todolist2.aspx winetricks vcrun2005 winetricks vcrun2008 winetricks vcrun6 Which installed all of the components. When I went to run todolist.exe, it started fine with the "first time wizard" (asking me where to save definitions and what file to open first), and then it stopped saying "the program todolist.exe has encountered a serious problem and needs to close. we are sorry for the inconvenience". What can I do to make this (great) software work on ubuntu? Thanks.

  • Lexmark X7170 shows documents as printed when they haven't

    - by Mehmet
    I made the move from Windows 7 to Ubuntu not dual booting because I have decided to quit gaming to spare more time for my studies. I just needed an OS for browsing the web and word processing etc. After I installed Ubuntu I installed the AMD GPU drivers, after which I clicked on the little printer icon, selected add printer and it found the drivers for the Lexmark 7000 series and I installed them. Now my problem is when I print something from Writer it processes it thinks its completed it, when in fact it hasn't printed anything. I tried printing a test page but it was stuck on processing for 5 minutes. I have restarted my computer and turned the printer on and off. I'm running 64bit if that changes anything.

  • High temperature on my laptop with Radeon Mobility HD4670

    - by Lorthirk
    As almost everyone here, I guess, in these days I downloaded Quantal Quetzal to give it a try. However I noticed that my laptop runs fairly hot with cooling fans almost always on, even sitting in the desktop doing nothing. I downloaded XSensor to read temperature sensors, and I saw that while CPU stays on about 65°C, so quiet normal I guess, the GPU sits at 75°C. In comparison my actual Windows 7 installation, which dual boots witb Quantal, stays at 59°C CPU and 65°C. So I went reading and learned that AMD dropped support for my video card from fglrx package, and that fglrx-legacy won't support 1.13 Xorg, so I'm basically stuck with OSS drivers. So I was guessing if there's anything I can try, and if it's possible that the OSS drivers could be the cause of the high temperature?

  • Cannot establish ssh connection to computer on local network

    - by ovangle
    I've just (re)installed ubuntu 11.10 on my main pc, and the connection times out every time I try to ssh connect to my laptop (over the local network) to retrieve the files I backed up there. The connection times out every time I try to connect. I can establish a connection in the other direction without issue. Here's the verbose output I get when I try to connect: ovangle@ruby-EP43-DS3:~$ ssh -v [email protected] OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.1.1.4 [10.1.1.4] port 22. debug1: connect to address 10.1.1.4 port 22: Connection timed out ssh: connect to host 10.1.1.4 port 22: Connection timed out ssh is installed on both machines, and I've tried deleting '~/.ssh/known_hosts' on both machines, still nada. I've changed the sshd logging on the laptop to VERBOSE and restarted the daemon (because I wasn't getting any relevant syslog entries otherwise), and this is the log for the most recent connection attempt. EDIT: posted wrong logs last time. They just showed that there was a connection received, they weren't actually the sshd logs (which were in auth.log as I recently discovered). Unfortunately, that log is filling up with extremely weird error messages and it gives me no information about the connection.

  • Aide On a Low Memory System

    - by Jason Mock
    I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

  • How to grant standard users access to disk partitions and flash storage?

    - by JK04
    I have a partition that I need standard users (not administrators)to have read/write access to. However, this partition does not even appear to them as it does to me as an administrator. How can I make it so that standard users can read/write to this partition? It would be nice if they could have the ability to mount it if needed. I have the same problem with removable media - if I have a flash card in the computer, the standard users cannot see this storage media.

  • How to fix slow wireless with Intel 4965 AGN? [closed]

    Possible Duplicate: Slow wireless with an Intel 4965 We run Ubuntu 12.04, 32bit, with the current kernel 3.2.27-generic on an MSI EX700. I've already added the 11n_disable=1 tweek, without whcih, wireless has been unusable. Now, it works OK, but speedtest shows: Windows XP - down 11.68mbps, up 2.07mbps Ubuntu 12.04 - down 2.06mbps up 2.0mbps We've disabled ipv6, tried static and dinamic IPs, tried both swcrypto=0 and swcrypto=1 options, none of whcih made any difference.

  • Cannot boot from Ubuntu USB

    - by Safi
    I create a ubuntu 10.10 bootable USB via the method that is described on the download page of ubuntu. I made that from windows and also from ubuntu 10.04 (I have dual boot). When I boot from the USB made, the menu shows and when I run it, it gives a beep and nothing else. It never boots. USB creation from both methods result the same. I downloaded ubuntu via the torrent provided from Ubuntu. Any help will be very appreciated. I want to make my USB just like a Live CD so that I can run it on some other computers also.

  • Graphical Mode breaks after suspend/ returning from Console

    When I try to go to a virtual console (ctrl alt f1) and return to f7, my screen freaks out. Its black with frequent white 'lightning bolts' flashing across the screen. Nothing works, but to force shutdown. Same when trying to resume from suspend. This doesnt happen every time, but very often. I dont know what information might be useful but: Ubuntu 12.10 ATI RS880M [Mobility Radeon HD 4200 Series] Gallium 0.4 on AMD RS880 this line in xsession-errors might be pertinent: (gnome-settings-daemon:1825): color-plugin-WARNING **: Done switch to new account, reload devices p.s.

  • Desktop background will not load after performing aticonfig --adapter=all --ovt=opengl

    - by user1571959
    I am trying to get Eagle to work on ubuntu 14.04 LTS. When I run Eagle and open a schematic the display is not refreshing/redrawing correctly. One solution that I found was to install the flgrx drivers and do the aticonfig command to use opengl... So I did and rebooted. Now when I turn on my laptop I get all the way to the login screen, login, and then nothing happens, it just goes to the background image with no icons or anything... I tried deleting and copying the original xorg.conf file and no results... What do I do other than reinstalling Ubuntu? is there anyway to force the original driver?

  • Eliminating zero-length files

    - by RhZ
    I have been having multiple crashes recently. 4-5 last night within a few hours. I posted about it before, and got an answer but not sure how to proceed. The messages in my logs right before the crash are multiple complaints about valid eCryptfs headers. But the chron might not be related, I don't think I saw that in previous crashes: xxx-desktop kernel: [ 1112.274474] Valid eCryptfs headers not found in file header region or xattr region, inode 32376924 xxx-desktop CRON[4212]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) So I was sent to an answer providing this script: for i in find $(mount | grep " on $HOME type ecryptfs" | awk '{print $1}') -size 0c; do if ! fuser -v $i; then rm -f $i fi done I did find some zero byte files, not in the exactly right place (a folder called .private as I remember), but I need to fix this, its too bad right now. So I need to delete any of them that are not in use. I am a little too clueless, can someone walk me through executing this script? I don't know how.
