• Network Access: I can't access 192.168.1.101 from 192.168.1.102.

  - by takpar

  Hi, I'm running Ubuntu 10.04 on my PC with IP 192.168.1.101. every thing work fine, e.g. my web server is running and I can see http://localhost/ or http://192.168.1.101 properly. But the problem is that I cannot see my PC from my laptop at 192.168.1.102 e.g. at my laptop http://192.168.1.101 gives Connection timed out in browser. or trying to telnet on any port leads to: telnet: Unable to connect to remote host: Connection timed out laptop is running a fresh install of Ubuntu as well and there is no setup for firewall stuff in both computers. PS: Both computers can ping each other well. The router is a cicso linksys wireless ADSL modem. Currently, I can connect to FTP server on the Windows running on 192.168.1.102 from 192.168.1.101 without problem.

• Lamp Uninstall and Xampp

  - by southpointingchariot

  I installed lamp with this tutorial a while back: http://www.unixmen.com/install-lamp-with-1-command-in-ubuntu-1010-maverick-meerkat/ I have since decided it would be better to use the more full-featured Xampp. I installed Xampp successfully, but localhost still displays the default apache page. Apparently, I need to uninstall the lamp components individually to use Xampp. Any advice on how best to do this?

• High load (and high temp) with idle processes

  - by Nanne

  I've got a semi-old laptop (toshiba satellite a110-228), that's appointed 'laptop for the kids' by my sister. I've installed ubuntu netbook (10.10) on it because of the lack-of memory and it seems to work fine, accept from some heat-issues. These where never a problem under windows. It looks like I've got something similar to this problem: Load is generally 1 or higher, sometimes its stuck at 0.80, but its way to high. Top/htop only show a couple of percentage CPU use (which isn't too shocking, as i'm not doing anything). At this point all the software is stock, and i'd like to keep it that way because its supposed to be the easy-to-maintain kids computer. Now I'd like to find out: What could be the cause of the high load? Could it be as this thread implies, some driver, are there other options to check? How could I see what is really keeping the system hot and bothered? How to check what runs, etc etc? I'd like to pinpoint the culprint. further steps to take for debugging? The big bad internet leads me to believe that it might be the graphics drivers. The laptop has an Intel 945M chipset, but that doesn't seem to be one of the problem childs in this manner (I read a lot abotu ATI drivers that need special isntall). I'd not only welcome hints to directly solve this (duh) but also help in starting to debug what is going on. I am really hesitant in installing an older kernel, as I want it to be stock, and easy upgradeable (because I don't live near it, it should run without me ;) ) As an afterthought: to keep the whole thing cooler, can I 'amp up' the fancontrol? Its only going "airplane" mode when the computer is 95 Celcius, which is a tad late for my taste. Top: powertop:

• Computer SOMETIMES recognizes when headphones are plugged in.

  - by rcrobot

  Whenever I plug my headphones into my computer's front headphone jack, I get a weird situation. Sometimes, the computer will recognize the headphones and work properly. But other times, the computer will play sound through both the headphones and my monitor's speaker. When this happens, the sound section of the system settings does not list the headphones. I can fix the issue temporarily by wiggling the headphone port, but if it gets wiggled the wrong way again, then the issue returns. My PC's case is a Rosewill Challenger. I have tried multiple headphones and the same issue is there. I suspect that this might be a hardware related issue, but if there is any way to fix it with software, that would be helpful. This is what it looks like when everything is working properly: This happens when I wiggle the headphone port. I can quickly switch between these two by doing so:

If in /etc/network/interfaces I add auto xenbr0 iface xenbr0 inet dhcp And then later do brctl addif xenbr0 wlan0 I get this error message. can't add wlan0 to bridge xenbr0: Operation not supported I found out that Linux won't let you bridge a wireless interface in managed mode at all unless you enable the 4addr option (needed to recompile iw): iw dev wlan0 set 4addr on Afterwards brctl addif xenbr0 wlan0 works, and brctl show shows xenbr0 as bridged to wlan0. Unfortunately, as soon as I execute iw dev wlan0 set 4addr on my entire network connection is gone (no connection). As soon as then I execute iw dev wlan0 set 4addr off I reconnect and it works again. If I re-execute 4addr on, it breaks again, if I execute 4addr off, it works again. Unfortunately, I can't just turn 4addr on, activate the bridge and then turn it back off (error: device not ready). Does anybody know why I loose my connection ?

• What can I do to give some more love and disk space to my database on Ubuntu?

  - by Yaron Naveh

  I'm new to linux. I've deployed a db to ubuntu server on amazon and found out I'm low on disk space. did df (see below) - and found out that I'm 89% capacity on one file system, but less on others. What does this mean? Do I have a few partitions and can now utilize others besides /dev/xvda1? Also /dev/xvdb seems large, is it safe to put the db in it and only use it? If so do I need to mount it or do something special? $> df -lah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 6.7G 914M 89% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 3.7G 8.0K 3.7G 1% /dev devpts 0 0 0 - /dev/pts tmpfs 1.5G 164K 1.5G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.7G 0 3.7G 0% /run/shm /dev/xvdb 414G 199M 393G 1% /mnt

• Remove Grub Loader from Mac

  - by ben

  I installed Ubuntu (Precise) on my Macbook Pro but now I'd like to go back to OSX but I can't boot off the OSX Snow Leopard DVD to do a reinstall. I have tried booting and holding down "c" or using "Option" and then selecting the OSX install media but after selecting the OSX media the grub menu loads and tried to boot Ubuntu instead of booting off the DVD. I tried booting off my Ubuntu LiveUSB and removing all of the partitions using gparted but the problem still persists. Any ideas? I just want to wipe everything and go back to OSX only. When I installed Ubuntu I pretty much followed the default options. Thanks.

• Ubuntu 11.04 and 10.04 hang with black screen while installing from USB disk

  - by Bill

  I've been trying to install Ubuntu 11.04 from a USB flash stick and each time I try to boot from the USB key one of two things happen: A) The screen that asks you what you would like to do (e.g. run Ubuntu from the USB key or install it) shows up and the countdown to the default option starts to count down but as soon as I either touch the keyboard (sometimes I press enter or the arrow keys to select an option) or the countdown gets to zero the screen just locks up and nothing happens no matter how long I wait. B) When I boot from the USB key the screen will flicker for a second and then go black with a flashing white underscore at the top left corner of the screen. Again it doesn't matter how long I wait, nothing happens and pressing keys doesn't do a thing. The very first time I tried to install it I got a terminal-like screen that said something about a directory called 'casper' having an error of some sort. I have tried installing from USB using both 11.04 and 10.10. I'm about to try 10.04. I have read tons of forum posts about this but so far I haven't seen anything in the solutions that apply to me. My intention is to dual boot Windows 7 and Ubuntu. I must keep Windows as I am required to use Visual Studio for one of my college courses. Right now I'm using Wubi but I really want a full install. I can't use LVPM because it doesn't work with the version of Wubi I used. So now I'm thinking my best bet is to try to get a clean install working. I'd also convert Wubi to a full install too but there's no solution as far as I've read. So could someone tell me a reason why this is happening or if there's something I can do to get around the problem? I'm using a Gateway LT2802u netbook with and Intel Atom N455 processor, 1GB RAM, Intel Graphics Media Accelerator 3150 graphics card, and a 250GB HDD. I don't have anything on my current Wubi install that I can't replace so keep in mind when answering that I don't care if I lose my current settings and files from Wubi. Thanks everyone! UPDATE I just answered my own question so in case anyone else is having this same problem using similar hardware, do the following: When I first tried installing 11.04 I used the recommended universal installer tool to create the USB live/installation disk. That caused the original problem. Note that I had already downloaded the 11.04 ISO and did not use the included downloader from the USB creator. After that failed I used the same USB creator but had it download 10.10 for me. It also failed with the same issue. I repeated this process with unetbootin as well for both versions. Finally, I downloaded the Ubuntu 10.04 ISO and used the recommended USB creator once again. There was an error while creating the USB live install so I reformatted the USB key as FAT32 and tried again. It created the USB key. I then booted from the USB flash drive and selected "Install Ubuntu" (exact wording was different). It worked! It took me through the process that you see shown in pictures on the Ubuntu website. I let it create the appropriate partitions for me and it simply worked. I did get a few errors while the system tried to restart after it installed. It hung on a terminal-like screen but I pressed ENTER and it restarted. I booted into Windows 7, it checked the disks as it sensed that I messed with a partition, then it booted into Windows normally. Now I'm going to uninstall Wubi and update my new full install of Ubuntu! I'm excited to get the benefits of a full install now. So in the end, hopefully someone can learn from what I did.

• Unsatisfied Link Error and missing .so files when starting Eclipse

  - by Keidax

  I upgraded to the 12.04 beta yesterday. Now, when I try to start Eclipse, I get the splash screen and then this error message: An error has occurred.

• Partial upgrade error

  - by Dan

  this is an issue I have googled a lot and I have tried a lot of fixes, but non of them really worked. At some point (I can't remember when/how) my Update system sort of broke, and since then it is always complaining about "Not all updates can be installed, run a Partial Upgrade". If I click on Partial Upgrade, I get the following result But running apt-get install -f does not fix anything, and at the end I always get the following message Funny thing is that my apt-get system works perfect on Console. I can update my system through apt-get update, apt-get upgrade etc.. So.. how can I fix the graphic interface? I understand that my apt-get system is not broken, but somehow its GUI it is. Any thoughts about it? THANKS! P.D: I have already tried sudo dpkg --configure -a and sudo apt-get autoremove

• Could not calculate upgrade from Maverick Meerkat to Natty Narwhal

  I upgraded from Ubuntu Lucid Lynx to Maverick Meerkat with the following commands: sudo apt-get update && sudo apt-get upgrade sudo apt-get install update-manager-core sudo vi /etc/update-manager/release-upgrades and changed the last line to Prompt=normal sudo do-release-upgrade -d This upgrade was OK.

• Which email client works best with GMail IMAP?

  - by Ivan

  I use GMail (and I use labels intensively) and because of having to use a very slow Internet connection now I've came to the idea that I should try using a desktop email client. What application (Thunderbird, Evolution, Claws, or some another) works best with GMail via IMAP? First of all I want correct GMail labels support (for example an email client shouldn't think of GMail labels as of independent folders, treating messages with multiple labels as multiple different identical messages in different folders), incl. special GMail labels-folders like bin, spam, drafts and sent.

• Can't Log in to Lubuntu 12.04 X Server

  - by isomorphismes

  As of rebooting yesterday I can't login as myself to the X server part of 64-bit Lubuntu 12.04. Same problem as Can not get passed the login screen but that solution didn't work for me. Troubleshooting steps I already took: I can log in as guest (with whatever window manager) to the graphic (X) view of Lubuntu. log in as myself into a virtual terminal. (In fact I'm writing this from w3m for that reason.) So I know my password is correct and that most aspects of the system are working. One of the top google results for "can't log into lubuntu" mentioned a disk-full problem on netbooks; I don't have that problem. Let me know if I need to paste any messages or config files to make this question clearer and I'll do so. $ ls -l /home total 12 drwxr-xr-x 99 me me 12288 May 26 14:16 me $ ls -ld /tmp drwxrwxrwt 16 root root 4096 May 26 15:46 /tmp

• Man pages not finding entry

  So, I'm not sure what is going on with my system (ubuntu 12.04), but my man pages do not seem to be working.

• Restoring GRUB2 on Software RAID 0 after Windows 7 wiped it using Ubuntu 10.10 LiveCD

  - by unknownthreat

  I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

• HP EliteBook 8440p screen flickers after blank screen (nvidia)

  - by fliegenderfrosch

  When my screen turns blank after 10 min or after locking the screen and I begin using the laptop again, the screen is flickering. It looks as if every second line of pixels is blinking and the flickering is mainly present in the upper part of the screen. I am using Ubuntu 12.04 with the latest binary Nvidia drivers (current-updates). lshw | grep VGA tells me: 01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [NVS 3100M] (rev a2) The problem doesn’t occur after sleeping or on an external display. I used Kubuntu 11.10 before, where the problem didn’t occur either. Is there anything I can do except waiting for new drivers?

• Security of keyctl

  - by ftiaronsem

  Hello alltogether Today I set up an ecryptfs directory, which is automatically mounted at login via pam. To do so i followed the guide in the ecryptfs readme ecryptfs-readme To sum up, I now have a key stored in the usser session keyring. The first thing I do not understand is why this key is only showing up via keyctl show and not with the gnome-gui "Passwords and encryption keys". The second thing I am curious about is the security. I assume that my passphrase is somehow stored on the harddisk. But how exactly and how secure is this? Thanks in advance

• Should I reorder partitions regarding performance

  - by Marcel

  I have in principal 3 big partitions on my Netbook. One Windows, one for shared files, one for Ubuntu. I recently find out (using hdparm) the the hardisk seems to have much better perfomance on the first 2/3 (~ 60MB/s) than on the last 1/3 (~ 40MB/s). I am thinking to delete the second partition and create new partitions for "swap" and / directly after Windows. Does this effort make sense? I also wanna upgrade to 10.4/10.10 but keep the option to go back to the old system, so maybe I install ubuntu completely in a/this new partition?

  I've a USB bluetooth dongle root@maiko-cce-lin:~# lsusb | grep Bluetooth Bus 001 Device 007: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) that isn't working properly, hardly-ever it works but stops working in my next reboot. what I've tried it isn't software blocked root@maiko-cce-lin:~# rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hci0: Bluetooth Soft blocked: no Hard blocked: no my device is recognized by hciconfig root@maiko-cce-lin:~# hciconfig -a hci0: Type: BR/EDR Bus: USB BD Address: 00:1F:81:00:01:1C ACL MTU: 1021:4 SCO MTU: 180:1 DOWN RX bytes:330 acl:0 sco:0 events:8 errors:0 TX bytes:24 acl:0 sco:0 commands:30 errors:22 Features: 0xff 0x3e 0x09 0x76 0x80 0x01 0x00 0x80 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: Link mode: SLAVE ACCEPT but I can't turn on my hci interface root@maiko-cce-lin:~# hciconfig hci up Can't init device hci0: Connection timed out (110) I don't understand why.. the hcitool command doesn't show any device. root@maiko-cce-lin:~# hcitool dev Devices: I've tried to restart my bluetooth service too with this command and make all these previous commands again but without success. root@maiko-cce-lin:~# service bluetooth restart * Stopping bluetooth [ OK ] * Starting bluetooth [ OK ] root@maiko-cce-lin:~# The dongle works if you disconnect it from usb, wait a few seconds and connect it again. so there must be better solution for it ( a solution not involving physically removing the dongle!)
