• Installing 64-bit Ubuntu Server 12.04 LTS, on a VM with VMWare Player, on a 64-bit Windows 7 PC

  - by WannaBeAGeek

  I'm trying to create a VM, using VMWare Player, with an ISO image of Ubuntu Server 12.04 (LTS). The machine I'm doing the installation on has an Intel(R) Core(TM) i5 CPU, and runs 64-bit Windows 7 I managed to create the VM (gave username, password, configured network etc), but I can't install Ubuntu Server. First I get this alert : Binary translation is incompatible with long mode on this platform. Disabling long mode. Without long mode support, the virtual machine will not be able to run 64-bit code. For more details see http://vmware.com/info?id=152. When I click OK, I get another alert : This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible. This host supports Intel VT-x, but Intel VT-x is disabled. Intel VT-x might be disabled if it has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting. (1) Verify that the BIOS/firmware settings enable Intel VT-x and disable 'trusted execution.' (2) Power-cycle the host if either of these BIOS/firmware settings have been changed. (3) Power-cycle the host if you have not done so since installing VMware Player. (4) Update the host's BIOS/firmware to the latest version. For more detailed information, see http://vmware.com/info?id=152. Then, when I click OK, my VM exists, and I get back to the VMWare Player home screen. I don't know much about hardware and virtualisation, so there might be some necessary info I'm not giving. Please don't hesitate to let me know what is missing in my post, for finding solutions. Thanks :)

• Daemons did not start automatically ubuntu 10.04

  - by Anton Prokofiev

  Hello, All! I have a strange behavior on Ubuntu 10.4: few daemons (apache2 and postgresql (8.4SS from enterpriseDB) did not start automatically. Funny things that time-to-to they do. (If I just restart my computer everything looks ok, but if I turn it off for the night, nothing work..., so I have to start them manually) I've googled this problem a little bit, but the only answer I have found was to run: sudo update-rc.d apache2 defaults I've called it but the answer was: System start/stop links for /etc/init.d/apache2 already exist. Any Ideas?

• Install Navicat for MySQL on Linux Ubuntu 12.04

  - by DanielAttard

  How do I install Navicat on Ubuntu Desktop 12.04? I have just configured a new Ubuntu 12.04. Because I'm not so familiar with the command line, I prefer to use Ubuntu Desktop so that I can have a GUI. Now I need to install a front-end to connect with MySQL. I prefer to use Navicat in a MAC environment, so I was hoping to install Navicat on the Ubuntu machine. I downloaded a Linux copy of Navicat for MySQL from here: http://www.navicat.com/download/navicat-for-mysql The problem I am having is that I don't know how to install the program after it has been downloaded. There is a navicat.exe file in the navicat folder, but that seems to be for a DOS/Windows environment. I just can't figure out how to install Navicat onto Ubuntu Desktop 12.04. Anyone have any ideas? Thanks.

• KVM and libvirt: How to configure a new disc device to an existing VM?

  - by initall

  I've got an Ubuntu 9.04 server running two VM's. In /etc/libvirt/qemu/machine1.xml two disk devices are defined like this: <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/vserver/machine1/disk0.qcow2'/> <target dev='hda' bus='ide'/> </disk> <disk type='file' device='disk'> <source file='/vserver/machine1/disk1.qcow2'/> <target dev='hdb' bus='ide'/> </disk> I need more storage space in at least one of the devices and thought about adding a third hdc device by simply adding one with same style as above and re-organising my mount structure (The virtual sizes of the current qcow2 files are unfortunately limited.) My problem is that reloading libvirtd and restarting the VM do not result in a new visible device (checked with fdisk). I'm aware of extending an existing qcow2 file (converting to raw format, cat-ing/adding the new one, using smth. like gparted) - but only as a last resort. Hopefully it's something very simple I'm missing?

• How To Create An FTP User That Has Permission To EVERYTHING

  - by Serg

  I've spent the last two hours trying to create an FTP user so I can transfer some files over to my Wordpress blog folder. /var/www/sergiotapia.me I'm using vsftpd and Ubuntu 12.04 for my FTP server and I've read tons of documentation, none of which seem to work. I still cannot log in with the FTP user, let alone test if I even have the read/write file permissions. Can a Linux guru here, help me out with a small step by step? I'm comfortable with the terminal and nano, so that's not an issue - I'll SSH into my box. Just tell me what to do and what commands to run. Specifically, this user needs to have read and write access to the /var/ folder and anything within it. I want to have 1 user that can do whatever the heck he wants on my Ubuntu 12.04 VPS machine.

• Still no external sound after installing ubuntu 10.04

  - by Walter

  As suggested I upgraded. Same as before except now not even the speaker control in the application bar. Please help. Background: I have Ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal and ran alsamixer which seems to recognize my sound card, though the driver is not listed in System Administration Hardware Drivers; the only driver listed is my graphics card. Setup: I have a Dell 8250. Speakers are plugged into the SB live card. Woofer and 2 speakers using transformer.

• Using MongoDB + Redis + Apache on the same server in production?

  - by Dayson

  I intend to launch my web app using a 8 GB VPS. It uses MongoDB + Redis for storage/caching and Apache + PHP-FPM for serving requests. Could there be any issues with running Mongo + Redis + Apache on the same server? Would it make more sense to setup 2 x 4 GB VPS servers and keep Mongo on one and Redis + Apache on another? Should I just start with one server and worry about scaling horizontally later by delegating the existing server to Mongo in the future (due to its large RAM) and moving the web servers on to multiple smaller VPS'?

• All network devices freezing when Airport Extreme Base Station is connected. Any ideas?

  - by Jon

  I've been troubleshooting this issue for a while, and through a series of events have it narrowed down to my airport extreme base station. I like this router, since I'm able to connect to IPV6 sites without any insane configuration (my alternate router is too old and doesn't support v6). My question is: Has anyone else had this issue, if so how is it resolved? If not, can you recommend a good IPv6 router? Here is how I came to the conclusion that it is the router: Devices: XBOX 360, HTC Incredible, Home-Built machine running FreeBSD, Home-Built machine running Ubuntu 10.04. 1.) Noticed freezing on Ubuntu Box. 2.) Noticed freezing on XBOX360 3.) Noticed freezing on HTC Incredible (only when connected to my network wirelessly). The above all happened at random times throughout the past few weeks. Over the last few days, I was playing XBOX and noticed that the XBOX and Ubuntu machines both froze. I picked up my phone, and it was also frozen. I reset all devices, power-cycled my router, and all was fine again. About two hours later, it happened again (I was playing Forza III, the XBOX froze; I went to the Ubuntu box and it was frozen; unfortunately, the HTC phone was not connected wirelessly, and the FreeBSD box was turned off). I can't even begin to imaging what a router could be doing to freeze devices with such differing hardware/software/OS, and I feel absurd for coming to this conclusion, but I have nothing else. I hooked up my archaic Netgear router, and have had no problems since. :(

• How do I access files inside a Wubi virtual ext4 Ubuntu partition from within Windows?

  - by aalaap

  I just installed Ubuntu 10.04 using Wubi on a PC that has Windows XP and Windows 7 installed. I was working in it for a while and everything is just fine. However, when I booted back into Windows 7, I couldn't figure out a way to access the files I had created or downloaded into the Ubuntu partition. They're in a virtual disk called root.disk in my C:\ubuntu\disks. Is there a way I can mount this vhd into Windows or at least browse the contents and extract what I need?

• misaligned raid partition in Ubuntu 10.04

  - by Linux Jedi

  I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space. Then I went into system-administration-disk utility. In there I went to file-create-RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array. After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested." What do I do now? As far as I can tell, the partitions are identical.

• Which repo and version of Percona for Natty?

  - by thefella

  I'm wanting to drop in Percona instead of MySQL (5.1) on my Natty ubuntu server. I've added the keys and the repos. I've added a natty repo, even though it's not supposed to exist and it seems to be fine. The problem is when I go an apt-get install percona-server-server, it tells me that it depends on percona-server-server-5.5 and won't be installed. Should I just install 5.5 (over the top of mysql 5.1) or do I need to install percona 5.1? Or do I need to pick a different repo and let it decide?

• Link to a folder in the top Ubuntu panel

  - by Seamus

  Hi. I like the little top panel thing in Ubuntu. I have links to all my most used programs on there. (Which is why I don't see the point of docky or any of those things: they seem to do the same job, but they're messier). What I'd like is to have a little icon for my documents folder up there too. But I don't seem to be able to do it. It's not one of the options listed when you go to "add to panel...". Am I missing something ridiculously easy?

• PHPMyAdmin HTTP auth works, but not cookie auth

  - by ssmy

  I'm running PHPMyAdmin version 3.3.2 on Ubuntu 10.04, fully updated. Recently, the authentication for PHPMyAdmin stopped working. It would return the error 1045. However, login on the command line still worked. I switched to HTTP authentication instead of cookie auth, and now it works fine. Any ideas why this could be, or what I could do to make cookie auth work again? (Partly just to know, and partly since it's a bit nicer).

• Ubuntu 11.04: No Audio Output

  - by Jason George

  I installed a fresh copy of Ubuntu 11.04 earlier this week and I'm having trouble getting my audio online. It was working fine in 10.04 and all the resources I can find on troubleshooting seem to be fairly dated so I'm not sure if they apply. CMI8788 [Oxygen HD Audio] Analog Stereo Duplex Playing a WMA file shows 0.00db output when I mouse over the sound controller in the status bar. Obviously, no output from my speakers. I tried adjusting the profile, thinking I might have the wrong one. That seems to have made things worse. Where mouse over originally said something along the lines of "Oxygen HD Audio," it now reads "Dummy Output." Selecting "Test Speakers" in sound preferences crashes the dialog. Any pointers would be great.

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• How to start a service at boot time in ubuntu 12.04, run as a different user?

  - by Alex

  I have a server ClueReleaseManager which I have installed on a Ubuntu 12.04 system from a separate user (named pypi), and I want to be able to start this server at startup. I already have tried to create a simple bash script with some commands (login as user pypi, use a virtual python environment, start the server), but this does not work properly. Either the terminal crashes or when I try to ask the status of the service it is started and I am logged in as user pypi ...? So, here the question: What are the steps to take to make sure the ClueReleaseManager service properly starts up on boot time, and which I can control (start/stop/..) during runtime, while the service is running from a user pypi? Additional information and constraints: I want to do this as simple as possible Without any other packages/programs to be installed I am not familiar with the Ubuntu 12.04 init structure All the information I found on the web is very sparse, confusing, incorrect or does not apply to my case of running a service as a different user from root.

  I am new to Linux. I am compiling Linux kernel (ver: 2.6.34.12) in gcc in traditional manner in VMware machine in Ubuntu (kernel version - 2.6.38-8-generic) 11.04 version. I am unable to find, where to update about newly compiled kernel in the grub.cfg file. I updated the newly created image version name in the existing image. Then VMware didn't able to load new kernel. I have searched in internet but I didn't find. So anyone can help me, to update in the grub.cfg and to successfully load new kernel. Few things about what I have done: Make bzImage to create image file. Make modules_install && make install to install modules and then sudo mkinitramfs -o initramfs.img-2.6.34 2.6.34. Then sudo gedit grub.cfg. In that at the mementry I updated the version of vmlinuz and initrd from 2.6.38-8 to 2.6.34.12. This is I have done.

• Ubuntu 11.04 hangs at "checking battery state" while booting

  - by MisterSir

  When I try to boot Ubuntu 11.04, it just hangs when it gets to checking battery state. I know this issue is usually related to graphic drivers, but it worked like a charm for months now. Last time I was on Ubuntu I updated my system with the update manager, so maybe an update caused it. Anyway, I really need Ubuntu. I'm in the middle of work on a website and I have a deadline, so I need some help over here. Thanks. p.s. I tried reinstalling gnome-power-manager. Didn't work. And I'm not on a laptop.
