• Do I really need twho different Exchange servers 2007|2010?

  - by lrosa

  Given am Exchange Server 2003 running on a dedicated server on a LAN protected by a Linux in DMZ, Microsoft says that if you upgrade, you should install two different servers (meaning two boxes, two licenses of Windows Server and two installations of Exchange) with different Exchange "server role". Exchange is installed in a safe LAN, there is a Linux relay in DMZ that feeds messages to Exchanges and gets from it the messaged to be delivered on the Net (smart relay). The mail traffic is about 2000 Internet messages/day and probably another 2000 msg/day sent by local users within the organization. The servers hosts 200 users.

• Help with the RT3290 Wireless adapter

  - by Potek

  I know there is a lot of questions about RT3290 wireless adapter, but I read many many of them and noone helped me with my problem. So, I have the HP Pavilion dm1 laptop and I installed Xubuntu 13.10 on it. During the instalation it poped up that I'm able to connect to the internet via network adapter. I did it obviously, but it worked for like 5 seconds, then it said that network connection is down and I couldn't connect to my router, even if i could actually see network connections avaible. Then (when installation ended) I rebooted my computer. My network was avaible! I could connect and browse the internet smoothly. Next day I turned on my laptop and I saw my wireless connection is no longer avaible, so I plugged laptop to the internet via Ethernet cable and started to explore internet searching solution for my problem. I did this: How do I get a Ralink RT3290 wireless card working? And I was able to connect BUT my kernel started to panic every time I started Mozilla or any program that is connecting to the internet. Every tip i searched was almost the same as the link above. I tried to do this many ways. I even Reinstalled Xubuntu to do everything with clear system but the same thing happened. THEN I installed Linux Mint to check whether it is a major or just Xubuntu problem. Linux Mint responded even worse, because I wasn't even able to use terminal (I clearly messed something up). I would really, really appreciate every help, because I do want to solve this problem and finally be able to use Xubuntu/Ubuntu. I'm waiting for advice from anyone patiently. If anyone wants some details, just tell me which ones.

• How To Convert Virtual Machines Between VirtualBox and VMware

  - by Chris Hoffman

  Migrating to another virtual machine program can be intimidating. if you already have your virtual machines set up they way you like them, you don’t necessarily have to install them from scratch – you can migrate your existing virtual machines. VirtualBox and VMware use different virtual machine formats, but each supports the standard Open Virtualization Format. Convert your existing virtual machine to OVF or OVA and you’ll be able to import it into another virtual machine program. Unfortunately, this may not always work perfectly, as VirtualBox and VMware both seem to use slightly different OVA/OVF implementations that aren’t entirely compatible. If this doesn’t work, you may want to reinstall your virtual machine’s guest operating system from scratch. 8 Deadly Commands You Should Never Run on Linux 14 Special Google Searches That Show Instant Answers How To Create a Customized Windows 7 Installation Disc With Integrated Updates

• NTFS Error - file system structure is corrupt and unusable

  - by SomeGuy

  My Windows 7 (64) keeps completely locking up, and I have to hold the power button to shit it down. Event logs are showing EventID 55. I realize that this can be a warning sign of an impending disk failure, but my data on this machine is safely backed up and I don't feel like taking the time to replace the drive right now. When I have seen this problem before, I have been able to delete the offending folder with a Linux Live CD. (When CHKDSK /F didn't work). In this case, the folder is from VSS. I assume this is from Crashplan, my online backup provider. What are the ramifications of deleting this folder from Linux? Is it safe to do? "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy26."

• Unable to mount NTFS Partition after resizing

  - by sam

  I was having only 15 GB space allocated to LINUX. I wanted to have more space available to linux. So I just re sized one of my ntfs partition using GParted. But after resizing I am not able to open the partition neither in Ubuntu nor in windows. OS: Dual Boot Win7/Ubuntu 10.10 The error message i get is the following: Error mounting: mount exited with exit code 12: Failed to read last sector (395458824): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

• Why is Thunar not creating and showing thumbnails of images?

  - by darenw

  Thunar is my main file manager. Normally it automatically creates thumbnail images of all images in the directory being viewed. After experimenting with other Linux distros then installing Arch Linux once and for all, Thunar is not showing thumbs. Image files all get the same generic image icon. Googling turned up some information: Something called gvfs needs to be installed. I have it. Still no go. (Apparently this isn't actually needed anyway.) Someone had this problem and fixed it by running some mime-related command (I didn't save any notes) I did this same command but no go. Checking the obvious: in Thunar's Edit/Preferences, yes, the [x] Show thumbnails is turned on. When I view one image in GIMP or EOG, the generic icon in Thunar is replaced by a thumbnail. But only for that one file I opened.

• capture nimbuzz traffic

  - by lurscher

  I need to capture all the traffic, specially during login, between nimbuzz pc client and nimbuzz server. The reason is that i need to debug outgoing packets at login that mark the user visibility status in order to reproduce them in a in-house XMPP client application I've tried doing this with wireshark, but i seem to be pretty helpless with this tool. Also, the packets i've been able to see are all before the SASL negotiation happens, after that, i cannot see the xml packets being exchanged any help for how to achieve this task is greatly appreciated (preferably on Windows, since there is no nimbuzz client for linux, in any case i can install one in a VM and monitor the traffic between the VM instance in the linux host)

• How do I make a USB stick from which to install different OS's?

  - by Hanno Fietz

  Recently, I have made a number of USB sticks to install OS's (several Linux flavors, BSD, Windows) from, on machines that didn't have CD drives. Now, I would prefer to not overwrite the install USB sticks all the time, since it's handy to have them, but neither do I want to pile up USB sticks that I only need every 6 months. It would be great to have a bootable USB stick that fires up some minimal system, lets you choose an ISO image and then reboots from there. How would I go about this? Do I use some minimal Linux? Is there some kind of modified / specialized boot loader? Can I set up GRUB to do this? Should I use virtualization?

• Advice for migrating email server

  - by Chris Adams

  Hi there, I'm planning to migrate a Zimbra server with about 200gb of data from a server hosted in an office into a datacentre, to increase uptime (we've had a couple of outages when our network here started flaking out, and we have people in other countries relying on this server too). However, I'm not sure how best to migrate the data into the data centre without rendering the connection unusable during office hours, because there's far too much to send in over night over the two meg upstream connection we have here. I'm familiar with using tools like nice to stop a long running process degrading machine performance - is there a simple way to throttle a connection between office hours, so the long running transfer doesn't block the pipe, but then opens up outside of office hours to make the most of the bandwidth? I'm aware the alternative here is to simply mail a hard drive to the data centre, but I'd like to avoid doing that if I could. We're using Centos Linux for our servers, in the office and the datacentre, so extra points for an open source linux answer.

• How can I assign actions to all my mouse buttons?

  - by Torben Gundtofte-Bruun

  I have a mouse with lots of buttons, but it's not a mainstream make like Logitech. For Windows, I have a driver that lets me assign actions like close-window (Ctrl+W) or next-tab (Ctrl+Tab), but I don't have a Linux driver. Since Linux is so flexible, I thought perhaps there is a general way to do this, regardless of brand? Update: Based on input from Cyrex, I installed and ran sudo apt-get install btnx which found several but not all mouse buttons. Found: left, right, wheel, wheelclick, thumb fwd, thumb back. Not found: wheel left, wheel right, thumb middle button. Vendor ID is 0x04d9, Model ID is 0xa015. Update 2: In SystemPrefsMouse there's a lightbulb icon for testing double-click speed. Every working button can turn the bulb on&off, but the missing buttons can't. It would seem that Ubuntu isn't aware of these buttons and thus doesn't register their clicks. I guess I need to hunt for a driver, though a mainstream mouse is probably the easier way.

• Lubuntu 12.04 on Acer laptop boots to blank blue screen

  - by WGCman

  My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

• Generic tool to configure startup applications on Unix

  - by srid

  Is there an automated deployment tool that manages startup applications on a variety of machines, especially the Unices? Or is the only hope to study the nuts and bolts of each Unix (osx, linux, solaris, hpux, aix) on how to configure applications to launch on system startup? I want to run them as a specific user, instead of root. At the moment, I run them all within a screen session .. which is a hassle, as this requires manual intervention every time the machine is rebooted for some reason. Ideally, I am looking for a tool that would read, say, ~/.startup-programs which file contains, on each line, the command line to launch the needed daemons. And this tool should work on OSX, Linux, Solaris, HPUX and AIX ... writing the appropriate startup scripts for each platform.

• SD Card only mounted after a reboot

  - by hattenn

  I have a Kingston 2GB MicroSD and I plug it in via an inconix MicroSD Adapter to the internal card reader of my Samsung N210 Netbook with Ubuntu 10.10, but it doesn't show up. Only if I reboot the system when the card's plugged in it shows up. Why does it need a reboot for mounting? sudo fdisk -l gives the output below. But I can only see the drive when I reboot the computer while the card's plugged.

• Contract-Popup at Login

  - by Steve

  I want to give my notebook to guests of my little Hotel as an extra service. I love the Ubuntu guest-account and I think that this is the best possible way to help my guests get free internet-access. I found out how to "design" their user-accounts with /etc/skel, but unfortunately I have no clue, how to show them a small introduction to the system and a kind of user-agreement "contract" when they login. I read of xmessage, but this is too minimalistic. I'd like to implement some pictures. Does anyone have any idea of how to make this possible? Would it be possible that the user is logged out automatically if he rejects the user-agreement? Thank you so much in advance, Steve.

• glibc not found when trying to install Absinthe?

  - by RafLance

  I am trying to install Absinthe 2.0.4 on Ubuntu 11.10 on a netbook. When I try to run the install file, this keeps on happening: rafael@RafLaptop:~/Desktop/absinthe-linux-2.0.4$ ./absinthe.x86 ./absinthe.x86: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./absinthe.x86) Do I need to upgrade GLIBC? If so, how do I do that? Since I'm on a netbook I can't use a LiveCD so I wanted to know if there was a way I could fix this issue without reinstalling my whole OS. Any explanations about what GLIBC is exactly would be great too since this is a learning experience for me. I know that GLIBC is a part of libc.so.6 and so I tried to run sudo apt-get install libc.so.6 but was told that it was up to date. But GLIBC isn't? I hope this articulates my problem well, if there are any pieces of missing info or questions to clarity my question, please let me know! ~-~ EDIT/UPDATE: So after some help on the AskUbuntu chat room from user izx, I have gathered the following information/understanding: -I need to run this program with Ubuntu 12.04 or recompile it from source -Upgrading libc on Oneiric to 2.15 while possible, is not an easy task and is not officially supported.

• Disable discrete AMD GPU

  - by Smajl

  My notebook has two graphic cards and it suffers from severe overheating after installing Ubuntu (no problem with Windows 7 on the same machine). I figured out that the problem may be in the graphic card and I would like to disable the discrete one. I followed some tutorials on this topic (for example http://planetoss.com/articles/how-to-disable-the-discrete-amd-graphics-card-in-linux/). But the problem is, that after executing the commands, nothing really happens and both GPU are still running. Here is what I have done: smajl@smajl-mini:~$ sudo chown smajl /sys/kernel/debug/vgaswitcheroo/switchsmajl@smajl-mini:~$ echo IGD > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 smajl@smajl-mini:~$ echo OFF > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 What am I missing here? Also, more on the overheating topic: 1) Installed TLP 2) updated system 3) set power setting mode to "power save" ...and nothing helps Tried same thing with Linux Mint without success. Is there anything else to try if I manage to disable the second GPU and the problem preserves? Otherwise I would have to get back to win in order not to melt my laptop.. :-/

• screen does not wake up after suspend/ brightness will not adjust

  - by Nathan

  My computer is one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16834230467 Asus Zenbook UX32A-DB51 Just bought it yesterday. Set to "suspend" when I close the lid, but when I open it up again I just get a black screen. Pressing the power button doesn't work, not does clicking the mouse or any key combination. The same is true if I leave the computer until it suspends. Black screen, no response, have to reboot. I also can't seem to adjust the brightness. I put "brightness up" and "brightness down" function keys in, and when I push them it shows the brightness level as going up and down on the meter, but the screen does not actually become more or less bright. I am totally new to all of this. Please tell me what additional information you need to help me and where I can find it. Thanks! Edit: Tried the following: sudo gedit /etc/default/grub Change the line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="acpi_osi=Linux" sudo update-grub Restart your linux And "acpi_backlight=vendor" both to no avail.

• Screencasting with explanation boxes

  - by Bakhtiyor

  I wanted to make a video demonstration of one software. I wanted to use text description instead of using voice description, a simple example of what I've explained could be this short screencasting, where author uses short text messages instead of explaining it with his own voice. Could you recommend any free software for doing such a screencasting please? Would be better if it works in Ubuntu or if it is a web application. UPDATE I have found out Wink which could add explanations boxes as I said. Now the problem is that it doesn't support Linux 64bit, has only 32bit. Any other app like Wink for 64bit Linux?

• Cannot login via Unity login screen after upgrade to 12.04

  - by codesurgeon

  Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message - my user account and credential verification seem to be OK. I suppose that my individual graphics configuration causes problems ... I'm not sure how to reset that. I've tried stopping the UI via sudo service lightdm stop executed sudo nvidia-xconfig and restarted the UI sudo service lightdm start to no avail. My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07. Anybody have an idea how to get this fixed?
