• Ubuntu 13.10 has no Suspend or Hibernate Options

  - by Charlie Davies

  I have a Lenova Yoga 2 Pro, and I have Ubuntu 13.10 installed. I am having some issues setting the power functions. At the moment I can not suspend or hibernate the laptop. So from Gnome 3.10 I have the option to Log Out, Shutdown & Restart. No option for Suspend / Hibernate. Weirdly however I can use these commands to get the right behaviour sudo pm-suspend sudo pm-hibernate So the laptop knows how to do this, it just is not giving me the option and also when I set "Close screen lid" to suspend, well nothing happens. It feels like there is a "connection" not being made.

• Dependency Injection: where to store dependencies used by only one method?

  - by simoneL

  I developing a project integrated with Dependency Injection (just for reference, I'm using Unity). The problem is that I have some Manager classes with several methods and in many cases I have dependencies used only in one method. public class UserManager : IUserManager { private UserRepository UserRepository {get;set;} private TeamRepository TeamRepository {get;set;} private CacheRepository CacheRepository {get;set;} private WorkgroupRepository WorkgroupRepository {get;set;} public UserManager(UserRepository userRepository, TeamRepository teamRepository, CacheRepository cacheRepository , WorkgroupRepository workgroupRepository, ... // Many other dependencies ) { UserRepository = userRepository; TeamRepository = teamRepository; CacheRepository = cacheRepository ; WorkgroupRepository = workgroupRepository; ... // Setting the remaining dependencies } public void GetLatestUser(){ // Uses only UserRepository } public void GetUsersByTeam(int teamID){ // Uses only TeamRepository } public void GetUserHistory(){ // Uses only CacheRepository } public void GetUsersByWorkgroup(int workgroupID){ // Uses only workgroupRepository } } The UserManager is instantiated in this way: DependencyFactory<IUserManager>(); Note: DependencyFactory is just a wrapper to simplify the access to the UnityContainer Is it OK to have classes like that in the example? Is there a better way to implement avoiding to instantiate all the unnecessary dependencies?

• ESXi onboard SATA passthrough [on hold]

  - by lodge93

  I am running ESXi 5.5 on a home system. When I attempt to pass one of the onboard SATA controllers (Intel ICH10R) to a VM, it is successful. However, the controller never appears in the VM. What else am I missing that would cause a VM to not recognize the controller? Additional Info: The controller is set to AHCI mode in the BIOS Prior to setting up the controller for passthrough, ESXi did recognize the controller and the drives I have tried with multiple VMs, none of which recognized the controller or the attached drives I have two onboard SATA controllers, on controller for ESXi and one for passthrough The final ideal state is that I could passthrough the controller to a FreeNAS VM

• Why is only one domU giving me the "time went backwards"?

  - by Paul Tomblin

  I'm setting up a replacement server for one that was working ok but is having hardware issues. The original server is i686 (Pentium III), but the new one is amd64 (Xeon). Everything is working fine, except one of the three domUs is giving me the "clocksource/0: Time went backwards" error. The Debian Wiki says what to do if all your domUs are getting this error, but not what to do if only one of them has. The "tenants" on my domUs have done some messing about with the systems I configured for them. I don't know what the user of that particular domU might have done.

• How can I turn off flash fill automatically in Excel 2013?

  - by user3480643

  Flash fill breaks a lot of things in older excel documents. It causes maddeningly slow transfers from cell to cell after updating. I am trying to find a way to turn off "flash fill" in Excel 2013 automatically before rolling the product out to the rest of the staff in my company. Is there (preferably) a registry key that I can apply or a switch that I can include during the install that will turn this option off? Here is an image of the setting that I am looking to turn off: I haven't been able to find any documentation online about turning this off, other than this one page from MS: http://office.microsoft.com/en-ie/excel-help/turn-flash-fill-on-HA104043292.aspx

• Video driver reports 8-bit color depth after Windows Update

  - by user3163

  Windows Update pushed out a new video driver for the Mobile Intel(R) 4 Series Express Chipset Family. One HP 6730b laptop was updated from 8.15.10.1872 to 8.15.10.2021. After the update the color depth is reported as 8-bit even if the setting is 32-bit. This means that Areo effects are disabled. Downgrading to 8.15.10.1872 did not help. Is there any way to force the video driver to report 32-bit color depth?

• iptables block everything except http

  - by arminb

  I'm trying to configure my iptables to block any network traffic except HTTP: iptables -P INPUT DROP #set policy of INPUT to DROP iptables -P OUTPUT DROP #set policy of OUTPUT to DROP iptables -A INPUT -p tcp --sport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT The iptables output (iptables -L -v) gives me: Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 4 745 ACCEPT tcp -- any any anywhere anywhere tcp spt:http state RELATED,ESTABLISHED Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 2 330 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http state NEW,ESTABLISHED When I try to wget 127.0.0.1 (yes i do have a web server and it works fine) i get: --2012-11-14 16:29:01-- http://127.0.0.1/ Connecting to 127.0.0.1:80... The request never finishes. What am I doing wrong? I'm setting iptables to DROP everything by default and add a rule to ACCEPT HTTP.

• Most efficient RAID configuration with 6 disks?

  - by Bob King

  I have a hand-me-down server that I'm setting up at home and it's got 6 72Gb hard disks (as well as 2 18Gb drives that I'm using for the OS). What is the best way to configure those 6 drives? Should I RAID 5 or 6, or go with something simpler, like mirroring? I'm planning to use it to hold a source control repository, and possibly data for a development SQL server. The machine has a hardware raid controller. It is an old IBM server.

• Load-balanced Linux server across internet?

  - by LinuxGnut

  I'm investigating setting up a load balanced server solution consisting of three CentOS 5.4 boxes. Two of these boxes will reside in one facility, while a third will reside in a different facility. I'm currently working to set up heartbeat, ldirectord, ipvsadm to load-balance the machines, but I'm not sure its going to work with I'm not overly familiar with the details behind how all of these work, but is the load balancing going to work correctly when these servers are not all on the same LAN? I'm not sure if heartbeat is using SNMP to send signals or not, which would only work over a LAN. Has anyone tried this or found a different solution?

• ADFS http login failure not re-requesting credentials

  - by Devnull

  We have ADFS working with HTTP (401) login. If a user types their password incorrectly, ADFS barfs and requires that the browser be closed, rather than asking the user for to attempt to log in again. Reprompting for user credentials is the typical behavior with other web servers (even IIS). This appears to be an artifact of setting the HTTP session, but other HTTP-login applications dont behave this way. We are having additional issues now because some users are saving that password, and its causing them account lockouts because the browsers do not realize they need to update saved credentials. Anyone know of a workaround? Wed rather not enable forms login if possible.

• Recovering data from a Silicon Image SiI3114 RAID

  - by Isaac Truett

  I have a set of 3 disks in RAID 5 originally created with a Silicon Image SiI3114 on-board RAID controller. The old motherboard is dead. The new motherboard (which has a different raid controller) won't boot from the array. I have no reason to believe that the drives are damaged or corrupted. I'm 99% sure that the problem is that the new controller isn't compatible or I'm not setting it up properly. Is it possible to recover data from the drives using a different controller? Would a PCI card like this one allow me to read from the array again?

• Create my own custom ellipsis bullet point

  - by Airn5475

  I regularly use an ellipsis as a bullet point in a list of items in Word/Outlook 2010. Example: I like summer because... ... it's warm out. ... we go on vacation. ... my birthday is in July. Currently in Word/Outlook if you type certain characters like a hyphen and hit space, it will automatically start a bulleted list using the hyphen. I would really like the same functionality with the ellipsis. When I type the third period and hit space, start a bulleted list. Does anyone know of a way to do this? Registry hack? Hidden Word Setting?

• MySQL - complete server migration (Ubuntu) [closed]

  - by Mr A

  Possible Duplicate: How to copy and move mysql database Dump all databases with SSH access I'm setting up a new dev machine, and I have the old one sitting right next to me. I'd like to do an exact copy of all MySQL structures and data from the old machine to the new. Nothing fancy needs to happen (it's a dev machine). No replication. I don't care about "downtimes" etc. Is there a super simple way to do this? For example, I have SSH on the old server, can I just use Nautilus, do a connect to server, and then transfer a folder over, replacing another folder with it and be done? It's the same version of MySQL on both sides. Same version of Ubuntu. Same in most respects.

• Slow speed for UFS mounted drive in Linux

  - by Incredible

  Hi, I have a disk that has Sun OS disk, (ufs filesystem). And I want to mount it in my debain machine with read/write mode. Since by deafult linux doesn't support write to ufs filesystem. I had to recompile the kernel by setting to the flag CONFIG_UFS_FS_WRITE=y. Now I am able to write to the filesystem, but the read/write speed is very slow. It is around 120 KB/s. Any idea what is wrong and how to resolve this issue? Thank you in advance.

• Thunderbird "Folders" and "Inbox" font size

  - by bo gusman

  Graphical programs are such a pain sometimes. I am of an age where 1024x768 is the highest resolution that I can see. I had set my Windows 7 system fonts to be 125% - that helps a lot - but it screws up the tool bars on many other programs so I've reverted to 100% and it's now too hard to read in many cases. Most browsers will let you easily scale text font size as will the "message" window of Thunderbird (aside from setting the default font size for reading messages to 24 point, CTRL + + works wonders). However, I cannot seem to find a way to set the font size for the other panes - the Folders pane and the inbox pane. Is there some undocumented way to do that?

• Named my RPi 512MB @jerpi_bilbo

  - by hinkmond

  To keep our multiple Raspberry Pi boards apart from each other, I've now named my RPi Model B w/512MB: "jerpi_bilbo", which stands for Java Embedded Raspberry Pi - Bilbo (named after the Hobbit from the J.R.R. Tolkien stories). I also, set up a Twitter account for him. You can follow him at: @jerpi_bilbo He's self-tweeting, manual prompted so far (using Java Embedded 7.0 and twitter4j Java library). Works great! I'm setting him up to be automated self-tweeting soon, so watch for that... Here's a pointer to the open source twitter4j Java library: download here Just unzip and extract out the twitter4j-core-2.2.6.jar and put it on your Java Embedded classpath. Here's how @jerpi_bilbo uses it to Tweet with his Java Embedded runtime: import twitter4j.*; import java.io.* public final class Tweet { public static void main(String[] args) { String statusStr = null; if ((args.length 0) && (args[0] != null)) { statusStr = args[0]; } else { statusStr = new String("Hello World!"); } // Create new instance of the Twitter class Twitter twitter = new TwitterFactory().getInstance(); try { Status status = twitter.updateStatus(statusStr); System.out.println ("Successfully updated the status to: " + status.getText()); } catch (Exception e) { e.printStackTrace(); } } } That's all you need. Java Embedded rocks the RPi! And, @jerpi_bilbo is alive... Hinkmond

• php.ini settings change not taking effect for large file uploads

  - by user51347

  My server was just reprovisioned, and my application which uploads large (100M+) files now breaks upon re-installation. the symptom is quite consistent : smaller files (8mb in my tests) upload just fine. Larger files cut off at quite close to the same point every time given a particular computer. a file that fails at 26% will fail at just about the same every time. One that takes 1:40s to fail will take within 2 seconds of that every time, before failure. I have set my php.ini settings extravagently : post_max_size = 512M upload_max_filesize = 512M max_input_time = 3600 max_execution_time 3600 Is there possibly a setting at the Apache Level which would override PHP?

• Ensure a process is running on a remote computer

  - by awilinsk

  We have about ten client computers ranging from Windows XP to Windows 7 that have a little program that runs in the tray. This program needs to be running at all times and sometimes it either crashes or a user exits the program. We would like to be able to check every hour or so to see if this program is running. If it is not running, it should be started. I have tried using powershell on one of our servers to get the process from a remote computer and if it doesn't find it, to start it. But, that fails because it cannot start the process as an interactive user. I tried setting up a task in task scheduler, but Windows XP task scheduler is not very good or configurable. We would like this to be as easy to administer as possible. What would be the best way to do this?

• How can one make the title bar text have better contrast on dark colors in Windows 8?

  - by zeel

  When Windows 8 color setting are set to a very dark color, such as black or navy blue, the title bar text and the minimize/maximize buttons are nearly invisible. This makes dark colors difficult to work with. In Windows 7 there was an advanced color options, this is gone in 8. The registry keys associated with this seem to still be present, but they have no effect. Is there a way to change this? Or a third party application that can do it? I don't want to use the ugly high contrast theme, I want to use the nice Win 8 theme with a dark color.

• How can I connect a wired PC to the internet through my Macs wifi connection?

  - by David Weitz

  So I'll probably be buying a USB wifi adapater if I can't get this to work, but I'm trying. I have a wireless router at home and my Macbook Pro is connected to said wifi. My desktop doesn't have a wifi connection, but I've connected my macbook with my desktop via crossover cable. I enabled internet sharing on my macbook, but my Windows 7 desktop can't get a connection. I tried just regular file sharing and that works fine, but the internet sharing doesn't. I assume the goal is to get my PC to see my mac as the default gateway, but I've had no luck manually setting it. Here's the ifconfig output on my mac and my attempt at settings on windows: http://i.imgur.com/uJfUz.png

• Windows Media Player functionality for Ubuntu

  - by Xeoncross

  I have way to many music files to bother with setting up playlists. Especially since my files locations keeps changing as I move stuff around and swap between different computers, different mount points, and even different Operating Systems! So managing my media with any application is doomed to failure. However, since I still want to listen to the music I usually just select all the files I want to play at a time and then right-click to open them in a media player. Works great in windows media player and places all the tracks in a temp playlist on the sidebar. Fails in ubuntu using Rhythmbox since it doesn't understand "temp" playlists and just keeps adding files to your FULL listing of all sings on your whole computer. I have over three copies of some tracks now in my audio collection - and all of them are now invalid because the location of the files has changed. So what media player (for Ubuntu) works well with just temporary playlists and will allow me to open up my files without adding them to a collection?

• How to schedule download of windows 7 updates?

  - by atoMerz

  To put it short: I'd like to schedule my windows updates to start/stop at certain times of day. How can I do this? More explanation: This is because my internet traffic is limited by ISP and it's free only during a specific period throughout the day (2:00am-7:00am). I've set windows update setting to check for updates but notify me before downloading in order to prevent it from automatically using up my traffic. But then I have to manually tell it when to start downloading. I obviously don't want to stay up that late just to push a button. So again, how can I schedule windows updates to start/stop at specified times?

• Critical (Unixlike) Distros for Sysadmin Hopefuls to Have Experience With

  - by Interwebs

  Hi All, I'm trying to learn to be a Unix/Linux Sysadmin, and am hoping to get some hands-on experience by setting up a few installs (VMs, old comps, and the like) at home and practicing administering them. I was wondering, in the experience of those on this site, which distros are critical to be comfortable with. Obviously, to a certain extent, they're all similar, but there are substantial enough differences between administering, say, Debian, OpenSolaris, FreeBSD, and CentOS. So, which distros are most important to practice with in your opinion? Which have had most demand/come up most often in actual work situations? Thanks!
