• How do I uninstall a ruby version installed via source?

  - by Aaron McIver

  I installed a version (1.9.3-p194) of ruby via source using make install and realized this may have been the wrong route to take. Upon doing this, I realized this was a mistake and I should be using a solution such as rvm to address my ruby versions within the OS. I looked to see if an uninstall existed to be ran in conjunction with make and it didn't. I then proceeded to install rvm and add the aforementioned version in to my list of managed rubies within rvm which is not listed as ext-ruby-1.9.3-p194. rvm rubies ext-ruby-1.9.3-p194 [ x86_64 ] =* ruby-1.9.3-p194 [ x86_64 ] # => - current # =* - current && default # * - default** When I perform an rvm remove, it simply removes it from the rubies list however it still exists within /usr/local/bin. I am not concerned with the system install ruby version residing in /usr/bin as I understand that is tied to the OS and should simply be ignored. How can I safely uninstall/remove the aforementioned version and all the places in which it was installed, short of looking at the install script?

• Recommended Win2k8 Server software to fix my RAID-0 issue

  - by Jason Kealey

  I'm running an Asus P6T V2 Deluxe. It has six SATA ports and supports onboard RAID. I am using two of those ports for a RAID0 array of 1.5TB Seagate drives using the onboard RAID controller. One of them is giving me SMART warnings and I want to preemptively replace it. I pulled out two other 1.5TB drives from another computer and am ready to use one or both, if necessary. I can't run any SMART diagnostic software from within Windows because it only sees the hardware RAID-0 array, not each individual drive. The first thing I tried was a slow sector-by-sector copy using a free tool called EASEUS Disk Copy. Used the bootdisk, copied (took like 16 hours), unplugged the defective drive and plugged the new one in its place. The motherboard didn't recognize the new drive as being part of the known setup, so it did not want to boot. The second thing I tried was using other software (I forget the name) to copy the partition from within Windows. The first software failed because I had a server operating system. I found another software (I forget the name) which supported a server OS and did a partition copy onto the new drive. This seemed to work and the OS started to boot, but blue screened and started a reboot cycle. I'm assuming the software I was using was no good as it was trying to copy the boot disk while it was in use. I am looking for recommendations on what software to use to fix my problem without doing a re-install. Everything is backed up but my computer works fine and I'd like to avoid re-installation when possible. However, my system would be back up now if I had just started over on a second RAID array. :)

• Configuring Vmware virtual machines to run under different IPs and PC specs

  - by Alex

  Right now I'm using a simple VmWare virtual machine with preinstalled Win 7. The IP is assigned automatically (it's the same as main OS IP). Is it possible to create several virtual machines that have different hardware specifications and different IP addresses? Here is what I mean regarding these issues: Specs: Certainly, you can easily change some specifications in the Settings menu (RAM size, HDD size), but what about advanced settings? For example: advanced settings for the Processor: is it AMD (2500+,4000+, etc.. ) or Intel (core 2, Pentium, etc..) Ram - is it Corsair 4 Gb 1333 Mhz or Kingston 2 x 2 Gb 866Mhz or something else? Hdd - Is it Seagate Barracuda 80 gb 5400 Rpm or is it Samsung 500Gb 7200 Rpm or some random SSD? Programs that work under a Virtual Machine shouldn't have a clue if that's a VmWare or not. IPs: Every program that's launched under main OS use the real IP: 93.56.xx.xx All programs that are launched under virtual machine A use IP 1: 74.78.xx.xx All programs that are launched under virtual machine B use IP 2: 84.159.xx.xx I believe that you have to use either VPN or Proxy to solve this problem. The Sum Up: The idea is to create 2-3 independent virtual machines with different hardware specifications and IP addresses. Programs that work under a certain Virtual Machine shouldn't have a clue if that's a VmWare or the real PC. Any ideas/tips or experience regarding configuration will be appreciated!

• Why does Windows/Microsoft Updates always take such a long time to detect available updates?

  - by RLH

  It's a common task for many of us who work in any form of IT position using Windows. Eventually you have to install/re-install a version of Windows and what follows is a very long OS updating process. For a long time I have accepted the fact that this is a slow process and that's all there is to it. There is a lot to download, and some updates require restarts followed by further updates... Ugh! This morning I had to go through the process of installing Windows XP with SP3. I'm installing the OS on a VM on an SSD and I've been working on this thing for over 6 hours. Although, think there are many ways to knit-pick this process for improvements, there is one step that is always particularly slow and I can not figure out a good reason why. That step is the detection step on a manual update. Specifically, when navigate to the Windows (or Microsoft) Updates page, and then click the 'Custom' button to detect your updates. It appears that your PC just sits there for a painful amount of time. Check your Task Manager and it looks like your PC is, in fact, locked because your CPU isn't cooking but that's certainly not the case. Somethings happening but I have no clue what's going on? What is the updating software doing? If the registry was being searched, shouldn't my CPU usage peak? Does anybody know what's happening? I can loosely justify why some of the steps in the update process take so long. However, this one doesn't seem to have any reasoning.

• Dell Vostro Desktop error.

  - by goldenmean

  Faced a strange situation at work today. We have people sitting at a table on opposite sides, with power cables underneath the table. This morning when the person sitting opposite to me banged his feet on ground, it disturbed the power cable to my PC and it turned-off. So when I turned it on, it says, "No boot device found" Press F1 to setup or F5 to perform test... There was no physical impact/crash/fall of the desktop cabinet, which could have crashed/damaged the hard disk physically. EDIT: The OS is Windows 7 So I tried to recognize it in the Bios setup, but even there it could not find the SATA disk that is connected to this machine. So then I opened the cabinet, removed the power supply and plugged it back again. Tried to reboot, same error, "Boot device not found" It is not recognizing the hard disk. Any ideas about what might be wrong? Hard-disk crash, OS Crash(But it doesn't even go to the point of loading the disk after the initial Bios execution, so doubt this...) Any pointers about how I should proceed to troubleshoot/solve this error are welcome.

• .htaccess modify rules and redirect if there's .php in the url

  - by Ron

  Hello everyone. I got the following code in my .htaccess: Options +FollowSymlinks RewriteBase /temp/test/ RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^about/(.*)/$ $1.php [L] RewriteRule ^(.*)/download/(.*)/(.*)/(.*)/downloadfile/$ file-download.php?product=$1&version=$2&os=$3&method=$4 [L] RewriteRule ^(.*)/download/(.*)/(.*)/(.*)/$ download-donate.php?product=$1&version=$2&os=$3&method=$4 [L] RewriteRule ^(.*)/download/(.*)/$ download.php?product=$1&version=$2 [L] RewriteRule ^newsletter-confirm/(.*)/$ newsletter-confirm.php?email=$1 [L] RewriteRule ^newsletter-remove/(.*)/$ newsletter-remove.php?email=$1 [L] RewriteRule ^(.*)/screenshots/$ screenshots.php?product=$1 [L] RewriteRule ^(.*)/(.*)/$ products.php?product=$1&page=$2 [L] RewriteRule ^schedule-manager/$ products.php?product=schedule-manager&page=view [L] RewriteRule ^visual-command-line/$ products.php?product=visual-command-line&page=view [L] RewriteRule ^windows-hider/$ products.php?product=windows-hider&page=view [L] RewriteRule ^(.*)/$ $1.php [L] RewriteRule ^products/$ products.php [L] everything work perfect. I would like to know how can I modify it so it will be less lines. I am pretty sure I can atleast remove 4-5 lines, but I dont know how. (merge the schedule-manager, visual-command-line and windows-hider, and some more). I know that the order of the rules is important, this order works - although I have no idea why, I just played with the rules until it worked. If you think that there'll be a bug with the following order please tell me where. Another thing - I would like to redirect for example www.myweb.com/products.php to www.myweb.com/products/ (I mean that the URL in the address bar will change). I dont know if the redirect can go along with my rewrite rules. Thank you.

• How to turn off Windows Azure's "This copy of Windows is not genuine" message?

  - by Sid

  Is there any setting/configuration item to avoid Windows Azure from printing that error on the screen or detecting it? I've put a screenshot below that shows the message when you RDP into the web role. My web role runs on Windows Azure Guest OS 1.17 (variant of Windows Server 2008 SP2) Background: I was explaining our architecture to some outside engineers (NDA'd and all) and had to demystify the webrole as they were unfamiliar with Azure. I RDP'd into the VMs running the Web Role when one of their engineers gasped "are you guys running pirated copies of Windows in the cloud?" I also noticed that within the RDP screen, the Azure machines had "This copy of Windows is not genuine" on the bottom left corner. Now obviously, Microsoft is running their own OS in their own datacenter with no influence from me. So no 'piracy' here, despite that obvious warning. However, they seemed so distracted by this ("how can it be? really? hmmm?") that we wasted more time talking about it than the actual matter at work. Like I said, they have little exposure to Azure but have value add elsewhere. I want to get rid of this so I don't have to explain this in the future. PS Microsoft: If you're going to modify Windows Server <XYZ> into Windows Azure <A.B> , you should also modify the code that verifies product integrity.

• Who should I run mysql as, on a personal computer?

  - by user664833

  I just installed mysql via homebrew (with brew install mysql, on Mac OS X Mountain Lion - recently installed from scratch). Following the installation, there is a "caveats" section with options around further necessary actions to take: ==> Caveats Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysqld_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html To run as, for instance, user "mysql", you may need to `sudo`: sudo mysql_install_db ...options... Start mysqld manually with: mysql.server start Note: if this fails, you probably forgot to run the first two steps up above A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. To connect: mysql -uroot To launch on startup: * if this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist * if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded: launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist You may also need to edit the plist to use the correct "UserName". On previous versions of Mac OS X I ran mysql as mysql user, but now I am confronted by the idea of running it as myself. I am the only one who uses this computer (which happens to be my laptop), and I do programming for work and for pleasure. What are the pros & cons, or best practices, around choosing whether to run mysql AS YOUR USER ACCOUNT or as mysql or something else still?

• Protect all XML-RPC calls with HTTP basic auth but one

  - by bodom_lx

  I set up a Django project for smartphone serving XML-RPC methods over HTTPS and using basic auth. All XML-RPC methods require username and password. I would like to implement a XML-RPC method to provide registration to the system. Obviously, this method should not require username and password. The following is the Apache conf section responsible for basic auth: <Location /RPC2> AuthType Basic AuthName "Login Required" Require valid-user AuthBasicProvider wsgi WSGIAuthUserScript /path/to/auth.wsgi </Location> This is my auth.wsgi: import os import sys sys.stdout = sys.stderr sys.path.append('/path/to/project') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' from django.contrib.auth.models import User from django import db def check_password(environ, user, password): """ Authenticates apache/mod_wsgi against Django's auth database. """ db.reset_queries() kwargs = {'username': user, 'is_active': True} try: # checks that the username is valid try: user = User.objects.get(**kwargs) except User.DoesNotExist: return None # verifies that the password is valid for the user if user.check_password(password): return True else: return False finally: db.connection.close() There are two dirty ways to achieve my aim with current situation: Have a dummy username/password to be used when trying to register to the system Have a separate Django/XML-RPC application on another URL (ie: /register) that is not protected by basic auth Both of them are very ugly, as I would also like to define a standard protocol to be used for services like mine (it's an open Dynamic Ridesharing Architecture) Is there a way to unprotect a single XML-RPC call (ie. a defined POST request) even if all XML-RPC calls over /RPC2 are protected?

• VirtualBox doesn't see raw partitions

  - by smbear

  What I want to achieve is to set up virtual machine with VirtualBox. Host OS is Windows 7 Home Premium, guest will be (k)Ubuntu 12.04 on a raw partition. The first problem is that when I issue following command: VBoxManage.exe internalcommands listpartitions -rawdisk \\.\PhysicalDrive0 I get following result: Number Type StartCHS EndCHS Size (MiB) Start (Sect) 1 0xee 0 /0 /1 1023/254/63 715404 1 I'm guessing that VirtualBox is unable to see my partitions. If I use diskpart tool, then all partitions are listed correctly (note Polish language version of Windows): DISKPART> select disk 0 Obecnie wybranym dyskiem jest dysk 0. DISKPART> list partition Partycja ### Typ Rozmiar Przesuniecie ------------- ---------------- ------- ------------ Partycja 1 System 200 MB 1024 KB Partycja 2 Zarezerwowany 128 MB 201 MB Partycja 3 Podstawowy 139 GB 329 MB Partycja 5 Nieznany 4883 KB 140 GB Partycja 6 Podstawowy 50 GB 140 GB Partycja 7 Podstawowy 484 GB 190 GB Partycja 4 Odzyskiwanie 24 GB 674 GB Additional note: my PC is using EFI to boot OS. Basing on the results listed above, I believe that: I messed up with my partition table. Something is wrong with VirtualBox. Can anyone help with this issue?

• Windows 8.1 Update 1 Disk Usage 100%

  - by Gookjin Jeong

  Background Information / Computer Specs I have a 14-inch Samsung Series 5 Ultra. Core i5 CPU, 750GB HDD, 8GB RAM, Intel HD Graphics 4000. I've had the computer for about 1.5 years with no major problems. Problem The issue appeared at the beginning of April this year, when I updated the OS to Windows 8.1 Update 1 (not from 8 to 8.1). After being on continually (except for at night, when I put it on sleep mode) for about 48 hours, the disk usage as seen by Task Manager hits 100%. When this happens, everything from opening/closing applications to typing and even bringing up the start screen by pressing the Windows key becomes extremely slow. The only way to make the disk usage decrease is to restart the computer. Then the problem repeats. I've used my current laptop (as well as my previous laptops) this way -- putting it on sleep mode at night and restarting it only when Windows needs to install updates -- for a long time. So I know the 100% disk usage is not due to the way I use the computer. The thing that causes the spike varies. Sometimes it's System, sometimes it's one of the various applications I installed (e.g. Chrome, Evernote, Spotify, Wunderlist, iTunes, etc.), and sometimes it's Antimalware Service Executable, etc. Tried Solutions I think I tried almost every solution out there for this problem: Running the check disk command (chkdsk /b /f /v /scan c:) from Admin Command Prompt Running Windows Memory Diagnostic Disabling Superfetch and Windows Search from services.msc Running "Fix problems with Windows Update" from Control Panel -- Troubleshooting Updating and rolling back the graphics driver (Intel HD 4000) Disabling "Use hardware acceleration when available" from Chrome settings Disabling Intel Rapid Storage Technology Running the SFC /SCANNOW command as recommended here Running a quick scan & a full scan from Windows Defender (no threats found) Taking the hard drive out and putting it back Refreshing the computer, from the Update and recovery -- Recovery option in Windows settings NONE of the above worked for me. I was about to give up but then noticed that one of the main culprits of the disk usage spike, as shown in the "Disk Activity" section of the Resource Monitor, was C:\System (pagefile.sys). I googled around and found that one of the recommended solutions was to disable pagefile. I then went to **Control Panel -- System and Security -- System -- Advanced system settings -- Advanced tab -- Performance settings -- Advanced tab -- "Change" under Virtual memory and discovered that the number for "Currently allocated" at the bottom was 1280MB, although the number for "Recommended" was 4533MB. I immediately changed it to 4533MB and checked my family members' computers to see what the numbers were like. All of theirs had a currently allocated space that was only slightly smaller than the recommended space. See screenshot below: This might fix the problem. I'll have to wait a couple more days.But if it doesn't, what in the world should I do next? I'm guessing the hard drive isn't failing because This computer is less than 2 years old; and Speccy says that the status of the HDD is good. Update 5/27/2014 The "4533MB" solution did not work. I had to reboot the computer about 30 minutes ago because the disk usage again hit 100%. When I opened Resource Monitor the C:\System (pagefile.sys) again was shown to be the culprit. I have now disabled pagefile entirely via the same window shown above in the screenshot. The number for "currently allocated" is now 0MB. Will update again in a couple days, or if the problem occurs again, whichever comes sooner.

• Setting up Web server so it is easy to migrate

  - by Nyxynyx

  Hi I am about to move my site from a VPS to another host's dedicated server. One of my concern is about scaling the site in the future that involves a change of server. Now that I am starting the dedicated server from scratch with only the OS, this means that I need to install the web server stack, including Apache and its mods, PHP, MySQL, PostgreSQL, Tomcat, Solr and a few other softwares like ImageMagick and git. Question: Is there a way for me to setup this new dedicated server such that I can easily migrate the entire site, both the technology stack and the code to the a newer server (upgrade from this new dedicated server) easily without reinstalling and reconfiguring everything? The code for the website is being handled by git and github so thats not a problem. I'm more conerned about the rest of the software required. Side question: The current VPS uses CentOs with cpanel and it seems that many packages are outdated on yum and cpanel interfers with the installation of many packages. Which OS should I go with for the new server? Ubuntu?

• How can I measure actual memory usage from my running processes?

  - by NullUser

  I have two servers, server1 and server2. Both of them are identical HP blades, running the exact same OS (RHEL 5.5). Here's the output of free for both of them: ### server1: total used free shared buffers cached Mem: 8017848 2746596 5271252 0 212772 1768800 -/+ buffers/cache: 765024 7252824 Swap: 14188536 0 14188536 ### server2: total used free shared buffers cached Mem: 8017848 4494836 3523012 0 212724 3136568 -/+ buffers/cache: 1145544 6872304 Swap: 14188536 0 14188536 If I understand correctly, server2 is using significantly more memory for disk I/O caching, which still counts as memory used. But both are running the same OS and if I remember correctly, I configured both with the same parameters when they were installed. I did a diff on /etc/sysctl.conf and they are identical. The problem is, I am collecting memory usage and other metrics over a period of time, (eg: vmstat, iostat, etc.) while a load is generated on the system. The memory used for caching is throwing off my calculations on the results. How can I measure actual memory usage from my running processes, rather than system usage? Is used - (buffers + cached) a valid way to measure this?

• Changing the Start Menu Power Button - Setting does not work: only (Shut down) is available

  - by Martin

  This is the second time I try to change this setting on a Vista based OS and I can't get it to work again. OS: Windows Server 2002 SP2 (not R2) = Microsoft Windows [Version 6.0.6002] = Vista When I go to: Power Options - Change Plan Settings - Change advanced power settings - Power buttons and lid - Start menu power button - Setting: the available combo box will only show the option Shut down. No other options are available. This server is part of a domain and has not been set up by me. I have not yet talked with the domain admin, but as far as I could tell from googling, only Win7 has group policy options for the start menu. (And yes, OC I will talk to the domain admin to see if he has any clue - which I doubt.) (Edit: I have now talked to our domain admin, and he's got no clue either.) I'm responsible for this server and a local administrator but not a domain administrator. I switched off User Account Control (UAC) yesterday without problems. Since I always log into this machine via RDP and this being a server, the natural choice would be the option (Log out) and not (Shut down). What can I do to fix it or to find out why it cannot be changed? Thanks!

• which virtualization technology is right for me?

  - by Chris

  I need a little help with this getting this sorted out. I want to setup a linux virtual server that I can use to run both sever and desktop systems. I want a linux system that is minimalist in nature as all the main os will be doing is acting as a hypervisor. The system I'm trying to setup will be running a file server, windows 7, ubuntu 10.04, windows xp and a firewall/gateway security system. All the client OS'es accessing and storing files on the file server. Also all network traffic will be routed through the gateway guest os. The file sever will need direct disk access while the other guests can run one disk images. All of this will be running on the same computer so I wont be romoting in to access the guests OS'es. Also if possible I would like to be able to use my triple head setup in the guest OS'es. I've looked at Xen, kvm and virtualbox but I don't know which is the best for me. I'm really debating between kvm and virtual box as kvm seem to support direct hardware access.

• Shoretel Upgrade Path

  - by Brian

  I currently have a Shoretel Server running Server 2003 x32 as a virtual machine paired with a ShoreGear 90 switch and another unused switch of the same model being reserved for manual failover. I am getting the software mailed to me from my partner, but with limited support since the server is in a relatively remote area. I am tempted to upgrade the OS at the same time as performing the upgrade, but want to know if there are any horror stories or advice I should know about before diving in. I'm upgrading from Shoretel 9.2 Build. I will be upgrading first to version 10.1 then finally to 11.1. The system has been bullet proof since it was installed and we are upgrading mainly to get a client that is a little more modern. My question boils down to: Should I even bother with an OS upgrade or even possibly a fresh install of Windows with an install of Shoretel 11.1 and just transfer the configuration? Should I just stay with Server 2003 since it is supported in my target version of Shoretel and the upgrade will be more than enough to keep me busy as a novice?

• Unable to ssh in Beagle Bone Black

  - by SamuraiT

  I wanted to install pip onto beagle bone black,and I tried this: /usr/bin/ntpdate -b -s -u pool.ntp.org opkg update && opkg install python-pip python-setuptools then, it threw errors,but Unfortunately, I didn't log that errors. it was occurred a week ago and was't solved yet. I wanted to solve it now and I tried connect by ssh,but I failed. When I ping to beagle bone, it responds, and Cloud9 IDE is working too but not ssh. I don't think this is serious problem since I can connect to beagle bone by other methods: Cloud9 or so. However, to use python on beagle bone, I need to connect by ssh. Before trying to update and install python-pip, I could connect by ssh. Do you have any ideas to solve this connection problem? note I use default OS: Angstrom I don't use SD card. HOST PC is mac, OS.X 10.9 connect by USB serial I checked this but this wasn't helpful http://stackoverflow.com/questions/19233516/cannot-connect-to-beagle-bone-black I could connect by GateOne SSH client, but still unable to connect from terminal.

  I noticed weird issue when benchmarking random read I/O for files in linux (2.6.18). The Benchmarking program is my own program and it simply keeps reading 16KB of a file from a random offset. I traced I/O behavior at system call level and scsi level by systemtap and I noticed that one 16KB sysread issues 2 scsi I/Os as following.

I also use fio (famous I/O benchmark tool) and noticed the same issue, so it's not from the application. Does anybody know what is going on ? Any comments or advices are appreciated. Thanks

• Half of installed RAM is hardware reserved

  - by user968270

  After a rather arduous and convoluted series of problems that left me without a desktop for ~80 days, I've finally got the thing up and running, having replaced the power supply, motherboard, graphics card and CPU. Now, however, I'm experiencing the 'hardware reserved RAM' issue. Perhaps this is the exhaustion talking, but looking at the question that tends to get pointed to when this kind of topic gets locked as a duplicate hasn't helped. I have 16 GB of RAM installed in an MSi 970A-G46, which is spec'd for up to 32 GB of RAM. The BIOS recognizes that I have 16 GB installed, and the resource monitor also shows the whole 16 GB, only it shows 8 GB as hardware reserved. I've seen suggestions that it's an OS issue, but the particular installation of Windows 7 (64-bit) which I'm running on my boot drive is the same as the one that could actually access the 16 GB in my previous motherboard (MSi 870A-G54). I've updated my BIOS using the MSi Live Update tool and restarted the machine with no effect, and I cannot seem to locate any 'Memory Remapping' option as I've seen mentioned. I've physically swapped the RAM between the slots to no effect. I've unchecked the Maximum Memory box in the msconfig Boot tab's advanced options, also to no effect. These are my system's basic specifications OS: Windows 7 Home Premium (64-Bit) Motherboard: MSi 970A-G46 CPU: AMD FX-8150 Graphics Card: XFX Radeon HD 6870 Boot Drive: OCZ Agility 3 Storage Drive: Samsung Spinpoint F3 ST1000DM005/HD103SJ 1TB PSU: Thermaltake TR-2 TR600 600W ATX12V v2.3

• disk partition centos

  - by FlourishDNA

  I am setting up server for hosting two WordPress which has size of around 70GB. I have already installed CentOS as OS and I would like to partition the Disk. Is there any tool which can help me or can someone guide me though the process as I am not expert is SSH commands. Here are some output that might help.

• Disable internal display on Macbook Pro without closed lid mode?

  - by jslaker

  I have an early 2007 Macbook Pro running 10.5 that I've recently set up on a KVM with my primary desktop system. The problem I've run into is that I have a 20" 1680x1050 LCD, and OS X only provides options to mirror at the resolution of the built-in display or to span. Since the built-in display runs at 1440x900, this leads to running my LCD at non-native res and a fuzzy picture. There isn't any option that I can find to simply disable the built-in display entirely and run the external LCD at its native resolution. I am aware of closed lid mode, but the MBP was disassembled while in storage for about 6 months (took it apart to pull the HDD) and the cable to the touchpad, which controls the sleep sensor was damaged, meaning closed lid mode won't work. I've looked into replacing the cable, but the cheapest I've been able to find it is $75-100, and I'm trying not to invest any more money into this computer as it also has a completely dead battery and a few other minor problems. I've found the app SwitchResX which appears to allow you to do what I need, but it has a lot of functionality I don't need and a ~$20 registration charge attached to it. An odd set of circumstances, I'm aware, but I was hoping somebody might know of an OS hack that would let me just disable the internal display and be done with it. :)

• Monitor attached to motherboard is out of frequency

  - by Neilvert Noval

  I don't know if this is appropriate to ask it here in superuser. Please, just route this to appropriate stackexchange site if found unrelevant. Here's my scenario. I have bought a new motherboard (MSI 785GT-E63). I already have an old CRT monitor connected to it. After I install a linux OS to it, my monitor will display that it is: Out of frequency. Current frequency is 89Hz. The operating output of my monitor is (around) 60-70Hz. I would like to get this thing work. How can I let my CRT display properly? I was thinking of lowering down video frequency output of my motherboard, but I can't find any settings on my BIOS setup. Additional info: My monitor is attached directly to the built-in video adaptor of my motherboard. (No additional video cards) Install of OS is complete without errors. Please help.

• No network connection for vmware esxi guests

  - by JavaDev

  I'm new to VMware and setting up an Esxi server as a trial with the intention of possibly virtualizing some of our servers in the near future. I have setup ESXi on a Dell poweredge server, and installed a Centos 5.6 and Ubuntu 11.04 guest os on the server. However I cannot get networking on my guest OS's. The host is connected to a network with a DHCP server via a switch and is configured with a static IP. I have the default set-up for networking on the host: both guests are connected to the default vmnic1 adapter via the virtual switch vSwitch0. One thing though, the virtual adapter shows 'Observed IP ranges' to be XXX.XXX.XXX.194-XXX.XXX.XXX.195 (I've blanked out the initial prefixes) i.e just 1 address, even though the network the host is connected to has the usual 255.255.255.0 subnet mask. On the guest machines (using DHCP) by default, I can see an eth0 interface but with no connection or assigned IP address. A physical machine connected to the network gets a DHCP lease as expected. How do I get networking working on my guest OSes? Apologies for the long-winded question.

• Microsoft Deployment Toolkit 2012 Error

  - by Jacob Schaer

  I just started with MDT2012 recently in hopes of eventually getting away with using Ghost to deploy all of our department computers. When I test deploy in VirtualBox, it deploys the OS properly, but stops because of a network driver failure (it gets the "could not allocate resources" issue). On physical hardware (Latitude E6500, Optiplex 980, and an older Latitude) it gets through the multicast and stops immediately after with: "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information" I've looked at the logs and never see anything really of note. Originally I was using DriverPacks from DriverPacks.net, but thinking it was a driver issue, I switched over to using Dell's cab driver packs. Still the same issue. I check and it did the HDD is all fine - it was properly partitioned, set to bootable, and was loaded with all the proper OS installer files. I'm using a flash drive to do the install - when I make changes to the deployment share I rebuild and copy the ISO to the drive, then use YUMI multiboot to start the ISO (probably irrelevant).

• Debian grub2 update removed Windows boot option.

  - by Wrikken

  Since I updated grub to grub 2 I no longer get the option to boot to Windows (which is unfortunately sometimes necessary for proprietary MSIE browser plugins I need to use for work). Relevant /boot/grub/menu.lst portion: ### END DEBIAN AUTOMAGIC KERNELS LIST # This is a divider, added to separate the menu items below from the Debian # ones. title Other operating systems: root # This entry automatically added by the Debian installer for a non-linux OS # on /dev/hda1 title Windows NT/2000/XP root (hd0,0) savedefault makeactive chainloader +1 This however does not appear anymore. I do have some entries in /boot/grub/grub.cfg with entries like these: menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os { insmod part_msdos insmod ext2 set root='(hd1,msdos1)' search --no-floppy --fs-uuid --set e638c434-4884-412f-a141-2c194f881fae echo 'Loading Linux 2.6.32-5-amd64 ...' linux /boot/vmlinuz-2.6.32-5-amd64 root=UUID=e638c434-4884-412f-a141-2c194f881fae ro quiet echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-5-amd64 } Do I have to alter that file? If so, what is the correct syntax for a Windows boot? If not, what could be the problem?
