• How to use ssh-agent (and graphic passphrase dialog) in Kubuntu 10.10?

  - by halo

  I have recently switched from Ubuntu to kubuntu, both version 10.10. Unfortunately in KDE the ssh passphrase dialog doesn't work out of the box. Everytime my ssh private key is used I need to enter my password. This is neither secure nor comfortable. I have done comprehensive research on the net but only found out dated documentation. Several things I tried didn't work out. Current status: SSH setup working with direct passphrase input ssh-agent running in X session $SSH_AUTH_SOCK set to ssh-agent's socket in X session How to enable ssh-agent for keeping the passphrase in memory for ~15mins and as a bonus always use a graphical dialog for its input? I use asymmetric SSH key pairs for pushing/pulling in Git VCS logging remotely into different server systems

• How to access both partitions on a bootable USB flash drive in Windows

  - by Maccyjam

  I have a 16GB USB Flash Drive that is partitioned into two different sizes. The first partition contains a bootable version of Ubuntu, the second partition is for general saving of files. Windows will only recognise the first partition. I have tried using Bootice but this breaks the bootable partition. Disk Management recognises the second partition but does not allow me to do anything with it. Is there a way to make both partitions accessible by Windows and keep the USB disk bootable?

• Long lag and errors clicking gmail links in google chrome

  - by Doug T.

  I recently downloaded Google Chrome with Ubuntu 9.04 and love it. Ironically one site I consistently have issues with is gmail. When I enter gmail I will click a link, say an email or the inbox link. After a very long wait (on the order of 30 seconds to a couple of minutes) my page will load with an error such as: Some Gmail features have failed to load due to an Internet connectivity problem. If this problem persists, try reloading the page, using the older version, or using basic HTML mode. Learn More. Googling the symptoms has not helped. Has anyone else had any similar issues? Has anything helped?

• Putting a whole linux server under source control (git)

  - by Tobias Hertkorn

  I am thinking about putting my whole linux server under version control using git. The reason behind it being that that might be the easiest way to detect malicious modifications/rootkits. All I would naively think is necessary to check the integrity of the system: Mount the linux partition every week or so using a rescue system, check if the git repository is still untempered and then issue a git status to detect any changes made to the system. Apart from the obvious waste in disk space, are there any other negative side-effects? Is it a totally crazy idea? Is it even a secure way to check against rootkits since I most likely would have to at least exclude /dev and /proc ?

• Taking over and Moving a PHP site

  - by KCavon

  I have a internal use PHP site at my new position. It only runs a few days a year off site so we keep it on laptops. The hardware it has been on, a 8 year IBM Thinkpad running Fedora, is dying. I have new Lenovo Thinkpad's running latest and greatest Ubuntu. I have copied the contents of var to a shared drive, renamed the old www folder in var on the new machine and copied over the old www folder. I can get to the login page and into the site, but when I look something up it returns Cannot Open. I know I cannot get to the MySQL in the new machine because users and passwords dont match. The version of the PHP from the old machine is before the setup script was included. I know very little about PHP. I am looking for input on the proper way to link the old PHP files to my mysql instance. Any help, much appreciated.

• What are the pros of switching DNS names with a database server hardware upgrade?

  - by wilbbe01

  When we upgrade to new hardware at work we usually increment a number in the DNS name. For example. We have a server called database-2, that is slated to become database-3 in the coming days. I haven't been able to find a good reason why this is good behavior. To me the work of trying to catch all end user machines, as well as all servers dependent on the database server is far riskier than simply moving the database and ip/name with it to the new hardware. A little over a year ago we spent several months of requests coming in, as infrequent users began using software that needed to be updated to point to a new DNS name. I am struggling to find answers as to why this is a good practice. So the question. Why is using DNS names as a "server hardware version identifier" a good idea? What am I overlooking? Thanks much.

• windows 2003 download utility from command line , http or ftp or any other protocol , from one comma

  - by Michael

  Hello , I need to know if there is anyway utility bult-in windows 2003 that I can use from the command line to download a file using only one command. Basically I know that I can download from ftp using the "ftp" utility but in order to do that I need to do first "ftp open" and then pass the other commands so it doesn't help me because I need to do perform the download only from one command. The download may be performed through http, ftp or any other protocol.

• Can't unlock locked screen, in Ubuntu 12

  - by Camille Goudeseune

  After locking the screen (with a keystroke bound to xlock -nice 8 -mode blank), I can unlock the screen as expected, but only within a few minutes. After being locked overnight, when I hit a key (even Ctrl+Alt combos), the screen stays black with just a brief white flash across the middle of both monitors. The workaround is to ssh in from another host and restart X. Some months ago, this happened every few weeks. By now it happens almost every morning. How do I even start to diagnose this? What might I look for in log files? (The intermittency is particularly troubling.) Failing that, is there an alternative to xlock aka xlockmore? Hardware: 3-year-old HP minitower, GEForce 9800 GT, two Asus LCD monitors. Software: Ubuntu 12.04.2 LTS. Window manager awesome-wm. NVidia driver 304.88. XLock version xlockmore-5.31.

• What happened to QuickTime Pro for Windows editing features?

  - by Tod

  I used to record screencasts in SnagIt and then edit them in QuickTime Pro on windows with no problem. I haven't done it in a few months and now when I try most of the editing features have gone whack-a-doodle. For instance, if I got to delete a few seconds of video, it actually ends up deleting 20 seconds of video. I have repeated this on various source files including the Sample.mov that comes with QT. Using Edit-Cut looks like it works, but it doesn't actually do anything. Trim still works but that appears to be it. I know at least one other person has confirmed this behaviour. Does anyone have any work arounds. I'm using Windows 7 64 bit. QT Info QT Pro 7.7.1 (1680.42) QuickTime Version 7.6.8 (1675)

• How to prevent firefox from updating

  - by Larry

  I have firefox 3.6.x in Mint Linux. For physical problems -- eyes and color, I want to keep this version and not do any updates ever to it. I don't know if it is a firefox or linux issue, but nothing seems to work. It should not be rocket scientist enabled. :P This is what I have tried: Update Manager and added to ignore package --firef0x* Fully removed all traces of firefox and reinstalled 3.6.28 In firefox, set the upgrade options (3) of them to unselected and saved. Scanned computer for firef* to insure all traces were removed, to include /usr/bin/firefox. Using Mint Linux 9, otherwise fully upgraded for packages. That's the main things I've done. My major issues is the later versions of that software are almost impossible for me to see.

• ESXi disaster recovery plan

  - by Marlin

  I have a Vmware infrastructure where I am using the free version of Esxi 5 . I cannot as a result use vmotion and the other cool features that come with a paid ESXI. I am using snapshots for the backups but they are stored on local hard drive. I need a better backup scenario where I can recover in the event of a harddrive failure. I tried openfiler but could not get it right. What backup method can I try given my situation?

• Spoof MAC address in Windows 7: Bypass

  - by lpd

  I am trying to spoof the MAC address of my new Win7 laptop. To do so I tried specifying an alternate value from the Device Manager which took no effect. I also tried from the registry, as per other threads here, to no avail. Interestingly I also found the registry contained a path 000X\Ndi\params\NetworkAddress\default REG_SZ, but changing that had no effect either :( I can only guess I share the same issue here: http://forums.anandtech.com/showthread.php?t=2096480 as the wireless adaptor is the same brand bundled with the same operating system. So my question is - is there anything better I can do to achieve a spoofed physical address than rollback the drivers to some older version?

• OEM Windows 8 Downgrade to Windows 7

  - by user1873048

  I recently Purchased an ASUS K55A As you may know, all Windows 8 machines come with a BIOS that contains 'Secure Boot'. This basically makes sure that the BIOS won't load anything other than the Windows 8 OEM bloatware version that comes with new Laptops. However the Asus Bios allows for me to disable the secure boot, and therefore I should be able to revert to Windows 7, Linux, etc. Drivers may or may not be supported. When I put my MINT LINUX boot disc in CD-R Drive and try to boot from ISO, nothing happens. There isn't even a boot priority list in this BIOS... I can provide screen shots later. It just says WINDOWS 8 Bootloader and also on the other tab it says WINDOWS 8 BOOT OVERRIDE Has anybody purchased a windows 8 machine and successfully loaded windows 7 or Linux?

• Default maximum heap size -- Ubuntu 10.04 LTS, openjdk6-jre

  - by sachin

  I just installed openjdk6-jre on Ubuntu 10.04 java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu1~10.04.1) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode) Every time I run "java" I get this error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. This can be solved by specifying a maximum heap size and running "java -Xmx256m" But is there anyway to permanently fix this error (i.e. set the default heap size to 256MB so that I do not need to specify the max heap size every time I run the command)

• Bluetooth headset turns off when Skype call ends

  - by Claude

  For about 6 months, I haven't been able to use Skype because when I end a Skype call, my Plantronics Callisto headset gets turned off. I'm paralyzed so I can't turn it on manually. I have a Sony VAIO computer running Windows 7. I have updated my Bluetooth dongle software, uninstalled and reinstalled Skype and uninstalled Skype and gone back to an earlier version; all to no avail. Neither Plantronics nor Skype technical support are interested in looking into this problem for me.

• Updating solr on a ColdFusion 9 install?

  - by Jordan Reiter

  I'm thinking about upgrading the solr install included with ColdFusion 9 to the latest Apache release. This raises a few questions: Is there a compelling reason not to upgrade to 3.6 (is it slower than, more cumbersome than, or backwards-incompatible with 1.4) altogether? The solr install included with CF9 is customized. Is there a way to customize it myself, or to at least fool CF into treating it like its predecessor? Will all of my existing indexes work as-is (are?) with the new version? Has anyone out there on ServerFault done the upgrade? I'm especially interested in hearing about unforeseen or unexpected effects from the upgrade.

• X server not starting up after new kernel compilation

  - by tech_learner

  I have compiled the Kernel on my 64-bit Debian XPS Studio 1340 Dell system. srikanth@debian:~ - 05:40:52 PM - $ uname -a Linux debian 2.6.32-5-amd64 #1 SMP Thu Mar 22 17:26:33 UTC 2012 x86_64 GNU/Linux Kernel version that I have used and compiled from kernel.org is 2.6.35.13 I have nvidia installed on old kernel. I got the old config and I used the same config to compile the new kernel. Everything went well and I got two debian packages ( image and headers ) which I have installed on my system. When I select the new kernel on the boot menu and I go into it, the X server is not starting up possibly because I have to "rebuild" ( not sure how to do that ) according to this link: http://www.linuxquestions.org/questions/slackware-14/x-server-not-starting-after-kernel-compilation-605265/ Can you suggest how to do the rebuild on nvidia module so that I can start x ( without seeing any blank screen or error saying nvidia module is missing ) ? PS: The link that I have used to compile the kernel is https://help.ubuntu.com/community/Kernel/Compile#Alternate_Build_Method:_The_Old-Fashioned_Debian_Way

• PHP 5.2.13 doesn't work on Windows 7 on apache 2.2

  - by Sinan

  I have a test server on a Windows 7 Machine with apache 2.2 installed. On it PHP 5.2.11 was workig fine (as a module). But when I try to install 5.2.13 (or greater). It doesn't start. Nothing beside the PHP version is different. I unzip the files and add the lines. LoadModule php5_module "c:/PHP/php5apache2_2.dll" AddType application/x-httpd-php .php PHPIniDir "c:/PHP" But that LoadModule directive doesn't let apache start. When I comment that line apache starts. When I replace the files with those in 5.2.11 package Everything works fine again. Does anyone have any ideas?

• Cisco: changing VTP mode server/client to transparent

  - by J. Smith

  I have around 40 L2 switches (2960, 3560, 3500, 3750) running in VTP client mode and one L3 switch (6500) running in VTP server mode, all connected together. I would like to switch everything in VTP transparent mode without any interruption of service. I've already test on a poc version with 3 switches (Catalyst 2950, 3560 and 3750). Using serial and SSH connection, it is seems working but i'm not sure it is enough representative compare to the real network. Knowing that the VTP Pruning is enabled, I am wondering what would be the best procedure to proceed the changement. I've read that we could lost connection by keeping it enabled. Should I change the server or clients first? Is it important to change the VTP domain and VTP Pruning parameters?

• How would I measure the amount of RAM needed per Glassfish domain? [closed]

  - by oligofren

  Possible Duplicate: Can you help me with my capacity planning? In our test environment we have a lot of apps spread out over a few servers and Glassfish domains. To make versioning easier I would have liked to have one Glassfish domain per customer per app (kind of like a heavyweight version of lots of jetty instances). But I have heard that Glassfish is kind of heavy on the resources, and so I would need to measure approximately how many instances would fit in the available RAM. These are low-traffic/low load testing servers, so CPU is not really an issue, though RAM might be. How would I get an approximate measure of how much RAM is needed? This is one Glassfish 3 instance with one heavy EAR application deployed. top? jvmstats? ??

• Reset my windows server 2003

  - by Tim Thoirp

  I was recently given an HP Proliant Server from a friend as a gift. It has Windows Server 2003 installed on it. When I go to boot the system however to log in to Windows Server 2003 it requires an Admin password. I can't figure out the password and my friend doesn't know it either as it has been years since hes used the machine. I don't care about any of the data on the machine I just want to have a new clean version of Windows server 2003 running on it. Any advice would be helpful? And no I don't want to pay for a password cracking tool. Thanks

• How to install Python 2.7 w/ unix libs on cygwin

  - by JIStone

  I have been trying for about a week to get this to work. Obviously getting Python 2.6 is easy - just install the cygwin package with setup.exe. Installing the windows version of Python2.7 was also easy, but I could not access the Unix Modules. So I've been trying to install Python from source, but it seems every time I fix one make error there is another waiting just behind it. Getting rather fed up with the whole thing & thinking someone else must have either done this or figured out it is impossible. I feel installing Linux would have been the easier route . . .

• 7.0.1 and Photoshop openGL requirements

  - by mcgd

  Hi, I'm running Workstation 7.0.1 on a 64-bit Linux host, with a Vista guest, and the Aero theme works a treat - full marks for getting that working! However, when running Photoshop there are some operations (like interactive image rotation) that seem to require graphics support that VMWare doesn't have - attempting to do these operations returns an error that the functionality "only works with OpenGL enabled windows". It seems that it needs OpenGL 2.0 and Shader Model 3.0 which I gather are supported under Workstation 7 - do I need to put in additional settings of some kind? I've updated to the right version of VMWare Tools, and the video driver is listed as "VMWare SVGA 3D (Microsoft Corporation - WDDM)". I see that in 6.5 there was an option to switch between the beta WDDM driver and the SVGAII driver, but I assume the features of both of these would have been merged into the standard driver in 7.0? Thanks -Matthew
