• Encouter error "Linux ip -6 addr add failed" while setting up OpenVPN client

  I am trying to set up my router to use OpenVPN and have gotten quite far (I think), but something seems to be missing and I am not sure what.

• Handling bounced email when using a postfix smarthost

  - by Mark Rose

  I'm running a high availability cluster, and so far, most things work great. I have two external machines that act as outgoing mail hosts (smarthosts). The internal hosts are configured to relay all email through these two external facing hosts. My smarthosts' main.cf looks like this: myhostname = lb1.example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases mydestination = lb1.example.com, localhost relayhost = mynetworks = 127.0.0.0/8 10.1.248.0/24 My internal hosts' main.cf looks like this: mynetworks = 127.0.0.0/8 myhostname = web1.example.com mydestination = $myhostname, localhost.$mydomain, localhost relayhost = [10.1.248.3] smtp_fallback_relay = [10.1.248.2] lb1's internal IP is 10.1.248.2, and lb2's internal IP is 10.1.248.3. On the external hosts, email for root and www-data is forwarded to [email protected] with /etc/aliases. One advantage to using the smarthost setup is that spam filters and the like can connect back to the sending sending server. All email is sent fine, and headers look like this: Received: from lb2.example.com ([198.51.100.3]) by mx.google.com with ESMTP id y17si1571259icb.76.2011.01.13.18.20.32; Thu, 13 Jan 2011 18:20:32 -0800 (PST) Received-SPF: neutral (google.com: 198.51.100.3 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=198.51.100.3; Received: from db1.example.com (unknown [10.1.248.20]) by lb2.example.com (Postfix) with ESMTP id D364823C0BE for <[email protected]>; Thu, 13 Jan 2011 21:20:31 -0500 (EST) Received: by db1.example.com (Postfix) id C9FA7760D6A; Thu, 13 Jan 2011 21:20:31 -0500 (EST) Delivered-To: www-data@localhost Received: by db1.example.com (Postfix, from userid 0) id C1632760D6C; Thu, 13 Jan 2011 21:20:31 -0500 (EST) The problem is bounced/reject email. The external machine tries to forward the email back to the internal machine, e.g. www-data on web1 sending an email that bounces (such as a user signing up with a bad email address). An additional complication is using Google mail for the main example.com domain. In lieu of specifying every internal host in the external hosts' mydestination, is there a better way of setting things up, keeping in mind I can't adjust touch the mx for example.com?

• Php pdo_dblib - cannot find/unable to load freetds

  - by MaxPowers

  Self-hosted box, RHEL 6 PHP 5.3.3 PDO installed freetds installed pdo_dblib - so far no luck installing My goal is to use PDO with sybase. Attempting to install pdo_dblib from the appropriate version php source code. I have tried a variety of methods and searched quite a bit for help on this topic, but have yet to be successful. Method 1 Install freetds $ ./configure $ make $ su root Password: $ make install This is successful Install pdo_dblib inside the /ext/pdo_dblib folder: $ phpize $ ./configure $ make $ make test Error output: PHP Warning: PHP Startup: Unable to load dynamic library '/home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so' - /home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so' - /home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so' - /home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library '/home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so' - /home/sybase/Install_items/php_533_src/php-5.3.3/ext/pdo_dblib/modules/pdo_dblib.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 That doesn't look good...I researched this and found an interesting hack for this here. But changing pdo.ini to pdo_0.ini was not the solution, as I still got the same errors on make test. $ su $ make install Output: Installing shared extensions: /usr/lib64/php/modules/ That seems strange...and no, it doesn't actually install (not showing up on phpinfo after apache restart). Method 2 Install freetds following the instructions exactly, i add the prefix $ ./configure --prefix=/usr/local/freetds $ make $ su root Password: $ make install This is successful Install pdo_dblib inside the /ext/pdo_dblib folder: $ phpize $ ./configure --with-sybase=/usr/local/freetds This produces the following error at the bottom of the output ... checking for PDO_DBLIB support via FreeTDS... yes, shared configure: error: Cannot find FreeTDS in known installation directories Method 3 freetds ./configure variation (including or not include the --prefix...) did not change the result of this so I'll skip it. Install pdo_dblib pecl extension following the method specified here. pecl download pdo_dblib tar -xzvf PDO_DBLIB-1.0.tgz Removed the line, <dep type=”ext” rel=”ge” version=”1.0?>pdo</dep> Saved the package.xml file, and moved it in to the PDO_DBLIB directory. mv package.xml ./PDO_DBLIB-1.0 Navigated to the PDO_DBLIB directory, then installed the package from the directory. cd ./PDO_DBLIB-1.0 pecl install package.xml But, this command gives me the following error output, same as Method 2. checking for PDO_DBLIB support via FreeTDS... yes, shared configure: error: Cannot find FreeTDS in known installation directories ERROR: `/home/sybase/Install_items/pecl_pdo_dblib/PDO_DBLIB-1.0/configure' failed

• Looking for definitive answer to accessing a network drive/NAS/SMB drive via Windows 7 HOME and Windows 7 Professional. Is it possible and how?

  - by Rob

  I want to be able to access my Lacie 2Big network drive in Windows 7 Explorer. I have a machine with Windows 7 Home and one with Windows 7 Professional. Neither Windows 7, home or pro, can access the drive. The Windows 7 Home machine displays the drive in its Explorer, with the capacity, but on clicking the icon, I get another window, blank with the busy pointer which does not eventually stop. The drive is working perfectly. How do I know this? Because I can access it with no problems on my Apple Mac, Windows XP home and Ubuntu machines on the same network as the Windows 7 machines. Except for the Windows XP home machine that required Lacie ethernet agent program, the Mac and the Ubuntu machines needed no setup, the drive appeared like any other drive. So my 2 questions: Is it possible to access a network share drive, e.g. a NAS like Lacie 2big in Windows 7 Home Premium and Windows 7 Professional. If so how? I read on Microsoft's own forums and elsewhere that network sharing drives, e.g. via SambaSMB is NOT possible on Windows 7 Home. Is this true? http://social.technet.microsoft.com/Forums/en-US/w7itprovirt/thread/e08c3500-a722-4b44-b644-64f94f63c8e5/ This question is a more comprehensive re-write of my earlier question: Windows 7 / TCP/IP network share guide - looking for to resolve failure to mount lacie network drive but works on XP,Linux,Mac. ...where I haven't received a solving answer, and I have tried to find a solution myself. Lacie themselves haven't offered a definitive solving answer either, but I suspect it's not just their drives but SMB/network share/NAS in general... This is utterly pathetic that Windows 7 home cannot access something as simple as a network drive, especially given that Windows XP home can. My research so far: Apparently it is possible on Windows 7 Professional, via the Local Security Policy, only on Windows 7 Professional, not Windows 7 Home: http://www.sevenforums.com/tutorials/7357-local-security-policy-editor-open.html http://answers.microsoft.com/en-us/windows/forum/windows_7-security/accessing-local-security-policy-in-windows-7-home/0c8300d0-1d23-4de0-9b37-935c01a7d17a http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/14fc5037-3386-4973-b5d8-2167272ff5ad/ http://www.tomshardware.com/forum/75-63-windows-samba-issue Another solution offered is editing the registry, doesn't look promising to me, fiddly and not guaranteed, hard to produce a complete solution I think, given that everyone's registry can vary.

• Can't clone gitosis-admin.git local from my snow leopard server running gitosis

  - by joggink

  I've installed gitosis as described here: http://gist.github.com/264304 One of the things that I had to adjust was to give my git user permissions to use ssh (which I did trough server admin - access - ssh and added the 'git' user). When I ssh from my local machine (mac osx) as the git user, I get this response: PTY allocation request failed on channel 0 bash: gitosis-serve: command not found Connection to 10.0.0.108 closed. Which I think is normal, because in Pro GIT the author says you should get something like this if you try ssh'ing to the server using your git user: PTY allocation request failed on channel 0 fatal: unrecognized command 'gitosis-serve schacon@quaternion' Connection to gitserver closed. So far so good, I think? Now when I try to clone my gitosis-admin.git repository using this command: $git clone [email protected]:gitosis-admin.git I get this: Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ bash: gitosis-serve: command not found fatal: The remote end hung up unexpectedly So after doing some searching, I found an answer here on serverfault claiming I should use ssh:// as protocol for my git clone (which I thought is the default git protocol?) However, when I try: $git clone ssh://[email protected]:gitosis-admin.git This is the response: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts. Password: Password: Password: Permission denied (publickey,keyboard-interactive). fatal: The remote end hung up unexpectedly When I type in my own password (because my git user has no password), I get following error: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts.

• Automating video generation by adding an intro and a trailing video to the main video

  - by DevDewboy

  I have a video project I am trying to compile. Here is the overview: I have many videos which are 5 minute training sessions - Main video. The Intro Video will be a standard 5 second video that will have the Video title and Author. This will be concatenated to the main video. The Trailing Video will pretty much be a stock video that will be concatenated to the main video and have all the legaleze etc. The Intro Vid will smoothly fade into the main vid as well as when you get to end of the main video it will fade into the Trailing video nicely. The product is a new video with a Intro, Main & Trailer video all in one! The concept is really that simple. In fact I found an example of a person who has solved this and is doing exactly what I want. This solution is a Bash script that takes a config file that has the title, author, etc. and generates the Intro, the Ending and creates the resulting video with them concatenated. I am using Ubuntu 12.04 Server. I have been trying to take this as a sample and just running it with no luck because of incompatibility errors. I even attempted to convert it using .MP4 containers or .MKV. I am running into error after error or incompatibility issues. I went as far as changing out the ffmpeg binary using the 25 Oct 2013 version from http://ffmpeg.gusari.org/static/64bit/ which I like as I don't have to worry about rebuilding the binary. Almost successful but again I have some error which I cannot solve. I know part of the problem is the fact that video production, codecs, formats is a completely new field for me so I am attempting to work through this new territory. Perhaps an expert here has something similar that I can use as a guideline that uses MP4 or h.264 format. Or take the solution above from the URL and make it work with a more up-to-date version of ffmpeg. I will include the script and its parameter file and the output (abbreviated because of limitation) below. Basically as the script stands right now, when run I get the error [matroska,webm @ 0x27bbee0] Read error. This error is return from the 'reasembleVideo' routine from the first ffmpeg command. The following is the Parameter File: #!/bin/bash INPUTFILE="ssh_main.mp4" LOGO="logo.png" LOGOLENGTH="1" SPEAKER="Jason" TITLE="Basic SSH Video" DATE="October 28, 2013" SCENESTART="00:00:01" SCENEDURATION="00:00:09" OUTPUTFILE="ssh_basic_1" } The following is the script I am running. The ${OUTPUTFILE} being used is a small 2 minute video I create in screen-o-matic in MP4 format. Script on PasteBin (too long for Super User post)

• Installing gnome on Linode with Ubuntu 9.10 x64 - remote VNC/RDP

  - by Kieran Benton

  Hi, I'm a self confessed Linux newbie, having lived and worked mostly within the Windows world for most of my life. I'm making the effort to try moving my virtual host from a Windows box to a Linode instance to try and better learn Linux, and one of the uses I occasionally have with my current Windows VPS is to RDP into it and browse the internet. I'm aware that this is probably not best practice (from either performance or security), and most of the time I will be learning from the shell, but I do occasionally need to boot into a GUI. Because of this, I'd like the ability within my Ubuntu installation on Linode to start/stop Windows X and Gnome at will after SSHing in (startx? gdm?), so I've tried: apt-get install ubuntu-desktop Reboot startx But I've got an error that no amount of googling has helped me with so far, which I'm assuming is something to do with the fact the box is headless and X needs some more configuration that is beyond me at the moment: root@local:~# startx hostname: Unknown host xauth: creating new authority file /root/.Xauthority xauth: creating new authority file /root/.Xauthority xauth: (argv):1: bad display name "local.kieranbenton.com:0" in "list" command xauth: (stdin):1: bad display name "local.kieranbenton.com:0" in "add" command X.Org X Server 1.6.4 Release Date: 2009-9-27 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-23-server x86_64 Ubuntu Current Operating System: Linux local.kieranbenton.com 2.6.31.5-x86_64-linode9 #1 SMP Mon Oct 26 19:35:25 UTC 2009 x86_64 Kernel command line: root=/dev/xvda xencons=tty console=tty1 console=hvc0 nosep nodevfs ramdisk_size=32768 ro Build Date: 26 October 2009 05:19:56PM xorg-server 2:1.6.4-2ubuntu4 (buildd@) Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

• dhcp-snooping option 82 drops valid dhcp requests on 2610 series Procurve switches

  - by kce

  We are slowly starting to implement dhcp-snooping on our HP ProCurve 2610 series switches, all running the R.11.72 firmware. I'm seeing some strange behavior where dhcp-request or dhcp-renew packets are dropped when originating from "downstream" switches due "untrusted relay information from client". The full error: Received untrusted relay information from client <mac-address> on port <port-number> In more detail we have a 48 port HP2610 (Switch A) and a 24 port HP2610 (Switch B). Switch B is "downstream" of Switch A by virtue of a DSL connection to one of Switch A ports. The dhcp server is connected to Switch A. The relevant bits are as follows: Switch A dhcp-snooping dhcp-snooping authorized-server 192.168.0.254 dhcp-snooping vlan 1 168 interface 25 name "Server" dhcp-snooping trust exit Switch B dhcp-snooping dhcp-snooping authorized-server 192.168.0.254 dhcp-snooping vlan 1 interface Trk1 dhcp-snooping trust exit The switches are set to trust BOTH the port the authorized dhcp server is attached to and its IP address. This is all well and good for the clients attached to Switch A, but the clients attached to Switch B get denied due to the "untrusted relay information" error. This is odd for a few reasons 1) dhcp-relay is not configured on either switch, 2) the Layer-3 network here is flat, same subnet. DHCP packets should not have a modified option 82 attribute. dhcp-relay does appear to be enabled by default however: SWITCH A# show dhcp-relay DHCP Relay Agent : Enabled Option 82 : Disabled Response validation : Disabled Option 82 handle policy : append Remote ID : mac Client Requests Server Responses Valid Dropped Valid Dropped ---------- ---------- ---------- ---------- 0 0 0 0 SWITCH B# show dhcp-relay DHCP Relay Agent : Enabled Option 82 : Disabled Response validation : Disabled Option 82 handle policy : append Remote ID : mac Client Requests Server Responses Valid Dropped Valid Dropped ---------- ---------- ---------- ---------- 40156 0 0 0 And interestingly enough the dhcp-relay agent seems very busy on Switch B, but why? As far as I can tell there is no reason why dhcp requests need a relay with this topology. And furthermore I can't tell why the upstream switch is dropping legitimate dhcp requests for untrusted relay information when the relay agent in question (on Switch B) isn't modifying the option 82 attributes anyway. Adding the no dhcp-snooping option 82 on Switch A allows the dhcp traffic from Switch B to be approved by Switch A, by virtue of just turning off that feature. What are the repercussions of not validating option 82 modified dhcp traffic? If I disable option 82 on all my "upstream" switches - will they pass dhcp traffic from any downstream switch regardless of that traffic's legitimacy? This behavior is client operating system agnostic. I see it with both Windows and Linux clients. Our DHCP servers are either Windows Server 2003 or Windows Server 2008 R2 machines. I see this behavior regardless of the DHCP servers' operating system. Can anyone shed some light on what's happening here and give me some recommendations on how I should proceed with configuring the option 82 setting? I feel like i just haven't completely grokked dhcp-relaying and option 82 attributes.

• Random servers in Citrix servers suddenly bluescreens (mostly 0x0000008e and 0x0000007e)

  - by Rasmus Rask

  I'm responsible for a Citrix Presentation Server 4.5 farm. Starting Friday 30. November, my servers started to crash randomly. So far we've experienced 80 crashes, so it's obviously becoming an increasingly big problem for us. I have 12+ years experience with IT, so I know the difference between 0 and 1, but I have a hard time cracking this. We've rolled back any recent changes I can think of for different groups of servers, but all groups still seem to crash. I don't have the skills to interpret the memory dumps to find the culprit. Has anyone encountered the same or a similar problem? - might be a generic Windows issue Other than executing "analyze -v" in WinDbg, how do I work my way through the memory dumps to see what actually triggered the BSOD? Any suggested steps in getting to the bottom of this? Any help is greatly appreciated. I can also provide links to kernel memory dumps or WinDbg output if necessary. Thanks! Problem description The majority of the STOP errors we encounter are: 0x0000008e KERNEL_MODE_EXCEPTION_NOT_HANDLED (50%) 0x0000007e SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (26%) 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA (21%) We also see a few 0x0000000a IRQL_NOT_LESS_OR_EQUAL (3%). For both 0x0000008e and 0x0000007e bug checks, the exception code is 0xc0000005 (Access Violation). When opening dump files in WinDbg, most details are exactly the same, for all the 0x0000008e and 0x0000007e bug checks respectively: 0x0000008e Exception address: 0x808bc9e3 Trap frame: [varies] FAILURE_BUCKET_ID: 0x8E_nt!HvpGetCellMapped+97 Probably Caused by (IMAGE_NAME): ntkrpamp.exe 0x0000007e Exception address: 0x808369b6 Exception record address: 0xf70d3be0 Context record address: 0xf70d38dc FAILURE_BUCKET_ID: 0x7E_nt!MmPurgeSection+14 Probably Caused by: memory_corruption About 30% of the crashes happens between 17:00 and 19:00, which leads me to believe this tend to happen more often during logoffs. But then again, only ~15% occurs between 15:00 and 17:00.

• networking through openstack installed on vm

  - by Mandar Katdare

  I am trying to set up a test installation of Openstack on a Ubuntu 12.04 VM running on a ESXi server. So far I have been able to launch the VMs on the ESXi, however am unable to assign IP addresses to them. As the VM with the Openstack installation has a single public IP, I wish to assign IPs to the VMs create through Openstack so that they can directly interact with the public network itself without having a separate private network. So I feel that bridging would not be the correct option here. But am unable to find the correct documents to go ahead with such an install. My ifconfig looks as follows: eth0 Link encap:Ethernet HWaddr 00:0c:29:6f:8a:d7 inet addr:192.168.4.167 Bcast:192.168.4.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe6f:8ad7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:391640 errors:33 dropped:98 overruns:0 frame:0 TX packets:545044 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:40303931 (40.3 MB) TX bytes:763127348 (763.1 MB) Interrupt:18 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:146127 errors:0 dropped:0 overruns:0 frame:0 TX packets:146127 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:799815763 (799.8 MB) TX bytes:799815763 (799.8 MB) virbr0 Link encap:Ethernet HWaddr 8a:80:33:32:63:a0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) The eth0 is the adapter that I intend to use for all communication.

• Firefox 3.5.6 causes entire computer to freeze

  - by Anthony Aziz

  Here's the situation: Environment: Just installed a fresh copy of Win7 Pro 32-bit to NTFS partition on 750GB SATA drive Hardware: E8400 3GHz ASUS P5QL Pro 4GB DDR2 1066 RAM EVGA 9800 GTX+ Plenty of cooling, no problems with hardware before Data is stored on a separate partition, including My Documents No security software is yet installed No extensions installed yet Problem: While using Firefox, sometimes the entire computer will freeze/hang. I get no mouse or keyboard input, can't CTRL+ALT+DEL, no "not responding" indication, just a static image on my display. My drivers are all up to date as far as I'm aware (I just installed this copy of Windows last week). I first noticed this when trying to install Xmarks. I went to the Xmarks site and tried to install and it would freeze. I managed to get it installed (Safe mode and the Mozilla addon site worked), but when I go to configure it (log in, etc), the computer freezes. I don't think it's a matter of usage time or memory issues, because while testing, I browsed wallpaper galleries for about 30 minutes, sometimes as many as 12-15 tabs open at a time, without issue. Sometimes I won't even try to install Xmarks at it will hang. I can install (some) other extensions, the only one I've tried is download status bar (which works). What I've done to try to fix: Restarted (duh) Windows safe mode Completely remove Firefox and install it to a new directory, according to Mozilla's KB (I haven't tried the profile manager, though I assume this does the same thing, except perhaps more thoroughly) Some BIOS changes, including Power options, disabling oveclocking (it was a modest overclock on the CPU, which has run Win7 beta and RC for almost a year now) Memtest Used another Windows user profile, same tragic results I'm STUCK now, with no idea what to do. I'm using Chrome as my main browser at the moment, but that's not something I want to be stuck with. I like Firefox and want to use it. I'm going to try creating a new profile first. One thing I did notice: I started leaving task manager and performance monitor open when anticipating (but dreading) a freeze. firefox.exe had low CPU and low memory, but it looked like overall disk usage was seeing some spikes on the small graph Performance Monitor gives you. I saw on one blog post a fellow using XP moved his Local Settings directory from a separate drive to his main drive, and that solved it, but I don't think my AppData directory is on my D: drive, and that's on the same physical device anyways. Still, something that might be worth trying. I'd extremely appreciate any help. Thanks very much. I really don't want to reinstall Windows from scratch again :( Anthony Aziz

• Excel 2007 VBA macros don't work in Parallels

  - by MindModel

  I've got a complex Excel spreadsheet I need to use at work. My colleagues use the spreadsheet on Windows PC's, with no special configuration required. I want to run it on a MacBook Pro running Snow Leopard. The spreadsheet contains VBA macros which connect to external Oracle db's over the Internet. If I understand correctly, Excel on the Mac doesn't run VBA macros, so I have to use Parallels. I installed Parallels on the Mac and it's running correctly, as far as I can tell. I installed Excel 2007 under Parallels. I can open the Excel spreadsheet in Parallels and click buttons in the spreadsheet to run macros, but the macros fail with compiler errors. I don't have the password to the source code for the VBA macros, and if possible, I don't want to dig in to the code at that level. I know that there are quite a few things that could go wrong, and examining the VBA code might help, but I'm hoping to solve the problem without going down that road. The spreadsheet runs without any special configuration on Windows, so I'm wondering if anyone out there knows of any limitations of Excel VBA macros under Parallels, or anything else I could do to get this spreadsheet working. It's the only thing that's keeping me from using this MacBook Pro at work. Here is the error message: Compile error in hidden module: clsXXXXx0020Toolx0020Ser. This error commonly occurs when code is incompatible with the version, platform, or architecture of this application. Click Help for more info. Compile error in hidden module: A protected module contains a compilation error. Because the error is in a protected module it cannot be displayed. This error commonly occurs when code is incompatible with the version or architecture of this application (for example, code in a document targets 32-bit Microsoft Office applications but it is attempting to run on 64-bit Office). This error has the following cause and solution: Cause of the error: The error is raised when a compilation error exists in the VBA code inside a protected (hidden) module. The specific compilation error is not exposed because the module is protected. Possible solutions: If you have access to the VBA code in the document or project, unprotect the module, and then run the code again to view the specific error. If you do not have access to the VBA code in the document, then contact the document author to have the code in the hidden module updated.

• Getting macro keys from a razer blackwidow to work on linux

  - by Journeyman Geek

  I picked up a razer blackwidow ultimate that has additional keys meant for macros that are set using a tool that's installed on windows. I'm assuming that these arn't some fancypants joojoo keys and should emit scancodes like any other keys. Firstly is there a standard way to check these scancodes in linux? Secondly how do i set these keys to do things in command line and x based linux setups? My current linux install is xubuntu 10.10, but i'll be switching to kubuntu once i have a few things fixed up. Ideally the answer should be generic and system-wide Things i have tried so far: showkeys from the built in kbd package (in a seperate vt) - macro keys not detected xev - macro keys not detected lsusb and evdev output this ahk script's output suggests the M keys are not outputting standard scancodes Things i need to try snoopy pro + reverse engineering (oh dear) Wireshark - preliminary futzing around seems to indicate no scancodes emitted when what i seem to think is the keyboard is monitored and keys pressed. Might indicate additional keys are a seperate device or need to be initialised somehow. Need to cross reference that with lsusb output from linux, in 3 scenarios - standalone, passed through to a windows VM without the drivers installed, and the same with. LSUSB only detects one device on a standalone linux install It might be useful to check if the mice use the same razer synapse driver , since that means some variation of razercfg might work (not detected. only seems to work for mice) Things i have Have worked out: In a windows system with the driver, the keyboard is seen as a keyboard and a pointing device. And said pointing device uses, in addition to your bog standard mouse drivers.. a driver for something called a razer synapse. Mouse driver seen in linux under evdev and lsusb as well Single Device under OS X apparently, though i have yet to try lsusb equivilent on that Keyboard goes into pulsing backlight mode in OS X upon initialisation with the driver. This should probably indicate that there's some initialisation sequence sent to the keyboard on activation. They are, in fact, fancypants joojoo keys. Extending this question a little I have access to a windows system so if i need to use any tools on that to help answer the question, its fine. I can also try it on systems with and without the config utility. The expected end result is still to make those keys usable on linux however. I also realise this is a very specific family of hardware. I would be willing to test anything that makes sense on a linux system if i have detailed instructions - this should open up the question to people who have linux skills, but no access to this keyboard The minimum end result i require I need these keys detected, and usable in any fashion on any of the current graphical mainstream ubuntu varients

• Supervisor sentry-web exit status 1

  - by rockingskier

  I'm having problems getting Sentry (https://www.getsentry.com - not enough rep for a link) running as a service using supervisor. I can run Sentry in the command line and view it correctly in the browser but when it comes to supervisor I am completely in the dark. I shall try and give all the details I can Initial user warning By no means a server admin, just playing/learning in VirtualBox. Literally only just discovered supervisor from reading the Sentry documentation so I may well be making some obvious mistakes here. The setup: Ubuntu server 11.10 (fresh install, VirtualBox) virtualenv with Sentry and its dependencies. supervisor Instructions followed Supervisor with vanilla ini file Sentry/supervisor instructions My supervisor ini (Sentry section) [program:sentry-web] directory=/root/.virtualenvs/sentry/ command= start http /root/.virtualenvs/sentry/bin/sentry autostart=true autorestart=true redirect_stderr=true OK so here we go: When I run supervisord -n I get the following messages rather than a nice web interface to play with. 2012-04-12 23:48:09,024 CRIT Supervisor running as root (no user in config file) 2012-04-12 23:48:09,097 INFO RPC interface 'supervisor' initialized 2012-04-12 23:48:09,099 CRIT Server 'unix_http_server' running without any HTTP authentication checking 2012-04-12 23:48:09,100 INFO supervisord started with pid 17813 2012-04-12 23:48:10,126 INFO spawned: 'sentry-web' with pid 17816 2012-04-12 23:48:10,169 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:11,199 INFO spawned: 'sentry-web' with pid 17817 2012-04-12 23:48:11,238 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:13,269 INFO spawned: 'sentry-web' with pid 17818 2012-04-12 23:48:13,309 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:16,343 INFO spawned: 'sentry-web' with pid 17819 2012-04-12 23:48:16,389 INFO exited: sentry-web (exit status 1; not expected) 2012-04-12 23:48:17,394 INFO gave up: sentry-web entered FATAL state, too many start retries too quickly CRIT Supervisor running as root (no user in config file) suggests a big problem, probably shouldn't be running this as root? CRIT Server 'unix_http_server' running without any HTTP authentication checking Surely authentication is optional? INFO exited: sentry-web (exit status 1; not expected) *sad face* here. Google hasn't been much help yet. Anyway, that is it as far as I know. If anyone can help me that would be greatly appreciated. Thanks in advance.

• Linux boot on a raid1 software raid ?

  - by azera

  Hello I am trying to convert my single disk boot to a raid1 boot So far here is what i have: I sucessfully create the raid 1 as degraded with the new drive alone, I copied all the data on it I can mount that raid 1, see its files etc I already have a raid5 that is working on the same box (although not booting on it) I have installed grub on both drive When grub boot, it loads the kernel alright, but during the kernel boot it fails to load the "root block device" The kernel tells me : 1 - detected that root device is an md device 2 - determining root devices 3 - mounting root 4 - mounting /dev/md125 on /newroot failed: input/output error. Please enter another root device: ... At this point, if I enter /dev/sda3 (my "old" root device that isn't converted to raid yet) everything boots fine without the root. The /dev/md125 device is indeed created but it seems to be created after the error happens, as in it creates it after loading the device, when mdadm is loaded. Somehow it looks like it can't/doesn't load the raid array before it needs to mount it, and I don't know how I can solve that.

• Why is Excel 2010/2013 taking 10 seconds open any file?

  - by jbkly

  I have a fast Windows 7 PC with two SSDs and 16GB of RAM, so I'm used to programs loading very fast. But recently, for no reason I can figure out, Excel has started taking way too long to open Excel files (of any size--even blank files). This is occurring with Excel 2010 and with Excel 2013 after I upgraded, hoping to solve the problem. Here a couple scenarios: If I start Excel directly, it opens almost instantly. No problem there. If I start Excel directly, and then open any Excel file (.xls or .xlsx), it loads almost instantly. Still no problem BUT if I attempt to open any Excel file directly, with Excel not running, it consistently takes 10-11 seconds for Excel to start. I get no error messages, just a spinning cursor for 10-11 seconds, and then the file opens. During the delay while Excel is trying to start, I'm not really seeing any discernible spike in CPU or memory usage, other than explorer.exe. This problem is only occurring with Excel, not Word or any other program I'm aware of. I've searched around quite a bit on this question and found various others who have experienced it, but the solutions that worked for them are not working for me. For a few people it was a problem with scanning network drives, but my problem is purely with local files; I have no network drives, and the problem persists even with all network connections disabled. Some people suggested worksheets with corrupted formulas or links, but I'm experiencing this with ANY Excel file: even blank worksheets. Others thought it was a problem with add-ins, but I have all Excel add-ins disabled (as far as I can tell). One person solved it by disabling a "clipboard manager" process that was running in the background, but I don't have that. I've disabled as many startup and background processes as I can, but the problem persists. I've run malware scans, disk cleanup, CCleaner, and installed Excel 2013. I've deleted temporary files, enabled SuperFetch, and edited registry keys. Still can't get rid of the problem. Any ideas? My system details: Windows 7 Professional SP1 64-bit, Excel 2013 32-bit, 16GB RAM, all programs installed on SSD.

• Monitoring slow nginx/unicorn requests

  - by injekt

  I'm currently using Nginx to proxy requests to a Unicorn server running a Sinatra application. The application only has a couple of routes defined, those of which make fairly simple (non costly) queries to a PostgreSQL database, and finally return data in JSON format, these services are being monitored by God. I'm currently experiencing extremely slow response times from this application server. I have another two Unicorn servers being proxied via Nginx, and these are responding perfectly fine, so I think I can rule out any wrong doing from Nginx. Here is my God configuration: # God configuration APP_ROOT = File.expand_path '../', File.dirname(__FILE__) God.watch do |w| w.name = "app_name" w.interval = 30.seconds # default w.start = "cd #{APP_ROOT} && unicorn -c #{APP_ROOT}/config/unicorn.rb -D" # -QUIT = graceful shutdown, waits for workers to finish their current request before finishing w.stop = "kill -QUIT `cat #{APP_ROOT}/tmp/unicorn.pid`" w.restart = "kill -USR2 `cat #{APP_ROOT}/tmp/unicorn.pid`" w.start_grace = 10.seconds w.restart_grace = 10.seconds w.pid_file = "#{APP_ROOT}/tmp/unicorn.pid" # User under which to run the process w.uid = 'web' w.gid = 'web' # Cleanup the pid file (this is needed for processes running as a daemon) w.behavior(:clean_pid_file) # Conditions under which to start the process w.start_if do |start| start.condition(:process_running) do |c| c.interval = 5.seconds c.running = false end end # Conditions under which to restart the process w.restart_if do |restart| restart.condition(:memory_usage) do |c| c.above = 150.megabytes c.times = [3, 5] # 3 out of 5 intervals end restart.condition(:cpu_usage) do |c| c.above = 50.percent c.times = 5 end end w.lifecycle do |on| on.condition(:flapping) do |c| c.to_state = [:start, :restart] c.times = 5 c.within = 5.minute c.transition = :unmonitored c.retry_in = 10.minutes c.retry_times = 5 c.retry_within = 2.hours end end end Here is my Unicorn configuration: # Unicorn configuration file APP_ROOT = File.expand_path '../', File.dirname(__FILE__) worker_processes 8 preload_app true pid "#{APP_ROOT}/tmp/unicorn.pid" listen 8001 stderr_path "#{APP_ROOT}/log/unicorn.stderr.log" stdout_path "#{APP_ROOT}/log/unicorn.stdout.log" before_fork do |server, worker| old_pid = "#{APP_ROOT}/tmp/unicorn.pid.oldbin" if File.exists?(old_pid) && server.pid != old_pid begin Process.kill("QUIT", File.read(old_pid).to_i) rescue Errno::ENOENT, Errno::ESRCH # someone else did our job for us end end end I have checked God status logs but it appears CPU and Memory Usage are never out of bounds. I also have something to kill high memory workers, which can be found on the GitHub blog page here. When running a tail -f on the Unicorn logs I see some requests, but they're far and few between, when I was at around 60-100 a second before this trouble seemed to have arrived. This log also shows workers being reaped and started as expected. So my question is, how would I go about debugging this? What are the next steps I should be taking? I'm extremely baffled that the server will sometimes respond quickly, but at others time it's very slow, for long periods of time (which may or may not be peak traffic times). Any advice is much appreciated.

• Configuring VLAN's on two HP procurve switches

  - by pan

  Trying to route a new ISP (Microwave link) from one of my out buildings to my computer room and hence my firewall. Old ISP came direct into firewall. In the outbuilding the Microwave modem connects with cat5 to HP Procurve 2524 switch. Because this ISP is coming through my internal network, I plan on using a new vlan called "airspeed" only for this ISP traffic. Up until now I've just been using the Default_vlan on both HP switches (4108 + 2524). So far I've been unable to ping from my laptop to the ISP modem both of which are on the new vlan 2 ("Airspeed"). No traffic needs to cross from vlan 2 to vlan 1 so I've left the ports as untagged. I've used the subnet provide from my ISP as the new vlan 2 subnet. Can anybody see what I'm doing wrong here? I've added the configuration of both switch below. Rough diagram: Microwave modem (Gateway IP 77.75.00.49) | HP 2524 switch (port 24) | HP 2524 switch fibre link | HP 4108GL switch fibre link | HP 4108GL switch (port D1) | Laptop configured with IP 77.75.00.50 (for testing but will be connected to firewall) And my 4108GL config: ; J4865A Configuration Editor; Created on release #G.07.21 hostname "HP ProCurve Switch 4108GL" cdp run module 1 type J4864A module 2 type J4862B module 3 type J4862B module 4 type J4862B ip default-gateway 128.1.146.50 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged A1-A3,B1-B24,C1-C24,D2-D24 ip address 128.1.146.203 255.255.0.0 no untagged D1 exit vlan 2 name "Airspeed" untagged D1 ip address 77.75.00.51 255.255.255.248 exit Finally my 2524 config: ; J4813A Configuration Editor; Created on release #F.04.08 hostname "HP ProCurve Switch 2524" cdp run ip default-gateway 0.0.0.0 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.51 "public" snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged 1-23,25-26 no untagged 24 ip address 128.1.146.204 255.255.0.0 exit vlan 2 name "Airspeed" untagged 24 ip address 77.75.00.51 255.255.255.248 exit no aaa port-access authenticator active

• Error codes 80070490 and 8024200D in Windows Update

  - by Sammy

  How do get past these stupid errors? The way I have set things up is that Windows Update tells me when there are new updates available and then I review them before installing them. Yesterday it told me that there were 11 new updates. So I reviewed them and I saw that about half of them were security updates for Vista x64 and .NET Framework 2.0 SP2, and half of them were just regular updates for Vista x64. I checked them all and hit the Install button. It seemed to work at first, updates were being downloaded and installed, but then at update 11 of 11 total it got stuck and gave me the two error codes you see in the title. Here are some screenshots to give you an idea of what it looks like. This is what it looks like when it presents the updates to me. This is how it looks like when the installation fails. I'm not sure if you're gonna see this very well but these are the updates it's trying to install. Update: This is on Windows Vista Ultimate 64-bit with integrated SP2, installed only two weeks ago on 2012-10-02. Aside from this, the install is working flawlessly. I have not done any major changes to the system like installing new devices or drivers. What I have tried so far: - I tried installing the System Update Readiness Tool (the correct one for Vista x64) from Microsoft. This did not solve the issue. Microsoft resource links: Solutions to 80070490 Windows Update error 80070490 System Update Readiness Tool fixes Windows Update errors in Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008 Solutions to 8024200D: Windows Update error 8024200d Essentially both solutions tell you to install the System Update Readiness Tool for your system. As I have done so and it didn't solve the problem the next step would be to try to repair Windows. Before I do that, is there anything else I can try? Microsoft automatic troubleshooter If I click the automatic troubleshooter link available on the solution web page above it directs me to download a file called windowsupdate.diagcab. But after download this file is not associated to any Windows program. Is this the so called Microsoft Fix It program? It doesn't have its icon, it's just blank file. Does it need to be associated? And to what Windows program?

• Can't connect to DeploymentShare$ from PC attempting to MDT, but can other PCs on the network

  - by Moman10

  I am in the process of setting up MDT and have run across a problem. MDT is installed on a Windows 2012 server, MDT version 6.2.5019.0. Using WDS as well. Active Directory domain, the server is up to date and on the network. I boot up the PC, it gets an address from DHCP, pulls down the LiteTouchPE_x64.wim image and goes into the MS Solution Accelerators screen, the Processing Bootstrap Settings box comes up and processes for a couple of seconds, then goes away, it sits there for another minute or so and then gives the error: A connection to the deployment share (\\Acme-MDT\DeploymentShare$) could not be made. Can not reach the DeployRoot. Possible Cause: Network Routing error or Network Configuration Error." I can then retry or cancel. I have seen this error online but so far nothing that helps fix it, but seems to be an issue with the FQDN. I verified that I am getting an IP address and that I can successfully ping the MDT server if I use the FQDN, but can not just by it's A record of Acme-MDT. I tried manually mapping the network share using net use and it works if I use the FQDN, but it fails with an error code 53, "Network path not found" if I just use the A record of Acme-MDT. Here is the net use command I'm using: net use * \\Acme-MDT\DeploymentShare$ /u:Domain\Administrator It gives the error System Error 53, Network path not found (and doesn't prompt for a password), but if I use the FQDN of \\Acme-MDT.domain.com\DeploymentShare$ it works fine to map the drive. I guess the problem is, when it tries to load the image, it is trying to start from \\Acme-MDT\DeploymentShare$ and I need it to start from \\Acme-MDT.domain.com\DeploymentShare$, but not sure how to get it to do that. I've put the fully qualified path in CustomSettings.ini and bootstrap, updated the deployment share, regenerated the boot image and replaced the boot wim in WDS. Or, if someone has an idea as to why it's acting this way and knows a way around it. The end result is what matters! :) I did verify in DNS that Acme-MDT is there, with the proper IP, and I can successfully use the net use command to map this drive from a couple other computers that are already on the network. I am assuming it has something to do with that computer not already being part of the domain, but I'm honestly at a loss as to how to fix it. Any ideas are appreciated, thanks in advance for your help!

• Automating the choice between JPEG and PNG with a script

  - by MHC

  Choosing the right format to save your images in is crucial for preserving image quality and reducing artifacts. Different formats follow different compression methods and come with their own set of advantages and disadvantages. JPG, for instance is suited for real life photographs that are rich in color gradients. The lossless PNG, on the other hand, is far superior when it comes to schematic figures: Picking the right format can be a chore when working with a large number of files. That's why I would love to find a way to automate it. A little bit of background on my particular use case: I am working on a number of handouts for a series of lectures at my unversity. The handouts are rich in figures, which I have to extract from PDF-formatted slides. Extracting these images gives me lossless PNGs, which are needlessly large at times. Converting these particular files to JPEG can reduce their size to up to less than 20% of their original file size, while maintaining the same quality. This is important as working with hundreds of large images in word processors is pretty crash-prone. Batch converting all extracted PNGs to JPEGs is not an option I am willing to follow, as many if not most images are better suited to be formatted as PNGs. Converting these would result in insignificant size reductions and sometimes even increases in filesize - that's at least what my test runs showed. What we can take from this is that file size after compression can serve as an indicator on what format is suited best for a particular image. It's not a particularly accurate predictor, but works well enough. So why not use it in form of a script: I included inotifywait because I would prefer for the script be executed automatically as soon as I drag an extracted image into a folder. This is a simpler version of the script that I've been using for the last couple of weeks: #!/bin/bash inotifywait -m --format "%w%f" --exclude '.jpg' -r -e create -e moved_to --fromfile '/home/MHC/.scripts/Workflow/Conversion/include_inotifywait' | while read file; do mogrify -format jpg -quality 92 "$file" done The advanced version of the script would have to be able to handle spaces in file names and directory names preserve the original file names flatten PNG images if an alpha value is set compare the file size between the temporary converted image and its original determine if the difference is greater than a given precentage act accordingly The actual conversion could be done with imagemagick tools: convert -quality 92 -flatten -background white file.png file.jpg Unfortunately, my bash skills aren't even close to advanced enough to convert the scheme above into an actual script, but I am sure many of you can. My reputation points on here are pretty low, but I will gladly award the most helpful answer with the highest bounty I can set. References: http://www.formortals.com/introducing-cnb-imageguide/, http://www.turnkeylinux.org/blog/png-vs-jpg Edit: Also see my comments below for some more information on why I think this script would be the best solution to the problem I am facing.

• OSX 10.6.6 SSH md5 break-in check

  - by Alex

  Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

• Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca

  - by Marlen T. B.

  I have recently (as of July 2012) bought a HP Pavilion dv6-6c40ca laptop. It came pre-installed with Windows 7 on an MBR. I installed Ubuntu 12.04 on it on a GPT partition in what I think is BIOS emulation mode. I made a BIOS-Grub partition so the install didn't fail. That is what it is for .. right? Now I want to upgrade to UEFI mode. How would I Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca. Or is it impossible? My laptop, despite its new age may not be UEFI 2.0+ capable. If it isn't how can I install a software UEFI (i.e. a DUET such as the one by tianocore). Or is this too impossible? A link to my laptop's specs is: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03137924&tmp_task=prodinfoCategory&cc=ca&dlc=en&lang=en&lc=en&product=5218530 My laptop should have a UEFI given this link from HP http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01442956#N218. And from the link I draw a quote: That means most notebooks distributed with Windows Vista, and all notebooks distributed with Windows 7, have the UEFI environment. My laptop had Windows 7 Home Premium pre-installed. OK. Following the comments so far -- NOTE: I am trying to do this on an external drive so I can see if it works. I have partitioned the drive using GParted as a GPT drive. Created a 200MB partition at the beginning of the drive with a FAT32 file system. Given the 200MB partition a label of "EFI". Set the boot flag on the 200MB partition. What should a do next to install Ubuntu 12.04? Given the link: https://help.ubuntu.com/community/UEFIBooting#Selecting_the_.28U.29EFI_Graphic_Protocol In my first read through (just to see if I will understand everything before I start) I get to step 2.3 Install GRUB2 in (U)EFI systems The first line is Boot into Linux (any live ISO) preferably in UEFI mode. Um .. how do you tell what mode your live CD is in?! And how do you change it if the mode is wrong?
