• How do I convert this filetype to pdf?

  - by Gnoupi

  This question is coming back often, and the general answers are very often the same. In an objective to concentrate useful information in one place, here is a community wiki about it. How can I convert this filetype to pdf? This question will have two kind of answers: The generic case, which works for most filetypes. The specific cases, which should be one answer per filetype. Restricting the OS field to Windows, as most of these questions are about this OS. This may change eventually. As it is community wiki, feel free to edit this question to improve it as well.

• Load Balancer recommendations

  - by delerious010

  I provide hosting service for about 250 clients to date, and this is increasing on a monthly basis. For each client, I have 2 "services" configured for L4 balancing / persistence .. one on port 80, another for port 443 which redirects to another internal port as well as 4 servers per service. This equates to a total of 500 "services" and 2000 "servers". I'm currently running with a couple CoyotePoint load balancers, and have had a look at some Barracudas but so far I'm really not impressed by those. Could anyone recommend some good load balancers which would be able to support this sort of load ? And which offer a good API, or shell access to automate management.

• Could a too low voltage during long periods damage my computer fan?

  - by Sopalajo de Arrierez

  Computer fans use to run at 12Volt, but most as for today they allow 9Volt or even less to slow down the fan speed (RPM, Revolutions Per Minute). In cases of too low voltage, the fan stops, but I can see it "trying to start again". For example: my Tacens 9dB fan stops at about 10 Volts, but to start it again, 10.5Volt is not enough, and the engine tries to move the fan (I can see a small movement as an "attempt" to move) each 1-5 seconds, but it does not succees, so the fan keeps at 0 RPM. Maybe that "attempt" to move could damage the internal engine of the fan when it last for hours or days?

• Can't install Parallels Tools on Debian 7.2.0

  - by jfm429

  (Parallels Desktop 9, latest version) As per instructions, I switch to root: $ su - root $ whoami root $ echo $EUID 0 and then execute the installer: $ cd /media/cdrom0 $ ./install and I get this error: sudo: unable to execute ./install: Permission denied What? I'm root! What's with this? I double check to make sure the execute bit is set: $ ls -lA | grep install$ -r-xr-xr-x 1 root root 17284 Oct 25 09:22 install Yep. People online are saying that you need to drag the install script to the terminal after typing sudo. So I do that, and this command is what's formed: $ sudo '/media/cdrom0/install' sudo: unable to execute /media/cdrom0/install: Permission denied What's the solution here?

• how to configure my internal dns to resolve external resources

  - by Ralph Shillington

  I have an internal DNS as part of my AD setup. I have an hosted DNS for public resources (which are typically at some data centre somewhere) Occasionally while on our internal network I need to get to a public resource --- for example www.ourcompany.com since there isn't a www record in our internal DNS I cant get the name resolved. How do I configure my DNS to forward names it doesn't recognise to the public DNS. Update: As per the comment yes I have a "split-horizon" dns (which seemed like a good idea at the time) This AD setup is less than 24 hours old, and can be redone if need be -- (although I would rather not)

• shibboleth: tomcat failing to start IdP listener

  - by HorusKol

  I have installed a Shibboleth Identity Provider as per http://www.edugate.ie/workshop-guides/shibboleth-2-identity-provider-installation-linux-debian-or-ubuntu However, testing only gave me a 404 from Tomcat, and when I checked the Tomcat logs, I saw that the IdP listener was not starting: 10/01/2011 11:25:31 AM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor idp.xml 10/01/2011 11:25:32 AM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart 10/01/2011 11:25:32 AM org.apache.catalina.core.StandardContext start SEVERE: Context [/idp] startup failed due to previous errors The IdP descriptor file has the following context: <Context docBase="/opt/shibboleth-idp/war/idp.war" privileged="true" antiResourceLocking="false" antiJARLocking="false" unpackWAR="true" /> I have confirmed that the WAR file is located as the Context above specifies - as I have found similar issues from other people where the WAR file was not found. However, the logs posted by those people indicate that the descriptor file was correctly read by Tomcat and their problem was with the WAR file itself. I'm assuming this is some kind of syntax error with the idp.xml, but cannot determine what it might be. Also - setting the Tomcat logging level to FINEST does not provide any additional information in the logs for this error.

• Wrapping text in an opened file in vim

  - by TK

  I want to soft wrap text in Vim to 90 columns per line. I want soft wrap so that it doesn't affect actual text by adding line break characters. Here's is what I tried: // Opened a file with lots of text and ran the following: set wrap set tw=90 set linebreak Running the commands doesn't change anything about the view at all. It soft wraps at the end of the window. I have used "Soft Wrap" in TextMate by Command-Option-W to get the same effect, and want to know how to get it work on Vim.

• Importing email from other accounts in Gmail

  - by reyjavikvi

  I have a Gmail account that imports (via POP) messages from an old Hotmail account that people still send mail to. I normally read my mail with Thunderbird, not the web interface. The thing is that Gmail imports the mails once per hour (approx), and sometimes I want to know if right now there are messages in my old account. I could just go and hit the "import now" button, but whatever. Is there someplace in the settings where I can change it so the importing happens once each, say, 15 minutes? Alternatively, is it possible to make a script that will tell Gmail to import the messages at that moment, just like it would if I went to the Settings and clicked "Check if I have mail now". I've heard about libgmail for Python, but it doesn't seem like it can do that.

• how to create iso dvd image for use with mac/osx "Disk Utility"?

  - by adolf garlic

  This seemed way easier on my pc. I would just pop a blank dvd in the drive, it asked what I wanted to do with it, to which I would respond, "burn dvd with nero" (paraphrasing), then I would pick "new" and just drag and drop the folders in there. Mac appears to have "Disk Utility" which just requires that I 'choose an image' but then doesn't bother to detail - how to do this - what the options mean e.g. format "mac OS extended (journaled)" is that ever going to be readable on a non mac machine? I want to create an ISO standard dvd as per the 'default' you'd get on nero. All the stuff on the web points to doing things with 'terminal' (the whole point of buying a mac was to get away from command line jiggery pokery - I'm trying to burn some photos not land a friggin lunar module here!) Please, if you can just provide some simple instructions on what I need to achive this I'd be extremely grateful. Ta muchley in advance.

• Subversion multi checkout post-commit hook?

  - by FLX

  The title must sound strange but I'm trying to achieve the following: SVN repo location: /home/flx/svn/flxdev SVN repo "flxdev" structure: + Project1 ++ files + Project2 + Project3 + Project4 I'm trying to set up a post-commit hook that automatically checks out on the other end when I do a commit. The post-commit doc explicitly lists the following: # POST-COMMIT HOOK # # The post-commit hook is invoked after a commit. Subversion runs # this hook by invoking a program (script, executable, binary, etc.) # named 'post-commit' (for which this file is a template) with the # following ordered arguments: # # [1] REPOS-PATH (the path to this repository) # [2] REV (the number of the revision just committed) So I made the following command to test: REPOS="$1" REV="$2" echo "Updated project $REPOS to $REV" However when I edit files in Project1 for example, this outputs "Updated project /home/flx/svn/flxdev to 1016" I'd like this to be: "Updated project Project1 to 1016" Having this variable allows me to specify to do different actions per project post-commit. How can I specify the project parameter? Thanks! Dennis

• Forward Windows Events Logs to Rsyslog

  - by SamCulley

  Thanks for taking time to read this post. Basically I would like to forward Windows Events Logs from all my desktop clients to a linux box with rsyslog on. Rsyslog provide a Windows agent to do just that but its 40 euros per license and when you have x amount of machines that cost adds up. I was wondering if there is a FOSS alternative available I have tried searching the Google but haven't managed to find anything. Hopefully someone might already faced this same problem and are using an alternative that they could recommend. Again thanks for reading, Kind Regards Sam

• Stability, x86 Vs Sparc

  - by Jason T

  Our project are plan to migrate from Sparc to x86, and our HA requirement is 99.99%, previous on Sparc, we assume the hardware stability would like, hardware failure every 4 month or even one year, and also we have test data for our application, then we have requirement for each unplanned recovery (fail over) to achieve 99.99% (52.6 minutes unplanned downtime per year). But since we are going to use Intel x86, it seems the hardware stability is not so good as Sparc, but we don't have the detail data. So compare with Sparc, how about the stability of the Intel x86, should we assume we have more unplanned downtime? If so, how many, double? Where I can find some more detail of this two type of hardware?

• What is better to have more LUNs or more Storages

  - by skomak

  Hi, what is better to have - more LUNs or more Storages. Actually i have 1 storage ESXi per 1 LUN so there are about 15 LUNs and 15 storages. Now there is a kind of problem because the LUNs have different space allocated so if i remove 2 LUNs f.e. 1 2 3 4 [x] 6 [x] 8 9 (like that) i can't make 1 LUN from 5 and 7 pieces of free diskspace on IBM storage array. It's a first argument to not have a lot of LUNs. If i had to make only a few LUNs (about 3) and inside some Storage from ESXi would it be a better idea? For example for expanding storage capacity? i look for good solutions. Thanks in advance.

• Difference between multiple NS and NS having multiple A

  - by Jake

  I found this Can an NS Record Point To Multiple A Records?, but wonders what is the difference, if any. For example: mydomain.com. IN NS ns1.myhost.com. mydomain.com. IN NS ns2.myhost.com. ns1.myhost.com. IN A 111.222.333.1 ns2.myhost.com. IN A 111.222.333.2 versus mydomain.com. IN NS ns.myhost.com. ns.myhost.com. IN A 111.222.333.1 ns.myhost.com. IN A 111.222.333.2 EDIT: actually, come to think of it, it could be said the same for MX records. Any breaking differences? EDIT 2: then again, MX allow use of priority values so its a different case, in that one-ip-per-domain is more useful sometimes.

• How to set up Dell OMSA tools on Debian 6 (Squeeze) (PE2950)

  - by javano

  I assume I have set up them up incorrectly or am missing a library or dependency. When I log into the OMSA web interface I can't see anything Also, omreport tells me nothing; root@box:~# omreport storage controller No controllers found I assume these two will use the same source of information so what ever is wrong will fix them both. I set up OMSA as per these instructions. Also I have compiled MegaCLI (as this is a PowerEdge 2950 with a Perc 6/i controller) and I have used that to update the RAID firmware, so that works, but the Dell tools aren't. What have I missed during set up? root@kvm1:~# cat /etc/issue Debian GNU/Linux 6.0 \n \l root@kvm1:~# uname -a Linux kvm1.mivoice.cust.vostron.net 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux

• Creating an office network and monitoring all activity without a proxy

  - by Robert

  We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

• Modify HTML Content with Squid

  - by user38400

  We have setup our network as per the tutorial here: https://help.ubuntu.com/community/Upside-Down-TernetHowTo. Basically, we have a squid proxy that inverts images for pages that clients request. We're trying to modify the script so that we can edit the contents of the webpage before the webpage is sent to the client. We are not having any luck. I'm wondering if there is something different about .html files that makes this not possible. What is happening is that we do a wget on the URI that is requested, save it locally, modify it and then echo back the new URI. The page that the user gets is the unmodified page and not the one that we just changed.

• VirtualBox serial port, limit of two?

  - by Evan Carroll

  Using VirtualBox, Is there a limit of two serial ports per VM? I'm currently engaging in a task that requires more than two, but less than or equal to four ports. I'm at a loss of what to do to get COM3 and COM4 up? How do I do it if the Virtual Box GUI doesn't currently support more than two serial host devices? Can I configure them external to the GUI? Is there a hard-cap on two devices? And, if so, for the love of god, please entertain me with the reasoning? I know Windows and Linux don't impose such a limit, it would seem awkward to impose it in virtualization layer. This is for cheap dial-in project with proprietary Windows tools. I'm using a Quatech serial multiport adapter to provide the ports to multimodems.

• capistrano still asks for the 1st password even though I've set up an ssh key???

  - by Greg

  Hi, Background: I've setup an ssh key to avoid having to use passwords with capistrano per http://www.picky-ricky.com/2009/01/ssh-keys-with-capistrano.html. A basic ssh to my server does work fine without asking for passwords. I'm using "dreamhost.com" for hosting. Issue - When I run 'cap deploy' I still get asked for the 1st password (even through the previous 2nd and 3rd password requests are now automated). It is the capistrano command that start with "git clone - q ssh:....." for which the password is being requested. Question - Is there something I've missed? How can I get "cap deploy" totally passwordless? Some excerts from config/deploy.rb are: set :use_sudo, false ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "id_rsa")] default_run_options[:pty] = true thanks PS. The permissions on the server are: drwx------ 2 mylogin pg840652 4096 2010-02-22 15:56 .ssh -rw------- 1 mylogin pg840652 404 2010-02-22 15:45 authorized_keys

• Windows apps keep switching to accented text

  - by Josh Kelley

  Somehow I keep hitting a shortcut key (or something similar) that enables the input of accented text. Whenever this accented text mode is enabled, pressing ' doesn't respond immediately; instead, the ' key is remembered, so if I press a vowel after that, I get the vowel with an acute accent mark, and if I press any other key, I immediately get an apostrophe followed by the other key. I don't want this to happen. It's very annoying. How do I disable this mode? I only remember seeing this in Firefox 3.6.3 and Pidgin 2.6.6, so maybe it's a GTK feature. It apparently happens on a per-application basis, and restarting the application fixes it. I checked Windows 7's "Region and Language" control panel and didn't see anything relevant (although I'm not intimately familiar with all of those settings, so I may have overlooked something).

• Realtek HD Audio playing weird with certain video formats

  - by dyasny

  Hi, I have a Gigabyte motherboard with an onboard Realtek HD sound card. The card is working perfectly everywhere, except for a single video format, where the voice is distorted, sounds as if it's been passed through a metal tube. Been googling for this, but couldn't find an answer anywhere. The movie plays fine on other systems (got Linux everywhere else), but on this one (winXP-x64-sp2) it just doesn't. Here are some details: MPC: Type: KLCP WMV File Audio: 0x000a 22050Hz mono 20Kbps [Raw Audio 0] Video: Windows Media Video 9 400x300 29.97fps 227Kbps [Raw Video 1] VLC: Codec: wmas Sample rate: 22050 Bits per sample: 16 Bitrate: 20kb/s

• DFS-R (2008 and R2) 2 node server cluster, all file writes end in conflictAndDeleted

  - by Andrew Gauger

  Both servers in a 2 server cluster are reporting event 4412 20,000 times per day. If I sit in the conflictAndDetected folder I can observe files appearing and disappearing. Users report that their files saved by peers at the same location are overriding each other. The configuration began with a single server, then DFS-R was set up using the 2008 R2 wizard that set up the share on the second server. DFSN was set up independently. Windows users have drives mapped using domain based namespace (\domain.com\share). Mac users are pointed directly to the new server share created by DFS-R. It is PC users indicating most of the lost files, but there has been 2 reports by Mac users about files reverting.

• SBSMonitoring.mdf reached limit

  I have SBS 08 Standart. I have some Error in my Event Viewer with MSSQL$SBSMONITORING Event id 1105, 1827: Could not allocate space for object 'dbo.EventLog'.'PK_EventLog' in database 'SBSMonitoring' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database.
