• hiera data source in using puppet syntax?

  - by Zoredache

  The documentation for hiera on docs.puppetlabs.com seems to give me the impression that I can use puppet syntax to describe my data. Or posssibly will be able to in the future. See: Coming soon. Is this functionality present in a release version of puppet, and just not documented, or is this still being developed? If this functionality is present, does anyone have examples of how to actually use this? The presence of the puppet_backend.rb file on my system gives which was part of the puppetmaster package makes me thing that this functionality is present, but just not documented. So I am trying to figure out how to actually use this.

• A minimal Linux distribution for my ASUS EEE PC

  - by Andrioid

  I recently bought myself a ASUS EEE 1000HE and I intend to use it for note-taking and light browsing at the University. The machine has a 10" screen so the interface needs to be very compact. I've already tried: EEEbuntu: Very nice driver support and out of the box experience. But I feel that it is too slow booting and the general experience is too heavy in my opinion. Moblin 2: Looks very cool, boots just fine but is way too unstable to use. Also find it annoying that I can't find hotkey documentation anywhere. Any Netbook OS recommendation welcome (although those specific to my model would be great). There is an entire jungle of distributions out there, so if you've been on a safari, please share your experience.

• Excel - Filling images using a reference image

  - by tjans

  I have a spreadsheet that I use to create baseball cards for a tabletop baseball game. There are about 20 cards on my sheet, and I'd like to add a spot where I can set the logo and have it reflect that logo in each card without having to update 20 different images each time I create cards for a new team (and thus, a new logo). Is there a way to automate this process similar to setting one cell equal to the value of another (=A4, for instance)? I think the images aren't part of a cell and they float on top of the sheet, but I had hoped there was a way either with a macro or other VBA function (or maybe something built-in) that would accomplish this.

• How does syslog-ng handles flush_lines(0) ?

  - by Luke404

  I wanted to make sure my syslog-ng was doing async logging. Reading through the documentation I see the flush_lines() option for file() destinations, if unspecified, will use the global default. Then I see that the global setting defaults to 0 but it doesn't explain what that means. Is it going to do synchronous logging when set to 0? is it going to buffer an unlimited number of lines (flushing just every flush_timeout() number of seconds)? is it going to bite me?

• How do you confirm network adapter is gigabit capable?

  - by StrandedPirate

  Upgrading my network to gigabit speeds and don't know how to determine if the NIC in one of the systems is capable of gigabit speed. The documentation from the manufacturer states this: Network adapter 10/100/1000 Ethernet LAN on system board However when I go to the properties of the NIC under Speed & Duplex my only options are: 10 Mb Full 10 Mb Half 100 Mb Full 100 Mb Half Auto Is there a command line I can run that will give me more detail about the NIC? Windows 7 x64 OS New Info: The new switch I just bought has a light to indicate 1000Mbps. I can tell from the light that this NIC is indeed negotiating at 1000Mbps but I'd still like to know how to determine this from the console in windows.

• Overlapping appointments in Outlook 2003

  - by iansinke

  I'm using Microsoft Outlook 2003 (Home and Student, if that makes any difference, which I doubt) as my calendar, and I have one minor gripe: it can't really handle appointments that don't begin and end right on the half-hour mark. For instance, if I have a class that ends at 9:22 AM and another class that begins at 9:27 AM, they will appear to overlap in the day view. Not a big deal, but it bugs me nonetheless. Anybody know of a hack or patch that will fix this issue? I've searched the Outlook documentation as well as Google to no avail.

• Full disk encryption on linux (ubuntu) w/o re-installing - possible?

  - by sa125

  Hi - I work at a company that takes security very seriously (like most). Our IT guy came in today to prepare us mentally to re-install our systems after he'll apply the new encryption policy (which will basically scrape our HD clean). For our team this means about a week of re-configuring, installing, and tweaking our desktops until we are back to work capacity - anyone who has to re-install a development machine probably knows what I'm talking about. So, I guess my question is if there's any way to perform full disk encryption on a linux (ubuntu = 9.04) system without having to re-install EVERYTHING [sigh]. IT guy said there isn't any - please prove him wrong. thanks :)

• backing up a virtual machine

  - by ErocM

  I inquired with the support of justcloud.com telling them that I have a vmware vm that I was wondering if it could be backed up while in use. I can back up the vm once it is shut down but I was wondering if their "shadow copy" would back it up while running. This was their response: Thank you for your email. I am really very sorry but virtual machines can't be backed up for a simple reason that they are virtual, they have virtual memory, not physical memory. Please let me know if there is anything else I can help with. Kind Regards, Barry James User Experience Team www.justcloud.com These are physical files so I wasn't sure I even understood the response. Am I wrong in thinking that a vm can be backed up while in use? Does this response even make sense? I need a cheap alternative to backing up the vm off the server in case it goes down. Any suggestions?

• Change Command Prompt width from the Command Line

  - by Starkers

  Don't really know what more I can say really. That window captured below will simply not get any larger. Are there some settings somewhere that will allow me to resize it? See, this limited window thing has left me in a bit of a pickle. Basically I've created an application with a command line GUI (With Ruby's Curses Library), and while everything works beautifully on OSX and Ubuntu Terminals, with Command Prompt, if the Curses Windows are larger than the Command Prompt window as shown below, the whole application crashes with a 'window already closed' error. So, is there a setting that allows users to resize their Command Prompt window, something that I'll have to put in the documentation. Here's what the holy grail answer would, be though: Is there a way to do this from the command line? Could my application detect if the Command Prompt it's running on is of fixed width, and actually programatically run the command to allow the Command Prompt window to be enlarged? Or at least give the user a helpful error message?

• How to avoid tilde ~ in Bash prompt?

  - by Jirka

  Hello! I have set my prompt in bash in a such way that I can use it directly in scp command: My current PS1 string: PS1="\h:\w\n$" And the prompt looks like this: lnx-hladky:/tmp/plugtmp $ What I don't like at all is the fact that $HOME directory is displayed as tilde. Can this be avoided? It's causing problems when switching between different users. Example: lnx-hladky:~/DOC $ Documentation says: \w : the current working directory, with $HOME abbreviated with a tilde \W: the basename of the current working directory, with $HOME abbreviated with a tilde Is there any possibility to avoid $HOME being abbreviated with a tilde? I have found one way around but I feel like it's overcomplicated: PROMPT_COMMAND='echo -ne "\e[4;35m$(date +%T)\e[24m$(whoami)@$(hostname):$(pwd)\e[m\n"' PS1=$ Can anyone propose a better solution? I have a feeling it's not quite OK to run so many commands just to get prompt. (date,whoami,hostname,pwd). Thanks a lot! Jirka

• Word 2013: Get the page number for the previous page

  - by Mike Anthony

  I'm trying to accomplish something very simple in Word 2013, but the feature does not seem to be available, nor can I work it out with field codes. I simply want to include, on multiple pages, "continued from page n". In terms of field codes, I have tried this: { = PAGE - 1 \* MERGEFORMAT } It just tells me that PAGE is not a defined bookmark. Is there any way that this can be done? Edit: Per documentation I found somewhere, I also tried this - but with no luck: { = { PAGE } - 1 } This just threw Syntax Error, { back, which leads me to assume that it's incompatible with newer versions of Word.

• Monitoring IIS with SNMP

  - by Shtong

  Hello, I'm trying to monitor IIS using the Windows integrated SNMP service (for versions 2000, 2003 ans 2008 of Windows Server, but i'm doing my experiments on a 2008 R2 box). So far I was able to install the SNMP service, and query mib-2 values without problems. Now, I'm having trouble to monitor IIS informations, as the SNMP service does not seem to know about the .iso.org.dod.internet.private.enterprises.microsoft.software.internetServer OIDs. Walking the entire SNMP tree only gets the mib-2 stuff as well as the names of some services, but that's it. I did't find anything interesting in the service configuration panel. So how do I configure this service to get IIS information, or other WMI data for that matter (I installed the SNMP WMI Provider) ? I can't find any documentation about that !

• How to turn on SMTP relaying? Getting error: "SMTP Error: The following recipients failed [address]"

  - by Susan

  Attempting to configure some software on our server to send email via SMTP. When testing it, get this SMTP Error: SMTP Error: The following recipients failed [address]" Based on my research and a reply from the software's support team this error usually occurs because relaying is not allowed on the SMTP server from the IP address of the web server. The solution is to "Go to the configuration of your SMTP server and turn relaying on for your IP address" My question is -- how do I do this? Is this done from WHM? cPanel?

• Get cryptic error when trying to create a snapshot of any of my VMs

  - by Zolt

  I'm using Oracle VM VirtualBox. I have 6 VMs that I've imported. When I click on an individual VM, and then click the camera image (or Ctrl+Shift+S) to take a snapshot, the snapshot process fails and VirtualBox gives the following error: Failed to create a snapshot of the virtual machine vmName. Details: Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) This happens not only for one of my VMs, but all of them, if I try to take a snapshot of each one separately, one at a time. My computer is a Windows 7 machine. I have 200 GB free on my hard drive, and I see no reason why the error should occur. I can import VMs, run them, and clone then without any problems. Can anyone tell me what to do to fix the issue?

• Trying to understand why VLANs need to be created on intermediate switches

  - by Jon Reeves

  I'm currently studying for the Cisco switching exam and having trouble understanding exactly how 802.1q tagging works. Given three daisy chained switches (A,B, and C) with trunk ports between them and VLAN 101 defined on both end switches (A and C), I'm not sure why the VLAN also needs to be defined on the middle one (B)? Note that I am not disputing that it does need to be configured, I'm just trying to understand why exactly. As I understand it, traffic from VLAN 101 on switch A will be tagged as it goes through the trunk to switch B. According to the documentation I have read, trunks will pass all VLANs by default, and the .1q tag is only removed when the frame leaves through an access port on the relevant VLAN. From this I would expect switch B to simply forward the tagged frame unchanged through the trunk to switch C. Can anyone shed some light on how switch B processes this frame and why it does not get forwarded through the other trunk ?

• Mac OSX Server: svn via ssh command line and encrypted passwords.

  - by Ben Clayton

  Hi all. When I log into our mac mini server running OSX 10.6 via ssh and use svn I get the message: ATTENTION! Your password for authentication realm: can only be stored to disk unencrypted! You are advised to configure your system so that Subversion can store passwords encrypted, if possible. See the documentation for details. You can avoid future appearances of this warning by setting the value of the 'store-plaintext-passwords' option to either 'yes' or 'no' in '/Users/xxxxxxxx/.subversion/servers'. I dont' want to store the password unencrypted though. I've found some details on how to use GNOME keychain in linux to sort this, but nothing on how to use macosx's keychain. Anyone got any ideas? Thanks a lot!

• How to reliably take Java Heap Dumps?

  - by karlcyr

  My team is running into difficulties when trying to take good heap dumps triggered by OutOfMemoryErrors. For specific reasons we are currently taking the dumps with jmap called from a bash script instead of using the HeapDumpOnOutOfMemoryError flag. We're using a 64-bit 1.6 JVM with a heap size around 3 GB. Our heap dumps fail 90% of the time (guesstimate). Is there anything we can do to improve our odds of getting a clean heap dump we can use to troubleshoot memory problems? I have read that jmap had major issues in Java 1.4 but that those issues should be mostly addressed now.

• CloudFormation - How to start a Windows Service with cfn-init

  - by Edwin

  I'm creating a CloudFormation Stack that will install and start a service on a Windows Instance. I've figured out how to install the service, but how do I start the service using cfn-init? The examples seem to all use linux, as there is a reference to "sysvinit" How do I structure AWS::CloudFormation::Init so that cfn-init will start windows services after installing them? Do I leave in the sysvinit, replace it with something else, take it out? ps: I'm referring to how to start services by providing information to AWS::CloudFormation::Init.services. Also, It would be nice to know how "packages" work for windows. AWS's announcemnet says that packages are supported on Windows but there is no Windows specific documentation

• Dell SC1435 always requires F1 at boot

  - by David Mackintosh

  I have a Dell PowerEdge SC1435 that has come back after doing duty at a partner site. I am trying to configure it for local use. The only problem I have with it is that every time it boots it always requres a manual F1 press after the POST sequence. The last thing it does is give me the opportunity to configure the BMC, and then it says: Press F1 to continue or press F2 for Setup It will wait there forever (well, at least an hour). Pressing F1 starts the OS booting. I can't see the setting in the BIOS which controls this and I can't find it in the documentation. What am I missing?

• Directly editing IIS 7 applicationHost.config configuration file

  - by lunadesign

  I know that IIS 7+ now uses XML config files instead of the metabase. I also know that if I edit a web.config file for a given site, IIS automagically detects the changes and implements any corresponding config changes. However, does this also apply to the server-level applicationHost.config settings file? (Its usually located in C:\windows\system32\inetsrv\config.) Specifically, is it safe to carefully edit this file instead of using IIS Manager or the appcmd command line utility? I couldn't find anything in the documentation that said it was okay or not okay to do this. I'm curious because I have to change the bindings for numerous sites from one IP to another. It would be much faster to simply do a global search and replace for the IP address in the config file instead of manually editing a few dozen sites in the GUI.

• Load balance between two virtual directories on a single machine running IIS6

  - by Emil Lerch

  I'm trying to simulate a production environment using a single VM. The production environment will have 3 servers behind a load balancer with sticky sessions. Production will be using IIS6. For development, I have no need to distribute load, but I want to make sure the team does not write code that relies on a single-server module. I have been hoping to set up two virtual directories and find some isapi filter to perform some rudimentary software load balancing, but I've been unable to locate anything suitable. isapi_rewrite comes close but there's no ability for a random rewrite. I don't even need sticky sessions since the application does not (in theory) rely on them. Is there something easy/free to do this, or am I stuck with multiple VMs and a NLB setup (which seems like total overkill)?

• Newbie one: Virtual Networks - Hyper-V - Remote Destktop - Only one phisical NIC

  - by josecortesp

  Hello everyone, I'll try to explain my situation and I'll apreciate any help: I have a phisical server (quad core, 4Gb ram, 1TB raid 10, etc) with Win Server 2008 R2 enterprise, running IIS, Printing, etc... Also, I want to set up 2 virtual Servers with 2008 R2 standart one with SQL Server and the other with Team Foundation. What i need is: Being able to access from inside the private phisical network, to Remote Desktops on each of the Virtual and the phisical Servers Had Access from the outside, using a router and port Forwarding, to the TFS server and the IIS server (one is virtualized, the other is phisical) This is it, but note that I only have one Phisical Nic. How do I configure this to work. When i set up the hyper-v role, on the wizard something like it showed up but I don't remmember what i choose, and right now, I cannot access none of the servers from remote desktop, not even from the phisical private network. Can anybody point me, what can i do? Thanks in advance (sorry 4 my english, i'm a spanish talker and my english isn't that good)

• Can I use PLink and Pageant with Cygwin's ssh?

  - by Jerph

  I'm now using msysgit because of the GUI tools, which use Putty's Pageant and PLink utilities, but I use Cygwin as a general SSH terminal. I had been using ssh-agent on Cygwin, but that means I have to enter my SSH key passphrases for both SSH key managers. Is it possible to configure all my Unix-port tools (msys, git, cygwin, Ruby Net:SSH, etc.) to use PLink/Pageant instead of ssh-agent? It seems that's the kind of thing PLink was made for, but I can't find documentation on how.

• MongoDB ReplicaSet Elections when some nodes are down

  - by SecondThought

  I'm trying to get into ReplicaSet concept, and found something weird in mongoDB Documentation: For a node to be elected primary, it must receive a majority of votes. This is a majority of all votes in the set: if you have a 5-member set and 4 members are down, a majority of the set is still 3 members (floor(5/2)+1). Each member of the set receives a single vote and knows the total number of available votes. If no node can reach a majority, then no primary can be elected and no data can be written to that replica set (although reads to secondaries are still possible). (taken from here) So, If I got that right, in the 5-member case mentioned there the one node that's still standing WILL NOT be chosen as primary and the whole set will not get any writes? and that's even if this single node was the last primary before the elections? If it's true there can be many less-radical cases which will end up with a degenerated set. How can we avoid this?

• 'Unsaved Theme' is not appearing when I make a change to a theme in Windows 7

  - by Bernard

  According to personal experience and Microsoft documentation, when an aspect of a theme (wallpaper, border colour, etc) is changed in the 'Personalization' screen of Windows 7, a theme called Unsaved Theme is supposed to be created/exist under the 'My Themes' heading. However, my 'My Themes' section is always empty, and if I change the background by clicking on the Background link at the bottom of the Personalization page, the background changes, but it still shows 'Harmony' as the selected background, and no 'Unsaved Theme' is created. I have no idea how long this has been happening, but I would like to create some themes, but it never acknowledges my changes as it is supposed to.
