• CentOS send mail with external SMTP server and without local daemons

  - by Vilx-

  I've got a little old server with CentOS 6.5 on it. The hardware is old and crappy, but enough for what it has to do. Which consists of SSH (+SFTP), Apache, PHP and MySQL. Still, I'm trying to cut away all that I can. One thing that it does not need to do is to be an SMTP server. There are no mailboxes on it and nobody will ever route mail through it. However I do want it to send me an email when something goes wrong. Also, the webpages will send emails from PHP. So that brings me to the question - can I set up the mail system in such a way that there isn't an expensive mailer daemon sitting in the background with queues and whatnotelse, but rather every email is directly and immediately delivered to an external SMTP server? And how do I go about it?

• Appropriate Network switch for small server cluster

  - by Chris Dutrow

  Need to build a small business server cluster for the purpose of crunching data. It will not host a web site that needs to be available 24/7. It does need to support servers that host Redis, a Cassandra database cluster, and a Python web server. Operating system will most likely be Centos 6.4 Other servers in the cluster should be able to communicate very fast with each other, especially the Redis server. This will probably require the use of internal IP addresses. We will need to use multi-data center replication to synchronize the Cassandra cluster with the one that we currently have hosted on the cloud Was looking into network switches and we are unsure of the appropriate specifications that we should be looking for. Does the switch need to be "managed" or can it be "unmanged"? Does the switch need to support IPv6 or just IPv4? Do we need an enterprise level Cisco switch, or can we go with something like a $200 DLink managed (or unmanaged) small business switch? Thanks so much!

• Segmentation Fault with mod_include

  - by Benedikt Eger

  Hi, I'm using a rather complex structure with multiple ssi-includes, set- and echo-commands. The first document writes a lot of set-commands, includes another document which then again includes a third document. On the last included document the variable values are printed using the echo-command. I noticed that with an increasing number of variables the probability for a segmentation fault to happen rises. Did anyone experience something similar? How do I go about debugging such a problem? I'm using IBM_HTTP_Server/2.0.47.1-PK65782 Apache/2.0.47

• Sendmail.mc: alias all incoming e-mails to one account

  - by Angus

  I need to alias all mail coming from another SMTP server to this one account "myinbox". The system in question is to receive all e-mail on the domain, if that's any help. http://william.shallum.net/random-notes/sendmailredirectallmailfordevelopment is a template for the beginning of a solution, but that routes everything (including outgoing and internal mail) to that one account, and trying to understand how these R rules work is making my head spin. I think the answer is in sendmail.mc rather than any Procmail configuration. So I think what I generally don't want the filter to do is: Interfere w/any outgoing e-mail Interfere w/any internal e-mail Sometimes some cron job causes "root" to mail to "root". I don't want these to go to myinbox. Cause infinite loops Who does? Bounce messages and any DSNs come to mind. I'm running Sendmail 8.13.1 and Procmail 3.22.

• What would happen if I did a "Boot to VHD" to a VHD that was configured to run under Hyper-V?

  - by tbone

  Microsoft has a Hyper-V based VM I'm interested in running, however, I don't have access to a Windows Server 2008 machine to try it on, only a Windows 7 Pro x64 machine (Windows 7 does not support Hyper-V). This is the VM in question: This download contains three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1) http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 I came across a somewhat relevant article from Scott Hanselman: Less Virtual, More Machine - Windows 7 and the magic of Boot to VHD: http://www.hanselman.com/blog/LessVirtualMoreMachineWindows7AndTheMagicOfBootToVHD.aspx I realize other options are to convert this VM to a VMWare compatible VM or some of the options to run it under VirtualBox. But instead of those routes, I'm wondering: What would happen if I tried to go the "Boot to VHD" route using this Hyper-V VHD? Is it possible that during the boot process, Windows would simply notice that hardware had changed and adjust accordingly, installing the appropriate drivers and continuing on without a hitch?

• Automatic switching between "digital output" (HDMI) and built-in speakers in Vista

  - by Laurence Gonsalves

  We occasionally connect my wife's laptop, which runs Vista, to our TV. Whenever we do this we have to manually switch the default audio output to "digital output" for the sound to go through the HDMI connection, and we also have to restart any apps that we want to send sound to the TV. We then have to perform a similar process when disconnecting. Is there any way to just have this be automatic? It seems absurd to have to do so much manual fiddling when a 40 year old transistor radio is "smart" enough to turn off the speakers and send sound to the headphones when headphones are plugged in. In case it helps, the name "RealTek" shows up in the sound card settings dialog.

• Powershell script to append an extension to a file, input from CSV

  - by Jeremy

  Hi All, All I need is to have an Excel list of file paths and use Powershell to append (not replace) the same extension on to each file. It should be very simple, right? The problem I'm seeing is that if I go input-csv -path myfile.csv | write-host I get the following output: @{FullName=C:\Users\jpalumbo\test\appendto.me} @{FullName=C:\Users\jpalumbo\test\append_list.csv} @{FullName=C:\Users\jpalumbo\test\leavemealone.txt} In other words it looks like it's outputting the CSV "formatting" as well. However if I just issue import-csv -path myfile.csv, the output is what I expect: FullName -------- C:\Users\jpalumbo\test\appendto.me C:\Users\jpalumbo\test\append_list.csv C:\Users\jpalumbo\test\leavemealone.txt Clearly there's no file called "@{FullName=C:\Users\jpalumbo\test\leavemealone.txt}" and a rename on that won't work, so I'm not sure how to best get this data out of the import-csv command, or whether to store it in an object, or what. Thanks!!

• Exchange 2010 install locks out high level accounts

  - by tearman

  Basically, when we installed Exchange 2010 alongside our Exchange 2003 server (we assume), this is what caused our problem. The Exchange 2010 server is not active, just running on the domain. What's actually going on is that user groups like Enterprise Admins are getting a single deny flag on Full Control over mailboxes currently residing on the Exchange 2003 server which is preventing any of us from making changes. It says these permissions are inherited from the Parent Object, but we have no idea which one that is. Any idea on how to go about fixing this?

• How can one convert a Word form to a PDF form while preserving fields?

  - by Ben Collins

  I have a Word source document which I'm using to create a PDF form. The first go-round, everything is fine because I can let Acrobat Pro auto-create all the fields. That feature is actually pretty awesome. However, after spending a bunch of time adjusting field sizes and alignments and formats and so on, I want to edit the source document, and now I'm faced with the prospect of doing all that over again. Isn't there some way to add the fields in the source document using the Developer ribbon and have those fields be preserved in the conversion to PDF? If not, what other ways are there to avoid this kind of redundant effort?

• Importing CSV files into Excel using a macro

  - by B-Ballerl

  I'm want to develop a macro where in my excel worksheet I type a date in a specific cell, and the macro will go into a folder containing text files. A database you could say. I want it to find the corresponding file name which is written as a date, put the data through a delimeter, and paste into the cells directly below where I orginally put the date. I'm very new with Macro's so if you must answer try to be a little more simple than you might usually be. Thanks In Advance if anyone can Help!! Update The folder will always be in the same place and the text files will all be formatted DD_MM_YYYY. And there cells below will always be empty Some Pictures to Make what I'm asking, easier to figure out. View the Image in a new tab for better res.

• Loading guest OS's (Windows) localhost through my host's (Mountain Lion) browsers

  - by Jonah Goldstein

  For work, I have to develop in Visual Studio, which I run via VMware's fusion 5. I really want to test via my mac's native browsers for a multitude of reasons. that is, view the IIs web stuffs that my windows VM should expose, in my mac's own native Firefox, Chrome... etc. if i could expose a pretty url, that would be even better, but i would certainly settle for an ugly IP :) I got a decent number of views but no response when I asked in VMware's own boards. Everyone seems to want to go the other direction (developing in sublimetext/textmate serving up through MAMP and exposing it to windows browsers to test) and there seems to be tried a true solutions for this. unfortunately (or fortunately depending on your preference) my startup is pretty entrenched in the visual studio development tools. I'm really hoping that someone knows the answer to this. Thanks :)

• Installing linux on a crippled machine via network boot?

  - by networkbooter

  I have a somewhat ancient Toshiba laptop (which can't boot from USB) that I want to install linux on (probably Ubuntu). I'm currently running Windows XP and Ubuntu via Wubi. I want to delete these OSs and replace with Ubuntu only. The laptop does have a network boot option. I'm wondering if the easiest way might be to setup a network boot server on my other computer (which runs Ubunutu) and boot the laptop from it. Could this allow me to install Linux on the laptop? I can't seem to find instructions on the 'net as to how to go about doing this.

• How to open Firefox's "organize bookmarks" from Vimperator?

  - by Igor Popov

  Before using Vimperator, I used Xmarks for organizing and synchronizing bookmarks between computers. Now I installed Vimperator and I can only bookmark a page from command mode with :bmark. How can I open Organize Bookmarks with Vimperator? Besides disabling Vimperator and choosing it from the menu what else can I do? Before, I had CTRL + SHIFT + b to open the organizer. Now, in Vimperator, this shortcut doesn't work anymore, even after temporarily disabling Vimperator with CTRL + z. EDIT After setting the main menu visible (with :set go+=m thanks to Hamish Downer), I saw the shortcut for opening the organize bookmarks dialog (CTRL + SHIFT + o). I recently switched to Ubuntu Linux and in this version of Firefox some keyboard shortcuts are different then in Windows (including the shortcut for opening organize bookmarks). Sorry for my ignorance.

• Disable "Send as XPS Attachment" Word 2007

  - by Tim Alexander

  Is there a way to disable this option either via Group Policy or via some form of registry hack? Normally I would go down the route of telling users not to send as XPS and send as something else but with our recent upgrade to 2007 lots of users are banding these files around. Unfortunately our version of Citrix does not play nicely with XPS documents and we end up having to log them out. Am told the fix for Citrix is not forthcoming so wondered if I could bury my head in the sand and disable the option all together. Regards Tim

• BIOS root kit? Or, how do I fresh install a clean BIOS?

  - by Leopold_Bloom

  So I was installing questionable operating system onto my EEE pc and it required me to downgrade the BIOS which I really am not an expert at. I used a patch and it appeared to work. Now, I'm paranoid about the downgrade because, honestly, I have no idea where the code came from or what could be in it. My question, then, is it possible to "start over" completely fresh with my BIOS? As in wipe out the possibly malicious BIOS and go back to the manufacturer-provided one? Has anyone done something similar to this? I just want to install Ubuntu Netbook Remix to the EEE pc 1000 but I want to make sure the BIOS are secure. Any advice would help tremendously, or am I just being uber paranoid? BIOS are definitely not my strength.

• Access points fighting for dominance?

  - by Phillip Oldham

  We have a small office with a large number of wireless devices (a mixture of desktop machines, laptops, and wifi-enabled phones) all working from a single Apple Airport Extreme which extends our wired network. I've added another Airport Extreme for resiliency, since we've been seeing a decrease in performance and (as far as I understand) access points can only handle a small number of clients. I set the new AP to extend the current network so that the clients weren't constantly switching between different wireless networks, however as soon as this AP was configured all the wireless devices started seeing network trouble, flicking on and off. I'm assuming that this is because both APs are reasonably strong, and the client can't decide which to use. What is the best route to follow to resolve this? What I'm aiming for is wireless resiliency; preferably having two APs share the network load, or if this isn't an option then having a primary AP with a "fail-over", should the primary go down for any reason.

• Windows 8.1 touchpad three-finger-multitouch gesture gone

  - by THEVAN3D

  Couple of days ago, i installed the Windows 8.1 Pro WMC and all of a sudden the touchpad gesture, which worked like a charm back in Win 8.1 preview, Win 8 and even Win 7, just stopped working. I am talking about the "Three Finger Flick" feature, which is used to go back and forward in folders and/or internet browsers at first i didnt even have the left edge pull feature, but then i added some values in this key into regedit, and now i have it [HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh\ZoneConfig\TouchPadPS2\Left Edge Pull] I Googled that, i didnt know what to do by myself and i dont know where to write and what to write anything in order to get the three finger flick back too I installed various versions of drivers starting from about version 15 to the version 17.0.8.0 (the one that i currently have), and even though i have all the other gestures, taps and swipes working they are not in the device settings, there is no multitouch gestures in device settings so thats why i guess i have to write something in regedit, but again, i dont know what to write, and where to write. please help me if you can

• script Disk Management configuration

  - by Joseph

  I have 10 workstations with large monitors that have USB slots and several card readers built in. The card readers cannot be disabled and will map to drive letters when I image the computers. I go into Disk Management and delete the drive mappings and add mappings to a single folder in C:\ with a folder for each slot. I have to do this because of scripts that run that are expecting specific letter drive mappings to network resources. Is there a way to script the deleting and adding of drive mappings instead of having to use the Disk Management GUI manually on each workstation? The workstations are running XP Professional.

• Volume randomly turning itself down on Windows 7 64-bit

  - by Arda Xi

  This is the weirdest issue I've ever encountered with my PC. Every so often, my sound will start playing back at a lower volume. This happens when watching video, listening to music, all independently. It usually lasts anywhere up to a minute, after which it will turn up again. The weird thing about it is that the volume control in Windows remains at 100%, even though the volume is audibly a lot lower. (No, I'm not going deaf, it's just my PC. I checked.) I just have no idea where to go to troubleshoot this, even. I'm using Windows 7 64-bit with an on-board Realtek sound-card. Oh, just in case someone finds this question on Google or whatever, making sure this is on Do Nothing may fix your problem. Unfortunately, it did not work for me. My settings all seem fine. This is my audio slider. (Took the screenshot while the issue showed.)

• Name typing in the "TO" line for last name recognition

  - by Buck

  I have outlook 2010 on a Windows 7 laptop. When I go to send an email at the "TO" line and I start typing the name, if I start to enter the last name it will not recognize anyone in my contacts and will not auto-populate a list of all the names that fit the description of what I have typed so far. But if I start typing the first name first it will start this auto-choice feature based on what I have typed so far. The company I work for has 20k + employees and If I want to email someone like "Michael Hutch " if I type "Michael" it still gives me like 800 names to chose from. My old laptop that had 2003 Outlook on it, had this functionality. Is there a way to enable this in Outlook 2010?

• Internal message system with SQL database

  - by laurens

  Hi all, I was asked to install a -rather basic- Internal message system with SQL database we could integrate with our websites. A user is logged onto the website and should then be able to go to its Inbox or outbox; of course they should be able to sent to other users. Important: It's not a smtp/pop mailserver system I'm looking for! I found something with similar functionalities with an access DB (also a possibility) http://www.planet-source-code.com/vb/scripts/ShowCode.asp?lngWId=4&txtCodeId=6859 Thanks in advance!

• How to add a Mac to Windows Active Directory

  - by Ben Daniel

  I've gone into the Directory Utility on the mac, clicked on the services tab, entered the Active Directory Domain and Computer ID, clicked the Bind button and it showed a little status label which flickered through 5 of 5 steps and then said "An unknown error occurred". If I ignore the error and just click the OK button further down the screen and make sure the Active Directory service is ticked in the list of services, then go to the Directory Servers tab and try to add an Active Directory by entering my ad domain, computer id, admin username and password I get an error "Unable to add the domain. An unexpected error of type -14090 (eDSAuthFailed) occurred." Any ideas?

• HDD situation - what would be best - data and backup

  - by Sam Johnson

  I just installed W8 on an Intel 330 180 GB SSD. I have 3 1TB HDDs. 1 HDD will be external for backup. 2 HDDs are then available for my PC. I do not need 2 TB of storage, so I thought I'd set these up to be exact clones of one another, so that if one dies I have a backup in the computer to go along with my external. Is this a good set up? How best would this be accomplished? I've heard people suggest RAID but I've never done RAID, have no idea what it is, and have no idea how to set it up in my BIOS. Thanks in advance

• Using Windows 7 XP Mode for games

  - by Josefvz

  Hi all. I have Win 7 (x64) at home and I want to play some old games (specifically Lands of Lore 3, but also some others). This game does not work properly on Win 7, and there are no patches that I'm aware of to fix its issues. Can I use XP Mode to play this game (and other non Win 7 nice games), or is there a better way? I only have one PC and dual booting scares me... (so no to dual booting!) Another question: Will I have full hardware support (full use of my graphics card, etc) when I use DOSbox or a VM? I have decided to go with VirtualBox or vmware, I'll check which one gives the best performance, thanks for your input!

• Exchange Management Console Listing Extra Servers

  - by Zak G

  I recently decommissioned an Old Exchange 2003 server. Prior to the decommissioning, the environment consisted of 2 EXCH 2010 and that one EXCH 2003 server. I went through all the steps listed in Microsoft documents and online in how to remove the server completely (pruning the AD and all that jazz). When I go to Exchange Management Console it still lists 3 total servers in the "Server Summary" column in the Organizational Health tab. When I click manage servers, it only lists the 2 EXCH 2010 servers. I am aware this is only a cosmetic issue but I would appreciate it if anyone can share some advice on how to fix the issue.
