• Using an old PC case and power supply as a HDD Enclosure?

  - by mexiq

  I have 5 HDD and my computer is not handling the situation very well. hehe There are some towers that I can buy to put 4 of my drives out, but I'm thinking that I could use the power source of a failed computer I have and use it to power the 4 (or at least 3) of the drives. The data cables (SATA) will remain connected to the working computer (so no USB solution). The problem is that the power source will not work unless it is connected to the failing computer motherboard. Is there any way I could use the power source without plunging it to the old motherboard? Any "HOW-TO" links may be useful as well.

• Is email encryption practical enough?

  - by Dimitri C.

  All emails I have ever sent were sent as plain text. Like postcards, everybody on the way to the addressee could easily read and store them. This worries me. I know privacy is something of the past, but encrypting email is possible, at least in theory. However, I wonder whether it is practical enough. Is there anybody who has experience with email security? Is it easy to set up? And can you still send and receive email from all you friends and acquaintances?

• Idle VMware Guests Resource Consumption

  - by Ravenor

  I want to setup a number of guests with multiple CPUs (4) and at least 4Gb ram running Ubuntu Linux. These machines will mostly be idle, but from time to time their workload will require all their resources, especially the CPU. The hosts are ESXi 5.x. The question is, am I right in thinking that the resource consumption of the machines when idle will be negligible? We know this true of disk and the CPU. The only concern left therefore is memory. Since ESX over-commits memory it makes sense that unused memory of any guest is paged out. If my thinking correct?

• Can't connect to database in dreamweaver

  - by ReallyGoodPie

  I used to have this error in Dreamweaver CS6 and I would simply place the _mmServerScripts folder into the root of my local website. Every time I go to select a database it get this error: I have been searching the net for at least 2 hours now trying to find a solution. It is becoming quite annoying. Everything is working perfectly fine. All the server settings are 100% correct. I have seen various videos on youtube where the user is using a mac and they simply go and grab the _mmServerScripts folder from their dreamweaver folder but I can't seem to locate this. I used to simply use _mmServerScripts folder from dreamweaver CS5.5 and it would end up working perfectly. I don't know how to fix the issue so does anybody have any idea?

• Using DD for disk cloning

  - by roe

  There's been a number of questions regarding disk cloning tools (yes, I did search for it) :) and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all run of the mill bootable linux distributions. To my question, what is the best way to use dd for cloning a disk. I don't have much time to go around, and no test-hardware to play with, so I need to be prepared, and it's pretty much a one-shoot chance to get it done. I did a quick google search, and the first result was an apparent failed attempt. Is there anything I need to do after using dd, i.e. is there anything that CAN'T be read using dd? Thanks!

• OSSEC agent behind NAT

  - by Eric

  I am working on an OSSEC deployment where I will have multiple agents behind 1 public IP. Below is an example of the setup Private Network OSSEC-Agent1 (192.168.1.10) OSSEC-Agent2 (192.168.50.33) OSSEC-Agent3 (10.10.10.1) Those IPs NAT to 1 public IP (1.1.1.1) Then 1.1.1.1 talks to the public OSSEC server on 2.2.2.2 I've read some OSSEC documentation talking about NAT here, but it doesn't tell me exactly what I need to know. Their example is using an entire /24 subnet and mine will mainly have multiple agents to only 1 public IP. With the setup so far, I brought Agent1 online fine and it is communicating to the OSSEC server. However Agent2 continues to fail trying to connect to 2.2.2.2. Even though when I added the key, I had the correct name for it, so I know it talked to the portal at least once for that information. I'm assuming it's just getting confused with the multiple keys to 1 public IP. I basically want to know if this is possible and/or if I'm just overlooking something simple. Any help would be greatly appreciated.

• Lots of 408 Request Timed Out from same IPs

  - by GreatFire

  Web server: Nginx. Checking our log files, there are many log entries of connections that: take 59-61 seconds send an empty request (or at least none is logged) result in a 408 response (request timed out) do not contain any http_user_agent originate from a limited number of IPs We are monitoring average times to serve responses and this obviously inflates our statistics. Apart from that though, is this a problem? Any idea why it is occurring? Does it suggest that somebody is intentionally messing with us? What should we do?

• Live CD with good anti-virus software to scan/repair Windows?

  - by overtherainbow

  Hello, I browsed through the archives, and it seems like there's no live CD from which to run a good, up-to-date anti-virus application, at least to check whether a Windows host has been compromised The Ultimate Boot CD has only three AV applications, and their virus definition is from... 2007 In a report, ClamAV scored very low. It's nice that it's open-source, but if it's not as good as commercial alternatives... Those of you into this kind of thing, do you confirm that there's just no good live CD to inspect Windows hosts, and possibly repair them? If there is, what do you recommend? Thank you.

• Excel Conditional Formatting Multiple Data Bars and Data Icons in one cell

  - by wbeard52

  I am using Excel 2007 on a windows machine. I am attempting to place one data bar and one data icon into a cell under the conditional formatting. The issue is that I don't really want to have data icons or data bars for cells that have dates in the future and I only want to have data icons for dates in the at least one month in the past. This is what I have: This is what I want: I am using the EOMONTH function to determine the last day of the month for the conditional formatting calculations. For the data bar the formula is =EOMONTH(Now(), 4) and =EOMONTH(Now(), -1). The data icons formulas are =EOMONTH(Now(), -1) and =EOMONTH(Now(), -2) Is there a way in Excel 2007 to get rid of the data icons for all the dates in the future and lose the data bars when the date has past. Thanks

• Theoretical Wi-Fi decay

  - by lithiium

  Is there a way to (theoretically at least) calculate the decay on bandwith of a Wifi related to the streght signal? For example, I know that I can theoretically expect 54Mbps of a 802.11g at 100%, which will be the bandwith expected at a 30% of signal? is it lineal? is it the same? I could not find any source for this, but considering the error replay involved, I guess it should be possible to calculate something like this. Anybody knows?

• Migrating from Apache2 to Lighttpd creating errors in PHP/mySQL?

  - by Jean-Philippe Murray

  Ok, I've been using basics ubuntu LAMP setups for years now, and I wanted to give lighttpd a try. My LAMP setup run in a virtual machine with scripts running just fine. So I created a new virtual machine, starting with a fresh install of ubuntu and made my setups. On this new VM, lighttpd + php works just fine. (Or at least it seems...) Problem occurs when I take the scripts from my LAMP setup and upload them to the new VM. I'm getting : Warning: mysql_real_escape_string(): Access denied for user 'www-data'@'localhost' (using password: NO) My lighttpd setup is configured as php-cgi but not my apache2 setup. Could this be the source of the problem? I think that scripts would be independent of the server configuration, so I doubt it. Also, I know that my DB connexion informations are good (as I can log in via phpmyadmin perfectly). I'm in the dark here, any pointers ? Thanks,

• Lost disk space in Windows 7, cannot find the missing

  - by Tsanders

  My hard drive is complaining it is low on disk space, but a strange thing seems to be happening: Explorer reports 10Gb of available space (on a 120 Gb hard disk), chkdsk in the command prompt does the same but if I use a disk space tool such as SpaceSniffer or WinDirStat, only 50Gb of data is found. My guess is that there somehow is a hold on a large block of disk space (but that's just a guess) because of a prior very large (40 Gb) download attempt that didn't complete. There isn't 40Gb of files on the drive (hidden or visible), yet Explorer insists that something is there. How can I claim back this hard disk drive (without formatting my hard disk)? SpaceMonger is providing a clue, reporting four unscannable folders which add up to 43Gb: C:\RRBackups C:\System Volume Information C:\Windows\Csc\v2.06 C:\Windows\System32\LogFiles\Wmi\RtBackup Does anybody know what these folders are for, and how I can claim back at least some space? Restore point claims about 4Gb, so that doesn't seem to be the main problem.

• How to check for the existence of a response header in Nginx rules?

  - by Victor Welling

  Setting up the rewriting rules for the request proved to be quite easy in Nginx. For the response, not so much (at least, not for me). I want to strip the Content-Type header from the response if the Content-Length header of the response isn't set. I have the NginxHttpHeadersMoreModule installed, so that should allow me to remove the header, but I can't seem to find a way to check for the existence of the Content-Length header of the response using a rule in Nginx's configuration. Any suggestions on how to do this would be most appreciated!

• IIS7 defaulting to default.php instead of default.aspx

  - by emzero

  Hi guys. My client has just got a new dedicated server running Win2008 (we had 2003 before), II7, etc. I started setting a little ASP.NET 2.0 web application we have. Running on its own AppPool 2.0. The problem is that when I browse the site root (locally or remotely), I get 404 because the url now points to http://domain/default.php, when it should be default.aspx. Yes, I've checked the Defaults Documents settins for the website and I deleted everything but default.aspx (default.php was not even listed). To finish, I'll say that if I navigate to http://domain/default.aspx, the site works perfectly and I can follow links without problem. Any idea why is this happening? Or at least where I should start looking? Thanks!

• Making a tab key on the right side of a full sized mac keyboard

  - by StoneBreaker

  I use mac OSX with a full sized keyboard (F1-F19, number pad arrow keys and FN, Home, End, Page UP/Down delete mini pad above the arrow keys). My mouse is on the left side of the keyboard. This allows use of the return key, the arrow keys and the number pad etc. with my right hand. I would like to assign a key or key combination on the right side of the keyboard to operate the same as the tab key. I am thinking a Function key or the Home key, or FN+?? I have QuickKeys and could use that if someone knows how. If there is no way to make a key the equivalent of the tab key, then at the least I would like to make some equivalent to Cmd+Tab that I can use with my right hand. Thanks for any help and ideas.

• How can I uninstall AppFabric?

  - by downatone

  I recently upgraded from Win 7 - Win 8. AppFabric was not one of the programs that came up as being incompatible when I ran the upgrade wizard, so I did not uninstall it. Now whenever I goto "Add or remove features" I get the following error: --------------------------- Windows Server AppFabric Setup Wizard --------------------------- Windows Server AppFabric is not supported on current operating system Windows 8 Pro(version 6.2.9200.0). Please refer to installation guide for the list of supported operating systems. --------------------------- OK --------------------------- Unfortunately the only way to uninstall AppFabric is via the "Add or remove features" - does anyone know a commandline command to kick the uninstall so I can at least access "Add or remove features"? Edit: C:\Windows\System32\AppFabric\Setup.exe /remove Throws the same error as above.

• Best way to keep a MS DOS application alive? (Virtual MS DOS)

  - by user11010

  Hi, I have a good old DOS application which is still required to run. Unfortunately the PC is dying and needs to be replaced. The PC was running Windows 98 and the software was executed in a MS Dos Command line. When we would order a new PC you would at least get a Windows XP which has the Win 2000 (NT) Kernel and is not DOS based. Now I need a strategy to be able to run a that DOS application on a new age PC. What I was thinking is to buy a standard office box and have a virtual PC or VMware setup which is running MS DOS and my DOS application? Would this be a way to go? Any concerns? What about 16Bit/32Bit… So any opinion, experiances or tip would be great …. Thanks

• How can I install CentOS without a keyboard, mouse, or monitor?

  - by user1032531

  I will be buying a new computer which will be used as a CentOS server. I will put it on my home LAN, and once it is set up, will access it only through SSH. I don't want to spend a lot of money (maybe $500), and I don't want to buy another monitor or keyboard just to through them away after the server is setup. My question is how do I access the computer without a keyboard and monitor when I install the operating system? For media, I can use either the DVD or an ISO on the USB, so am good there. But how do I see what I am doing and enter commands without a monitor or keyboard? I have a Window 7 laptop, an XP laptop, and a CentOS laptop. Can I use one of my laptops to act as the MMI (Man Machine Interface)? If not, what is the easiest and least expensive option? Thank you

• Ping / Trace Route

  - by dbasnett

  More and more I see programmers developing web based applications that are based on what I call "ping-then-do" mentality. An example would be the application that pings the mail server before sending the mail. In a rather heated debate in another forum I made this statement, "If you are going to write programs that use the internet, you should at least have a basic idea of the fundamentals. The desire to "ping-then-do" tells me that many who are, don’t." On this forum and at Stack Overflow I see numerous questions about ping / trace route and wonder why? If it is acceptable to have a discussion about it here I would like to hear what others think. If not I assume it will be closed rapidly.

• Can you swap dpi buttons on the Astra Dragon War mouse with 4th and 5th buttons?

  - by Denny Nuyts

  I'm left-handed and I'm in need of a good computer mouse with at least five buttons. However, most computer mice on the market are sadly right-handed and very impracticable to use with the extra buttons on my pinkie side instead of on my thumb side. The Dragon War Astra has two buttons on both sides. Buttons 4 and 5 on the left side and the dpi-buttons on the right side. If I were just able to re-assign them so they swap positions I'd have a great left-handed mouse. Sadly, the program X-Mouse Button Control doesn't allow the user to re-assign dpi buttons. My question is whether there exist other methods to still get it to work for me (third party programs, perhaps?). Or should I get another gaming mouse?

• Virtual guest does not have network access in cafe.

  - by blee

  My Virtualbox guest OS (Ubuntu on ubuntu host) does not connect to the internet when I have wifi access through an internet cafe system. By this, I mean where your browser redirects to an internal web page where you can enter a code. On the guest, I can successfully connect to the virtual network adapter, but I do not get internet access, nor a redirect to the internal web page. I use OpenDNS for the host. I have no problems when connecting through ethernet or regular wifi. Can someone tell me any of: 1) How to fix the problem. 2) How such cafe systems work. 3) At least point me to a technical explanation of such a cafe system so I can begin to troubleshoot. Thanks!

• Project management software that syncs with smartphone?

  - by overtherainbow

  Hello, I went through the archives here and the Wikipedia page on Project management software, but didn't find information on this type of application to manage projects: Native Windows application (don't like web-based solutions; prefer native to cross-platform) Free or affordable, ie. not an Enterprise solution Scalable from one to a few concurrent users Like MS Projet et al., a project consists in tasks which can be further divided into sub-tasks, and the whole thing is displayed in an tree list An item that has a date set (either start/due) must be displayed in a Calendar view, so it's easy to know what work must be done each day The Calendar view must somehow sync with smartphones (at least BlackBerry) At this point, the apps I know either don't provide a Calendar at all, or do but they can't sync with smartphones, which forces me to copy/paste scheduled items into Outlook so they are synced with my BlackBerry :-/ Thank you for any help.

• SQL Server Analysis Services 2005 crash when disk is full?

  - by squillman

  One of our SQL boxes ran itself out of disk space last night. This particular server has both the database engine and analysis services on it. Database engine was not happy about having no disk space on the volume where all the data files are, but analysis services just plain died. At least, the only thing I have to blame is the full volume. Has anyone experienced a SSAS that they've been able to directly tie to no disk space? I've got nothing else in the SQL or event logs to blame...

• Video for HTML5 -- ffmpeg commands

  - by StackOverflowNewbie

  I'd like to allow my users to upload their videos (no clue what format they'll be) and convert them into the following formats: MP4 Ogg Webm I think it's those 3 formats I need in order to support HTML5, at least per http://mediaelementjs.com/. I've tried various commands that I found on the web. Some of them worked, some of them used old syntax, some of them worked only on my computer and not others, some of them gave conflicting information, etc. Are there any FFMPEG experts here that can provide the "proper" commands? I'm not particularly trying to achieve anything special. I just want to be able to convert the video into something playable on the web. Highest quality, smallest filesize, etc. are the basic goals. Something that works without a lot of special configurations would be ideal, too. I ran into a lot of "missing presets" problems.

• Dropbox won't connect on Ubuntu 10.10 (Waiting For Connection)

  - by slhck

  I run Ubuntu 10.10 (2.6.35-25) on an x86 machine and try to install Dropbox by downloading the latest .deb file from the website. Now, first it will install dropbox-nautilus (requiring me to restart Nautilus before that) and then ask me to start Dropbox itself. The Dropbox client opens and indefinitely waits for a connection as there is a connection error. Of course, I don't use a proxy server and I'm writing this post from this very machine, so there's no problem with the internet connection. I'm not using a firewall (at least not that I know of, the Ubuntu installation is relatively untouched so far). Does anybody have some pointers?
