• Microsoft CA certificate templates expires sooner than expected

  - by Tim Brigham

  The certificates my Microsoft CA is generating do not match the time period indicated in the template used. How can I resolve this? I recently created a new certificate template for use on my Linux boxes on my Microsoft CA (2008 R2 Enterprise). This template is approved for server and client authentication purposes with a validity period of 10 years - the expected lifetime of our Linux boxes - and the subject name supplied in the request. I have checked both the intermediate and offline CA - both have more than 10 years of life listed. Is there some kind of hard limit I'm hitting here?

• What are those white circles on the desktop in Gnome 3?

  - by monk

  I have Fedora 20 with GNOME 3.10.2. On the desktop background (i.e. where the wallpaper is), there are five small white circles centered at the very bottom of the screen. The first is filled, the others are not. I can click those circles, thereby changing which one is filled, like a radio button. I cannot for the life of me figure out what those circles are supposed to do, and it's starting to drive me crazy. Clicking and thus changing which circle is filled does nothing I can perceive, and there seems to be no configuration option anywhere that has anything to do with them. What are those things? Is there any way to get rid of them? Edit: I made a screenshot of my desktop with no programs running. You can see the dot/circle thingies at the bottom.

• Missing disk space in Windows XP

  - by Jørn Schou-Rode

  On my mother's Lenovo laptop, Windows XP claims that the hard drive is almost full. According to the properties window, 52.7 out of 55.2 GB is in use: By deleting temp files from Internet Explorer, System Restore, Recycle bin, Windows Update, System Cleanup, I managed to free up about one GB. That's still 50 GB in use, which still is a lot more than I expected. Hence, I gave good old WinDirStat a spin, and here's the output: It might be hard to read here, but the first line says that the total amount of disk space in use on drive C is 24.3 GB. So Windows claims usage of 52.7 GB and WinDirStat can only account for 24.3 GB. Where is the other half of that disk space being used? I hope someone has an answer, or some tricks or tips to do further research. UPDATE: The laptop in question has an SSD hard drive. I am aware that these disk (at least the earlier ones) have a limited life-time. Could the symptoms described be caused by wear and tear on the SSD?

• Reliable 1tb or larger hard drive?

  - by jasondavis

  I am in the market for 2-3 new drives, I would like each to be at least 1tb to 2tb in size. I have been reading all the reviews on newegg.com for 1tb and larger drives and they all have 1 thing in common. Almost all the ones I read about have complaints of them being DOA or dieing within a few weeks of use. I am hoping to find some drives with this storage range that have a reputation for lasting a long time instead of a short life. Please help me if you have any experience with these sort of drives? Most the ones I read about were Western Digital brand. I realize some might complain that this questions answer would be based upon a timeframe, so if a user searches and find this answer a year from now it will be outdated but I would appreciate any help based on the current hard drives available as of April 10th, 2010 on newegg.com

• Funnelling http traffic

  - by spencer p

  I have a situation where a large batch of servers (X), on demand, need to request data from a smaller set of web servers (Y). The worst case scenario is if all servers in X decide to fetch different requests to one server in Y. That would be X amount of connections, which could be a very large burst of traffic. The best case scenario is if 1 server in X hit 1 server in Y in tandem. Life does not work like this. One idea to entertain is placing a proxy, similar to squid between X and Y. All of X servers can connect to this proxy, but would result in a few persistent (http keepalive) connections to Y. If The few were say, 3 or 4, then it would funnel. If we could then rate limit those connections and traffic decides to spike unusually high, we wouldn't hurt anyone but ourselves. Thoughts?

• How to print 4 index cards on a single A4 sheet in Word 2003

  - by Anna

  I have an index card designed in Word. It's fairly complicated with graphics, borders and background. The page layout has been set to landscape and with size set to 4x6. How can I print this, 4x per A4 landscape sheet? I cannot for the life of me work it out. The printer always seems to do a single card per A4 sheet, wasting 3/4 of the page. "Pages 1,1,1,1" will result in 4 sheets being printed. What am I doing wrong?

• I accidentally hid my Gnome Panel

  - by Dean

  I got a new tablet pc, and in attempt to hide the empathy mail icon, accidentally made the entire panel dissappear. (The one at the top that has applications/places/system, and battery life/network connections etc). I don't believe I killed it, because alt+f2, then gnome-panel does not bring it back. I've tried alt+ctrl+backspace to reset gnome, that didn't bring it back. It must just be some setting like 'hide' or something... Any tips to get it back? Thanks.

• OS X 10.8.3 + attempt to change VPN settings = no more VPN access

  - by nicole

  I am running Mountain Lion and had gotten very tired of re-entering my password at random times when using my school's VPN network (I don't know much about these, but the type is Cisco IPSec according to the setup instructions I followed a while back). In an attempt to make life easier, I followed the instructions here, but, alas, any attempt to connect with VPN was met with the message "A configuration error has occurred. Verify your settings and try connecting again" (or something along those lines.) I then tried to do the steps in the blog post in reverse and change everything back. Upon (supposedly) doing that, though, a new error message came when attempting to connect to VPN: "The negotiation with the VPN server failed. Verify the server address and try reconnecting." Now I have no idea what to do. Is there a way to reset all VPN-related things in my system so that I can follow my school's instructions and just start over?

• Why do LCD screens need a backlight? (seriously)

  - by Tudor

  Bare with me on this, I'm well aware that most LCDs have backlights. But what if, they DIDN'T? I spend long hours in front of a screen and I hate the concept of staring into a lightbulb all the time and my eyes getting sore. I need to get a new lcd (some sort of IPS that doesn't cost a fortune) soon, but no matter what I'll get, I'll still be looking at a damn light. How come you can read on a kindle w/o a backlight but there aren't any monitors like that? I mean, ideally, a screen should be like a book or any other object in real life. Just for curiosity's sake, does anyone know of any new monitor concepts? Also, http://www.indiaonrent.com/view/l/laptop-transparent-monitor.html hah!

• How to make the jump from consumer support to enterprise support?

  - by Zac Cramer

  I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

• Django freezes when adding objects through the admin

  - by Quartz

  I have a Django 1.1 website running via Apache/mod_wsgi with a PostgreSQL 8.3.1 database. Recently, when I added objects through the admin interface, the connection froze up and I lost several worker processes, so I had to restart Apache. Upon trying to replicate this, I found that it only happens through the admin: if I go into the Django shell and issue the same insert, it works fine. Also, performing an UPDATE operation works without issues, so just INSERTs. I've rebuilt indexes on PostgreSQL and run a full VACUUM. Error logs don't show anything, and I can't figure out for the life of me what's wrong. Anyone have any ideas?

• How to use 2 or more internet connections on the same network?

  - by Rogue

  Living in a joint family we have 3 internet connections, each floor has one internet connection which is split per floor. Each internet connection is shared between 4-5 computers using a switch per floor. Each of these internet sharing networks are independent of each other. What I want to achieve here is a local network (for local messenger and file sharing) that can combine all the 3 independent networks, problem is that whenever I try to do that the whole network tends to use just one internet connection. I have all the necessary hardware. How do I solve this problem, one approach could be that I could get one PC to act as a server and bridge the internet connections and then the whole network would have to access the internet through this server. Theoretically this could be possible but I have never tried this approach in real life. Also if certain computers need be restricted from internet access how would this be possible on the same network?

• What useful things can one add to one's .bashrc?

  Is there anything that you can't live without and will make my life SO much easier?

• typesetting system

  - by itun

  All my life I used Microsoft Office on Windows for document writing and then Libre(Open)Office on Linux. This is not a bad software, but not perfect and I have some complaints. Now on my usual desktop I have Linux. I heard from people who work a lot with documents of different type and complexity (diagrams, articles, document design, presentation) that latex is a perfect thing. I have spent two days exploring Latex and my opinion as a beginner that it is out-of-date (the concepts of Latex language). The language is not intuitive and sometimes even complex. Can somebody advise another software product for document writing?

• What is the worst Mac OS X annoyance in your opinion?

  - by jasonh

  I'll start with multi-monitor support. I'm trying to set up a Macbook to use an external display and I can't for the life of me get it to move the Dock over to the external display. That and it won't let me disable the Macbook's internal LCD. Please put one item into each post so that the community can vote on each issue. Also please list any workaround if you have it and what version of the OS it applies to. Thanks!

• Do I need to run a verfication on LTO tape backups even though the drives themselves perform verification as they write?

  - by ObligatoryMoniker

  We have an LTO-3 Tape drive in a Dell media library that we use for our tape backups. The article about LTO on Wikipedia states that: LTO uses an automatic verify-after-write technology to immediately check the data as it is being written, but some backup systems explicitly perform a completely separate tape reading operation to verify the tape was written correctly. This separate verify operation doubles the number of end-to-end passes for each scheduled backup, and reduces the tape life by half. What I would like to know is, do I need my backup software (Backup Exec in this case) to perform a verify on these tapes or is the verify-after-write technology inherent in LTO drives sufficient? I would also be curious if Backup Exec understands the verify-after-write technology enough to alert me if that technology couldn't veryify the data or will it just ignore it making it useless anyway since even if the drive detecs a problem I would never know about it.

• Array filteration PHP

  - by Muhammad Sajid

  I have an array with values like: Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Birthday [childId] => 2 ) [1] => Array ( [parent] => Basic [parentId] => 1 [child] => Gender [childId] => 3 ) [2] => Array ( [parent] => Geo [parentId] => 10 [child] => Current City [childId] => 11 ) [3] => Array ( [parent] => Known me [parentId] => 5 [child] => My personality [childId] => 7 ) [4] => Array ( [parent] => Known me [parentId] => 5 [child] => Best life moment [childId] => 8 ) ) And I want to filter this array such that their filtration based on parent index, and the final result would be like: Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Array ( [0] => Birthday [1] => Gender ) ) [1] => Array ( [parent] => Geo [parentId] => 10 [child] => Array ( [0] => Current City ) ) [2] => Array ( [parent] => Known me [parentId] => 5 [child] => Array ( [0] => My personality [1] => Best life moment ) ) ) For that I coded : $filter = array(); $f = 0; for ($i=0; $i<count($menuArray); $i++) { $c = 0; for( $b = 0; $b < count($filter); $b++ ){ if( $filter[$b]['parent'] == $menuArray[$i]['parent'] ){ $c++; } } if ($c == 0) { $filter[$f]['parent'] = $menuArray[$i]['parent']; $filter[$f]['parentId'] = $menuArray[$i]['parentId']; $filter[$f]['child'][] = $menuArray[$i]['child']; $f++; } } But it results : Array ( [0] => Array ( [parent] => Basic [parentId] => 1 [child] => Array ( [0] => Birthday ) ) [1] => Array ( [parent] => Geo [parentId] => 10 [child] => Array ( [0] => Current City ) ) [2] => Array ( [parent] => Known me [parentId] => 5 [child] => Array ( [0] => My personality ) ) ) Could anyone point out my missing LOC?

• What is causing my internet to be slow on one laptop but not the other and only at a distance?

  - by Matt Case

  I have a newer laptop, purchased within the last year (acer aspire 7740). This laptop does not have any problem connecting to wireless networks and indicates that the signal strength is excellent on most of the wireless networks I connect to. When the laptop is within 10 feet of my wireless router it gets 30 down 10 up. When it is farther away than 10 feet it will be lucky to get 3 down and 1 up. I also have an older laptop, purchased in 2005, that has no problems at all at the same range. None of my phones, gaming consoles or tablets have this problem. I am beginning to think that the problem must be some hardware defect with the wireless card. I can provide additional information if needed. Just thought I'd check to see what others thought because I've been working on computers my whole life and have never heard of this happening. I have also tried to change the channels on my wireless router and have had no success with this idea.

• Animated HTTP request visualisation on Apache

  - by Simon Bennett

  This is more a question to appease my memory in trying to remember what it was I saw a while ago. I remember being introduced to a realtime server visualisation tool that showed the current requests that Apache was handling in a kind of fireworks effect on screen. Each request/group of requests would be shot across the screen in varying colours. I can't for the life for me remember what is was called and hunting around here and Google has left me empty handed. Just wondering if anybody else was able to plug this gem from the memory and ease my pain! Thanks

• Security: Unable to display current owner

  - by Jim McKeeth

  I have a user with local administrative rights on their Windows 7 64-bit box. They extracted a file from a zip file they downloaded with the Zip shell extension to their desktop on a non-encrypted or compressed NTFS volume. Unfortunately they cannot open it. I tried to take ownership of it and it just reports "Access is Denied" and for the current owner it reports "Unable to display current owner." At this point the file cannot be deleted, executed or modified. I have actually seen this exact same happen in Vista before, but I can't for the life of me remember how to fix it. Any ideas how it happened or how to fix it? I'd be happy just to delete it without a format at this point.

• Pentium 4 Computer Won't Power Up

  - by Harvey

  I have a faulty Pentium 4 workstation with data that I would like to retrieve. Here are the symptoms & what I've done so far: Machine is totally dead. Motherboard LED is lit but that is the only sign of life. I have replaced the power supply and bypassed the on/off switch. Tried a PC Analyzer motherboard tester but didn't have any power to the card. Unpluggged the P4 cable from the motherboard, hit the on/off switch, the power supply fan comes on and I get codes from the analyzer but nothing that seems to be of any value. Machine does not boot. Will not shut down by hitting the switch. Bad motherboard or could it be a bad CPU cooling fan?

• Why doesn't my laptop battery charge while the laptop is in use?

  - by larryb82

  Up until a week ago, my laptop has always been able to charge the battery while I'm using it. Now, it will not charge unless the computer is sleeping, hibernating, or turned off. The icon in the start tray states that the battery is charging but it is not animated (it used to be) and of course the power level does not increase. Otherwise, the battery seems to be fine. The battery life is decent (2h+) and while the laptop is in use and plugged in the battery will maintain a constant charge. Any troubleshooting help would be great (i.e. is this a charger issue, battery issues, software issue, etc...)

• Same command on multiple servers

  - by w00t

  Hello everyone. I'm just wondering if there is any fellow sysadmin with the need to execute one command on multiple servers. If so, what technique are you using? I have grown tired to ssh-ing to 3-5 servers and executing the same thing over and over again, so I'm thinking to make my life easier. Also, I think I should create keys so I don't have to enter passwords anymore (though I'm using root). After 2 years of doing this, I kind of developed a laziness. I googled it up, I know about cssh, pssh, tentakel (this one seems cool), and the more pro-genre - Puppet (of which I just heard of, didn't invest the time to read the docs). BTW, I'm using XP+putty, so if there is any putty-cool-thingy available, that's welcome too. If not, I can always ssh to one server and from there start my rest-of-the-servers-conquest :) *evil* Hit me up. Thanks.

• glassfish v3 - update all pakages via command line on linux

  - by orange80

  Does anyone know how to do this? I just want a one-shot command to "update everything" over the command line? This is for a remote server so it must be over the command line. I used: $ sudo pkg list -u to see the list of packages that are out of date, but I cannot for the life of me figure out how to say, "ok, update them". I have scoured the web for clues, but to no avail :( This is classic Sun Solaris-type patching that is the exact reason I am now on Linux. Please help!! Thanks :) Jamie

• App store for Windows

  - by Renaud Bompuis

  I'm wondering if there is any good App Store for Windows. I stumbled on allmyApps, and this question, but surely there are more out there. My dream Windows App Store would do things like: Allow me to download and install software Allow me to pay for apps Check which apps are already registered on my machine and keep track of them Keep track of all my machines Keep track of available upgrades and easily deploy them. Let me discover new apps that may be useful I know this is utopian on the Windows platform since development, upgrading, purchasing are so fragmented, but the Apple Store, Chrome App store, etc do make your life easier. Just trying to find something to ease the pain a little bit... So, are there any good services/software out there that would help me achieve some of the listed goals?
