• Only some motherboards can support faster RAM?

  - by Wesley

  This is a question relating to one of my builds. Here are the specs: ECS P4VXASD2+ V5.0 motherboard Intel P4 Northwood 2.8 GHz (533 MHz FSB, 512 KB L2) 2x 1GB PC3200 DDR RAM Maxtor 300GB IDE HDD 16 MB NVIDIA TNT2 Pro AGP OKIA 300W ATX PSU Gigabyte 52x CD-ROM The issue right now is that I'm trying to install Windows XP from the CD drive but the computer randomly restarts partway through installation. My other build was BSODing due to RAM latency errors. This ECS board manual states that memory modules "up to 333 MHz" (i.e. PC2700) is supported. However, I am running PC3200 modules, which is clearly faster than PC2700. Would this be causing the computer from randomly restarting? EDIT 1: I also wanted to mention that my Emachines T2482 is actually running 2x 512MB PC3200 DDR RAM when it should only be supporting PC1600 and PC2100 DDR RAM. Yet there are no issues with it.

• can't access SAMBA shares on UBUNTU-server from other computers

The server is connected by LAN. On one computer running windows XP I can see the server but are not allowed to acces them. On another computer on the WIFI-net running win7 I cannot see the server at all but I can ping the server and I can see the smb-protocoll is running when sniffing with wireshark. I don't primarily want to use passwords, computers on the lan and wifi should be able to connect without any login-procedure. I'm sure my config is not sufficient but have hard to understand how I should do. Theres a lot of descriptions on the net but most is old and none have been of any help. I'm also confused by the fact that I can not se the sever on my win7-machine even though it communicates with the samba-server. Would be very happy if anyone could spread some light over this mess.

• How can I make gitosis distinguish between two users with the same username

  - by bryan kennedy

  I have a gitosis system that seems to be working correctly except for a common problem we run into where I can't distingush permissions between two users who have the same username, but different hosts. For example: [email protected] 's SSH key is in the key folder. And so is [email protected] 's SSH is also in the key folder. These two jsmith's are two different people on two different computers. However, when I configure them in the gitosis.conf file with the usernames jsmith@computer or jsmith@machine, it seems like each user just gets the same permission. Can gitosis not distinguish the full username (name and host)? If not, how do I deal with multiple users accessing our system with common usernames? Thanks for any help.

• How does operating system software maintains time clocks?

  - by Neeraj

  Hi everyone, This may sound a bit less relevant but I couldn't think of a better place to ask this question. Now consider this situation, you install an OS on your system, set the timezone and time, do some stuff and turn it off. (Note that there is no power going in to the computer). Now next time (say after some hours or days) you turn it on again, and you see the updated time. How is this possible even when my computer is not connected to the internet and was consuming no power during the period it was down.(Is there some kind of hardware hack?) please clarify!

• Virus blocking incoming connections ?

  - by Benoît

  Hello, on my windows 2003 server, all incoming connections are dropped. I can see them getting in using Wireshark, but even a single ping from another computer fails. All locally initiated connection work fine (i'm asking from the server). This server is the DC/DHCP/DNS/File server, so computer clients are in the dark. I've run varius antivirus and removal tools without any luck. The Windows Firewall is disabled. I'm wild-guessing at some virus/worm. How can i check why these incoming ICMP/TCP SYN/etc are dropped ? Anyone has any knowledge about such situations ? Thanks.

• Temp profile used when User logs in

  - by TJ

  One of my users logged into his computer, Windows XP, last night only to be meet with an error message that it could not load his profile and he will be logged in using a temporary profile. Typically when this happens I shut the machine down and restart and the correct profile will load when they log in again. Not this time. In the user profile options under computer-properties-Advanced-user profiles it show that there are three profiles with his name. Two are the exact same size with the same modified date (5/5/10) and the other is what I would expect size wise for a new profile with a modified date of today. What are my options to restore his profile?

• Using PC or Mac keyboard as Bluetooth keyboard for iPad?

  - by Kevin Hakanson

  I would like to use my computer keyboard (USB) as a Bluetooth keyboard for my iPad, while I am using it with my computer. I was hoping their was an "app for that" that I could run on either Mac or Windows. I imagine how it would work: It would have to emulate a Bluetooth keyboard, and be able to pair with the iPad. Then, when you give focus to this app, it transmits keystrokes from your built-in keyboard out over the Bluetooth connection. Seems simple, but I can't seem to find anything definitive on Google. Has anybody done this? I figure this is cheaper that buying a Apple iPad Keyboard Dock or a Apple Wireless Keyboard from the Apple Store. Also, it's one less item on my desk, which gets cluttered enough with one keyboard.

• Can't bring NAT to work

  - by user31738

  Hello, I bought a D-link DIR-300 wireless router and i can't bring NAT to work, i have an ssh and http service i need to forward to the internet. My connection is as follows: I have an ADSL connection, i'm using a ADSL ethernet modem connected and working, it doesnt let me put it on bridge mode. I have my router connected to my adsl modem through ethernet, it gets its ip through DHCP (and i'ts always the same) I have a desktop computer running linux with apache and openssh configured and working, it has fixed ip. I configured the NAT in the modem forwarding port 22 from the router ip to the internet. In the router i setup NAT forwarding port 22 from the desktop computer fixed ip to out there. This setup already worked with a fonera i had before, can anyone help me with this or tell me what kind of tests do i need to do? How can i test if the router is forwarding ports correctly before the modem?

• Best Performing Remote Desktop Software for WAN

  - by Dave

  I've been tasked with connecting a computer in one of our branches in the midlands to one in south wales. We have been using windows remote desktop but find it too slow. The ADSL on the computer were connecting to is about 6Mb Download and 470Kb Upload so not majorly fast. That connection is also shared with about 10 other internet users. I'm trying to find out if the is any remote desktopn connecting software that performs better than the microsoft remote desktop software. Or, would i be better using a KVM over IP? I've looked into connecting the offices through BT's fiber optic but at £21k a year rental were trying to find a cheaper solution! Any help would be great. Thanks, Dave,

• Bridging a Windows 7 and Ubuntu dual boot inside an OS

  - by matsko

  I have Windows 7 and Ubuntu installed on my local PC. They're both installed on separate partitions on the same machine, and when the computer boots up the user is given the option to choose which one they want to boot use as the OS. This all works fine, but I want to use Windows 7 instead of Ubuntu, I am required to restart the computer and boot up the other OS. Is is possible to use an "inline" tool that will allow to change between both OSs as if they were windows in Windows 7? Which tool would that be? Does anyone know of anything else than Parallels? Also are there any free tools that would do this?. Many Thanks.

• ERP/CRM Systems. Desktop Based ? Web based?

  - by Parhs

  Hello guys... I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first expirience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year i worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally i believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can tek heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Ofcourse browsers support shortcuts but the way to overide the defaults that browsers uses isnt cross compatible... That is a hudge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness?What kind of application would you use?

• Were the first assemblers written in machine code?

  - by The111

  I am reading the book The Elements of Computing Systems: Building a Modern Computer from First Principles, which contains projects encompassing the build of a computer from boolean gates all the way to high level applications (in that order). The current project I'm working on is writing an assembler using a high level language of my choice, to translate from Hack assembly code to Hack machine code (Hack is the name of the hardware platform built in the previous chapters). Although the hardware has all been built in a simulator, I have tried to pretend that I am really constructing each level using only the tools available to me at that point in the real process. That said, it got me thinking. Using a high level language to write my assembler is certainly convenient, but for the very first assembler ever written (i.e. in history), wouldn't it need to be written in machine code, since that's all that existed at the time? And a correlated question... how about today? If a brand new CPU architecture comes out, with a brand new instruction set, and a brand new assembly syntax, how would the assembler be constructed? I'm assuming you could still use an existing high level language to generate binaries for the assembler program, since if you know the syntax of both the assembly and machine languages for your new platform, then the task of writing the assembler is really just a text analysis task and is not inherently related to that platform (i.e. needing to be written in that platform's machine language)... which is the very reason I am able to "cheat" while writing my Hack assembler in 2012, and use some preexisting high level language to help me out.

• Looking for suggestions: becoming a hireable, young programmer [closed]

  - by Dan

  I am a 17 year old Java programmer that has filled the last year with learning all of the ins and outs of Java - Using Eclipse, and the help of a friend of the family (a Java programming architect for some company), I have learned everything from serializing objects, basic networking, generics, reflection, multi-threading, code optimization and efficiency & some concurrency safety - built my own proxy class, and nowadays, I answer questions on Project Euler. I am seeking some suggestions though on where I go next, or where I go from here to get a job in programming. I dedicate at least an hour every day to coding, sometimes literally, the entire day, and I really have come to love the process. I just started reading Effective Java (v2), and learning Scala (as I see often, possibly the Java replacement) I will be going to college for Computer Science next year - and taking AP computer science this year (however, I took a practice exam and got an 87, only need a 60to70 to pass, so no need to study for it too much) -- I was wondering if getting the SE 7 OCA and OCP would help me in trying to get a programming job. I looked around and most people have said online that an OCA/OCP are practically useless, but, at my age do they make me any more credible? More or less, what would you recommend to get a job in programming these days - or distinguish yourself from the crowd? I have enough time and dedication to learn another language, or anything really. Thank you very much.

• Prevent Ultrabay HDD from ejecting on sleep

  - by Bryce Evans

  I have a lenovo T430s thinkpad with a small SSD primary drive and 500gb ultrabay drive. When I put the computer to sleep and then return, I get the message titled "problem ejecting < drive name " "Windows can't stop your 'Generic volume' device because a program is still using it." This pop up is very annoying every time every time I use the computer. I don't want to disable write caching [D:Hardware[drive]policiesquick removal] because I want best performance and never remove the drive. Any ways to avoid this pop up?

• GRUB Error after Deleting Linux Partition

  - by Nironan12

  I was dual-booting with Windows 7 and Windows Vista each taking up half of my hard drive. In Windows 7 I used Easeus Partition Manager to shrink my Windows 7 volume 8GB. On the unallocated space, I installed Linux Mint 8 RC1. After a little bit of playing around with it, I booted in Windows 7, used EPM again and deleted the 8GB Linux partition. I then extended Windows 7 on the 8GB. After restarting my computer, all I get is a black screen and this: GRUB loading. error: no such partition grub rescue> I do not have a Windows 7 disk nor does my computer come with Startup Repair. What do I do?

• OpenVPN to connect remote networks, peer to peer instead of client/server possible?

  - by John Robertson

  I would like to connect two remote networks using OpenVPN. I am very new to this we are very small and don't have a sys/network admin. What are the possible setups to have both networks both live on a common LAN via OpenVPN? I would prefer to use the UDP peer model rather than client/server. Is there a way to set that up instead? I can't see how because no computer on existing network A has a routable address to any computer on existing network B and vice versa.

• Upgrade from Linux Mint 12 to Kubuntu 12.04?

  - by MountainX

  Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

• Is It Possible to Change Default Windows Idle Time for Task Scheduler?

  - by alharaka

  From the official Microsoft docs: Detecting the Idle State The Task Scheduler service will verify that the computer is in an idle state every 15 minutes. The computer is considered idle if all the processors and all the disks were idle for more than 90% of the past 15 minutes and if there is no keyboard or mouse input during this period of time. Besides, any presentation type application that sets the ES_DISPLAY_REQUIRED flag will make Task Scheduler to not consider the system as being idle. In Windows 7, Task Scheduler considers a processor as idle even when low priority threads (thread priority < normal) execute. Is there any way to change the time to less than 15 minutes minutes? Am I assuming this hard-coded and impossible? My Google-fu has eluded me so far and I found nothing, but wanted to check here before giving up.

• Windows Server 2003 W3SVC Failing, Brute Force attack possibly the cause

  - by Roaders

  This week my website has disappeared twice for no apparent reason. I logged onto my server (Windows Server 2003 Service Pack 2) and restarted the World Web Publishing service, website still down. I tried restarting a few other services like DNS and Cold Fusion and the website was still down. In the end I restarted the server and the website reappeared. Last night the website went down again. This time I logged on and looked at the event log. SCARY STUFF! There were hundreds of these: Event Type: Information Event Source: TermService Event Category: None Event ID: 1012 Date: 30/01/2012 Time: 15:25:12 User: N/A Computer: SERVER51338 Description: Remote session from client name a exceeded the maximum allowed failed logon attempts. The session was forcibly terminated. At a frequency of around 3 -5 a minute. At about the time my website died there was one of these: Event Type: Information Event Source: W3SVC Event Category: None Event ID: 1074 Date: 30/01/2012 Time: 19:36:14 User: N/A Computer: SERVER51338 Description: A worker process with process id of '6308' serving application pool 'DefaultAppPool' has requested a recycle because the worker process reached its allowed processing time limit. Which is obviously what killed the web service. There were then a few of these: Event Type: Error Event Source: TermDD Event Category: None Event ID: 50 Date: 30/01/2012 Time: 20:32:51 User: N/A Computer: SERVER51338 Description: The RDP protocol component "DATA ENCRYPTION" detected an error in the protocol stream and has disconnected the client. Data: 0000: 00 00 04 00 02 00 52 00 ......R. 0008: 00 00 00 00 32 00 0a c0 ....2..À 0010: 00 00 00 00 32 00 0a c0 ....2..À 0018: 00 00 00 00 00 00 00 00 ........ 0020: 00 00 00 00 00 00 00 00 ........ 0028: 92 01 00 00 ... With no more of the first error type. I am concerned that someone is trying to brute force their way into my server. I have disabled all the accounts apart from the IIS ones and Administrator (which I have renamed). I have also changed the password to an even more secure one. I don't know why this brute force attack caused the webservice to stop and I don't know why restarting the service didn't fix the problem. What should I do to make sure my server is secure and what should I do to make sure the webserver doesn't go down any more? Thanks.

• Server 2008 Likes to restart itself

  - by Campo

  I have a weird issue here. I notice about once a week the web server restarts itself. This would be only a minor issue if we were not planning on implementing an IP failover. I have checked the event logs. I don't see anything that indicates a reason for the restart. I need some help diagnosing the reason the server restarts. It happened last night at 5:00AM Last even in the log was 1 hour before the unexpected shutdown. Here is the Log for the shutdown event. Any help is much appreciated.

• Rhythmbox - put a playlist on my iPod

  - by GorillaSandwich

  I have an old iPod nano and currently use iTunes in Windows to management. However, I'm trying to switch to Ubuntu. So far, iPod management is one major holdup. Besides being unable to easily manage podcasts, I also don't see a way to create a playlist and put it on my iPod. I can create a playlist on the computer in Rhythmbox, but I can't drag and drop it onto the iPod. I can create a playlist on the iPod itself, put I can't drag and drop songs from my library into it. If I right-click the songs, I can add them to playlists on the computer, but not on the iPod. How can I create a playlist of music in Rhythmbox and sync it to my iPod?

• Looking for Fiddler2 help. connection to gateway refused...just got rid of a virus?

  - by john mackey

  I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed. Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.
