• Telugu (unicode) font rendering in emacs

  - by Prakash K

  [I asked the following question in stackoverflow, and I have been redirected here. I hope I can get some answers here. My question at stackoverflow had two small images showing the example rendering of text. As a new user at superuser, I am not being allowed to include them here, nor I am allowed to post more than one hyperlink. And, I don't have enough reputation on SO to migrate that question. Please look at the stackoverflow question for the images. Sorry about the inconvenience.] I sometimes edit text in telugu language. However, when I open the file (UTF-8 encoded) in GNU emacs (version 23.1.50.1 on Ubuntu Jaunty) the text rendering is incorrect. The same text file opened in gedit is rendered correctly. Here's a snippet: ????????? ???? ???? ???????? rendred in gedit: Please see the SO question for the image showing telugu text rendering in gedit And, the emacs rendering of the same text: Please see the SO question for the image showing telugu text rendering in emacs Wherever glyphs need to be composited (not sure if it's the right word), emacs (or whatever library it uses) is not doing it right. Is there anyway to fix this? Perhaps tuning some setting in my configuration? Any ideas, please?

• Setting umask for all users

  - by Yarin

  I'm trying to set the default umask to 002 for all users including root on my CentOS box. According to this and other answers, this can be achieved by editing /etc/profile. However the comments at the top of that file say: It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates. So I went ahead and created the following file: /etc/profile.d/myapp.sh with the single line: umask 002 Now, when I create a file logged in as root, the file is born with 664 permissions, the way I had hoped. But files created by my Apache wsgi application, or files created with sudo, still default to 644 permissions... $ touch newfile (as root): Result = 664 (Works) $ sudo touch newfile: Result = 644 (Doesn't work) Files created by Apache wsgi app: Result = 644 (Doesn't work) Files created by Python's RotatingFileHandler: Result = 644 (Doesn't work) Why is this happening, and how can I ensure 664 file permissions system wide, no matter what creates the file? UPDATE: I ended up finding a cleaner solution to this on a per-directory basis using ACLs, which I describe here.

• How to verify system using right GPU, after system reset [duplicate]

  - by Antoros

  This question already has an answer here: Is my mobile AMD card being used? 2 answers OS: Windows 8 CPU: Intel® Core™ i7 Processor 3635QM GPU 1 : Intel HD Graphics 4000 GPU 2 : AMD Radeon™ HD 8870M other info: System Spects Problem: im unsure that CCC is using AMD card instead of Intel's, i have encountered several issues since updating to 8.1 and i don't know what to do What happened: Installed 8.1 patch first day After 1 minute of use, BBSOD, windows never loaded again System restore wouldnt recognize 8.0 restore points i did a system reset to windows 8 since the laptop was only 3 weeks old System Broke, it did restore to factory BUT kept the registry almost intact, i had to install almost everything again, since the factory drivers where working with the updated one's registry and several problems CCC Broke too <- What i've already done Installing new drivers on top of old ones didnt work, so i used AMD uninstaller first Uninstalled and Re-installed Intel's HD Graphics Driver Tried to install mobile center, but AMD told me that it wasnt compatible (even if thats the only driver that they provide via their page as seen Here) Tried to use Auto-Detect, couldnt install driver because card was disabled because it didnt have the drivers... (see what they did here?) Had to use a workaround with Samsung Update, the driver didnt appear as download so had to use search and downloaded the driver manually. Now the graphic card appears on device manager and catalyst but as 8800 series (not exact model), and cant check the card with neither dxdiag/GPU-z/HWMonitor when right-clicking on CCC only Intel card appears launching a game and using as "high performance" would speed it up a little but i cant be sure How to verify its working properly? HWMonitor wont show AMD card even when set to high performance Latest GPU-Z wont work because a problem with Intel's, and legacy ones wont either what can I do now? I don't even know if I fixed my problem or not, and i also want to to use Adobe Premier with it, and its locked (the option to run it with the amd card not intels) Edit: now it seems to work, but cant change the setting for adobe Premiere and other programs that i Need to

• Update Grub on Squeeze - Kernel downgrade due VMware Server

  - by vodoo_boot

  I happen to run into various problems regarding grub and kernels. I don't really care about the kernel internas. All I want is VMware server in that dedicated root-server. 1.) What is a bzImage vs. vmlinuz? kaze:~# ls /boot/ System.map-2.6.32-5-amd64 bzImage-2.6.33.2 config-2.6.33.2 initrd.img-2.6.32-5-amd64 System.map-2.6.33.2 bzImage-2.6.35.6 config-2.6.35.6 vmlinuz-2.6.32-5-amd64 System.map-2.6.35.6 config-2.6.32-5-amd64 grub I updated my menu.lst (grub2): timeout 5 default 0 fallback 1 title 2.6.32.5 kernel (hd0,1)/boot/vmlinuz-2.6.32-5-amd64 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.35.6 kernel (hd0,1)/boot//bzImage-2.6.35.6 root=/dev/sda2 panic=60 noapic acpi=off title 2.6.32.3 kernel (hd0,1)/boot//bzImage-2.6.33.2 root=/dev/sda2 panic=60 noapic acpi=off That doesn't do well... I think the vmlinuz file is missing initrd or so. Dunno. In fact I don't give too much about kernel boot voodoo as long as it works. update-grub(2) does not work. Does anybody know what magical trick there is to get the 2.6.32-5 booting? 2.) I thought t follow the Deban wiki.. I cannot get header-files for the installed 35.6 or 33.2 kernel in the repositories. I cannot build foreign headers because they will not match the running kernel. So how does one deal with that situtation? I'd prefer not to have to downgrade the kernel. Thanks for any answers!

• Recent DDE / file open issue with Office 2007 affecting only a few machines, is a Windows Update to blame?

  - by kafka

  All our workstations run Windows 7 Professional 64 bit. It started with one, then another, then another couple of machines having a problem accessing Word files locally and on the network. This doesn't happen on my machine though. Affected users get the error message 'There was a problem sending the command to the program'. I've Googled for solutions, but none of the answers worked. They suggested deleting certain registry keys; unregistering and reregistering the program for DDE; resetting the way that the shell opens .docx programs etc. each to no avail. As it affects local and network shares I believe the problem lies with the clients, and not the server, and I'm starting to suspect that there could have been a recent Windows Update which has caused this. I've tried comparing the updates on my working machine with an affected machine, but I can't immediately see any major differences. Has anyone else recently encountered this problem? What are the best steps to take to further isolate what could be causing this?

• Why am I missing 4GB of RAM on Windows Server 2008 R2 64bit?

  - by Nick G

  I noticed today that a server was very low on memory. It physically has 8GB installed and runs Windows 2008 R2 Standard 64bit. It also hosts 2 virtual machines using HyperV. Server is Dell Poweredge R510. However the host OS reports in task manager that it only has 4GB of RAM, despite actually having 8GB and it being a 64bit OS. Computer properties shows Installed memory: 8.00GB (3.99GB usuable). Why would "usable" be half the real RAM installed under a 64bit OS? Additionally nearly all of the 4GB of visible RAM on the host OS is being used by something without anything showing up in task manager (presumably HyperV as it's allocated 3.6GB to the virtual machines its hosting). However that doesn't explain where the other 4GB has gone which Windows can't even see. Where is my missing 4GB of RAM? Update: Dell OpenManage says this: Total Installed Capacity 8192 MB Total Installed Capacity Available to the OS 4096 MB So looks like Nathan's suggestion of memory mirroring might be correct. I'll have to reboot to check this (I think?) Update 2 OK. So I reboot and I get a message saying "the amount of system memory has changed" (despite not having touched the hardware in a year). Once Windows has booted, all 8GB is visible again. Looks like I probably have a hardware RAM issue (I'll perhaps try reseating it whenever I can chuck everyone off the server next). Thanks for your answers and comments. I was hoping it was going to be the mirrored-RAM option but it seems not - that's not even mentioned in the BIOS.

• Windows 8 preinstall downgrade to Win 7: UEFI problems :/

  - by Tim Flemming

  I have a friend who has a Hp Laptop with UEFI booting. He locked himself out of windows 8 (forgot his password)... so he called me. Well after trying to use the latest version of chntpw in UBCD5.2.6, i came to the conclusion i needed to wipe the drive and install windows 7. A little googling suggested using certain versions of chntpw, but i decided to not waste the time burning endless CDs. Anyway, He agreed to installing Win7 "I hate the big tile thingys". So i attacked with Gparted. Wiped the whole drive. Set flags to boot. Set part table as MBR. However upon trying to install win7, it still claimed i had a GPT style disk. unable to install. the only thing i can think of I'm doing wrong is not changing the bios/UEFI to legacy... My question is, If I enable legacy, somehow get the drive to actually be MBR, and use my X86 DVD, should I be good? Is there some common glitches ppl miss when dealing with GPT/EFI/UEFI? I need answers cuz he now has a blank laptop which I am responsible for. Another question. windows 8 came installed on a GPT disk. SO WHY WHEN I BOOT THE INSTALL DVD DOES IT SAY IT CANT INSTALL TO A GPT STYLE DISK??? WTF??? talk about the bleeding edge man.

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem. EDIT: In the end, nothing really worked, and I got really annoyed with the state of compiz and its support in Debian. Many nVidia driver revisions have passed and I am using Gnome 3 now, so I am accepting the best answers to this question even though the issue was not resolved.

• Is it possible to trace someone using Google during an online exam?

  - by George

  I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?

• Recover windows cached domain password

  - by theguy

  I have a computer from another small organization that works with our school. It was previously joined to another domain from elsewhere. The organization doesn't have an IT person so they didn't think of what they needed to do about the information on the computer before they moved it to our school. The previous user of the computer is no longer with the organization so no information about the password. The computer has information that needs to be accessed and programs so putting the hard drive on another computer and grabbing the information is a no go as I need the computer itself to be working as well. The computer is running Windows Vista Business Edition and is joined to a domain with a cached profile. The admin accounts are disabled by GPO. I've been asked to see if I could recover the password but running ophcrack gave me no hits on the cached profile. I'm not too familiar with password recovery tools that would work on a cached profile from a domain so I'm looking for answers here. Any other suggestions? Preferably something free as we're a small school and an easy to use liveCD solution like ophcrack would be appreciated.

• Create custom launchers in GNOME 3

  - by hochl

  I'm using Debian testing, and I have been switched to GNOME 3 by the Debian update yesterday. I'm not very comfortable with the UI. I wanted to customize everything like I had it with GNOME 2, but I simply couldn't find any way to change preferences like I'm used to. I've digged some, but all answers I could find did not help me achieve my goals. So please, if anyone knows the solution to this I'd be thankful: 1) I want several launchers that launch terminals, with different arguments and different coloring/title. I have searched everything and there seems to be no menu, no right-click, nothing which is standard in any UI I know. How can I create several launchers in this bar on the left side that launch the same application, just with different parameters? With GNOME 2 this was a piece of cake. 2) I want to switch between different terminals using ALT-TAB. Right now, I'm always just getting to the same, already-opened terminal. When I open two terminals by simply creating the second one by issuing xterm &, I still get one Terminal entry with ALT-TAB, and I have to navigate with cursor keys or mouse wheel to select one of the two xterminals. Instead, I want to open a new terminal when I click the quick launch terminal icon from the bar on the left side of the screen and navigate through them like on KDE/GNOME 2/Windows/any reasonable UI. Can this be done? 3) Is there a trick to make bluetooth devices work like on GNOME 2? Right now, my BT keyboard won't pair anymore, which, as you can imagine, makes me pretty angry. and, if anything fails: 4) How can I switch back to GNOME 2 again? :-) Honestly, who did design this? What were they smoking? I feel like I'm not allowed to do anything except start one of any application that has an icon and just with the default parameters. That can't be true, right? I feel massively restrained by this stuff :(

• I want to replace a number with successive numbers, starting at 1 and going up.

  - by Pär-Magnus Green

  I'm aware that this is something people can easily program, but I'm not familiar with those things, so I was hoping there was an easier solution. I've edited a large database of questions, including sorting, and ended up getting all the question ID's mixed up. I'm trying to do this in Notepad++, but any other suggestions are welcome. I'm wondering if there's a way to search for a string (ex. "Question[any number]") and replace the numbers with first 1, then 2, et.c. For clarification, this is how one question looks like: TriviaBot_Questions[3]['Question'][63] = "Acronyms: What does WTT stand for?"; TriviaBot_Questions[3]['Answers'][63] = {"Want To Trade"}; TriviaBot_Questions[3]['Category'][63] = 7; TriviaBot_Questions[3]['Points'][63] = 1; TriviaBot_Questions[3]['Hints'][63] = {}; and the next question, as is now, is not followed by 64. It might be 245 or 1029, and regardless of which number it is, I want it replaced with "previous number + 1", basically.

• What can be done to improve time synchronization on networks with sporadic internet access?

  - by anregen

  I'm looking for advice setting up time servers for a very non-typical network. I support many closed networks that have occasional access to the internet. A network would get access most days for a few hours, but would frequently go 1-3 weeks blacked-out. The computers/servers on this network are mostly *nix-based, but not all the same flavor. The entire network is mobile, so when it connects, it will have very different hops/latency to internet time servers. The servers on the closed network are powered-off frequently (at least daily). Right now, my gut tells me to use NTP (because I hate re-learning all the stuff that someone else already got working pretty well). But I have several issues, and am looking for someone with experience in this type of strange situation. I currently have no solution in place, I'm simply letting the internal clocks drift. This results in errors of ~600s in a majority of networks. I have seen mismatch worse than 10,000s. Is there something "better" than NTP in this situation? I know NTP likes to have very frequent, consistent access to servers that give nearly identical answers. I won't have that. How many internal NTP servers should I configure, so that during periods of internet blackout, I have internal time that is consistent within the closed network? There is no human access. No matter how large the mismatch, the server(s) must attempt to correct itself. Discrete steps are very bad. No matter how large the mismatch, the correction must be "slewed", not "stepped". I understand that this could take many hours to correct.

• map linux drives to windwos 7 for media stream over internet

  - by Ortix92

  I'm trying to map a linux network drive to my windows 7 laptop, however this laptop is not on LAN. At home, I simply use Samba, but this obviously won't work over the internet. I'm trying to avoid VPN, so if there are other solutions, I would like to know about them. The reason I ask is because my university does this as well. We can simply map folders to our computers without VPN connections. I'm not sure what they are running as servers. The main reason is because I want to be able to access my files stored on my home server wherever I go. They are located in the /home/ folder (videos, music and pictures folder). I'm trying to keep my websites and media separate from each other. I wouldn't mind accessing them from a web interface either, but I would like to keep the directory structure intact. I remember having an app like that come with winamp and running it on my windows pc (As the server). Unfortunately it doesn't work for linux. Any ideas on what I could use? Would XBMC be able to help me out with this? I did do some researching but I couldn't find any concrete answers

• Why just splitting an Ethernet cable does not work?

  - by Sin Jeong-hun

  I thought the Ethernet is logically one-line communication bus (for argument's sake, I am excluding hubs). All machines attached in the bus hears the same signals and the machines themselves try to avoid collisions by randomly backing off. http://computer.howstuffworks.com/ethernet6.htm If so, why splitting one Ethernet line from my home router into two and connecting two computers would not work? Why do I have to add a switch to it? *What the Internet said would not work. [4 port home router] ------[one Ethernet cable]-----[simple splitter]======[two computers] *What the Internet said I should do [4 port home router] ------[one Ethernet cable]-----[switch]======[two computers] Is this because of the signal degradation (reduced electric current)? Thank you for all the answers! The reason why I did not just use the two ports of my home router is... The 4-port gigabit router is in my room and I had put a computer in another room (also my room, though). Since wired network is far more reliable and secure, I had bought a long Ethernet cable and and connected the computer to the router. Now I was thinking about adding another computer to that room. I could buy another long Ethernet cable, but then there will be two cables between the rooms. The one line already is a minor annoyance, so I thought if I could share the one line between the two computers in that room. A switch would work, but it requires power and is a little bit pricey. That is why I wondered why it would not work to simply split the physical Ethernet cable. Apparently I do not completely understand how Ethernet and a switch work. I just have some bit of knowledge I heard in my college class.

• IPTABLES syntax help to forward Remote Desktop requests to a VM [CentOS host]

  - by NVRAM

  I've a VM running MSWindows XP hosted on my CentOS 5.4 machine. I can rdesktop into it from the hosting machine and work just fine using the private ddress (192.168.122.65), but I now need to allow Remote Desktop access from other computers (not just the machine hosting the VM). [Edit] I only need to allow access for a day or so, so don't want to add a NIC (for XP activation reasons). Could someone help me with the iptables syntax? The VM is on a private/virtual network: 192.168.122.65 and my CentOS machine is on a physical network, at 10.1.3.38 (and 192.168.122.1 as the GW for the virtual net). I found this question, but none of the answers seemed to work and I'm a bit timid at blindly trying variations. My FORWARD rules are as listed. Thanks in advance. # iptables -L FORWARD Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable RH-Firewall-1-INPUT all -- anywhere anywhere [Edit] If I do play "blindly" is there a simple way to reset the settings on CentOS (a la service network restart)?

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• Laptop seemingly randomly "freezes" to the point of no longer executing applications

  - by Aierou

  After upgrading to Windows 8 pro on my Samsung Series 7 Chronos NP700Z5C-S04US (may be relevant, I'm not sure), my computer began to stop allowing the execution of any service or application, as well as discontinuing the update of the clock until a hard shutdown was performed. This seems to occur randomly after periods of inactivity and I've no idea the cause. These are measures I have already taken in order to attempt to stop this: -Obviously Googling potential answers to this problem -Updating all drivers -Researching all events that have occurred around the time of the failure to respond (with no results) -I tried applying "bcdedit /set disabledynamictick no" which was a hotfix for what seemed to be the same error but was not. Here is some more, potentially related, information about the error: -No BSOD (actually, I haven't at all experienced a BSOD with Windows 8) -Computer seems to have a problem shutting down/restarting most of the time (Hangs at the point where it should completely turn off) -New sound instances are not able to play, but previously loaded containers function properly -As mentioned before, the clock freezes at the time of the error -USB devices function properly -Servers that I was running fail to respond on my end, but stay online. If you require more information, please request it specifically and I will be happy to oblige. Thanks.

• How to make Firefox file associations consistent with Ubuntu file associations?

  - by wbharding

  This seems to be a pretty commonly Google question, but one for which there are no answers. http://www.linuxquestions.org/questions/linux-software-2/firefox-download-mime-types-378902 http://www.birkit.com/content/kubuntu-linux/internet/firefox/fix-file-associations-in-firefox.html Being three links amongst the many. The gist of what I want to accomplish is to have Firefox understand the file associations I download without me having to manually map all of them myself. Gnome knows the file extensions, so I would have expected that Firefox could just use the already-known file mappings there to open the right stuff (as I presume Chrome does). But it doesn't. At least not for me, using Firefox 4, and not by default. When I click on a downloaded file right now, Firefox always has to ask me what application should be used to open the file. A handful of Google results tell me that I can reassociate my file extensions by deleting ~/.mozilla/firefox/[profile name]/mimeTypes.rdf, but while deleting that file does in fact result in a new mimeTypes file being generated, the new mimeTypes is just as barren as the old one had been. Based on the amount of unanswered Qs on the Googlesphere, I know this is a very common problem for Ubuntu users, but it seems to be one for which nobody has chimed in with a good solution. Maybe Superuser can finally be the panacea for us all?

• How do I tell Windows to use 802.11 in preference to 3G?

  - by Jon Skeet

  I have a Samsung NC-10 netbook which I take to work every day. Most of the time I use it just on the train/bus, but I also use it at work and home. It has a built-in 3G card which I want to use when travelling, but I'd prefer to use wifi when I'm at work or home, for obvious reasons. Unfortunately, if the 3G connection is up, Windows appears to use that in preference to wifi. Starting up and shutting down the 3G modem is a bit of a pain - it's not hard as such, just a bit inconvenient. Ideally I'd like it to always be up, and even have the connection itself up all the time, but without routing traffic through it if there's a wifi connection up. This is what my Android phone does, for example. Is there somewhere in Windows which lets me express an ordering for network interfaces? I suspect the routing table may be relevant, but it's a bit of a pain to mess around with. I'd really expect there to be a simple GUI way of setting this up - after all, it would equally be useful when dealing with wired vs wifi connections. I'm currently using Windows XP Home, but Windows 7 answers would also be useful as I'll be migrating soon.

• Best SSD tweaks for Windows 7

  - by Nick Berardi

  I have seen many articles about tweaking an SSD, but many of them seem outdated, or too broad (read all Windows XP, Vista, and Windows 7 general tweaks). And I know that Windows 7 has been specifically tweaked for SSD by the Windows team, so I don't want to do something that was written for Windows XP in mind and end up circumventing something the Windows team has specifically designed in to Windows 7. So my question is what are the best SSD tweaks for Windows 7 that you have found to get the performance out of your drive? I hope to make a comprehensive list in the answers below so there won't be so much disinformation in the forums about what to do and what not to do. Here are a few that I see posted up on the forums alot, and some questions to get the discussion started: Disabling Superfetch. Yes or No Disabling Page File or limiting it to a really small size such as 500 MB. Disabling Indexing. Yes or No Disabling Defragmenting. Yes or No What are your thoughts do you have any that have worked for you? When providing an answer please do your best to back it up with a reason and possibly some documentation from MSDN, TechNet, or another credible source.

• How to set up Windows 7 Professional as a NAS

  - by Enyalius

  I searched and didn't find any answers, so please forgive me if this is a repeat. Anyway, I have an older computer that I'm using as an HTPC, and I was hoping that I could use it as a NAS/multimedia server, as well. My primary uses would include accessing content on my PS3 (same LAN), accessing content from other computers on my home network and (if I can) accessing content from my Android phone over the internet. I have used SubSonic to stream music to my Android phone and other computers before, but I would really like to find a way to do this natively if possible. I know that I can buy external hard disk cases that can plug in the USB port of my router, that I can get a Drobo or other network storage solution, but I would really just rather not spend the money (especially considering that I already have a computer that I should be able to use). Hardware involved: Apple AirPort Extreme base station router (most recent revision) Home Theater Personal Computer: Core 2 Duo @ 2.4GHz, 8GB DDR2 RAM, ~3.5TB hard drive space Sony Playstaiton 3 Thin 120GB HTC Thunderbolt (I have 4G coverage) rooted and running Android 2.2.1 Various Apple laptops Various Windows 7 desktops/laptops Thanks in advance! Note- I have looked at open source NAS software but I would like to preserve the Windows Media Center functionality in Windows 7, so other NAS software is not an option for me currently. .

• How can see what processes makes my server slow?

  - by Steven

  All my websites on my server are extremely slow or not loading at all. Even server admin (Plesk) will not load some times. There's been no changes to the sites for the last coupple of months. How can I see what processes is making my server slow? My environment looks like this: Server: VPS running Linux 2.8.x OS: Centos 5 Manage interface: Plesk 9.x Memmory: 1024MB CPU: 2.2GHz My websites run on PHP and MySQL. I finally managed to telnet (Putty + SSH) in to my server. Running top did not show any processes using more than max 2% CPU and none were using exesive memmory. I also got a friend to install a program that checks the core files, and all seemed fine. So I'm leaning towards network issues or some other server malfunction. But I'm not able to find out what can be wrong. Here are some answers to Sean Kimball: I don't run mail services on my server yet There are noe specific bandwidth peaks. Prefork looks like this <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 256 MaxClients 256 MaxRequestsPerChild 4000 </IfModule> Not sure what you mean with DNS question. But I think it's up and running. There are no processes running wild Where can I find avarage load? Telnet is disabled and I have to log in using SSH :)

• Cannot install windows. Compaq Presario CQ62

  - by Matthew

  I bought a used Compaq Presario CQ62 for cheap, and went to install windows on it. I formatted the partition and went to install when I got this error.... Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error code: 0x80070017 I have used this disk before with no problems, but internet searching suggested I burn one at 2x speed because that helps for some reason... I'm burning one now, but my question is, why would I get this error, OTHER than the disc being bad? I'm pretty certain this one isn't as I have used it before... (ok so the slowly burned cd (using imgburn) didn't work either so it's DEFINITELY not the disc) Thanks in advanced for any answers Also I took one stick of ram out because internet searching also suggested that, but it didn't make a difference. Also I ran memory and hard drive checks and they passed fine. Also I reset the motherboard options to default What could it be!? Help I'm completely stumped...

• Exchange on SBS2003 not receiving mail, but sending via telnet works

  - by YDdraigLas

  Last week we had a problem on our SBS2003 server where our external connection dropped out and I was only able to restore it by running netsh winsock reset catalog and netsh int ip reset. Thinking all was well, I went home for the weekend and came in today to find that we haven't received any external emails since before the original problems occurred. There are plenty of examples of this on the internet, usually to do with a firewall issue, but the odd thing here is that when I connect using telnet I can send an email and it goes straight through and into my inbox. When I send an email from Gmail or Hotmail nothing comes through at all. Internal emails are also unaffected, as are outgoing emails. There have also been a couple of emails that have come through for other users, both out-of-office replies, if that's relevant. I've run the CEICW several times, checked all the NIC settings, but no joy. Before I give up trying to fix this and reinstall the whole server, has anyone come across this problem before? I have only found fleeting references to this in previous searches and no real answers. Any advice gratefully received.
