• Dedicated server given, how to start?

  - by eduardito

  Hello, I've been given a dedicated server. Unfortunately, I have no idea what to do / how to manage it. I have background in many fields on Computer Science but never got to focus on networking, server management, etc. What I'm asking is for recommended books, Basically, I would like to be able to be proficient and understand well how to manage domain names, zones, setting up mail servers, being able to install easily any web server, and such. Everything needed for proper server management through the shell. I will probably stick with Parallels, or Cpanel for a bit. But I dislike those, especially how it add a lot of intruding user accounts and configs on the file system. Thank you

• What is Slotted and pure aloha?

  - by caspert

  So I am having a really hard time understanding slotted and pure aloha. I have understood CSMA/CD fairly well, but that is it. I have the book: Computer networking - a top down approach, but I find the explanation very cryptic and hard to understand. Wikipedia did not help me. Does anyone have a brief "aloha for dummies" explanation? or perhaps a video tutorial? I think I need something visual. I don't need to be able to create the protocol, I just need a general understanding of it.

• Which type of memory is faster than average for server use?

  - by Tony_Henrich

  I am building a server computer which will be used for SQL Server and I am planning to use like 32G+ of RAM and putting the databases in memory. (I know all about data loss issues when power is gone). I haven't been up to date with the new types of memory sticks out there. What kind of memory should I get which is faster than average and not very expensive? I am buying a lot of ram so I am looking for memory that's above average but below high end if high end is very expensive. (I will be using Windows Server 2008 R2 Standard or Windows HPC Server 2008 R2)

• Why my USB mouse get suspended after 3 seconds of inactivity?

  - by Vi.

  Mouse's bottom LED goes off after 3 seconds after connection and cursor movements and wheel stops. Pressing any button, reconnecting or resetting USB device resumes it for another 3 seconds (when resumed by pressing button, this event does no go to X). This happens when using any of USB ports. This mouse works well with other computer with Linux. It was working well before. Why can it happen? How to fix it? Update: It happens only if laptop is on battery. Answer: this is caused by powersaving done by laptop-mode-tools. To temporary turn off powersaving one can use for i in /sys/bus/usb/devices/*/power/control; do echo on > $i; done

• How to join a Windows Domain and Map Network Drives?

  - by AgainstClint

  I just installed the current build for Ubuntu on a partition for my work computer. I am a novice when it comes to Linux/Ubuntu, which is why I installed it along side windows. I want to learn how to operate and use Ubuntu much more than I do now, so I figured installing it and trying to do day to day functions here would be a "Thrown into the pool with sharks" way to do it, and I like that way. I did however have a few questions: We are on a Domain in Windows, is there any way to join that domain using the Ubuntu partition? We Also have 16 mapped network drives. I don't actually need ALL of them mapped for Ubuntu, but is there a way to Map at least one of them to see/use here in Ubuntu. Outlook Corporate email, how can I sign in/use it while...well, you get the idea. As I said earlier, I am VERY new to Ubuntu, i've only played around with it a bit at home and never at the office. If you could simplify it down for me a bit, that would be great.

• Unable to run Django on Mac OS X

  - by cybervaldez

  I'm working with a Django project on my Mac (running Leopard) and I want to show it to my team. I've already passed the neccessary port forwards from my router to my Mac's LAN IP address but it doesn't work. I've also tried running the XAMPP server since that always worked with my Windows XP computer but it still doesn't work. Whenever I type my > it's showing a Page Load Error. Is this possibly an issue with an Mac OS X configuration that I need to setup first to allow my port forwards to get in? It's my first time to do this with Mac, perhaps I need to configure something else in network preferences?

• Desktop runs very slick, animations are all fast and flawless. Moving windows around, however, is very laggy. Why?

  - by Muu

  This isn't a question about Ubuntu being laggy in general - not at all, in fact, it's very slick and fast for me. Clicking the "Workspace Switcher" in the dock performs the animation immediately and very smoothly. Switching between workspaces with the arrow keys - again, flawlessly. My computer has a resolution of 2560x1440 on a 27" display (no, not an Apple product - though my monitor has the same panel that Apple use in their cinema displays). It's powered by an Nvidia GeForce GTX 470 - easily enough to handle it - and an Intel i3. Hardware is not the issue. I am running Ubuntu 11.10 (upgraded from 11.04). I had the same issue in 11.04. I'm running the "NVIDIA accelerated graphics driver (post-release updates) (version current-updates)" from the additional drivers dialogue. Two drivers have been suggested to me via that dialogue and I've tried both - same effect with each. The driver is "activated and currently in use". Any other information required, let me know and I'll post it. I'm a programmer who works with Linux daily (both as a job and as an interest) so technical instructions are fine. I've noticed that Compiz uses a lot of CPU when moving windows around and it's memory usage is relatively high (though possibly expected for Compiz): 1671 user 20 0 478m 286m 33m S 1 7.3 12:44.05 compiz And one more thing - occasionally moving windows around is fast. But it only happens when all applications are closed, and even then it sometimes doesn't. Something must be interfering, but what? I'll try and find out but in the meantime, any suggestions are much appreciated :-)

• Friend wants to return an iMac with Lion in it. How does he remove his personal info / do clean install?

  - by fakaff

  I have a Mac, but not Lion, and it seems like a lot has changed with Lion. He wants to return the computer. I told him doing a clean install will make it like new, but he says you can't download a bootable disk image from the appstore to do this. He doesn't want to torrent it because he thinks the store will know it's a ripped version. Is there a way for him to remove his Admin account so that none of his personal info remians on the machine?

• Man pages in Linux

  - by Ayos

  I don't seem to have all the man pages that I need. For example, my college computers (running Fedora 14) have man pages for ASCII, all the standard C libraries (stdlib.h, stdio.h) and so on and so forth. I wish to "install" these pages, after looking up on the Internet I couldn't really find anything that made sense. How can I get, say, the man-page of ASCII (I know it's not really a command or a daemon or anything like that, but typing man ASCII on the college computer gets me a page with the ASCII value table + a little more information). I don't want to keep using the Internet for looking up man pages every time I need to look up a function, function prototype or the ASCII table or something like that.

• How do I restore a Windows 8 iso image to a USB disk in OS X?

  - by duci9y

  I am on OS X and have a Windows 8 Consumer Preview x64 image. My computer doesn’t have a CD drive (MacBook Air). I have a 4 GB USB drive. I want to restore that image to the USB drive. There are many tools to do that on Windows, but I can’t finger out how to do it in OS X. Please note that I can’t run a VM, as my Air is a limited use machine. What I’ve tried: Simply restore to USB. Convert the image to img and use dd. These don’t work. How do I go about doing this?

• /etc/hosts in Windows 8.1 doesnt work like in Windows 7 [on hold]

  - by user225438

  Last time when i installed Win7, i configured it to block some netbios names in LAN with hosts file. Something like this: 192.168.0.10 computer_name 192.168.0.10 computer_IP where 192.168.0.10 some ip-address in network, where user need to login to access it. So, when user trying to access computer_name via \\computer_name, he will redirect to 192.168.0.10 rather then going to computer_name. In Windows 8.1 I can't do this trick. I tried to disable Windows Defender, flushed DNS, nbtstat -R. Nothing works. When I pinging computer_name, IP address returning 192.168.0.10, but when I accessing it via explorer (\\computer_name\d$), it opening computer partitions. In Win7, when I trying to access \\computer_name, its trying to open 192.168.0.10 one. Maybe its not the best solution to do this, but it works in Windows 7.

• SVNNotify Where is it? how do I find it?

  - by John Isaacks

  I am on ubuntu. ok first of all I am running a post-commit script. I need the path to svnnotify to run it. The path the turotial I am reading has it as /usr/local/bin/svnnotify but nothing is in that location on my computer. I tried it anyways and I get something like: Warning post-commit hook failed: not found so I think I need to replace /usr/local/bin/svnnotify with the correct path to svnnotify. Well I do a search (Places>Search for Files) for svnnotify and nothing comes up. I know svnnotify is installed becuase if I open a command line and run svnnotify it tells me I am missing the required path argument. So how can it be installed if its not in the file system anywhere? I don't really know how linux works, its very new to me, so I am confused. Is there something I am missing?

• Windows 7 Laptop, cursor jumping after typing the letters "y" or "t" [closed]

  - by Dave K

  My wife has an HP laptop running windows 7. She has a very frustrating problem when typing: in some, but not all cases, typing the letter's "y" or "t" will cause the cursor to jump back a few lines or some number of words. The result is that she ends up typing over whatever it was that she was working on. (as a matter of fact, I just experienced this while typing this question on her computer with the phrase: "typing the letter..." above.) I've installed the latest drivers for her touchpad from Synaptic and disabled tap touching and gesture features to rule out simple unintended mouse clicks. Still the "y" and "t" keys continue to cause problems.

• Setting a mapped drive in Virtual hosts causes apache to not start

  - by darksoulsong

  I´m trying to set a virtual host on my windows 7 machine. The folder I want to point to is located on a centOS machine and the folder path is Z:\Websites\Online\MyClient\Site. But something strange happens when I set the document root like this: DocumentRoot "Z:\Websites\Online\MyClient\Site" Apache do not restarts after that. When I take a look at the log, there is an error pointing to that line, where I added the path to the folder: Syntax error on line 48 of C:/Program Files/Zend/Apache2/conf/extra/httpd-vhosts.conf: DocumentRoot must be a directory. There must be a way to make it work like this, by setting an Apache Installation on a machine and pointing it to a folder located on another computer, right? My hosts file is set like this: 172.17.10.1\Data\Websites\Online\MyClient\Site MyClient.local ANY HELP would be VERY appreciated.

• Will readyboost speed up a secondary partion or harddrive?

  - by Sebastian

  I'm building a new computer and plan on using a few spare USB sticks with readyboost to cache disk writes. I'll be running Windows 7 Enterprise SP1 x64 I have a single 2 TB disk, and plan to make a partition for windows (100 GB) and use the rest for data. I know Readyboost will work nicely for the C drive, but am unable to find any information on whether it will accelerate a second drive or partition. Just to clarify, I'm NOT trying to use the harddrive instead of the usb sticks. I'm trying to speed up the second partition using the USB sticks So, will readyboost work for a secondary partion or harddrive?

  i need help on the following issue. We have Dell T1650 PCs with 2 nvidia graphic adapters / Windows 7 and 4 attached monitors.

• How can I convince my boss that ANSI C is inadequate for our new project?

  - by justifiably cowardly

  A few months ago, we started developing an app to control an in-house developed test equipment and record a set of measurements. It should have a simple UI, and would likely require threads due to the continuous recording that must take place. This application will be used for a few years, and shall be maintained by a number of computer science students during this period. Our boss graduated some 30 years ago (not to be taken as an offense; I have more than half that time on my back too) and has mandated that we develop this application in ANSI C. The rationale is that he is the only one that will be around the entire time, and therefore he must be able to understand what we are doing. He also ruled that we should use no abstract data types; he even gave us a list with the name of the global variables (sigh) he wants us to use. I actually tried that approach for a while, but it was really slowing me down to make sure that all pointer operations were safe and all strings had the correct size. Additionally, the number of lines of code that actually related to the problem in hand was a only small fraction of our code base. After a few days, I scrapped the entire thing and started anew using C#. Our boss has already seen the program running and he likes the way it works, but he doesn't know that it's written in another language. Next week the two of us will meet to go over the source code, so that he "will know how to maintain it". I am sort of scared, and I would like to hear from you guys what arguments I could use to support my decision. Cowardly yours,

• Monitor does not turn on until reset

  - by eggonlegs

  I have a system with an ATI 4870 hooked up to a Samsung P2350 using DVI. My motherboard is a GA-EP45 DS4P with the latest BIOS. The situation is: I turn on my PC (with the power switch) I get a blank screen I hit reset and the PC boots up normally, i.e. the monitor turns on and This has been the case for a couple of months (Was away for a while, came back and it was the same case). I was hoping the situation would somehow fix itself but alas, nothing. I have tried numerous settings in the BIOS (Combinations of different settings of the ACPI and power saving options) and have tried different cables. Has anyone experienced this before? I don't know where to go from here. It is pretty infuriating because it means I can't put my computer to sleep, as the monitor won't come on. Any help is appreciated. Thanks

• Firefox on Windows 7 became an "always top" window

  - by Firebear

  I am using Mozilla Firefox 7.0.1 on a Windows 7 computer (home basic). I usually keep the browser window opened for a long periods of time, like three to four weeks, and I have many tabs opened in the window, like 300 to 900. Recently all of the sudden the Firefox window became "always top" window. I can minimize it, but when it is maximized, no other window can be displayed in front of it, only behind it. This is very inconvenient for me. Is there any fix that I can apply without restarting the Firefox window? Thank you.

I can access openERP when I'm connected to the network of my office but not when I'm outside my office's network. What am I missing? my computer's ip address starts with 192... Do I have to first up the router's ip address and then my server's ip address to get to my server from the outside? what should I type in my internet browser? I've looked all day yesterday.

• How Can I Speed Up Terminal.app or iTerm on Mac OSX?

  - by pmaiorana

  Every time I launch either iTerm or Terminal after not using it for a few hours, it takes anywhere from 10-20 seconds to return a prompt. The screen is blank, and although I can type I can't actually run any commands. If I quit either application, subsequent launches (if done relatively soon thereafter) are quite fast. The slowness only seems to occur if the app wasn't running for a few hours. I'm running OSX 10.5.7 on a MacBookPro. I have the exact same setup on another computer, with no slow downs. Any ideas how to speed things up again?
