  • Adding MX records to DNS

    - by Teddy
    Let's say I have a computer A which is running postfix, computer B is running tinydns. On domain project.domain.com I'm running httpd server and other server with DNS (tinydns) have entries like =project.domain.com:1.2.3.4:86400 and +project.domain.com:1.2.3.4:86400 where 1.2.3.4 is correct addres for server which runs httpd server. I also have a postfix mail server on 1.2.3.5 which I'd like to work with this domain (project.domain.com). I'm afraid that if I add another alias like +project.domain.com:1.2.3.5:86400 to tinydns configuration - it could break. How that entry should look like? Thank you for any hints.

  • Can't save screen resolution setting.

    - by Searock
    Hi, My screen resolution in windows and previous version of Ubuntu (9.04) was 1152 x 864. But in Ubuntu 10.04 it gives me an option of 1024 x 786 and 1360 x 786. I have some how managed to add 1152x684 resolution by using xrandr command. searock@searock-desktop:~$ cvt 1152 864 1152x864 59.96 Hz (CVT 1.00M3) hsync: 53.78 kHz; pclk: 81.75 MHz Modeline "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync searock@searock-desktop:~$ xrandr --newmode "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync searock@searock-desktop:~$ xrandr --addmode S-video 1152x864 xrandr: cannot find output "S-video" searock@searock-desktop:~$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1360x768 59.8 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 59.9 1152x864_60.00 (0x124) 81.0MHz h: width 1152 start 1216 end 1336 total 1520 skew 0 clock 53.3KHz v: height 864 start 867 end 871 total 897 clock 59.4Hz searock@searock-desktop:~$ xrandr --addmode VGA1 1152x864_60.00 But the problem is when ever I restart my computer I get this message. Could not apply the stored configuration for the monitors. Could not find a suitable configuration of screens. And then it comes back to 1024 x 786 My graphic card details : Intel(R) 82945G Express Chipset Family. Is there any way I can fix this once for all ? Thanks. Edit 1 : rumtscho has suggested me to modify xorg.conf file. But I am not sure what HorizSync means? is it Horizontal frequency ? My monitor model is Acer v173. Here's my specification. So what should be HorizSync and VertRefresh ? Edit 2 : I have edited my Xorg.conf file as follows : Section "Monitor" Identifier "Configured Monitor" HorizSync 30-80 VertRefresh 55-75 EndSection then I added the resolution and restarted my computer and still I am facing the same problem. Is there something that I am missing? Edit 3 : For now I have edited /etc/gdm/Init/Default(gdm startup scripts) to include following xrandr commands, just below line initctl -q emit login-session-start DISPLAY_MANAGER=gdm xrandr --newmode "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync xrandr --addmode VGA1 1152x864_60.00<br/> xrandr -s 1152x864_60.00 This has solved my problem, but this commands have increased my computer's boot time. I think I will have to edit xorg file properly. Edit 4 : Instead of adding this files to gdm startup scripts I have created a shell script and added it to startup (System - Preference - Startup Applications) #!/bin/bash xrandr --newmode "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync xrandr --addmode VGA1 1152x864_60.00 xrandr -s 1152x864_60.00 And don't forget to add execution rights. (Right Click - Properties - Permission - Allow executing file as program)

  • Is learning how to use C (or C++) a requirement in order to be a good (excellent) programmer?

    - by blueberryfields
    When I first started to learn how to program, real programmers could write assembly in their sleep. Any serious schooling in computer science would include a hefty bit of training and practice in programming using assembly. That has since changed, to the point where I see Computer Science degrees with assembly, if included at all, is relegated to one assignment, and one chapter, for a total of two weeks' work out of 4 years' schooling. C/C++ programming seems to have followed a similar path. I'm no longer surprised to interview university graduates who have not spent more than two weeks programming in C++, and have only read of C in a book somewhere. While the most serious CS degrees still seem to include significant time learning and using one or both of the languages, the trend is clearly towards less enforced C/C++ in school. It's clearly possible to make a career producing good work without ever reading or writing a single line of C or C++ code. Given all of that, is learning the two languages worth the effort? Are they at all required to excel? (beyond the obvious, non-language specific advice, such as "a good selection of languages is probably important for a comprehensive education", and "it's probably a good idea to keep trying out and learning new languages throughout a programmers' career, just to stretch the gray cells")

  • Multilingual website without language component in the URL

    - by user359650
    I'm working on a website for Canada which will have French and English versions. For SEO purposes, I would like to avoid using any language tag in URLs because I believe it will have more impact (e.g. example.ca/products better than en.example.ca/products or example.ca/en/products). I believe this is technically possible because the2 languages are sufficiently different that the URLs won't be conflicting with one another (e.g. if you want a "product" page, it will be /products in English, and /produits in French so you know which language the URL is about). Since Google (and most likely others) doesn't rely on the URL (nor HTML tags) to determine the content language I don't see any problems with search engines. To make this possible I've thought about using a cookie distinct from the session cookie (e.g. example.org_language) with long term expiry (e.g. N years) that will memorize the language chosen by the user. That way when people visit the website with a new browser session, they get served the proper language. I have already given up on users being able to switch one page from English to French: when people will chose English or French from the menu they will be redirected to the corresponding version of the home page. Do you foresee any problems with not using a language component in the URL (whether domain or path)? (as long as one makes sure URLS don't conflict).

  • Windows file sharing connects over WiFi instead of LAN

    - by zacaj
    I have a laptop and a desktop computer, and I need to sync lots of files to the laptop and back whenever I go on a trip, etc. I've got a LAN cable connected into an extra port on the desktop that I plug into the laptop so I can get gigabit file transfers instead of wireless G. They connect fine. If I do an FTP transfer, for instance, using the LAN IP addresses, it goes at ~40MB/s, as it should. However when I copy files using explorer and native windows file sharing it detects the other computer by name, not IP (eg \\DESKTOP-PC\ instead of \\192.168.0.100\) and always connects to it by its wireless IP address instead of the faster LAN address. Both computers are running Windows 7. I have tried editing the priorities of the adapters in Advanced Settings and putting the LAN adapters above the wifi ones, but this didn't have any effect

  • Accessing the Internet via browser

    - by ucas
    I am on Windows 7 and using Firefox browser. I am using WiFi, but since the morning I cannot access the Internet via the browsers (Firefox, Chrome, or IE). The laptop shows there is Internet connection, Skype is online, but I can't reach the Internet. Then I launched Tor application which creates secure channel and provides its Firefox browser. Well, I can now access the Internet over that browser. So, what might be the problem causing this malfunction? The error: The connection has timed out The server at mail.google.com is taking too long to respond. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

  • SQL Server backup/restore error: The Media Family on Device is Incorrectly Formed.

    - by Chris
    Basically, I'm having this issue: http://www.sqlcoffee.com/Troubleshooting047.htm What I'm doing is running a script I found online (http://pastebin.com/3n0ZfybL) to do a full backup, then rar'ing up the file and moving it to my computer. The CRC of the backup file inside the rar is correct on both computers, so there is no problem with data being corrupted when I transfer it. But then I go and try to restore the database on my dev computer here and I get the errors "sql server cannot process this media family" ... "msg 3013". Why is this happening? I'd test out the backup on the server I'm getting it from, but it's a production server.

  • How can Highscores be more meaningful and engaging?

    - by Anselm Eickhoff
    I'm developing a casual Android game in which the player's success can very easily be represented by a number (I'm not more specific because I'm interested in the topic in general). Although I myself am not a highscore person at all, I was thinking of implementing a highscore for that game, but I see at least 2 problems in the classical leaderboard approach: very soon the highscore will be dominated by hardcore players, leaving no chance for beginners, who are then frustrated. This is very severe especially in casual games. there is no direct reward for being a loyal player who plays the game over and over again My current idea is to "reset" the highscore every 24 hours (for example) and each day nominate the "player of the day" who then gets a "star". Then there would be some kind of meta-highscore of players with the most stars. That way even beginners might have a chance to be "player of the day" once and continued or repeated play is rewarded much more. The idea is still very rough and there are many problems in the details and the technical implementation but I have a feeling it is a step in the right direction. Do you have creative and new ideas on how to implement highscores? Which games are doing this well / what types of highscores do you find most engaging?

  • Ubuntu stops using Nvidia driver after kernel upgrade

    - by Daniel
    Just updated and restarted, Ubuntu's doesn't display correctly. After restart, the desktop now looks like this. I've temporarily switched to the Nouveau driver. The update history reveals the kernel was updated, amongst many things; and the following were installed: linux-image-3.5.0-19-generic (3.5.0-19.30) linux-image-extra-3.5.0-19-generic (3.5.0-19.30) I've encountered this type of problem quite recently, so I decided to reapply the same steps, to solve the problem, as follows: sudo apt-get install linux-headers-3.5.0-19 sudo apt-get install linux-headers-3.5.0-19-generic sudo depmod -a sudo modprobe nvidia sudo /etc/init.d/*dm restart When installing linux-headers-3.5.0-19-generic, I get an error, message from terminal as follows: Setting up linux-headers-3.5.0-19-generic (3.5.0-19.30) ... Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 3.5.0-19-generic /boot/vmlinuz-3.5.0-19-generic Error! Problems with depmod detected. Automatically uninstalling this module. DKMS: Install Failed (depmod problems). Module rolled back to built state. However, I ignored the above error and continued the steps with sudo depmod -a, installed nvidia-current, then did sudo modprobe nvidia, which yielded the following error: FATAL: Error inserting nvidia_current (/lib/modules/3.5.0-19-generic/updates/dkms/nvidia_current.ko): No such device Upon restart, the Nvidia driver now works! BTW, do those error messages imply I broke something? Just curious, cause I don't want to get happy I've fixed it, then it stops working later on. The system is Dell XPS-L702X, with NVIDIA GeForce GT 555M, and 17" screen.

  • Netbeans: Install/Activate/Uninstall/Deactivate plugins buttons disabled

    - by Josh
    I recently installed Netbeans 6.9 on a new computer. I went to install the NB Android plugin, which I have on another computer, but I found most of the functionality of the plugins window disabled. The install, uninstall, activate, and deactivate buttons are grayed out. I have included images at the bottom. This hasn't happened to me before, and searching Google hasn't turned up anything useful. I thought it might have been a permission problem so I tried running Netbeans with gksudo but that didn't help. I also thought it might have been something wonky with the Ubuntu Software Center install, so I uninstalled that one, and downloaded Netbeans from the main site and I installed it in my home directory, but it does the same thing. I'm running Xubuntu 10.10 and Netbeans 6.9.1 Available Plugins Tab It won't let me add more than one hyperlink due to a lack of reputation. Installed Tab - http + i.imgur.com/Nhqi4.png

  • Steam app and age verification issue

    - by TronicZomB
    I have OSX 10.9.4 with the Steam App (API v016 and package versions 1407966480) installed. When I would visit game pages that required age verification, my birthday would be filled in due to being logged in and I would just click OK to move past. Now the age verification shows up with January 1st, 2014 each time and it will not let me change the date. The drop down menus just show up blank. I have tried to log out of my computer, log out of Steam, restart Steam, restart my computer, and reinstall Steam. Nothing has worked and it continues to have this issue. When I visit the Steam website, the age verification drop downs work just fine. What is causing this issue? And/or how can I fix this issue?

  • How to create a separated network to customers only?

    - by Valter Henrique
    I work in a company where we have a network ethernet and wi-fi, we would like to create a network where our customers could access our network but don't have access to our computer network. This access would be internet only, nothing more. The customers will not see our computers and the files that we share in our network. I have two routers, how can I do this ? A Cisco Linksys Wireless-N Broadband Router WRT160N V3 and a Netgear Wireless G Router WGR614 v9 and about firewalls there´s only windows firewalls in each computer by default.

  • Website loading until initial script finishes

    - by wardy277
    Hi, i have a highly used server (running plesk). I have some long scripts that take a while to process (huge mysql database). I have found then in 1 browser, i run the script and while it is loading i cannot view any other parts of the site until the script finishes, it seems that all the requests go off, but they don't get served until the initial script finishes. i thought this may be a server wide issue, but it is not. If i use another computer i can view the site fine, even on the same computer with a different browser i can navigate fine, while the script still loads. I think it much limit the number of requests per session. Is this correct? is there any way to configure this to allow for 2-3 other requests per session? It is really bad that when i am on the phone to a client, i have just run a long report, but cannot use the site or follow what they are saying until the page has loaded? Chris

  • Folder Redirection won't load on Windows 7 Machine in Windows 2008 R2 Network

    - by leeand00
    Okay so redirected profiles don't load exactly, but the computer is joined to the network and it won't display any of the users files on their desktop that are in their redirected profile. I know this because we have a Terminal Server and when the user logs in there, her files appear. I checked the users' profile in Active Directory Users and Computers and compared it with a working users profile. When that didn't turn up any differences, I looked at her computer and found that on the Dial-in tab the Network Access Permission wasn't set to Control access through NPS Network Policy like it was on the other machines on the network; so I selected it, ran gpupdate /force on her machine and rebooted. This did not fix the issue. Is there anything else that could be preventing the redirected files on the users desktop from showing up when the user logs in?

  • Security of BitLocker with no PIN from WinPE?

    - by Scott Bussinger
    Say you have a computer with the system drive encrypted by BitLocker and you're not using a PIN so the computer will boot up unattended. What happens if an attacker boots the system up into the Windows Preinstallation Environment? Will they have access to the encrypted drive? Does it change if you have a TPM vs. using only a USB startup key? What I'm trying to determine is whether the TPM / USB startup key is usable without booting from the original operating system. In other words, if you're using a USB startup key and the machine is rebooted normally then the data would still be protected unless an attacker was able to log in. But what if the hacker just boots the server into a Windows Preinstallation Environment with the USB startup key plugged in? Would they then have access to the data? Or would that require the recovery key? Ideally the recovery key would be required when booted like this, but I haven't seen this documented anywhere.

  • Make Windows Task Scheduler alert me on fail

    - by acidzombie24
    I have an automated script that pulls backups from my website to my local computer. Once my server was down, another time i accidentally move my script. How do i make Windows Task Scheduler tell me with the script fails (or doesnt run/not found)? I dont care if a prompt comes up, an email or something that appears on my desktop. I want to be notified if something goes wrong. On my server crontab emails me about errors which is great. I want something like that on my windows 7 local computer.

  • Pros and Cons between learning to program on Windows and Linux and Macs

    - by Amumu
    I have been studying IT for 2 years and I'm going to graduate soon in this year (if everything goes well). I think it's time for me to choose a path to specialized into some fields of this large industry. Personally, I want to be a game programmer. But to be a game programmer, surely I have to invest my time to study Windows Programming, then DirectX and other programming techniques related to game. On the other hand, Linux seems promising as well. I am not sure about Game Programming on for it, but it seems become an expert for this OS, and by expert it's not about using the OS to become an administrator, but can do further than that, such as understand the OS to its essence and can produce applications for it. However, there's some obstacles in my view for this development path. Many of my friends think that Linux is based on free and open source, and if you follow it, as its name suggested: Free and Open Source, it means we also give away our software free. Otherwise, we will have to find a second job to make living. Currently, I think a viable way to make money on Linux is doing works related to client-server. Another way to developer my career is to become expert in developing business applications for companies. This is more on business, not on specialized IT fields so I am not really interested. Another alternative is programming on mobile devices, such as iPhone, Android and it seems very promising and easier to approach. Another way is to become a computer scientist and research on academic subjects such as AI, human-computer interaction, but this is far beyond my reach, so I won't invest my time on it until I feel I am experienced enough. That's all I can think of for now. I may miss a lot of things, so I need more opinions as input to get the big picture of the industry for my career path.

    I have some problems connecting to my office from home. I'm getting the following error message: Remote Desktop Connection cannot verify the identity of the computer that you want to connect to. Try reconnecting to the Windows-based computer, or contact our administrator. I have downloaded CoRD, and for some reason, that works okay. I can also connect from a Windows 7 running on VMWare Fusion. On Windows 7, I use SonicWall Global VPN Client, and on the Mac, I use VPN tracker, if that is related... What's going on?

  • Does the term "Learning Curve" include the knowing of the gotchas?

    - by voroninp
    When you learn new technology you spend time understanding its concepts and tools. But when technology meets real life strange and not pleasant things happen. Reuqirements are often far from ideal and differ from 'classic' scenario. And soon I find myself bending the technology to my real needs. At this point I begin to know bugs of the system or that is is not so flexible as it seemed at the very begining. And this 'fighting' with technology consumes a great part of the time while developing. What is more depressing is that the bunch of such gotchas and workarounds are not concentrated at one place (book, site, etc.) And before you really confront it you cannot really ask the correct question because you do not even suspect the reason for the problem to occur (unknown-unknown). So my question consiststs of three: 1) Do you really manage (and how) to predict possible future problems? 2) How much time do you spend for finding the workaround/fix/solution before you leave it and switch to other problems. 3) What are the criteria for you to think about yourself as experienced in the tecnology. Do you take these gotchas into account?

  • Asus M4A79XTD-EVO / AMD Phenom II X4 965 Crashes / BSOD / Hangs / Restarts

    - by Tiby
    I'll try to be as concise as possible because I have a lot to say about my problem, but I'd rather say it when asked or when I feel it's necessary, just to make this initial reading clearer. For about a year and a half I have periods when my system has all the problems in the title (I'll use the word 'crash' for either one). I'll list some patterns and what I tried to do and what were the results, but the list is not exclusive: usually it crashes when a CPU-intensive operation is in progress, like a game or video encoding or HD movie rendering, but also sometimes crashes when I'm doing nothing after a first crash the system is very unstable and sometimes it crashes even during POST, or doesn't boot at all Some months ago I went to a local service (one that you just put your computer on the table and sit there with a guy and trying to figure out the problem, very rare these days) and they used OCCT and it crashed every time he changed some part to test it out (PSU, RAM, video card, HDD). The last one was the CPU. They changed the CPU and it didn't crash any more. Then when they put my CPU back, it also didn't crash. We figured that the trouble was the thermal paste (probably some 2 years old) because it was the only thing changed while testing. Up until 2 weeks ago, I haven't had any more problems. 2 weeks ago the problems reappeared. I changed again the thermal paste, put some Arctic Silver 5, and for about a week everything worked perfect (tried some games, video encoding, no more crashes). But again it started crashing in the same fashion as the first time. But now, instead, I figured out a very odd behaviour: when I start some of the apps above, in most cases it crashes if I start OCCT and turn on the CPU test, and run any of the programs above, it doesn't crash, even if the CPU is on 100% load (and 65-70 degrees Celsius temperature) if I shut down OCCT and continue using the programs, it crashes in a very short period of time (even if the CPU is on 5-10% load and 40 degrees) There are so many patterns and temporary solutions that I figured out in this year and a half period of time, that I can't include them all because I don't know which one are more relevant, but I'll happily provide any details you ask. My system is: CPU: AMD Phenom II X4 965 (3400 MHz - 125W) MB: ASUS M4A79XTD - EVO RAM: Corsair Vengeance 8 GB (2 x 4GB) CL8 1600MHz Video: HIS Radeon HD5770 1GB PSU: Corsair 750W HDD: Western Digital 1TB OS: Win 7 Enterprise 64 BIT (also tried with Windows Server 2008 R2 Trial and Win XP)

  • How to get rid of NAT in a LAN?

    - by Alberto
    Currently the LAN I manage is organized as follows: internal network (192.168.1.0) which uses a Linux server as a gateway (internal address on interface br0 192.168.1.1, external address on interface br1 10.0.0.2) through NAT; then the 10.0.0.0 network has another gateway (10.0.0.1) which through another NAT connects the whole thing to the internet. What I would like to achieve is to configure the Linux server so that the first layer of NAT is no more necessary, so that for example a computer in the 10.0.0.0 network can ping every computer in the 192.168.1.0 network. I deleted this iptables rule: iptables -t nat -A POSTROUTING -o br1 -j SNAT --to-source 10.0.0.2, but of course now computers on 192.168.1.0 cannot reach the internet; ip forwarding is of course enabled. What's missing here? Thanks

  • Why can't I install from software center?

    - by user64720
    There was a problem upgrading to Firefox 13. This error kept returning: /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb W: Waited for dpkg --assert-multi-arch but was not there - dpkgGo (10: There are no "child" processes). Now it seems that there is some problem with dpkg and I can't install anything from software center. I already tried to clean previous packages with sudo rm /var/lib/apt/lists/* -vf and then sudo apt-get update, it didn't work. When running sudo dpkg --configure -a, I get this: dpkg: problems with dependencies prevent the configuration of firefox-globalmenu: firefox-globalmenu depends on firefox (= 13.0+build1-0ubuntu0.12.04.1); however: The package is not installed. dpkg: error while processing firefox-globalmenu (--configure): problems com dependencies - leaving unconfigured There has been found errors while processing: firefox-globalmenu What should I do to fix this?? EDIT: I don't have the necessary expertise to understand why what I did worked and what was causing the conflict, but anyway, since there was a problem with firefox-globalmenu:, I went to synaptics package manager, I removed this particular package and reinstalled it. After that, I was able to install Firefox from synaptics and also any other applications from software center. However, still there was a problem, when running sudo apt-get update, the following kept returning: Failed to get gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages Verification code hash doesn't match. E: Some archives index failed at being downloaded. They have been ignored, or older copies are used instead. So I typed sudo rm /var/lib/apt/lists/* -vf in terminal and then again sudo apt-get update and everything is fine now. I did this before an answer was posted, anyway I agree the problem was that particular package and its removal. So I'll mark the below answer as accepted.

  • How can I set my resolution to 1280x1024 on an Acer Aspire Revo 3700?

    - by torbengb
    I've just set up a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. Almost everything works OK, but the graphics are not OK: the recommended Nvidia driver is activated but the monitor is not detected, so the resolution is wrong. How can I make Ubuntu detect my monitor? How can I get the proper resolution (1280x1024) in Ubuntu? I know that my monitor is not a CRT but an LCD: it's a BenQ, model T905, with 1280x1024 resolution at 60Hz, connected via a normal VGA cable. DVI or HDMI is not an option.
