  • /etc/environment and cron

    - by clorz
    Hi, I've got two machines: Fedora and CentOS. And a cronjob 0-59 * * * * env > /home/me/env.log On CentOS I can see that /etc/environment is affecting the output while on Fedora it does not. I want Fedora to be like CentOS. What do I need to make it happen? /etc/pam.d/crond on Fedora auth sufficient pam_rootok.so auth required pam_env.so auth include system-auth account required pam_access.so account include system-auth session required pam_loginuid.so session include system-auth /etc/pam.d/crond on CentOS auth sufficient pam_env.so auth required pam_rootok.so auth include system-auth account required pam_access.so account include system-auth session required pam_loginuid.so session include system-auth /etc/security/pam_env.conf is the same on both systems and consists of commented out lines. Even if I make /etc/pam.d/cron.d files the same, problem still persists.

  • Accessing localhost (xampp) from another computer over LAN network - how to?

    - by vr3690
    I have just set up a wi-fi network at home. I have all my files on my desktop computer (192.168.1.56) and want to access localhost over there from another computer (192.168.1.2). On my desktop I can access localhost through the normal http://localhost. Apache is running on port 80 as usual. Exactly what do I have to do to achieve this? There is documentation on the net but they either don't work or are too fragment and confusing to understand. I think I have to make changes to my apache's httpd.conf file and the hosts file. Any ideas as to what changes to make?

  • Network printer problem with 12.04

    - by G. He
    I had an HP LaserJet 3030 printer connected to an Ubuntu box. It worked fine with 11.10. I was able to print from Ubuntu as well as from Windows and Mac from the home network. About a month or so ago, I upgraded 11.10 to 12.04, then things started to falling apart. My Windows 7 laptop couldn't print to the printer any more. Today, I installed many updates on 12.04, hoping that would fix the printing problem. Unfortunately, it made the situation much worse. Now not only my Windows 7 laptop won't print, my XP desktop won't print either. Every time I print something from the Windows computer, the Ubuntu box logs an error message in /var/log/samba/log.'machineName' as: _spoolss_OpenPrinterEx: Cannot open a printer handle for printer \\server. It is interesting that it uses the server name as the printer, not the \\server\xyzprinter as the printer name. Anyone had a similar problem? Anyway to work around the problem?

  • Boot process enter an infinite loop after installing Ubuntu 11.04 together with Windos 7 and XP

    - by Andreafc
    I have a new computer ACER Aspire X3960 which came with Widows 7 preinstalled. I made a new partition where I installed Windows XP and then I installed in new logical partitions (a Swap, a / and a /home partition) Ubuntu 11.04. At the end of the process, the computer enters the very first screen where it says "press DEL to enter BIOS setup, press F12 to enter BOOT options". After a few seconds, the screen goes blank, the computer beeps and then it presents the same screen again. It doesn't even ever go to the grub options of which operating system I want to start. It just loops there forever. I tried to fix the (eventually damaged) grub following these instructions (unfortunately in german) http://wiki.ubuntuusers.de/GRUB_2/Reparatur from a LiveUSB, which I'm also using to post this question. Now I found here that someone asked for the results of the Boot Info Script. Here are mine (I hope I did right in trying to upload the file): http://paste.ubuntu.com/736032/ Can anybody help? Thank you very much. Andreafc

  • Weird files in User folder

    - by Vervious
    In my user folder (C:/Users/myAccount/) theres a set of interesting hidden files that I've never seen before (right now it's a fresh install of Windows 7 Ultimate). These are: NTUSER.DAT, ntuser.dat.LOG1, ntuser.dat.LOG2, and NTUSER.DAT(whole chain of numbers and letters).TM.bif, NTUSER.DAT(whole chain of numbers and letters).TMContaineretcetc.regtrans-ms, and another similar one. When I try to delete them, it says the system is using them. I've never seen these files before. Are they ok to delete? Or should I leave them in my home folder? I always keep "Show hidden files" as well as "Show System files" checked, since I prefer being able to see all the files on my computer. If I shouldn't delete them, is there at least a way to tidy them up a bit? Thanks.

  • How do I fix my ethernet card losing network connection every few minutes with kernels 3.8.x?

    - by igoryonya
    I'm using Ubuntu 13.04. My laptop is Acer Aspire one 722-c58rr, and my ethernet card works for a few seconds at a time with kernels 3.8.x, however, kernels 3.5.x and below worked fine. On kernels 3.8.x, it works fine after boot for about a minute, then it looses network connection. When pinging to some address, it says: network address is unreachable, but it can ping it's own address. The address is statically configured. Everything was working fine before. I went to vacation, where I used WiFi and 3G connections, so I didn't notice that the problem occurred. Came back home, plugged in into the ethernet. It worked for a minute then stopped. Rebooting commutator fixed the problem. Tried to connect to a different commutator, same problem. Unplugging and plugging the cable fixes the problem for another minute. Disconnecting eth in Network manager and reconnecting it again, does the same thing. WiFi has no such problem. Tried to use a different cable that works fine on another computer, the same problem. Tried to boot with the lower kernel version, the same problem was happening until I got to the version 3.5 of the kernel series. Everything works fine on the kernel 3.5.x, but I don't want to miss out on the new kernel's features. Executing commands, when booted with 3.8 kernel series, give the following results: lspci| grep -i eth: 06:00.0 Ethernet controller: Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1) dmesg| grep eth1: [ 89.548291] atl1c 0000:06:00.0: atl1c: eth1 NIC Link is Up How do I fix it, while staying in the new kernel version?

  • load syntax as per file prefix

    - by Richo
    Firstly, I hope that this is the right place. I couldn't decide between here and superuser. My home directory lives in an svn repo. all my dotfiles are in version control so that I can track them across multiple machines, and they all source an unversioned .local (ie, .screenrc.local, .vimrc.local etc) which can override/make local changes to the environment in a machine specific way. The problem is that vim understands how I want to edit many of these config files, but loses it's mind when I open a .local, and honestly, I'm not really sure what it does to work out how to syntax highlight etc a file like .screenrc the pseudocode for what I'm after is: if OpenedFile.ends_with(".local") behave_as_per OpenedFile[0:-6] endif I hope this makes sense and hopefully someone can shed light on whether or not this is possible.

  • Cannot delete movie on iTunes for iPhone 4?

    - by Jian Lin
    I was on vacation and took some videos, and now the iPhone 4 memory is near full. So I tried to delete other experimental movies I made using Handbrake, so that I can take more video or photos, but if I plug the iPhone 4 into my Notebook computer, I can seem to delete it on iTunes? Maybe because the computer I sync with the iPhone 4 is at home (a desktop), but not with me on vacation. I can't delete it on iTunes, can't delete it on iPhone itself. I am stuck during the vacation, or is there a way to handle it?

  • Should a software developer get a yearly equipment budget?

    - by CrazyDart
    I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

  • How to fix rogue Firefox window?

    - by Colonel Panic
    I have a rogue Firefox Window which has no tab bar, and no orange Firefox menu button. It has no back button either, nor no home or bookmarks buttons. My other Firefox windows are fine. How can I right the bad window? Sometimes in Google Chrome I encounter similar rogue windows. I tame them by right-clicking and choosing 'show as tab'. Edit: I want to keep the window open, I just want to reintegrate it into society.

  • IIS7.5 is only resolving to the Default Web Site

    - by Dennis Burnham
    I am able to access only the Default Web Site on a Windows 2008 R2 Server which is running IIS 7.5 The Default Web Site's binding is to "All Unassigned", same way as I have done it on a different machine running IIS6 under Windows 2003 Server. The bindings of the desired Web Site have the IP address of the server and the correct home directory. Regardless what I do, the only page content I can see is the default index page in the wwwroot directory which is the Default Web Site. What must I do to deliver the correct content from the Web Sites that are configured in IIS7.5?

  • how to fully unit test functions and their internal validation

    - by Patrick
    I am just now getting into formal unit testing and have come across an issue in testing separate internal parts of functions. I have created a base class of data manipulation (i.e.- moving files, chmodding file, etc) and in moveFile() I have multiple levels of validation to pinpoint when a moveFile() fails (i.e.- source file not readable, destination not writeable). I can't seem to figure out how to force a couple particular validations to fail while not tripping the previous validations. Example: I want the copying of a file to fail, but by the time I've gotten to the actual copying, I've checked for everything that can go wrong before copying. Code Snippit: (Bad code on the fifth line...) // if the change permissions is set, change the file permissions if($chmod !== null) { $mod_result = chmod($destination_directory.DIRECTORY_SEPARATOR.$new_filename, $chmod); if($mod_result === false || $source_directory.DIRECTORY_SEPARATOR.$source_filename == '/home/k...../file_chmod_failed.qif') { DataMan::logRawMessage('File permissions update failed on moveFile [ERR0009] - ['.$destination_directory.DIRECTORY_SEPARATOR.$new_filename.' - '.$chmod.']', sfLogger::ALERT); return array('success' => false, 'type' => 'Internal Server Error [ERR0009]'); } } So how do I simulate the copy failing. My stop-gap measure was to perform a validation on the filename being copied and if it's absolute path matched my testing file, force the failure. I know this is very bad to put testing code into the actual code that will be used to run on the production server but I'm not sure how else to do it. Note: I am on PHP 5.2, symfony, using lime_test(). EDIT I am testing the chmodding and ensuring that the array('success' = false, 'type' = ..) is returned

  • Turn a Kindle into a Weather Display Station

    - by Jason Fitzpatrick
    The e-ink display, network connectivity, and low-power consumption of Kindle ebook readers make them a perfect candidate for an infrequently refreshed high-visibility display–like a weather display. Read on to see how to hack a Kindle to serve up the local weather. Tinker and hardware hacker Matt Petroff hacked his Kindle to accept input from a web server and then, graciously and in the spirit of geeky projects everywhere, shared his source code. He explains the heart of the project: The server side of the system uses shell and Python scripts to convert weather forecast data into an image for the Kindle. The scripts first download and parse forecast data from NOAA via the National Digital Forecast Database XML/SOAP Service. After parsing the data, the data then needs to be converted into an image. This is accomplished by preprocessing a specially crafted SVG file to insert temperatures, forecast symbols, and days of the week. This SVG is then rendered as a PNG using rsvg-convert and converted to a grayscale, no transparency color space as required by the Kindle using pngcrush. Finally, it is copied to a public location on the web server. The Kindle is set to refresh twice a day (you could easily tweak the scripts for a more frequent refresh) and displays the forecast as seen in the photo above–with crisp and easy to read text and icons. Hit up the link below for more information and the project’s source code.

  • What's a good web-based application for storing your book collection?

    - by JJarava
    Hi all! I'm looking for a (better if web-based; i.e., something I can install in my home server on my LAN) software to keep track of my books/DVDs/etc. I already know of Readerware offerings, which I find quite interesting, but I'd like something that is Web-based, so I can run it on my MacMini on the living room, and access it from any of the comuputers in the house. I've been googling around, and I've been quite surprised to NOT find any clear option. Alternatively, good "native" software for Windows/MacOSX will be more than welcome. Thanks a lot PS: Given the # of interesting suggestions for Web 2.0, ASP-Hosted type sites, I've clarified the question a bit: I'd prefer some software that I can install and use in my systems, not something "in the cloud" (although I'll check the suggestions out!)

  • Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

    - by Joe
    After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

  • Using Zentyal to control several servers

    - by user1301428
    I am currently in the process of creating a home server, made up of several virtual machines, each running a different type of server (i.e. a file server, a multimedia server, a firewall and a print server as of now). Today I discovered this new software, Zentyal, which looks interesting for system and network administration. However, I haven't understood one thing: can it be used only with its preconfigured packages or can it also be used to control other servers running other programs (in my case, the four virtual machines)?. Also, would you suggest to use such a program or do you think it's better to control each server on its own?

  • Hostname confusion (Ubuntu Server 10.04)

    - by letseatfood
    I have just setup Ubuntu 10.04 Server Edition. I have been following this tutorial. The DNS information seems to be setup correctly now, but I am confused about the hostname. Currently it is laughingbuddha.home. That is a name I created. Now, I am mainly not sure how to connect from another computer on my network. I basically want to be able to put PHP files on the server box and then test them via a web browser on my other computer. So, I think I digressed from my first question, but would somebody please help me figure out if the hostname is okay for doing what I need to do? Thank-you!

  • Critical (Unixlike) Distros for Sysadmin Hopefuls to Have Experience With

    - by Interwebs
    Hi All, I'm trying to learn to be a Unix/Linux Sysadmin, and am hoping to get some hands-on experience by setting up a few installs (VMs, old comps, and the like) at home and practicing administering them. I was wondering, in the experience of those on this site, which distros are critical to be comfortable with. Obviously, to a certain extent, they're all similar, but there are substantial enough differences between administering, say, Debian, OpenSolaris, FreeBSD, and CentOS. So, which distros are most important to practice with in your opinion? Which have had most demand/come up most often in actual work situations? Thanks!

  • What happens when router has been set to incorrect time?

    - by iamrohitbanga
    I have a D-Link router for my home Wi-Fi network. Everyday at least once the internet suddenly goes down. I am simply not able to connect to the Wi-Fi network. If I just restart the router, it starts working. To debug the issue I logged into the admin panel and noticed the time was set to something in 2002. I have set it to the correct time. Will wait to see if that fixes the problem. In the meanwhile I want to know what can go bad when the router has been set to show an incorrect time? What are the kinds of problems expected? My Wi-Fi was working just fine most of the time, but sometimes it lost the connection. Could this be linked to the incorrect time setting?

  • MacBook repeatedly disconnects from WiFi

    - by redwall_hp
    I have an early 2008-model MacBook (2.4GHz). The WiFi router I have at home is a Linksys WRT54GX2 that I have had for a few years. My MacBook has recently started disconnecting from the router every few minutes, which is rather annoying. I can reconnect again without having to restart the router or anything, as it seems that the MacBook is just dropping the connection. I have tried changing the channel on the router, and upgrading the laptop from Leopard to Snow Leopard made no difference either. I'm only about six feet from the linksys device, so distance isn't an issue. This only happens with the Linksys router, while I can use the local library's open network without issue. The problem also seemingly becomes more pronounced after midnight. Any ideas as to what the problem could be?

  • Quitting a small start-up where you are a primary developer?

    - by programmx10
    Just curious to hear from other people who may have been in similar situations. I work for a small startup (very small) where I am the main developer for a major part of the app they are building, the other dev they have does a different area of work than I do so couldn't take over my part. I've been with the company 5 months, or so, but I am looking at going to a more stable company soon because its just getting to be too much stress, overtime, pressure, etc for too little benefit and I miss working with other developers who can help out on a project. The guy is happy with my work and I think I've helped them get pretty far but I've realized I just don't like being this much "on the edge" as its hard to tell what the direction of the company is going to be since its so new. Also, even though I'm the main dev for the project, I would still only consider myself a mid-level dev and am selling myself as such for the new job search. Just to add more detail, I'm not a partner or anything in the company and this was never discussed, so I just work on a W2 (with no benefits of course). I work at home so that makes it easier to leave, I guess, but I don't want to just screw the guy over but also don't want to be tied in for too long. Obviously I would plan to give 2 weeks notice at least, but should I give more? How should I bring up the subject because I know its going to be a touchy thing to bring up. Any advice is appreciated UPDATE: Thanks everyone for posting on this, I have now just completed the process of accepting an offer with a larger company and quitting the startup. I have given 2 weeks notice and have offered to make myself available after that if needed, basically its a really small company at this point so it would only be 1 dev that I would have to deal with... anyways, it looks like it may work out well as far as me maintaining a good relationship with the founder for future work together, I made it out to be more of a personal / lifestyle issue than about their flaws / shortcomings which definitely seems to help in leaving on a good note

  • Slightly off topic - How to Fix Sky Go Error [t6013-c1501] (and [t6000-c1501])

    - by bconlon
    Sky doesn't seem to understand what their own errors mean, so I cobbled together an understanding from some other posts and managed to get it working.When you see the error [t6013-c1501] instead of your TV programme in Sky Go, it seems to mean:'You registered a device, but then changed the hardware, so now I'm confused!'In other words, the Digital rights management (DRM) used between Sky Go and Silverlight stored an old fingerprint of your PC, but rather than recognising this and allowing you to remove the device, it just disappears from the 'Manage Devices' page.DISCLAIMER: Perform the following steps at your own risk. It worked for me, but I didn't care if it broke stuff. If you care....don't do it!So, to fix this I did the following:1. Login to Sky Go and click 'Watch live TV' from the home page. It will attempt to show Sky News and fail with the error [t6013-c1501].2. Right click on the error and you should see the Menu option 'Silverlight'. Select this and a dialog should appear. Click the 'Application Storage' tab and delete any entry that relates to sky go. Clcik OK to close the dialog.3. Open explorer and navigate to the folder C:\ProgramData\Microsoft\PlayReady4. Rename the file mspr.hds to mspr.hds.OLD5. Go back to the browser and click F5. You may need to logout/login (not sure).Note: Don't rename/delete the folder C:\ProgramData\Microsoft\PlayReady or you will get the error [t6000-c1501]. The folder must exist in order for the new file to be created by Silverlight. Techie talk:So whoever wrote the code to create a new mspr.hds file didn't write code to check the folder existed causing what I assume is a generic error t6000, probably something like:catch (Exception ex) { WriteToLog("Oops, something broke!"); }#
