• Set Idle Time in Ubuntu 12.04 Server

  - by ssanj

  I recently installed Ubuntu 12.04 Server and am looking for away for get the server to suspend after an idle time. When using the desktop version I could use the Gnome powersaving tool to specify the idle time. As I have no GUI on the server is there a way to set the server idle time via the commandline/config file? I will send the server a wake-on-lan packet to wake it up, if it is suspended and I need to use it.

• Git completion __git_ps1 really slow on Mac

  - by mckeed

  I've had __git_ps1 in my bash prompt for a while, but just recently (I noticed it after I did some messing around with Homebrew and rbenv), it has slowed down my prompt horribly. When I'm in a git directory I have to wait 3-4 seconds after every command for the prompt to appear. If I just mash return and watch the Activity Monitor, it shows that distnoted and Finder are using more CPU than normal during the delay. Could something git-completion.bash is doing be triggering a notification to Finder? Maybe it involves folder actions or something?

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• Import PST into Gmail

  - by John

  I'm in the process of moving my email to Gmail. I used to use Outlook and I have a massive amount of email stored in various PST files (about 7GB worth). Ultimately I'd like to store this all in Gmail so I have my entire email archive available. I imported my first PST file using Outlook's IMAP feature - dragging the folders in one by one. This worked, but was quite slow and laborious (since I had to check on it every few minutes and set the next folder going). Is there any way I can do the import - either without using Outlook, or by somehow just setting it to go and leaving it overnight without any intervention? I did look at using Google Sync for Outlook, but it looks like this will also pull down all of the email I've already uploaded, which ideally I'd like to avoid (although if this is the only option I'll do that!)

• Git push on localhost with htaccess

  - by Rooneyl

  I am looking into setting up a remote git repo. To start with I have created it on my Windows machine using xampp following this guide. All works fine except when I try to add some security, as per step 6 of the guide (for when I migrate it to my main web server). I have added passwords by using passwd and adding htaccess to the htdocs folder. This works fine (I have checked in my web browser), but when I try and push I get prompted for my password the it fails with a error (code 22). $ git push origin master Password for 'http://git@localhost': error: Cannot access URL http://git@localhost/s.git/, return code 22 fatal: git-http-push failed Any ideas?

• Can you easily turn your settings into an Operating System?

  - by PyRulez

  I know that there are ways to make your own operating system (otherwise, there would be none) but require programming skill. (I am only a hobbyist programmer, couldn't do an Operating System.) Is there any programs that can take your current operating system, with all of its settings, tweaks, and applications, and make a new ISO, or other image file, that when installed, comes with all those custom settings, tweaks, and applications?

• Giving SSH access to a user, and security issues.

  - by Kris Sauquillo

  Okay, so I have a VPS and I made an account for a friend so he can host his own domains (using the reseller features in DirectAdmin). He's asking for SSH access, and I know that this is probably a bad idea. Does he have access to my whole server, such as executing commands, accessing my domains that I host on my server? I logged into my SSH using his account details and it let me navigate around all of the root folders/files, and his account is under /home/AccountName/. Is there anyway to restrict his access to his folder only? And the commands he can use?

• Postfix - How to process incoming emails?

  - by Borivojevic

  Hello Does anybody know how to process incoming emails for virtual mailboxes in postfix? I am building web application where users add new content by sending emails to application. Email address used for each user is custom (eg. [email protected]) and it is dynamically created as a Postfix virtual mailbox. User needs to be able to send email to his custom mailbox address ([email protected]) and i want to process each incoming email, parse it's contents and populate my database with data from email. I tried using Postfix After Queue filter but what i really wont is to process emails once they are saved in users virtual mailbox folder.

• ASP.NET app on Apache Mono Ubuntu compiler error as log4net is unable to be found

  - by Jingo

  I'm trying to get a vulnerable practice ASP.NET web application (WebGoat.NET) installed on Apache Mono on Ubuntu. I've followed this guide and it all went smoothly; however, whenever I try to run the app I get this error: The type or namespace name `log4net' could not be found. Are you missing a using directive or an assembly reference? Log4net.dll is in the lib folder of the application directory. It's also in the /usr/lib/mono/gac directory. I'm not sure where else it needs to be. Any suggestions? Thanks!

• Event-Driven Debugging

  - by Brian Donahue

  Most application troubleshooting involves getting an error, analyzing the error message, and at worst, attaching a debugger to work out the real cause. What is not really covered is how to troubleshoot an applicaiton that is not errant, but is having a performance issue, and more than likely, in the middle of the night when you are snug in your bed, sawing logs. What you need is an ever-vigilant cyborg who never sleeps to sit in front of your server all night, but as SkyNet is not live yet, you can settle for the next-best thing. Windows provides performance counters and alerts that can tell you when an applicaiton reaches an unacceptable threshold of naughty behavior, but although it can tattle on your brainchild, it won't be the child psychiatrist that you need to tell you why he's pulling your server's pigtails and pulling faces at the teacher. What you need is to plug a debugger into performance monitor and have it tell you what's going on with your applicaiton at the time. For this purpose, I'd used Microsoft's MDbgEngine as the basis for an applicaiton that will dump a program's stacks, I call it Application Slicer Dicer Wonder Dumper Super Cyborg, or StackOMatic for short. StackOMatic can look at a program's behavior and tell you if the stacks are not moving, but it can also work on the command-line to dump all managed methods on the stack at will. Now that there is a command you can use to dump the stacks, all you need to do is politely tell Windows to run it when you're displeased with your creation as it's trashing the CPU of your server at 3 AM. The first step is to create a scheduled task to tell StackOMatic to dump your applicaiton. Start Task Scheduler and right-click Task Scheduler Library and then Create Task. For this exercise I'm creating a task that will dump the Red Gate SQL Monitor Base Monitor Service. In the Actions tab, I enter the path to StackOMatic and use the arguments to log the stack dump to a file: /PN:RedGate.Response.Engine.Alerting.Base.Service /OUT:c:\users\administrator\MonitorLog.txt Next, I go into Windows Server 2008's Reliability and Performance Monitor and add a new Data Collector Set. This set will produce an alert on the %Processor Time for the service. When the processor time breaches 50%, it will run the StackDumpBaseService task I created. Whenever the service misbehaves, it will append to the log file. Now when I go to work in the morning, I can see what the service was doing when it overloaded the processor and take action.

• Can you apply noatime on Ext3 partitions at realtime?

  - by bzero

  an application accesses a disk directory containing about 3 million files (including directories). I would like to apply the noatime option for that filesystem and I would like to know whether I can do that while applications are running and accessing that filesystem. the command I'd apply would look like this: mount -o remount,noatime / Any experience with that? I run one single application using the file system, and it is a 100% Java application (1 JVM running). Ubuntu Version: 9.10 (Karmic) Thanks!

• FeedDaemon and Tweetdeck not opening links in Chrome but opening in IE when IE is set default browser

  - by user2059078

  A while ago a Chrome version update failed and I ended up having a program called new_chrome.exe in the folder where chrome.exe used to be. I was very busy at that moment and I continued to work without bothering to try to fix the problem. Apparently recently another update came out and the new_chrome.exe is now gone, it was replaced by chrome.exe. Since the last upgrade happened two applications that I use a lot (not sure if others do the same) do now work anymore as they used to when I try to open links. These two apps are Tweetdek and Feedaemon. If I change the default browser to Internet Explorer they both open the links when I click on them I tried everything I could but it did not work: My Default programs look like this: and my set Default Programs looks like this: How can I fix this?

• Outlook '10 hangs often, IMAP sync

  - by user23150

  We have 3 employees using IMAP to sync with their Desktop and Android Phones. Two are using 70% of their accounts storage, another is using 80%. They all have similar counts on folder structure, etc. The employee with the 80% storage is constantly having Outlook freeze on them for up to 5 minutes at a time. I realize this is Outlook connecting and doing activity on the server, but no one else has this problem. In fact, one user with the 70% storage used uses a very slow laptop, and doesn't have freezing issues. The network is the same, the settings are the same - at a loss how to proceed? Obviously "Outlook is a crummy IMAP client" doesn't help management...

• Getting sendmail to install/work for using php mail()

  - by harryg

  I'm running WordPress on a Ubuntu VPS. When WordPress tries to send an email like a password reset or registration email it never gets delivered. WordPress uses php's mail() function. I figure it's not working as my VPS didn't have sendmail installed. So I went into SSH and installed it with sudo apt-get install sendmail which appeared to succeed. Following more googled advice I edited the php.ini file to have the sendmail path. I located it as being /usr/sbin/sendmail which I believe is typical for many *nix servers. To check I browsed to this directory on FTP. The "sendmail" directory appears to be a shortcut. Is this correct/expected? Either way the php mail function is not working. I have created a phpinfo file and a test mail php file which contains just a mail() function with my email as the recipient. Note: my VPS doesn't yet have a domain, just an IP address. Would this affect sendmail functionality? My phpinfo is here for your reference: http://95.142.166.209/phpinfo.php Do I also need postfix? I don't think I have it... Here is some of the mail log. I executed the mail function towards the end: Nov 27 18:41:02 sergeserver sm-msp-queue[5450]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:00:01 sergeserver sm-msp-queue[5497]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:01:01 sergeserver sm-msp-queue[5497]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:20:01 sergeserver sm-msp-queue[5532]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:21:01 sergeserver sm-msp-queue[5532]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:40:01 sergeserver sm-msp-queue[5568]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:41:01 sergeserver sm-msp-queue[5568]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:00:01 sergeserver sm-msp-queue[5605]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:01:01 sergeserver sm-msp-queue[5605]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:20:01 sergeserver sm-msp-queue[5641]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:21:01 sergeserver sm-msp-queue[5641]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:40:01 sergeserver sm-msp-queue[5675]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:41:01 sergeserver sm-msp-queue[5675]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:00:01 sergeserver sm-msp-queue[5712]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:01:01 sergeserver sm-msp-queue[5712]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:20:02 sergeserver sm-msp-queue[5747]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:21:02 sergeserver sm-msp-queue[5747]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:40:01 sergeserver sm-msp-queue[5782]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:41:01 sergeserver sm-msp-queue[5782]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:00:01 sergeserver sm-msp-queue[5831]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:01:01 sergeserver sm-msp-queue[5831]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:20:01 sergeserver sm-msp-queue[5866]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:21:01 sergeserver sm-msp-queue[5866]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:37:19 sergeserver sendmail[5903]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:38:19 sergeserver sendmail[5903]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:38:19 sergeserver sendmail[5903]: qARLcJYI005903: from=adminftp, size=158, class=0, nrcpts=0, msgid=<201211272138.qARLcJYI005903@sergeserver>, relay=adminftp@localhost

• ODEE Green Field (Windows) Part 2 - WebLogic

  - by AndyL-Oracle

  Welcome back to the next installment on how to install Oracle Documaker Enterprise Edition onto a green field environment! In my previous post, I went over some basic introductory information and we installed the Oracle database. Hopefully you've completed that step successfully, and we're ready to move on - so let's dive in! For this installment, we'll be installing WebLogic 10.3.6, which is a prerequisite for ODEE 12.3 and 12.2. Prior to installing the WebLogic application server, verify that you have met the software prerequisites. Review the documentation – specifically you need to make sure that you have the appropriate JDK installed. There are advisories if you are using JDK 1.7. These instructions assume you are using JDK 1.6, which is available here. The first order of business is to unzip the installation package into a directory location. This procedure should create a single file, wls1036_generic.jar. Navigate to and execute this file by double-clicking it. This should launch the installer. Depending on your User Account Control rights you may need to approve running the setup application. Once the installer application opens, click Next. Select your Middleware Home. This should be within your ORACLE_HOME. The default is probably fine. Click Next. Uncheck the Email option. Click Yes. Click Next. Click Yes Click Yes and Yes again (yes, it’s quite circular). Check that you wish to remain uninformed and click Continue. Click Custom and Next. Uncheck Evaluation Database and Coherence, then click Next. Select the appropriate JDK. This should be a 64-bit JDK if you’re running a 64-bit OS. You may need to browse to locate the appropriate JAVA_HOME location. Check the JDK and click Next. Verify the installation directory and click Next. Click Next. Allow the installation to progress… Uncheck Run Quickstart and click Done.  And that's it! It's all quite painless - so let's proceed on to set up SOA Suite, shall we?

• How can a pygame image be colored?

  - by Juicy

  I'm writing a 2d particle system for a game in Pygame[1]. For the particles, I have an image surface loaded from a file -- basically a white primitive drawn over a transparent background. I'd like the particle engine to emit variously colored particles, but I'm not sure how to tell Pygame to color the surface. I've looked through what passes for documentation, but I'm having trouble finding anything. [1] Yeah, I don't really like Pygame, but my course insists I write this project in Python.

• From where can I get "Python Launcher" for Mac OS X Lion?

  - by Phil

  I use a macbook (air) with OS X Lion on it. I have Python 2.7 installed already but I can't seem to find a "Python Launcher.app" anywhere on the system. I tried installing with with pip but it couldn't find anything to fetch. I tried searching on Google to find a downloader but my search yielded no results (for downloading). Where can I get this app? I have a folder with 20+ subfolders of GUI examples which in turn contain anywhere from 3 to 5 subfolders. I don't want to go through each within the terminal, would much rather launch these .py scrips from the finder. Thank you for your help.
