• Is it possible to install ffmpeg and x264 on a Synology Diskstation 209?

  - by Kieran Benton

  Hi, Complete linux novice here! :) I'm trying to get my brilliant DS209 NAS box to do some transcoding for me of a few AVI videos to a format suitable for my Apply iTouch - yes I could do it with another machine and Handbrake but it would be really useful to offload some of this to the NAS to do overnight. I've managed to install ipkg onto my DS209 NAS box and have played around with installing some packages (binutils, mono, bash etc). I've even managed to install ffmpeg from ipkg and put together the correct command line profile to do the encoding as a .sh file: time ffmpeg -y -i $1 -f mp4 -title $2 -vcodec libx264 -level 21 -s 426×320 -b 512k -bt 512k -bufsize 4M -maxrate 4M -g 250 -coder 0 -threads 0 -acodec libfaac -ac 2 -ab 64k $3 However running this I get a missing dependency on libx264. I've tried building this from the latest source in git, but I get errors during the make process that I just don't understand (way out of my depth). encoder/set.c: In function 'x264_sei_version_write': encoder/set.c:491: error: 'X264_VERSION' undeclared (first use in this function) encoder/set.c:491: error: (Each undeclared identifier is reported only once encoder/set.c:491: error: for each function it appears in.) make: *** [encoder/set.o] Error 1 Can anyone else try building it or give me a pointer as to what I can do to get this going? Its been a good learning experience so far! Thanks.

• Displaying google analytics data on my website

  - by anon-user0

  I sale adspace for my websites directly to the advertisers. I ad page where I want to show google anaylytics information that update automatically without me having to manually update everyday or every month. Something like this: http://wstats.net/en/website/riverplate.com#stat_trafic I don't want to use embedded or iframed third party services. I know google has public API and you can connect it to google graph API to to show pretty graphs. There is a tutorial by google here on how to do it: https://developers.google.com/analytics/resources/articles/gdataAnalyticsCharts Few problems: I don't know much javascript The javascript seems to prompt for authntication as opposed to login automatically. (from my understanding by reading comments on the code) Does anyone know of any ready made script that does what I am looking for or know how I can fix this code that will allow me to display analytic info without authenticating? Thanks.

• Copying email with qmail and Plesk

  - by Greg

  I need to keep a copy of all outgoing and incoming email (for a single domain if possible) using qmail or Plesk. I can't recompile qmail, so qmailtap is out of the question, as is setting QUEUE_EXTRA in extra.h. I'm pretty sure it should be possible with Plesk's mailmng utility, aka Mail Handlers but I'm having trouble getting them to work. I've registered 2 hooks: incoming hook ./mailmng --add-handler --handler-name=incoming --recipient-domain=example.com --executable=/xxx/incoming.sh --context=/xxx/incoming/ --hook=before-local incoming.sh #!/bin/bash # The email is passed on stdin - grab it to a variable e=`cat -` # $1 = context (/xxx/incoming) # $3 = recipient ([email protected]) # Create /xxx/incoming/[email protected] mkdir -p $1$3 # Save the email to /xxx/incoming/[email protected]/0123456789.txt echo "$e" > $1$3/`date +%s%N`.txt # Echo PASS to stderr echo 'PASS' >&2 # Echo the email to stdout echo "$e" outgoing hook # ./mailmng --add-handler --handler-name=outgoing --sender-domain=holidaysplease.com --executable=/xxx/outgoing.sh --context=/xxx/outgoing/ --hook=before-remote The outgoing.sh file is the same as incoming.sh, except replace $3 (recipient) with $2 (sender). The incoming hook does work, but saves 2 copies of each email - one before and one after SpamAssassin has run. The outgoing hook doesn't seem to get called at all. So finally, my questions are: How can I make the incoming hook save only a single copy (preferably after SpamAssassin has run)? How can I get the outgoing hook to work?

• QMake et au-delà : le futur de l'outil de compilation de Qt, un article de Marius traduit par Louis

  Bonjour, QMake est un outil qui simplifie grandement le processus de compilation pour de différentes plateformes. Son prédécesseur était un script Perl nommé TMake, qui, dépassé, avait vite été remplacé par le QMake que nous connaissons. Aujourd'hui, ce dernier semble à son tour ne plus apporter une réponse au besoin initial, étant devenu difficile à maintenir. Ainsi, devant la diversité et le nombre des avis internes, Marius a décidé de rédiger un article dans les Qt Labs Blogs afin de demander aux développeurs aguerris leur avis sur la question. Qu'allons-nous faire de QMake ? C'est la question, posée par Marius en début...

• Simultaneous Animation for a GameObject - Unity3D

  - by Fahim Ali Zain

  Its my second week with Unity. I am doing a 2D game and I have a small GameObject which should change its sprite along with following a definite path defined in Animation Curves. I did both of them in separate .anim files since the transform animation had many keyframes, i thought it wont be good to put the '2' sprite keyframe repeatedly along side the transform keyframe. But the problem is, I cant get it both working together at the same time. I dont want any blending because the animation is timed well already. Also, I tried deleting the sprite change animation and tried it under script changing the SpriteRenderer.Sprite property under Update(); but it works only when the Animator component is disabled in the GameObject. Any Solutions ? :)

• Ubuntu One Windows Client 3.0.1 - Sync not connecting

  - by Tweezak

  I've got sync working at home on Natty and I need to access files at work. I've just installed client 3.0.1 at work on Windows 7. It's finding my account and sees what devices are already set up for sync but it just repeatedly tries to sync (File sync starting...) and after a while fails (File Sync is disconnected.). This cycle loops endlessly. I'm suspicious that it's a problem with my proxy setup. My employer doesn't use a manual proxy configuration but instead uses an automatic configuration script at a specific http address. Does U1 recognize that kind of setup or is it only looking for a proxy server in the form of an address/port?

• Why doesn't apache2 respect my envvars file?

  - by Avery Chan

  My envvar files has these lines in it: export APACHE_RUN_USER=www-data export APACHE_RUN_GROUP=www-data My apache2.conf has these lines in it: # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} But when I run apache2 -M I get this: apache2: bad user name ${APACHE_RUN_USER} A temporary fix is to hard-code www-data into it my apache2.conf file. There was some speculation here that this was because some configuration script didn't replace the env vars correctly in my apache2.conf file. Regardless how do I get apache2 to consult my envvars file? As another data point this site seems to indicate the envvars is generated at build, but read by apache2ctl at runtime, suggesting that this file isn't just poop leftover by the build process.

• Scripting for a C#, multiplayer game

  - by Vaughan Hilts

  I have a multiplayer game written in C# and we've recently been creating a lot of content but have been looking for a way to give our entities customization logic that the designers can hook into. I took a look at this post. With something like this in mind (using C# as a scripting language); I have a few questions. 1) Would one embed the script itself in the entity object before persisting to it to the disk? Is this okay? 2) Would I compile once per scripting then - this seems like a lot of overhead to store all these compiled Assemblies to execute. Any general advice on how to do thigns is welcome, too. These entities are generated on the fly inside the editor and could be composed of a lot of different things.

• Linux: prevent VNC from swapping like mad

  - by Weezy

  I'm accessing a MacMini (with MacOS X 10.4) from my Linux machine using VNC and there's an issue that is driving me crazy... My Linux machine has 4 GB of ram and I run a lot of various apps on it and I've got no issue at all. It's all snappy and don't hear the hard disk swapping/read/writing too often. Now with VNC, the hard disk is swapping like mad... When I'm moving things on the OS X desktop. So I was thinking of creating a ramdisk and forcing the temp VNC files to go into that ramdisk but the problem is I can't find any temp files. I've attempted to do that: #!/bin/bash while [ true ] do lsof | grep vnc done And eyeball parse the output to try to find some temp file: no luck. The VNC version I'm using is this one: $ vncviewer -version VNC Viewer Free Edition 4.1.1 for X - built Jan 30 2009 19:33:16 Copyright (C) 2002-2005 RealVNC Ltd. No matter how much data is coming from the Mac, there should be plenty of memory (4 GB of ram) so there's really no reason to swap like crazy. This is driving me mad. Any help as to how I could solve this problem is most welcome because this is literally driving me nuts.

• How to make sudo remember my password and how to add an application to startup

  - by Bragboy

  I guess this should be a simple thing for ubuntu users out there. I have two questions. Whenever I need to run some command that requires permission from root, I run as sudo followed by that command. It would be nice if that does not prompt for password (but I should still be issuing a sudo to make sure that I know what I am doing). How to do this? Every time I start my system, I go to terminal and start my VPN using sudo vpnc. This is almost everytime! How to automate this to a startup script? Help much appreciated! Thanks

• Dual Partion windows not working ?

  - by Jason Wagner

  I originally set up Ubuntu "along side" widows(Vista) and realized it was done though wubi after I tried to set up a VB and didn't have enough room. I then repartitioned the HD and did a stand alone Ubuntu install. The problem is when I try to boot windows it starts to load then does a flash and heads back to the start up boot page with ubuntu and windows on the boot screen. Ubuntu loads fine, everytime but windows goes back. Here is the boot script info. http://paste.ubuntu.com/6405545/ Any help would be appreciated. I want to leave windows behind but still need it for some things on this machine.

• Openldap with ppolicy

  - by nitins

  We have working installation of OpenLDAP version 2.4 which is using shadowAccount attributes. I want to enable ppolicy overlays. I have gone through the steps provided at OpenLDAP and ppolicy howto. I have made the changes to slapd.conf and imported the password policy. On restart OpenLDAP is working fine and I can see the password policy when I do a ldapsearch. The user object looks like given below. # extended LDIF # # LDAPv3 # base <dc=xxxxx,dc=in> with scope subtree # filter: uid=testuser # requesting: ALL # # testuser, People, xxxxxx.in dn: uid=testuser,ou=People,dc=xxxxx,dc=in uid: testuser cn: testuser objectClass: account objectClass: posixAccount objectClass: top objectClass: shadowAccount shadowMax: 90 shadowWarning: 7 loginShell: /bin/bash uidNumber: 569 gidNumber: 1005 homeDirectory: /data/testuser userPassword:: xxxxxxxxxxxxx shadowLastChange: 15079 The password policy is given below. # default, policies, xxxxxx.in dn: cn=default,ou=policies,dc=xxxxxx,dc=in objectClass: top objectClass: device objectClass: pwdPolicy cn: default pwdAttribute: userPassword pwdMaxAge: 7776002 pwdExpireWarning: 432000 pwdInHistory: 0 pwdCheckQuality: 1 pwdMinLength: 8 pwdMaxFailure: 5 pwdLockout: TRUE pwdLockoutDuration: 900 pwdGraceAuthNLimit: 0 pwdFailureCountInterval: 0 pwdMustChange: TRUE pwdAllowUserChange: TRUE pwdSafeModify: FALSE I do not what should be done after this.

• Installation automation

  - by Denis Gorbachev

  Use case: When I install Ubuntu on another computer, I need to: install all the packages that I use; make some config changes; svn checkout some projects; git clone some projects; setup .ssh/config; download a custom Eclipse build; download some additional Eclipse plugins; make many other tweaks. So, I want to run a script, like sudo install-everything-needed, that would execute these predefined actions. Is there any package that provides the backbone for such system?

• Simultanious process mysteriously ending

  - by Matt

  I'm trying to run a large air quality model, written in FORTRAN, setup with bash scripts, and run in a work queue (slurm.) The first part of the modeling is to run an "entry" model, this runs with MPI in the work queue but only on one process. At one point in the logs, there's a mysterious FORTRAN STOP, and then later the model fails because something wasn't set up properly. This FORTRAN STOP isn't from the main process, which continues running. This is a huge model, but as far as I know there should not be any other processes running at the same time. It consistently fails at the exact same spot. (I can move it by adding debug, but the debug is in the main process) How can I determine what this process is? I've tried added a call to strace -feprocess $SHELL in the run script, but I'm new to this, so if it has offered any info, I haven't been able to use it yet. The is no trace output around the FORTRAN STOP. The whole process occurs so fast that I can't seem to observe it by using ps. Is there a way I can somehow monitor all the processes being initiated from the time the work queue starts? Or some other way I can figure out what is failing? This is running on CentOS 6.4, with Slurm, compiled with PGI 13.

• How to keep "dot files" under version control?

  - by andrewsomething

  Etckeeper is a great tool for keeping track of changes to your configuration files in /etc A few key things about it really stand out. It can be used with a wide variety of VCSs: git, mercurial, darcs, or bzr. It also does auto commits daily and whenever you install, remove or upgrade package. It also keeps track of file permissions and user/group ownership metadata. I would also like to keep my "dot files" in my home directory under version control as well, preferably bazaar. Does anyone know if a tool like etckeeper exists for this purpose? Worst case, I imagine that a simple cron job running bzr add && bzr ci once or twice a day along with adding ~/Documents, ~/Music, ect to the .bzrignore Anyone already doing something similar with a script? While I'd prefer bazaar, other options might be interesting.

• lock screen before hibernating [12.04]

  - by Emanuel Ey

  So when i hibernate my laptop the screen doesn't lock automatically. To solve this if changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

• How to opendns with dynamic ip

  - by Joshua Robison

  OpenDNS is almost completely useless with a dynamic ip and most people have dynamic ip addresses. There isn't even a decent client for Linux to update your IP. There is a script you can install but it only seems to update on startup and all my child needs to do is unplug and replug the cable from the wall or router and a new ip is created totally killing the opendns service . I'm not even sure the Mac or windows ip update clients can protect from such a simple maneuver . How can I get my ip address to constantly update with opendns, is my question.
