• Monitoring outgoing bandwidth of application

  - by jnolte

  I currently have a VPS that is consuming a ton of outgoing bandwidth and I am trying to drill down to where this may be coming from. Does anyone know of a logical way to go about finding out which pages on the site are consuming the most outgoing data. We have done a ton of front-end optimizations to the site and our google page speed rankings ar 85% so I feel we have done a pretty great job at optimizing the site for speed. Can someone lend some insight on how they have made similar optimizations? Application / Server Stack LEMP Running Varnish Cache / PHP5-FPM WordPress running w3 Total Cache Ubuntu 12.04 LTS

• Error installing Arch Linux

  - by Garethj94

  So, I am trying to install Arch Linux on my Acer Aspire 4830tg, but I keep running into problems. Some background knowledge, I am trying to install Arch off a usb stick and I got the iso image using bittorrent. I am also trying to install it alongside of Windows 8 (which is already installed). So when I boot into Arch linux I get this error: :: Mounting '/dev/disk/by-label/ARCH_201212' to 'run/archiso/bootmnt' Waiting 30 seconds for device /dev/disk/by-label/ARCH_201212 ... ERROR: '/dev/disk/by-label/ARCH_201212' device did not show up after 30 seconds... Falling back to interactive prompt You can try to fix the problem manually, log out when you are finished sh: can't access tty; job control turned off I know that it will work if I run it on a virtual machine but whenever I try to install it on my laptop I keep getting this error. And since you can't register for the Arch forums without a Arch terminal to run their captcha command I can't ask this on their forums.

• Getting rid of site-specific hotkeys

  - by ZyX

  How do I disable site-specific hotkeys if (and only if) they are already mapped in Opera? For example, I use <C-b> instead of <Right> and <C-h> instead of <BS>. On Stack Overflow/Super User they produce **strong text** and ## Heading ## respectively. I do not want this happen. I can examine Super User/Stack Overflow/some_other_site's javascript and write a userjs to do the job, but this method is not universal. I'm using Opera-10.51_pre6252 in Gentoo Linux.

• HP Printer scrolls "printing" forever - but nothing happens

  - by brett80

  I got a used HP Officejet 7130 all-in-one printer. I tried printing a text document, and it shows up in the queue (and says "printing"), and the printer display says "Printing" "Press Cancel to cancel job." - and it cyles that text forever, but nothing ever happens (after a couple of initial quiet noises.) I tried to print a test page from the printer, and I get the same "printing" message. I checked the hp website, and this problem is not on their list. (They are expecting a queue problem, error message, etc.) I did initially get a message that it needs new ink cartridges, but I pressed to get past that. It's supposed to try to print anyway. I don't want to buy ink cartridges for a printer that is broken. When I press it cancels correctly.

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• XUbuntu vsftpd couldnt restart

  - by Fara

  # sudo /etc/init.d/vsftpd restart Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service vsftpd restart Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) and then start(8) utilities, e.g. stop vsftpd ; start vsftpd. The restart(8) utility is also available. vsftpd start/running, process 3237 then I tried this # service vsftpd start vsftpd start/running, process 3275 # service vsftpd stop stop: Unknown instance: # service vsftpd restart stop: Unknown instance: vsftpd start/running, process 3315 # sudo service vsftpd restart stop: Unknown instance: vsftpd start/running, process 3358 I couldn't get the vsftp resrated when ever I try the restart the above happens ! How to restart ? Please advice

• How to back up server with rsync, preserving ownership/permissions without root login

  - by olilarkin

  I am setting up a backup server on which I want to run rsync over ssh to backup content on other servers every night. I would like to set up ssh keys to make it password-less, but I want to preserve ownership of files and permissions. There are a number of users on the server to be backed up which won't all exist on the backup server. What would be the best way to do this? I guess the backup job will need to connect as root to , but I don't want to enable root ssh access on the servers. thanks for any tips, oli ps, all servers are running UBUNTU Server 12.04 LTS and are behind a university firewall.

• How can I rip a DVD but merge/join episodes

  - by Nifle

  Some background. I have the Pink Panther Collection, they have about 30 episodes on each DVD. Now I want to watch this on my $MobileDevice. So I went and converted it to m4v or avi. This of course went splendid with both Handbrake and AutoGK but the problem is that I want ONE file per DVD, both Handbrake and AutoGK creates one file per episode. So here finally is my question. Does anyone know how to persuade Handbrake or AutoGK to create one video file with all the episodes? Or can anyone recommend another (free/cheep) tool for the job? Oh and no cheating by telling me to join the files after conversion. I have never found a video joiner that did not disappoint me (usually bad audio sync).

• Chrome browser full Kiosk mode in Linux (Puppy Linux)

  - by Brandon Ellis

  Let me just say thanks in advance. I am having issues getting google-chrome browser into full KIOSK MODE with no browser bar on a linux platform Looking through the google forums I have found numerous postings on how to get Chrome to show full kiosk mode BUT tried to execute with --kiosk but doesnt seem to get the job done. I dont know if this is platform specific or not, but any useful information would help. I know F11 will display the browser in full kiosk mode, with no browser bar BUT is there a way to do this with a linux script and no need for a monkey pressing F11??

• Mapping drives on MacOSX (Leopard/Snow Leopard) permanently inside LAN

  - by Shyam

  Hi, How do I "map" shared folders on a Mac, permanently? With map, I do not mean 'connect', but permanently add it to the system so it exists after reboot. Since workstations tend to shutdown, I wonder also the symptoms and cures in case that happens. In Linux, this can be done using the fstab file, but I noticed that volumes are mounted in a different structure than Linux. I need this to backup some workstations, doing a recursive job over a single directory, that should contain the shared folders. I use Terminal to access the main system, so by preference, the solution would be nice that works within a bash shell vs GUI. I can access all folders in Finder. Thanks!

• Can Acrobat 11 be made to do OCR using multiple CPU cores?

  - by tarcman.

  OCR processing takes time. Using multiple CPU cores would speed up processing. Acrobat 10 was not a multithreaded application. How about Acrobat 11? Does 11 by default do OCR using multiple CPU cores (if available)? If not, are there any workarounds, e.g. scripting, to help make Acrobat 11 do OCR using multiple CPU cores? Either through Acrobat's built in scripting language or using external scripts that launch and direct multiple single thread instances of Acrobat to in parallell to parts of the processing job. Note: This question is not too localized (not limited to a specific moment in time) because (1) Adobe does not release new major Acrobat versions very often (Acrobat 10 was released two years ago) and (2) Adobe Acrobat is a widely used application.

• How tot track which program causes my harddrive to spin up

  - by Andreas

  I have a strange problem: Every half hour one of my hard disks gets powered on again. I recognize this by the sound of a hard disk spinning up. So far I was not able to track which program could cause this. I ran Process Monitor to see whether there is an I/O peak coinciding with the spin-up. I checked Windows event viewer if there is an appropriate event at the same time Any ideas other than the usual disabling-services/programs etc. (which would be my next investigation step)? Also, it would be helpful to have a program that shows the current power status of all my drives, if there is one. Harddisk Sentinel unfortunately cannot do the job because it powers on all drives upon start and prevents their going into sleep mode. Thanks in advance. :)

• How to stop middle button in page from trying to open whatever is in my clipboard in Firefox on Ubun

  - by therefromhere

  In Firefox on Ubuntu, if I middle-click anywhere on a page that's not a link, it seems to treat whatever text is in the clipboard as a URL and tries to load it. This is annoying, since if I either accidentally click the middle button or (more often) miss a link when trying to middle-click it, I'll either go to whatever URL is in my clipboard or get an alert saying: The URL is invalid and cannot be loaded Is there any way of either: a) Disabling this functionality so that middle-click on a non-link does nothing (maybe an about:config setting?, or b) Making the functionality more intelligent, so that it will only try and open text if it looks like a URL (this seems like a job for a plugin).

• Powershell and long-running external tools?

  - by leeand00

  I'm trying to compact a MS-Access database using JetComp.exe using a powershell script. Here is the operative lines: # 4. Run JetComp LogWrite("Begin: Running JetComp") .\JETCOMP.EXE -src: $srcDB -dest: $dstDB | Out-Null #Run this command and wait for it to finish... IfErrorExit("Error Compacting Database") LogWrite("End: Running JetComp") The JETCOMP.EXE program seems to complete long before it is actually finished and the $dstDB ends up being smaller than the compact should even make it. Initially ($srcDB) it's about 1.8 GB and by the time the command finishes it's about 300,000 kb (about 0.29 gb) that's a pretty long way off from 1.8 gb which when compacted manually ends up being about 1.6 gb. Is there some sort of timeout I don't know about in powershell scripts? P.S. I know that when running JETCOMP.EXE manually, that the system often detects it as "not responding" even though it's actually getting the job done, and waiting long enough will allow it to complete.

• Is using Capistrano for user maintenance tasks on university lab feasible?

  - by danielkza

  I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

• Is it possible to remove/hide Windows title bars?

  - by Igoru

  I'm very used to my Linux desktop, but in my new job I'm forced to use Windows. For efficiency, I'm veeery used to minimize/maximize using keyboard shortcuts and move/resize windows using alt+mouse. Thus, window titlebars and borders are useless, and I can remove them using Compiz. My question is: is this remotely possible to be done in Windows Vista? I could manage to quite reduce the borders, but the titlebars still bother me. I also found that Win+M minimizes a window, and I think that would help with the shortcuts also. As a help to understand how I'm used to live, here's a completely normal [reduced] window of my home computer:

• Permissions for Scheduled Tasks on a Domain Controller

  - by silmaril8n

  I'm trying to run a Scheduled Task on a 2008 R2 Domain Controller and all was well until I set it into the production environment. I'm running the task as a Domain User that's defined in the "Log on as a batch job" setting. For giggles I also added the account to "Allow log on locally" after the former failed. When I'm prompted for the password after setting up the task I receive the error: "An error has occurred for the task ########. Error message: The following error was reported: Logon failure: the user has not been granted the requested logon type at this computer.." I'm thinking that because this a DC that maybe it needs something else?

• Apache won't start after creating symbolic link

  - by Carlin

  I'm installing apache for the first time and trying to display some webpages on localhost. Apache's default path for serving web pages is /var/www/html/ but I don't have permissions to write there. Rather than change ownership of the entire directory, I decided to get rid of the /html/ folder in /var/www/ and created it in my home directory. Then I made a symbolic link ln -s /home/me/html/ /var/www/ hoping Apache would serve web pages from my home directory while keeping the default path and following the symbolic link to my home directory. When I go to start the apache service with service httpd start I get Job failed. See system journal and 'systemctl status' for details.

• Send an Email at a future date

  - by Ryan

  I'd like to write up an email that gets sent out in a few days. I'd prefer to use Gmail, but I could use some other client if necessary. It doesn't look like Gmail has this feature in their labs anywhere, but it could just be hiding somewhere. Any ideas? EDIT: a bit more backstory on my particular situation. My wife is out of town for three weeks, and I've decided to email her every day while she's out. Unfortunately, I myself am going camping this weekend, so I wanted to pre-record a message that gets sent while I'm out. Unfortunately, FutureMail and FutureMe both are for sending email to yourself, probably for anti-spam reasons. I guess the best solution is to use thunderbird on my laptop (so it's shielded from power outages). Seems a little excessive to keep a computer running just to send a few emails, but whatever gets the job done :).

• How can I set my wireless router to run on a time schedule?

  - by Joshua Robison

  I have a Buffalo AirStation WZR-HP-G301NH I am able to access it's settings via 192.168.11.1 I'm connecting wirelessly with toshiba i686 laptop on Linux Mint Debian with service pack 3 and i686 dual core kernel This is just my home network but I know that there must be a way for large industries to shut their networks down or lock out their network access temporarily based on a time schedule, automatically. Like mon - fri the network provides access from 8am to 10pm and then automatically shuts down. I want this to affect all the computers accessing this netowork... basically all my families computers so that the internet just automatically shuts down at bedtime. I am running Linux Mint Debian and so maybe I need to make a cron job or something but does anyone know how big industries implement this and how I can do it privately? TIA

• Redmine: reposman.rb succeeds, but does not make SVN repos available to projects

  - by Joey Adams

  I'm testing reposman.rb on the command-line (before I make it a cron job): /usr/sbin/reposman.rb --svn-dir=/var/svn \ --redmine-host=http://example.com/projects --key='redacted' \ --owner='nobody' --group='nobody' It succeeded, printing messages for projects that didn't have repos yet: repository /var/svn/project1 created repository /var/svn/project2 created And printed nothing after running the same command again, indicating it remembered the repos. However, if I look at the Repository settings in Redmine for project1 and project2, they aren't set. Although the SVN repo is created, the Redmine projects aren't configured. How do I get reposman.rb to automatically configure Redmine projects to use the repos after they're set up?

• Log of cron actions on OS X

  - by Doug Harris

  Does the cron which comes with OS X log its actions anywhere? I'm not looking for output of any particular cron job, but rather log of what cron is doing. On a couple linux machines I've checked, there's /var/log/cron which has contents like: Apr 26 11:00:01 localhost crond[27755]: (root) CMD (/root/bin/mysql-backup) Apr 26 11:01:01 localhost crond[27892]: (root) CMD (run-parts /etc/cron.hourly) Apr 26 11:07:01 localhost crond[28138]: (root) CMD (/usr/local/bin/python /home/ user1/scripts/pythonscript.py) Apr 26 11:18:18 localhost crontab[28921]: (user2) LIST (user2) Apr 26 11:18:22 localhost crontab[28929]: (user2) BEGIN EDIT (user2) Apr 26 11:18:59 localhost crontab[28929]: (user2) REPLACE (user2) This shows when jobs ran, when users viewed or edited crontabs, etc. This stuff is nowhere that I've found on my Snow Leopard machine.

• BixData or Zabbix?

  - by Arafat

  Hi all, I've been using Ganglia to monitor my single Mac OSX server which runs Apache and MySQL. I'm ok with it. Now we are upgrading our servers, 6 IBM X3650 M3 and 2 Fujitsu servers. 2 IBM for Apache cluster and 4 IBM for MySQL NDB Cluster. The other two servers are for Load balancers. All servers are going to run Debian Lenny 5 on it. Now I need to decide on which monitoring tool I should go for. I found that BixData and Zabbix does an excellent job than Ganglia, in terms of sensors and reporting. Have anyone tried the above two tools? And which tool would you suggest me? For Debian. As I'm writing this, I'm installing BixData to try.... Thanks in advance.

• Running .net application over a network

  - by Marlon

  Hello, I need some advice please. I need to enable a .Net application to run over a network share, the problem is that this will be on clients network shares and so the path will not be identical. I've had a quick look at ClickOnce and the publish options in VS2008 but it wants a specific network share location - and I'm assuming this location gets stored somewhere when it does its thing. At the moment the job is being done with a old VB6 application and so gets around all these security issues, but that application is poorly written and almost impossible to maintain so it really needs to go. Is it possible for the domain controller to be set up to allow this specific .Net application to execute? Any other options would be welcomed as I want to get this little application is very business critical. I aught to say that the client networks are schools, and thus are often quite locked down as are the client machines, so manually adding exceptions to each client machine is a big no no. Marlon
