• How to replace the domain name in a Wordpress database?

  - by Cristian

  I have a Wordpress database which was installed in a development environment... thus, all references to the site itself have a fixed IP address (say 192.168.16.2). Now, I have to migrate that database to a new Wordpress installation on a hosting. The problem is that the SQL dump contains a lot of references to the IP address, and I have to replace it with: my_domain.com. I could use sed or some other command to change the that from the command line, the problem is that there are a lot of configuration data which uses JSON. So what? Well, as you know, JSON arrays uses things like: s:4: to know how many chars an element has, and thus, if I just replace the IP with the domain name, the configuration files will get corrupted. I used an app for Windows some years ago that allows to change values in a database and takes care of the JSON arrays. Unfortunately, I forgot the name of the app... so the question is: do you know any app that allows me to do what I want?

• Why doesn't Wolfram Workbench work on 64-bit Ubuntu?

  - by Ian Hincks

  I have downloaded the shell script (Workbench_2.0.0_LINUX.sh), I have run it as root with it giving no complaints, relevant looking files have appeared in /usr/local/Wolfram/WolframWorkbench/2.0/ and it has created the executable "WolframWorkbench" in /usr/local/bin. However, when I run WolframWorkbench from terminal it spits out /usr/local/bin/WolframWorkbench: 46: exec: /usr/local/Wolfram/WolframWorkbench/2.0/WolframWorkbench: not found That file does indeed exist, and is executable. I have also tried running it directly, and I have also tried running the /usr/local/Wolfram/WolframWorkbench/2.0/Executables/WolframWorkbench too. Is there something I'm missing? (I am running Ubuntu 12.04 64bit with openjdk7)

• Why does my touchpad fail on resume from standby?

  - by pst007x

  On resume touchpad disables and a reboot is needed to re-activate. Macbook Pro 6.1 Ubuntu 11.10 MAC 64bit Suspend - ok Suspend Resume - ok However, on resume in the loggin screen my touchpad works, but after I enter my password and return to the desktop the touchpad fails. A usb mouse still works fine. I have to re-boot in order to re-enable toe touchpad. This was not an issue when I had Ubuntu 10.10 32bit installed. The install was a fresh install. The bcm5974 driver will not install, says codependency errors. I manually try to install all dependencies and I get this error: E: hid-dkms: subprocess installed post-installation script returned error exit status 10 E: bcm5974-dkms: dependency problems - leaving unconfigured Thanks

• Is there a way to play the role of Javascript with any other language like C#?

  - by Gulshan

  Is there a way to play the role of Javascript with any other language like C#? One way came up in my head is, having silverlight installed, using C# instead of Javascript for all the client side scripting (Though C# is not a scripting language). Is it possible? I am not talking about something like GWT(Java) or Script#(C#). Probably the question can be stated as- "With silverlight installed, can I do everything supported by Javascript(like DOM manipulation etc) with C#?" Hope it's clearer.

• What data counters / meters are available?

  - by Santosh

  Actually I have a wireless 3G modem that works well on Windows based operating system, its interface software were made Windows centric. It can still connect to internet on Ubuntu or other linux based operating system but it won't show the data counter (the interface which shows how much data has been transferred, at what speed). If I continue to surf internet in Linux then I won't have any idea how much data has been used and it would become heavy on my pocket. So I just want a software that let me know how much data has been transferred, if there is a limiter; that warns or disconnects me when I reach predefined MBs then its better. Please let me know if there is any software or script or something like that already there.

• pfSense router on a LAN with two gateways

  - by JohnCC

  I have a LAN with an ADSL modem/router on it. We have just gained an alternative high-speed internet connection at our location, and I want to connect the LAN to it, eventually dropping the ADSL. I've chosen to use a small PFSense box to connect the LAN to the new WAN connection. Two servers on the LAN run services accessible to the outside via NAT using the single ADSL WAN IP. We have DNS records which point to this IP. I want to do the same via the new connection, using the WAN IP there. That connection permits multiple IPs, so I have configured pfSense using virtual IP's, 1:1 NAT and appropriate firewall rules. When I change the servers' default gateway settings to the pfSense box, I can access the services via the new WAN IPs without a problem. However, I can no longer access them via the old WAN IP. If I set the servers' default gateway back to the ADSL router, then the opposite is true - I can access the services via the ADSL IP, but not via the new one. In the first case, I believe this is because an incoming SYN packet arrives at the ADSL WAN IP, and is NAT'd and sent to the internal IP of the server. The server responds with a SYN/ACK which it sends via its default gateway, the pfSense box. The pfSense box sees a SYN/ACK that it saw no SYN for and drops the packet. Is there any sensible way around this? I would like the services to be accessible via both IPs for a short period at least, since once I change the DNS it will take a while before everyone picks up the new address.

• Is there a way in Windows 7 to disable "journaling"?

  - by Psycogeek

  C:\$extend\$Usn.Jrnl:$J:$data Here is a picture finally. The large strip in the center of the top band is the largest chunk, in the other, grey areas are the various clusters with it. On the right, the big long grey line is $logfile (not paging), and it is 63&nbsb;MB. Paging, 500&nbsb;MB is the dark cyan chunk, next to the yellow MFTres in the inner rings.. The disk was defragged so they could be seen easier. Not all clusters of this type of file are tagged, but the idea is there. The disk is 4k clusters, now about 12 GB size. Each cute little block in the picture is .81 MB and represents 207 clusters. The dkGreen section, is mostly the whole Winsxs pile, also interesting when they keep telling us it doesn't take much disk space. Wikipedia suggests that in previous NT systems "USN journaling" would be turned on when enabled (assumes it could also be turned off?). What aspects, services, or program is working on putting that stuff all over the disk which is known by $jrnl$ type clusters, even if it is not actual USN journaling? Is it possible in a Windows 7 system to completly disable the journaling, and what would be the ramifications of that? On a Windows XP NTFS system, I do not recall seeing the quantity of disk clusters used with these $jrnl$ names, so I do not recall this being necessary in this quantity for an NTFS file system itself? I understand that it would not be there, if it did not have a useful function :-) Information about how wonderful is fine, if that information will help track down what parts of the system create and use it. Change Journals states: Change journals are also needed to recover file system indexing Hmm, that might explain some of them, or why it was left on the disk. A crash while background indexing?

• Migrate 12.04 Wubi install to new partition with corrupted win7 install and small hard drive

  - by Robin Clark

  The move from Win7 to Ubuntu 12.04 has been honestly awesome. But I've come into a snag because my Win7 inevitably broke. I can still boot into Ubuntu even though Win7 is broken (won't boot, can't repair). I'd like to Migrate Wubi to a real partition and forget about windows. Presumably under normal conditions I would run the Ubuntu live CD, create a new partition then log back into my Wubi install and migrate using the script to the new partition. But I'm worried if I do that I'll break my current wubi set-up and be unable to migrate. I have a small hard drive, only 75GB and unfortunately my backup drive recently died so can't migrate there first and transfer over either. Does anybody have any suggestions to solve this?

• Trouble exporting Maya models to Panda3D?

  - by Aerovistae

  Having issues here. I added the Panda3D exporter script thing to Maya. 2 things: When I go to export to a .egg, no .egg is formed. Instead a fileToBeExported_temp.mb appears next to the original fileToBeExported.ma. My models use curving meshes with many subdivisions, easily in the thousands, like on the smoothed tentacles of an octopus. Will Panda be able to handle this in the first place? I can't find out on my own since it won't export.

• Video conference/chat tool that can be embedded in own website needed

  - by Olaf

  We are looking for a means (a tool, a commercial service) to enable a closed user group to start a live video conference in a browser, as part of the company website. Something like Skype, but embedded and available for everybody that has access to the page into which the tool is embedded. Most services require registration and the creation of a chat room on their website, or, as Skype or similar solutions, the installation of an extra software. What we need is a solution with some kind of a "hidden login", performed by the site's client script (which knows who the user is and forwards the credentials to the service). Any suggestion?

• I receive email not addressed to me - virus?

  - by Anne

  Every once in a while I receive email (on Gmail) that isn't addressed to me. Gmail puts it in the spam box, because it 'can't verify that it has been sent by [sender]'. The emails, when opened, contain confidential information about deliveries and paid bills (it does look an awful lot like 'real' mail from well-known companies, and it doesn't look like a scam, since the mail is informative - they give information instead of asking for credit card numbers ;-)), and I even got an email from "Facebook" that I requested a password change and that I have to 'click here' to change the password for [email address that isn't mine]. I am not the only addressee, there seems to be a whole list of Gmail addresses beginning with 'a'. The original addressee obviously has some sort of virus, and now I wonder if this could be a risk for me too. Is my email being sent around without my knowing too? I am not the kind of person who randomly clicks on shady links - I am very careful on the internet - but maybe there are other ways of catching viruses? Is there something I should do/check? Thank you for your help!

• Multi option step-by-step walkthrough? [closed]

  - by James Simpson

  I'm looking for a service ideally (but script maybe) that would allow me to create a step-by-step walkthrough, customised by options users choose in earlier steps. It is difficult to describe and if there is a better description I could Google for, please let me know! Basically, I want to start with a few options for a user to click on and then change what comes next based on that click and be able to do this through a whole walk through (explaining how to set a service up). As mentioned earlier, if it was a SAAS I could use (in the vein of desk.com) that would be perfect. Thank you and please ask questions if I've described it poorly!

• How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

  - by Samuel Rossille

  I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.

• Webshop for digital goods with voucher / gift card system [duplicate]

  - by Kelzama

  This question already has an answer here: Which Ecommerce Script Should I Use? 1 answer I'm searching for a webshop which provides the following: The shop offers digital goods (like mp3) User can buy a voucher / gift card @Reseller (Or there is a code provided in the CD) User can enter his code @ webshop and gets the download (unregistered) User can enter his code @ webshop and download is added to his/her library (registered) optional: Resellers can buy codes from the Webshop I already tried prestashop as it looks quite nice. But it needs a lot of custom programming (and has a very strange voucher-system). Customer has to add the File into the basket and add the voucher at checkout. I want to skip that ;) Is there a Webshop (Or CMS + Plugin) which provides the things I need? (it could also be a CMS with a Storage/Folder Plugin (like joomla + K2) and a possibility to activate downloads via unique Codes.) Any ideas are highly appreciated :) Thanks in advance.

• How to Use KDE Dialogs in Gtk Apps

  - by MountainX

  I want to use KDE file dialogs (file open, file save) in Firefox in Kubuntu 12.04. This requires something like the ancient KGtk script, but for KDE 4.x and recent Firefox versions. Does such a thing exist? Note, I'm not asking about theming/looks. I'm asking about actually using KDE file dialogs instead of XUL or GTK dialog. And the preference ui.allow_platform_file_picker doesn't affect this. I have already tried setting it to true and false. Neither options results in using KDE dialogs. Thanks.

• Ubuntu Server 13.04.3 doesn't boot w/ EFI

  - by user1004816

  I'm was actually trying to install Debian Wheezy (which failed horribly), then tried Ubuntu Server 13.04 and got the exact same problems as w/ Debian: After installing, the system doesn't show any boot-selection and tells me "Missing operating system". My setup is pretty simple: /dev/sdc - 1TB HDD (+ 3 other NTFS HDD) /dev/sdc1 - EFI, 100MiB, bootable /dev/sdc4 - ext4, 65GiB, Ubuntu/Debian (sdc2 & 3 are NTFS w/ data. Sorta lacking SATA-ports, therefore no OS-only HDD/SSD) Grub seems to be installed on /dev/sdc4, /dev/sdc1 only contains a "EFI"-folder. Not sure if thats correct. I used UNetbootin on OS X to make an 8GB USB-drive bootable and used the standard amd64-iso, running a perl-script wich eradicates a couple of naming-errors (different story). Using this tutorial and actually disabling UEFI and using legacy only dind't work either, the usb drive dind't even bother to boot. I'm pretty clueless here. I'd just like to install and use either Debian oder Ubuntu Server!

• Howto have thunderbird/lightning open ics files

  - by berkes

  Some websites offer .ics files, calendar files. I would like thunrbird to open these with Lightning so it can add the events in the ics-file to its calendar. When I use /usr/bin/thunderbird to open the file with, it starts a new message with the ics file attached. I could download the file, then import it from lightning, But I rather have lightning just open the file. Is there a commandline-option for this? Some wrapper-script maybe? Should I change something in firefox?

• How to auto-scan any plugged in usb storage device with clamav?

  I'd like to do an automatic virus scan on any plugged in usb device using ClamAV. I'm using Ubuntu 12.04. The closest thing I found was: Run clamav on mount of flashdrive How to run a shell script when a new USB storage device is detected? The first one is not working for me and the second one seems to target a known device. Is there a tutorial around I've missed? Or can I get some help with udev rules that apply to any usb storage device added? Currently nothing seems to do anything.

• Creating a curved mesh on inside of sphere based on texture image coordinates

  - by user5025

  In Blender, I have created a sphere with a panoramic texture on the inside. I have also manually created a plane mesh (curved to match the size of the sphere) that sits on the inside wall where I can draw a different texture. This is great, but I really want to reduce the manual labor, and do some of this work in a script -- like having a variable for the panoramic image, and coordinates of the area in the photograph that I want to replace with a new mesh. The hardest part of doing this is going to be creating a curved mesh in code that can sit on the inside wall of a sphere. Can anyone point me in the right direction?

• Do you know a good html mailing list management software with admin levels?

  - by SirG

  I'm basically looking for a program/app/script (can be commercial) which I can ideally install on a windows server (we can run asp, asp.net php mssql) we have different groups of people who send newsletters to web members, I want to bring it all into one app which I can monitor and control. Ideally it would be able to create html newsletters, (with some templates) track emails and click throughs. Manage email lists subscribe/unsubscribes. And importantly have different levels of admin, so a newsletter creator could log in and create and send off an email, it goes into a queue where a communications editor can have an overview of all newsletters and approve the sending of the emails or edit them before they are sent off. before I start coding something up myself I thought I'd ask if anyone has any advice! Cheers!

• Testing for disk write

  - by Montecristo

  I'm writing an application for storing lots of images (size <5MB) on an ext3 filesystem, this is what I have for now. After some searching here on serverfault I have decided for a structure of directories like this: 000/000/000000001.jpg ... 236/519/236519107.jpg This structure will allow me to save up to 1'000'000'000 images as I'll store a max of 1'000 images in each leaf. I've created it, from a theoretical point of view seems ok to me (though I've no experience on this), but I want to find out what will happen when there will be directories full of files in there. A question about creating this structure: is it better to create it all in one go (takes approx 50 minutes on my pc) or should I create directories as they are needed? From a developer point of view I think the first option is better (no extra waiting time for the user), but from a sysadmin point of view, is this ok? I've thought I could do as if the filesystem is already under the running application, I'll make a script that will save images as fast as it can, monitoring things as follows: how much time does it take for an image to be saved when there is no or little space used? how does this change when the space starts to be used up? how much time does it take for an image to be read from a random leaf? Does this change a lot when there are lots of files? Does launching this command sync; echo 3 | sudo tee /proc/sys/vm/drop_caches has any sense at all? Is this the only thing I have to do to have a clean start if I want to start over again with my tests? Do you have any suggestions or corrections?

• Managing .NET Deployment Configuration With Rake

  - by Liam McLennan

  Rake is a ruby internal DSL for build scripting. With (or without) the help of albacore rake makes an excellent build scripting tool for .NET projects. The albacore documentation does a good job of explaining how to build solutions with rake but there is nothing to assist with another common build task – updating configuration files. The following ruby script provides some helper methods for performing common configuration changes that are required as part of a build process.  class ConfigTasks def self.set_app_setting(config_file, key, value) ovsd_element = config_file.root.elements['appSettings'].get_elements("add[@key='#{key}']")[0] ovsd_element.attributes['value'] = value end def self.set_connection_string(config_file, name, connection_string) conn_string_element = config_file.root.elements['connectionStrings'].get_elements("add[@name='#{name}']")[0] conn_string_element.attributes['connectionString'] = connection_string end def self.set_debug_compilation(config_file, debug_compilation) compilation_element = config_file.root.elements['system.web'].get_elements("compilation")[0] compilation_element.attributes['debug'] = false end private def self.write_xml_to_file(xml_document, file) File.open(file, 'w') do |config_file| formatter = REXML::Formatters::Default.new formatter.write(xml_document, config_file) end end end To use, require the file and call the class methods, passing the configuration file name and any other parameters. require 'config_tasks' ConfigTasks.set_app_setting 'web.config', 'enableCache', 'false'
