  • How to append to a file as sudo?

    - by obvio171
    I want to do: echo "something" >> /etc/config_file But, since only the root user has write permission to this file, I can't do that. But this: sudo echo "something" >> /etc/config_file also doesn't work. Is there any way to append to a file in that situation without having to first open it with a sudo'd editor and then appending the new content by hand?

  • How to let mod_wsgi only handle certain URLs under Apache?

    - by Frederik
    I have a Django app that handles "/admin/" and "/myapp/". All the other requests should be handled by Apache. I've tried using LocationMatch but then I'd have to write a negative regex. I've tried WSGIScriptAlias with the /admin/ prefix but then the wsgi_handler receives the request with the /admin/ part cut off. Is there a cleaner way to make mod_wsgi only handle certain requests?

  • Is there a program that can colourize the output of any linux command?

    - by BeeBand
    Or would I have to write my own? What's the best language for building a tool of this kind? I'm kind of new to linux, but I'm guessing that you could pass the output of a program to a particular script and have it display it in various colours, based on some regular expressions (constructed from some kind of config file perhaps). Or has it been done already...?

  • Pasting images into gmail from clipboard, shows fine when sent, but arrives as text

    - by John Robertson
    I have had consistent problems with pasting images into Gmail. I use Firefox (just in case that is relevant, but I wouldn't expect so). The image displays fine as I write it. But when it arrives at my family members Gmail account, it is being displayed in some base64 encoded form as many pages of text with a beginning like: img src="data:image/png;base64,iVBORw0KGgoAAA..... On the receiving end I cannot get the images to display properly.

  • Ubuntu Software RAID 0 on AWS Does Not Survive Reboot

    - by Eric J.
    I'm experimenting with creating a software RAID 0 device from 4 EBS volumes on Ubuntu 9.10 running at Amazon AWS following this guide: http://alestic.com/2009/06/ec2-ebs-raid The device appears (and according to SysBench is 3.5x faster than a regular attached EBS volume). Problem is, when I reboot the instance, all files on the RAID device are gone. The device is available and mounted where expected, but contains no files. I am able to write new files to it, which survive until the next reboot.

  • Cloning Windows 7 to Another Machine

    - by trobrock
    I am trying to clone a Windows 7 Install from one machine to others, in a computer lab situation. I have used clonezilla to make an image of the machine's harddrive and then attempted to write that image to a second machine's disk. Everything went fine, but when I try to boot Windows 7 on the second machine I get a blue screen flash and then it tries to run the startup repair tool, which runs unsuccessfully. Is there something new with Windows 7 that keeps it from being cloned like this?

  • Do you know of any alternative to "Google App Engine"?

    - by brilliant
    On their presentation of "Google App Engine" Google team members boldly said: "You write a code and we will run it for you". Then the "Google App Engine" was launched and it still does its job quite successfully - "Google App Engine" runs millions of applications of different sizes belonging to different users completely free!!! Now, here is the question: Do You know of any alternative to GAE? Have You ever even heard of any such service out there that would run Your Python code for free?

  • Is adding users to the group www-data safe on Debian?

    - by John
    Many PHP applications do self-configuration and self-updating. This requires apache to have write access to the PHP files. While chgrp'ing them all to www-data appears like a good practice to avoid making them world writable, I also wish to allow users to create new files and edit existing one. Is adding users to the group www-data safe on Debian? For example: 775 root www-data /var/www 644 john www-data /var/www/johns_php_application.php 660 john www-data /var/www/johns_php_applications_configuration_file

  • SSD has 32-bit Win 7 Ult.; partition now both unformattable and undeletable.

    - by user33666
    Drive 0, Partition 1 can't be deleted or formatted, at least by using the HD drive bay and attempting a delete or format with the 32-bit Win 7 CD. Most of my data is still on it and available for read/write (where the drive isn't occasionally pocked with "unrecoverable" or "corrupted" files). I've just never heard of a condition where the HD cannot be formattable. I now just have a very expensive backup drive that's got Swiss cheesed areas. The thing doesn't accept a Windows 7 repair or reinstall either.

    I am new to linux. I have a server that I have successfully installed Debian Lenny on and everything else needed for a LAMP server. But I am unsure how to setup FTP. My first attempt went horribly wrong had a load of permission issues. How can I give full read/write access to my WWW folder. The more in-depth the answer the better. I feel like such a noob.

  • Suggestions for splitting server roles amongst Hyper-V virtual servers / RAID6 or RAID10? / AppAssure

    - by Anon
    We have 2 Hyper-V hosts at present running 1 virtual server that was converted from a physical box running all roles. My plan is to split the roles over various virtual machines, upgrading to the latest software versions as I go, and use the backup server as a standby in case the main server fails. AppAssure backup software has a feature called Virtual Standby, so the VHD's can be ready to be fired up on the backup server if necessary. Off-site backups will be done via external USB drive for now. I'm just seeking some input/suggestions into how I'm planning to split the roles out amongst various virtual servers. Also, I'm curious how to setup the storage on the servers. We do not have any NAS's, SAN'S or any budget for this. What would the best RAID level be to use? I'm thinking either RAID6 (which is currently used) however I'm concerned about the write speeds, or RAID10 but again I'm worried that I can only lose 1 drive (from the same mirror) as opposed to any 2 with RAID6. I realise I have a hot swap for this, but what if a further drive fails during a rebuild? Is the write penalty of RAID6 worth the extra reliability over RAID10? Or will it be too slow with all the roles I am planning, therefore RAID10 is my only real option? The reason for the needed redundancy is I am the only technician and I'm not always on-site. Options I've considered: 1) 5 drives in RAID6 set, 200gb for host OS, rest for VM storage. 1 drive for hot swap - this is how it is currently setup 2) 4 drives in RAID10 set, 200gb for host OS, rest for VM storage. 2 drives for hot swap 3) 4 drives in RAID10 set for VM storage, 2 drives in RAID1 set for host OS. No drives for hot swap - While this is probably the best option with the amount of drives I have, I don't like the idea of having no hot swap 4) 3 drives in RAID6 set for VM storage, 2 drives in RAID1 set for host OS. 1 drive for hot swap All options give us enough storage capacity for our files, etc. We don't have any budget for extra drives or extra hot swap HD chassis for the servers. We have about 70 clients and about 150 users.
