  • How to setup a user account for a web application

    - by ximus
    Hi, What are the main guidelines to setting up a user account on a Linux machine for a web app? In my case it is a Rails application that does file management. First thing I can think of is to limit access rights to only the directories it needs. But how exactly should I go about this? Setup rights through a user group or a through the user's ownership of those directories. I have very little experience in user rights management. What else do I need to consider? I've heard of ACL's and SELinux, do I need to look into any of these to guaranty decent security for my simple web app? Any advice about this and anything not mentioned welcomed, Thanks, Max. I will be using Ubuntu.

  • Firefox 4 refreshes all tabs although no internet connection exists

    - by Maxim
    I have a problem since I updated to Firefox 4. With Firefox 3.x I could start it without a internet connection and almost all of my open tabs were still loaded. With this I was able to read my open sites in the train where I have no internet connection. This does not work in Firefox 4. If I launch Firefox 4 I see all my open tabs but the content is not available. It seems that the new version tries to refresh all tabs on startup. Is there a possibility to disable this behaviour? Thanks in advance. Regards Maxim

  • *Browsing* iTunes University

    - by Kristina
    I recently discovered iTunes U and have been downloading a number of lectures, but I'd like to find more stuff in areas I'm interested in and iTunes U seems to want none of it. When I select a category of content to choose from - let's say Science - Physics - the only choices for browsing I seem to have are "Featured" and "New and Notable." I've looked around online and discovered that even the "See All" for these sections only shows a subsection of the entire collection for that category. There doesn't seem to be a regular "Browse" option like you would expect to find in such an application. Or is there? Does anyone here know if there is such a feature and, if so, where I can find it?

  • How is my password sent across when I check gmails/access bank site [closed]

    - by learnerforever
    What encryption is used when my password is sent across in gmails/when I do online banking? RSA? DSA? Public-private key encryption?. In key encryption, which entity is assigned a public/private key? Does each unique machine with unique MAC address has a unique public/private key? Does each instance of browser have unique key? Does each user have unique private/public key? How does session key come into picture? How do machines receive their keys?

  • How do I backup Firefox add-on like "Fastdial" addon for a reinstall?

    - by danacon
    I am doing a new install of Firefox and over the years my Windows "roaming folder" I use for backup has gotten all clogged up from so many add-ons and crap... I want to backup just a couple Firefox add-on's, one is "Fast dial" How do I backup this add-on and its addresses for when I reinstall Firefox and the add-on, so It will go back to where it is now? Most add-on's have a backup feature like "too many tabs" bookmarks and such but fast dial doesn't? so How do I backup this add-on? and /or addons like it without a backup feature? Thanks in advance any help or options would be a big help. Dana

  • URL sniffer/downloader

    - by Ricket
    Some websites have Flash content that plays music or videos. Most of the time they don't show you the URL of these music or videos, but for example, you can sniff a YouTube webpage and find the flv file that YouTube is actually requesting and playing. Right now I'm using Orbit Downloader, which has a feature called Grab++ that does just this; you start it, and then you refresh the page, and it shows you all files of certain types (image, audio, video) that the webpage requests, and then you can select one or more and download and it downloads them. But, I don't like Orbit, it installs plugins and has the whole download manager thing which I don't really want. What is a good alternative program? I'm not looking for websites like kickyoutube.com, I want a URL sniffer I guess. HTTPGuideDog used to be my Firefox add-on that did exactly this, but it hasn't been updated even to FF3 (and yes I know I can hack it to load anyway, I'm looking for something natively available preferably). I vaguely know of WireShark but last time I used it, I believe it captures individual packets, which is a little too fine-tuned for me. I just want to be able to see what's happening, and download something that the webpage downloaded. Oh, and I'm using Windows 7. Linux probably has some fancy command-line tool, but it just won't cut it for me. :-\ Edit: Oh, and something free please. Feel free to mention paid solutions though.

  • How to unblock chm files - unblock button is missing

    - by Yoav
    I downloaded a CHM file. When I double click it it prompts me to open / save / cancel. Whether I open or save a new copy, the 'new' version will prompt the same open / save / cancel popup ad infinitum. Searching google it seems that Microsoft have deemed it right for security reason to block these files by default. The solution is to right click the file, and click the 'unblock' button at the bottom: The problem is that I don't have that button on my system: BTW, the button is also missing for .exe files.I'm using Win7 64bit. Any ideas?

  • Use Adblock to allow most ads on a site

    - by jrob
    I leave Adblock turned on for all sites by default. I allow ads on some sites. You can do this by adding an exception for a site that is allowed to show ads. This puts a site in the white list. However, I do not know how to allow most ads on a page, but block a specific ad. I am not even sure Adblock will do this. I believe it is all or none. If a site is in the white list, it appears that all other rules are ignored. Is there a way to allow most ads on a website, but still block specific ads?

  • Utilities to view web page as text only?

    - by Jim Bancroft
    Hi everyone, I'd like to view web pages as text only on occasion, without images or fancy css backgrounds appearing. Are there any Mozilla or IE plugins that allow this? I've used Readability, and it's not bad but it still downloads pictures. Just wondering what's out there. Thanks!

  • How to keep Windows 7 from sleeping while scanning the PC.

    - by D Connors
    So, I've been using Microsoft Security Essentials lately. And it usually takes a couple hours or more for it to full scan my hard drive. Because of that, I commonly leave it scanning while I go do something else. Problem is: 10 minutes later, windows 7 goes to sleep, and the scan is (obviously) paused. That's What I'd like to stop happening. So far, the only way I've been able to avoid it was to create a power plan, and switch to it while away, to keep the PC from sleeping. Problem is that I have to keep switching power plans and I'd like the PC to be able to go to sleep in case MSE finishes scanning and I'm still not back. Maybe I'm just asking for too much, but I've been surprised by the users here plenty of times already. So let me know if you know how to keep the PC from sleeping while MSE is scanning. Thanks

  • Apache server doesn't create directory or file under www-data user [duplicate]

    - by Harkonnen
    This question already has an answer here: What permissions should my website files/folders have on a Linux webserver? 4 answers very newbie to Apache here I installed Apache 2.4 on my Arch server where I installed newznab (a newsgroups indexer). I have noticed that all files newznab needs to create are created under my login user, and not apache default user (www-data). I read here that it's bad security practice to allow www-data to write files. I agree. But as an apache newbie, I would like to know where (in the httpd.conf I suppose ?) the user allowed to write files can be configured, because I want another account to be allowed to write files instead of my main account.

  • How important is patch management?

    - by James Hill
    Problem I'm trying to sell the idea of organizational patch/update management and antivirus management to my superiors. Thus far, my proposition has been met with two responses: We haven't had any issues yet (I would add that we know of) We just don't think it's that big of a risk. Question Are there any resources available that can help me sell this idea? I've been told that 55-85% of all security related issues can be resolved by proper anti-virus and patch/update management but the individual that told me couldn't substantiate the claim. Can it be substantiated? Additional Information 1/5 of our computers (the ones on the building) have Windows update turned on by default and anti-virus installed. 4/5 of our computers are outside corporate and the users currently have full control over anti-virus and Windows updates (I know this is an issue, one step at a time).

  • Configure Iptables to allow a PHP-app accessing a port-nr

    - by Camran
    I have a php-application which connects to another app called Solr (database search engine). I can via this php app add/remove documents (records) from the Solr index. However, the Solr security is low, and anybody with the right port nr can access Solr and remove documents (records). I wonder, is it possible to ONLY allow my own php-app to have access to Solr somehow? Prefferably via Iptables. I am thinking I can only allow my own servers IP to that port, and it would solve my problem, because PHP is a server-side code. But I am not sure. About the Php-app: The website is a classifieds website, and when users wants to add or remove classifieds, they do so through a php app, which is this one. The app has a function which connects to solr and updates the database (index). I appreciate detailed answers... Thanks

  • What is the best way to setup a public and private wireless access point on the same home network?

    - by Dougman
    For my home network (with internet provided from a cable modem) I would like to setup a secure wireless access point that I use for all of my personal connections (home PC, iPhone, Xbox, etc) and also another public access point that friends and folks in the neighborhood may connect to (for good karma). I want to ensure that my private traffic cannot be accessed from users of the public access point. I currently have one router that is running the Tomato firmware that I use with WPA security. What is the best way to accomplish this kind of setup securely (if it is possible in a home environment)?

  • TLS-SRP ciphersuites support in browsers

    - by dag
    i'm doing some research on how browsers support TLS-SRP (RFC5054). I know that TLS-SRP is implemented in GnuTLS, OpenSSL as of release 1.0.1, Apache mod_gnutls, cURL, TLS Lite and SecureBlackbox. I don't find any fresh source of information, only this from 2011: http://sim.ivi.co/2011/07/compare-tls-cipher-suites-for-web.html I'm testing them manually at the moment, but as far as i know nobody seems to support it. My interest is then in understanding if browsers are planning to support these ciphersuites in the future, apart from the current state. Actual findings (i'm sorry i can't include more than 2 links): Firefox: BugZilla bug id: 405155 IE: Microsoft connect Bug ID:788412 , date:22/05/2013 (closed) Chromium/Chrome: the interesting work by quinn slack http://qslack.com/2011/04/tls-srp-in-chrome-announcement/ Chromium code review: 6804032 Any other help?
