  1. sudo rake snorby:setup
    Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 0.9.2. Prepending `bundle exec` to your command may solve this.

    Please tell me how to solve this. I have tried bundle update and bundle exec but no luck ;/

    • Muhammad Attique

      first remove currently installed rake version by:

      # gem uninstall rake -v 10.4.2

      check if this works, if not, install rake with command:

      # gem install rake -v 0.9.2

      it should fix the version issue.

  2. I want sudo service apache2 restart

    apache2: Syntax error on line 234 of /etc/apache2/apache2.conf: Cannot load /var/lib/gems/1.9.1

    /gems/passenger-5.0.13/ext/apache2/ into server: /var/lib/gems/1.9.1

    /gems/passenger-5.0.13/ext/apache2/ invalid ELF header


    How can I fix it

  3. Submitting Credentials, Pleas Wait… is continue how can I fix?

    • Muhammad Attique

      Sorry, I could not understand, where are you facing this error at.? Can you please give more details or better if screenshot.?

  4. rake snorby:setup generates error: “/usr/bin/env: ruby: Permission denied” . Any ideas, Muhammad? [Running Ubuntu 14.04] Thanks

    • are you executing command with “sudo” in the beginning. normally Permission Denied error is faced due to limited permissions on ubuntu/debian hosts’ users and they need to execute every system level command with “sudo” in the beginning.

  5. Thx bro just wondering after snorby been installed does it need any rules or any thing? I installed snorby in my Kali machine it does not start until I run sudo service mysql restart and sudo service apache2 restart and when it start all the default values are 0. I don’t know if I need to play with administration or events?

    • Hi, You are welcome.
      No further configuration required for auto-start of Snorby. You may need to verify that apache and mysql both are started and executed fine on every start by hosting a test website.

      • Thank you for reply, what do u mean by hosting a test website? Do you mean I should set up a host website?

        • Hi,
          Yes, just like you’ve hosted Snorby in Apache along with MySQL DB, I’m asking you to host another website to test if Apache & MySQL are working fine and issue is with Snorby only.

  6. Hi! Thx for this guide. I’m having problems installing rake. I get this error:
    ERROR: While executing gem … (URI::InvalidURIError)
    URI must be ascii only “?gems=u{2013}version=0.9.2”

    I’ve been googling but can’t find any solution that works.

    I tried to do the next step and then I got the following error while running:
    sed -i s/”/usr/local/bin/wkhtmltopdf”/”/usr/bin/wkhtmltopdf”/g’ /var/www/snorby/config/snorby_config.yml

    sed: -e expression #1, char 11: unknown option to `s’

    I can’t find any solutions for these problems and would appretiate if someone know how to fix this!

    • Muhammad Attique

      Which version of Rake are you using/installed ?

      Try to uninstall Rake with following command:

      # gem uninstall rake

      Now install rake with command:

      # gem install rake -v 0.9.2

      it should fix the issue.
