Solved issue -Directory index forbidden by Options directive:

I want to change the default location of Apache folder which is (var/www/html).
I am using the Fedora as OS and apache 2 here. you can use following code with any linux box like centos or ubuntu. Here we solved the issue of directory.

When I inserted the following code in bottom of the httpd.conf file.
<VirtualHost *:80>
Options +FollowSymLinks
ServerAdmin siwan@yahoo.co.in
DocumentRoot /var/www/html/testfolder
ErrorLog logs/error_log_net
TransferLog logs/access_log_net
</VirtualHost>

When tried the http://localhost/ in browser, I got the default browser page.
Then I tried to look my apache error using following command:
#[root@localhost ]# tail -f /var/log/httpd/error_log

In apache error log I got following error.
[Wed Oct 07 15:59:50 2008] [error] [client 127.0.0.1] Directory index forbidden by Options directive: /var/www/html/testfolder/

I changed the AllowOverride option but nothing is happens. Then I read the welcome page text
“To prevent this page from ever being used, follow the instructions in the file /etc/httpd/conf.d/welcome.conf.”
I opend the welcome.conf file.

I found following lines in welcome.conf file.
<LocationMatch “^/+$”>
Options -Indexes
ErrorDocument 403 /error/noindex.html
LocationMatch>

I changed that to as follows:

[viral-lock message=”Solution code is Hidden! It’s Visible for Users who Liked/Shared This article on Facebook or Twitter or Google+. Like or Tweet this article to reveal the content.”]

<LocationMatch “^/+$”>
Options Indexes
ErrorDocument 403 /error/noindex.html
</LocationMatch>

[/viral-lock]

That solve my problem. Some time your selinux will cause the issue so you need to deactivate the selinux.
Some time File permission will also cause the issue.
You can change the file permission using following command, go to that directory and run following command.
#chmod 777 *

You can use above commands on any linux box. Ubuntu, centos, redhat or on fedora box.. still solution will be same.

Share Thunderbird Between Windows and Linux

Many people are using Thunderbird as a email client.

I am using the Windows xp and Fedora 8 (Dual boot OS) on my System. Two years back i was using Microsoft office Outlook for viewing the emails.

Later on i need to work on Linux also. For email check i always i need to go or restart the system and start the Outlook.

Then i moved to Thunderbird which is Open source and free. Important thing is Thunderbird works on Linux and windows both.

My Tip :Share Thunderbird Between Windows and Linux

I installed the Thunderbird for Windows. First save all settings. Then follow my steps:

1. Open Thunderbird ->Click on Local Folders button(Top left button)

2. Choose or click on-> View settings for this account

3. Choose or click on-> Local Folders

4. First go that location by browsing the explorer and copy the folder and paste into your d:  drive.

5. Restart the thunderbird.

fetch svn project without svn files and without deleting

I worked with any technologies and languages. Many times we need some folder or codebase for your new project.
So we need to copy old project code or folder in our new project. In rails we need many plugins for our project. Some times few plugins are not getting installed in our project.

fetch svn project without svn files and without deleting

Few days back i tried to install acts_as_solr plugin in my project. I got an error. So i coppied acts_as_solr plugin from my old project and pasted in new project.

When i tried to SVN commit the files in the new project. That files started commiting to Old project.
So i need to remove all .svn folders form all the subfolders. Than only i can add all the folder to new project.

I google around for solution. I found many ways:

  • Remove the all .svn folder from all subfolder.
  • Through linux command find all .svn file and delete. (but i think this harmful)
  • SVN export – command

SVN export is the very simple and reliable way to fetch project out of svn.
In windows, using svn export is very easy.

setting up basic authentication apache

Two months back, we got the requirement of do basic authentication for testing site server. We given steps and code for setting up basic authentication apache. So Google or any search engine site cannot index the testing sites.

setting up basic authentication apache

We are using Fedora as Operating System and Apache as web server on our testing machine. We hosted more than fifteen test sites on that server.

I successfully created basic authentication on server.

Use following commands:

#su

#ROOT_PASSWORD

#vi /etc/httpd/conf/httpd.conf

in that file you need to insert following lines.

AccessFileName htaccess.acl .htaccess

# htpasswd -c /home/USER/pwd.txt USER(you can define your user of stystem.)

New password: mypassword
Re-type new password: mypassword

That sit. Your username and password is set for popup.

Now you need to only create or update your .htaccess  file. You can create or find .htaccess file in your project folder.

Use or copy and paste following code in that file: (.htaccess file)

AuthUserFile /home/USER/pwd.txt
AuthName "Protected"
AuthType Basic


require valid-user

I following exact method for my server and projects. It is working perfect for me.
