The Common UNIX Printing SystemTM, or CUPS, is the software you use to print from applications like the web browser you are using to read this page. It converts the page descriptions produced by your application (put a paragraph here, draw a line there, and so forth) into something your printer can understand and then sends the information to the printer for printing.

If you want to access a remote file system through ssh you need to install sshfs.sshfs is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there’s nothing to do. On the client side mounting the file system is as easy as logging into the server with ssh.

Recently built an rpm for a client that needed to install nsis-2.29 on several redhat boxes. nsis-2.28 for centos/fedora is readily available at repo.calcforge.org .

I downloaded the centos source rpm and rebuilt it for redhat4 as described below:

I've had php4 running with apache2 for a while now and wanted to get php5 also simultaneously running. There are other ways to do this, but I opted with getting php5 to run as fastcgi and keep php4 as apache2 module so they can co-exist together.

This was done on CentOS release 4.5 with ISPConfig Control Panel on a dedicated hosting scenario. If you're looking to share the server with others then you might want to set up with suphp/SuExec for security purposes.

You can prevent automatic running of the GUI when you boot your debian machine by disabling your login manager be it KDM, GDM or XDM from running at boot time. To disable the login manager from automatically running at boot up.

I run the site on the open-source Drupal CMS and recently updated to the latest 4.7.7 version. The site has quite a few customizations and is not a standard install.

The html document root is a symbolic link to the actual drupal gunzipped folder and all other relevant custom modules are also just symbolically linked from the modules folder to keep the updates as simple as possible.

I also use the "bluemarine" theme which has been customized and named as "linuxweblog", so updates don't necessarily override my custom theme.

Pre-Update Preparation:

1. Backup database and site files.
   
2. Login to website as the administrator.
   
3. Disable the "Tag Cloud" block as it has some custom php.

Update:

1. `cd /var/www/`
   
2. Download from http://drupal.org/project/releases
   
3. Untar the gzip package.
   
4. `rm html` -- remove the symbolic link.
   
5. `ln -s drupal-* html` -- link to the newly extracted folder.
   
6. `cd html`
   
7. Edit the "sites/default/settings.php" file
   • Add the correct database, username and password to $db_url
     
   • Edit the $base_url without trailing slash to http://www.linuxweblog.com
8. Go to linuxweblog.com/update.php and run the update.

Post-Update Customizations

1. `cp -a themes/bluemarine themes/linuxweblog
   
2. Copy or merge node.tpl.php, page.tpl.php and style.css to the linuxweblog theme folder.
   
3. Merge .htaccess file and bring over the old customizations.
   
4. `cp -a ../drupal-old-*/{robots.txt,favicon.ico} .`
   
5. `ln -s ../site_files/ site_files` -- create the symbolic links to where the cache and other static files are placed.
   
6. `ln -s site_files/cache/ cache` -- create the link to the cache.
   
7. `ln -s ../../drupal_contribs modules/custom_mods` -- create the link to the custom modules.
   
8. Enable the "Tag Cloud" block.
   
9. Re-apply the google search hack to the "search.module" .

Security:

1. `cd /var/www/`
   
2. Chown -R user:group drupal-*
   
3. Set the directory permissions: `find . -type d -exec chmod 755 {} \;`
   
4. Set the file permissions: `find . -type f -exec chmod 644 {} \;`
   
5. `chmod 640 sites/default/settings.php`
   
6. `chgrp apache sites/default/settings.php`
