Linux has always trailed behind it and although most of the technology to rival Microsoft has been in place, it has always been a mammoth task to setup a server from scratch  to do that.  ClearOS came to fill in this gap.

“ClearOS is a powerful network and gateway server designed for small organizations and distributed environments.  Though ClearOS comes with an extensive list of features  and integrated services, the solution is easy to configure thanks to the intuitive web-based interface.” (extracted from Clear Foundation website)
 
Take a look at how ClearOS’ features match the MS SBS:

Microsoft SBS

Centralized Authentication (Active Directory)
Mail, calendaring and instant messaging (Exchange)
Webserver (IIS)
Firewall (ISA)
Content management system (Sharepoint)
Antivirus (Forefront)
Database (MS-SQL Premium version only)
Remote Desktop Services
Virtual Private Network (VPN)

 ClearOS Linux

Centralized Authentication (LDAP)
Primary Domain Controller (Samba)
File and Print Services (Samba and CUPS)
Mail (SMTP, POP, IMAP, Webmail)
Calendaring (Kolab groupware)
Webserver (Apache)
Firewall plus intrusion protection (iptables, Snort)
Antimalware (Clam Antivirus, Antiphishing, Antispyware)
Antispam (Spamassassin)
Database (MySQL)
Virtual Private Network (IPSec, OpenVPN, PPTP)
Web Proxy (Squid)

The Linux Magazine published an in depth article comparing and explaining this “new” Linux distro.

This file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

This 301  Redirect can be used anytime you want to redirect a URL. Here are some examples of its use:

  • Single page – Redirect 301 /old_page.html http://www.mysite.com/new_page.html
  • entire site -   Redirect 301 /  http://www.new_site.com/
  • change file extension (html to php in this case) -  RedirectMatch 301 (.*)\.html$ http://www.mysite.com$1.php

There are many other uses for Redirect 301 and mod_rewrite on Apache, if you are moving a site or redesigning a site with a new CMS make sure you redirect your old URLs to your new site. By failing to do so any user that clicks on a link to your old site (page) will hit a 404 ERROR page, this will affect your search rankings. 

The book “Professional SEO” has a good chapter in mod_rewrite and URL redirection, and is also great SEO manual

For a full tutorial on .htaccess visit the official Apache website.
