About CentOS:

The Community ENTerprise Operating System (CentOS) is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor. CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) The CentOS Project is the organization that builds CentOS.

" + "

For information on CentOS please visit the CentOS website.

" + "

Note:

CentOS is an Operating System and it is used to power this website; however, the webserver is owned by the domain owner and not the CentOS Project. If you have issues with the content of this site, contact the owner of the domain, not the CentOS project." + "

Unless this server is on the CentOS.org domain, the CentOS Project doesn't have anything to do with the content on this webserver or any e-mails that directed you to this site.

" + "

For example, if this website is www.example.com, you would find the owner of the example.com domain at the following WHOIS server:

" + "

http://www.internic.net/whois.html
