Hey what are the best websites to get free software for linux. Thanks.

What sort of software are you looking for?

SourceForge.net provides a rallying point for many open-source projects, though of course all the major applications and distros have their own sites.

Audio and video software and also general software which provides 'how to install' guide also. Thanks.

The best sites are generally the repositories for your distro.

In linux usually you don't go fishing software around the web unless you have a very specific need and your distro can't fill it.

You should use the package manager of your distro and install everything from there. You don't need howtos or the like.

If you really like to navigate the web, you can use sourceforge or freshmeat, but after you find a program, if you want to try, search it in your package manager because most likely it's there, and install it from there. If you install things out of your package manager you are asking for trouble.

sourceforge.net
tucows.com
savannah.gnu.org
gnome.org
kde.org

Never mind.

http://www.google.com

That's usually where I start. then I use search terms such as GPL or OPEN SOURCE as part of my query

GPL network monitoring
GPL ERP
Open Source ERP
open source CRM
open source project management
etc..
