best way to check all links on a domain or website?

I need to get a list of all the links on an entire website and check that they work.

What is the best tool for this? This is a one time thing so I am looking for freeware.

Thanks

 

Here's an online tool for that. It only checks one page at a time.

That looks like it only checks backlinks. I need to check all the links on our domain.
