I am trying to replace Windows by Ubuntu, because Linux simply rocks. :-) So I am on the quest finding appropriate alternative software for ubuntu, that I used on Windows (or sometimes Mac) so far.

On the Mac you have UNISON, a really great tool - perhaps the best client I ever saw. On Windows I used GrabIt, not as beautiful as UNISON, but gets the job done.

But now I'd love to read about some propositions for Ubuntu. Which client would you recommend? I'd like to read about about clients which have a GUI as well as about terminal client, that don't need too much everytime terminal configuration or in other words black magic executed while fulmoon using the foot of a crow and a pregnant earthworm and while circling counterclockwise, chanting some spell on elvish... ;-)

By te way: SSL support would be great!
