Are there any download managers with web interface? [duplicate]

Im new to ubuntu server , im using a personal home server and i want to install a download manager through terminal. On windows i have been using jdownloader on which i was able to use my accounts on "downloading" sites like rapidshare , easybytes etc..

I read that jdownloader can be installed on ubuntu but only via desktop/gui. Is there any download manager like jdownloader but with webinterface? so it will be easy to use?

Thank you
