I am trying to upload the constants to my shared server but built in FTP in Ubuntu is not working
You might be better posting this in a Ubuntu support list such as ubuntu-users Info Page as it does not appear to be a RoR issue.

I use Filezilla (sudo apt-get install filezilla). Supports ftp,sftp, etc

Investigate whether you can ssh up to your shared server. If you can then I suggest you invest a little bit of time to set up capistrano deployment via ssh and at the same time use git too. It will save you so much time.
See http://www.capify.org/index.php/Capistrano
