FTP: which FTP is best for Ubuntu to upload rails project

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
https://lists.ubuntu.com/mailman/listinfo/ubuntu-users 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.
