This looks more like an issue in the OS / configuration, than Cuberite itself. First of all, verify that the ports are really open on the machine - use the "netstat -nlat | grep 25565" command to see if the minecraft game port is really open, and on what interfaces.
I'm not sure if Linux is case-sensitive about hostnames, but usually "localhost" is written with lowercase l at the beginning.
Are you trying to connect to the server from the same machine, from another machine on the same LAN, or from the outside internet? If from the same machine, there isn't much that would get in the way, other than the port not really open. If from the same LAN, it could be some firewall issue on either machine (check with "ping" if the machines can see each other, check with wireshark on each where the communication on port 25565 is getting lost). If from the outside internet, it could be really anything, from a firewall to NAT rules to your ISP blocking the port.
