1. May be due to iptables or other firewalls. Try turning off the firewall and then ftp.
For turning off iptables, do /etc/init.d/iptables stop

2. SSH keys are not setup (Search for "passwordless ssh" in unix.com/google) or the SSH daemon is not running.
Code:
[root@bt]ps -eaf | grep sshd
root      1987     1  0  2010 ?        00:00:00 /usr/sbin/sshd

To start the ssh daemon /etc/init.d/sshd start

3. Same as 1.

Make sure the ftp daemon is running on the server. Mine is vsftpd.
Code:
[root@bt]ps -eaf | grep ftp
root      2083     1  0  2010 ?        00:00:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf

To start the ftp daemon
/etc/init.d/vsftpd start
