When done, it'll look a whole lot like the "Troubleshoot TFTP" article in structure.

Testing FTP

[administrator@D620 ~]$ ftp
ftp> open 10.0.0.3
Connected to 10.0.0.3 (10.0.0.3).

Troubleshoot FTP

Troubleshooting here.

Disable/verify Firewall

Disable & Stop Firewall in Fedora 20/21

systemctl disable firewalld.service

systemctl stop firewalld.service

Can be undone with "start" and "enable".

Check Firewall in Fedora 20/21

systemctl status firewalld.service

Fedora 16

Add /bin/bash to /etc/shells as the vsftpd yum install does not do it correctly causing tftp timeout message

Check Firewall in Debian/Ubuntu

sudo iptables -L

If disabled, the output should look like this:

Chain INPUT (policy ACCEPT)
target prot opt source destination 

Chain FORWARD (policy ACCEPT)
target prot opt source destination 

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Disable Ubuntu Firewall

sudo ufw disable

Disable Debian Firewall

iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

Temporarily disable Windows firewall
