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

Testing FTP

Try to get a file with Linux:

To explain what's happening below,

These commands are NOT done on your FOG server, they are done on another Linux machine (this example uses Fedora).

Create a test file with some data in it to send later.

Start ftp (may need installed first).

Open connection to FOG server.

Provide username.

Provide password.

Change to /images directory.

List directory contents.

Upload file.

List directory contents to verify.

Download the file.

Delete the file.

Exit 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
