Tftp timeout....

If you get this issue, do the following:

Fedora 9

service iptables stop 
service ip6tables stop 
 
chkconfig iptables off 
chkconfig ip6tables off

Fedora 16

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

Other Troubleshooting

From your FOG server test out tftp

tftp -v X.X.X.X -c get pxelinux.0

From a Windows PC run at the cmd prompt:

tftp x.x.x.x get pxelinux.0

If tftp & xinetd are running your should get:

Received XXXX bytes in X.X seconds....
