I have tried running tftp on the Server
using the IP address ( so I believe no need for DNS ? )
cd tftptest
tftp
tftp>connect 192.168.1.3

get /etc/dhcpd.conf
Transfer timed out
tftp>quit
and nothing else to show anything happening
in /var/log/messages
so I think we are getting nearer to the root of the problem.
Any ideas?
