Try
# tftp <hostname>
then make sure you are connected
# status
then just
get <path to filename>
see if you can do that - if not tftp could be mis-configured in inetd.conf or you dont have a windows tftp server -
The tftp line should look something like this -
# TFTPD - tftp server (primarily used for booting)
tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd
If you have to change it I suggest a reboot afterwards - HUP-ing inetd sometimes does not work
You will also need a Windows tftp server - it does not have one - I like
http://www.solarwinds.com/downloads/index.aspx - and use the FREE tftp server - you will need to download - install - start - and then configure because you might want to change the default directory that is shared out ( C:/TFTPBOOT is the default) make sure to click on the security tab and change it too - transmit and recieve -
If you set them both up right you should be able to tftp between both machines -
I had a problem like this with one of our machines this week and the inetd.conf was the problem - I hope this helps -
