Edubuntu 14.04.1 updates break TFTP

[Joseph Bishay]

Hello,

I had the same problem with a clean install of Edubuntu 14.04 LTS.

For some reason, even though tftpf-hpa is running, it was not
responding to any of thin clients.

I solved it by running sudo service tftpd-hpa restart.  Then the
clients connect no problem.

I obviously can't type this in each time, so I added it to
/etc/rc.local so it runs each time the server reboots.  And the
problem went away.

I don't know if that's the correct solution, but I know it works.

I hope that helps
Thanks
Joseph
