      Hi,

      I think this is a development problem. I have tried everything
      obvious to get TFTP to work on F14 but to no avail. Could some one
      in the know look in to this please.

      I have tftp -server working on F14 and have done PXE
        Instillations using it. Since then I have done a yum update and
        ever since then have not been able to get it to work.

    Well you can run yum downgrade on the updates that you performed to
    nail down the one that potentially broke it.

      Below in the two posts are what I have tried, as far as I can
        see it is exhaustive.

      Many thanks in advance,

    Well posts or not here is a quick debugging guide for tftp which
    should tell you what's going on and note that using ip-aliase are
    broken in tftp as it seem to be in (x)inetd based services in
    general...

    Run 

    #tcpdump port 69 -v

    #touch /var/lib/tftpboot/my-test-file.txt

    #chmod 777 /var/lib/tftpboot/my-test-file.txt

    #tftp $IP
