What Unix platform do you have?

Most Unixes have tftp servers already there. For example, under FreeBSD you
can just uncomment this line from /etc/inetd.conf:

tftp   dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -l -s /tftpboot

Then:

    # killall -1 inetd
    # mkdir /tftpboot

If you want to *upload* files to the tftp server, you'll either need to
create them first with the correct name: e.g.

    # touch /tftpboot/ios123
    # chmod 666 /tftpboot/ios123

or else add the '-w' flag to the tftpd command line in inetd.conf.

Note that tftpd is very insecure - no passwords are used when uploading or
downloading files! So you probably should use /etc/hosts.allow to limit
access to certain IP addresses. Or else disable tftpd when you've finished
using it.
