After Googling it seems. It seems also versions prior to 0.99 are
bugged. But as it's a 1.87 should be ok.

Did a "sudo apt-get install tftp-hpa" then a "tftp localhost" and got
a connection. Seems to be ok.

I see some tftp request from 192.168.0.250 (the IP given to the client
by dhcp3server

but no boot on client ....

is my capture of tcpdump (sorry, some Google request from gMail, and
nntp updates from nntp client)
