I'm so stupid you have no idea !!
After looking into the data I was able to gather from the snoop, I saw a ISC
3.0.5 in it !!
Guess what on of my server was runing 3.0.5 and the other 3.1.0
So after installing the right version the 2 start start just like a snap of
of a finger
That can be changed in the /var/adm/messages in case of different version
the dhcpd should report what it has and what it expect instead of timeout or
connection close, don't you think ?
anyway, thanks for you help and sorry for this stuppid things !!!
