It's all you brother.  Was looking for someone to take it on.  Can we
post this to the main dev list?

Alex

Can you repost to dev@d.a.o list with your original comments to
me

That's great Evgeniy.  Why don't you start looking at the code that 
already exists if you have not already.  It's a good start.  Feel free 
to start contibuting patches for the code that is already there.  Or 
express your approach/plans for discussion on this list.

DHCP is very important.  Also note that you can embed the ApacheDS core 
with backing store without exposing any oither protocols even LDAP if 
you like.  So this scenario == standalone configuration of only a DHCP 
server.  You get a free backend and a frontend (almost) in MINA. 

Thanks,
Alex

I want to realize not only DHCP protocol, but fully worked DHCP-server
for ApacheDS or for standalone use.

To send broadcast or multicast packets in NIO:
 aDatagramChannel.socket().setBroadcast(true) ; // set broadcast flag
 aDatagramChannel.send(aByteBuffer, new
InetSocketAddress("255.255.255.255", PORT) ;

On Linux system, without default router, sending broadcast packets 
throw "Network is unreachable" exception. This apply to BIO too. The
broadcast messages sending only on interface that have default router.

May I put multicast or broadcast address to MINA via
Session.setAttribute(..) method?

 Sounds interesting. We don't have any DHCP support yet. Most protocol stack 
is built upon MINA (a network application framework). MINA currently 
supports only NIO transport (which doesn't support multicast). You'll have 
to implement BIO (old socket I/O) support for MINA and then build DHCP 
protocol on top of MINA. Then integrating protocol with ApacheDS will be 
great.

Thanks,
Trustin
