  *> Hello all
  *> 
  *> I am using RSVP and CBQ with Linux, and I have some 
  *> questions.
  *> I have the system: sender <--> router <--> receiver
  *> and I have installed:
  *> 	Router:	SuSE 6.3, kernel 2.2.13
  *> 	Sender, receiver: Red Hat 6.0, kernel 2.2.12-14
  *> 	and the packets:	iproute2-current.tar.gz
  *> 				rsvpd.rel4.2a4-1.tar.gz
  *> 
  *> a) Why if I start the rsvp daemon like root it doesn´t 
  *> do UDP encapsulation, and if I start it 
  *> like a user it do UDP encapsulation ? (it happens in 
  *> the 3 machines)
  *> 
  *> root: # rsvpd -D
  *> 
  *> 	RSVP Version 4.2a4, Compiled....
  *> 	Log level:7  Debug mask:7  Start time....
  *> 	IPv4 Multicast Daemon is not running
  *> 	Physical, Virtual...
  *> 	.
  *> 	.

  *> 	RSVP Version 4.2a4, Compiled....

  *> 	IPv4 Multicast Daemon is not running
  *> 	Using UDP encapsulation			(<--- 
  *> ¡¡ HERE  !!)
  *> 	Physical, Virtual...
  *> 	.
  *> 	.
  *> 	T1>
  *> 
  *> 
  *> 
  *> 	Does it refer with Multicast ?
  *> 
  *> 
  *> b) If I compile the rsvp daemons with option -DCBQ in 
  *> the Makefile of rsvp, I obtain:
  *> 
  *> 	sender: send PATH messages
  *> 	receiver: receive PATH messages
  *> 	receiver: send RESV message
  *> 	router, sender: when RESV arrive, the rsvp 
  *> daemon does`t work, and appear the next
  *> 		message in rsvp.log

  *> 
  *> 
  *> c) The class 1:7fff has 1Mbit (with CBQ), I do a

  *> reserve it. It is OK. After I do a reserve of any size 
  *> that add with the previous reserve 
  *> overflow the 1Mbit, the daemon in router and after in 
  *> the sender don`t work. In the monitor
  *> appear:
  *> 
  *> 	RTNETLINK error: Unknown error 4294967100 
  *> get_stats Segmentation fault
  *>
