Starting racoon

[Liloulinx]

Hi every body,
I would like use IPsec between two machines (10.172.5.19 
<http://10.172.5.19> and 10.172.52.78 <http://10.172.52.78>). So I have 
configured them(manually configuration). When I try to ping the second 
machine from the first I have this message:
"connect: No such process".
This does mean that racoon is not running on this machine. When I try to 
run it, it give me this answer:

[root at PC-UNIX-a34-U-sys3 ~]# /usr/sbin/racoon -F -d -f 
/etc/racoon/racoon.conf
Foreground mode.

Can you help me to resolve this problem?
