VPN avec Ipsec

Bonjour,

Lorsque je lance cette commande j'ai les erreurs suivantes :

[root@localhost etc]# /usr/sbin/ipsec verify
Checking your system to see if IPsec got installed and started correctly:
Version check and ipsec on-path [OK]
Linux Openswan U2.4.9/K2.6.23.15-137.fc8 (netkey)
Checking for IPsec support in kernel [OK]
Testing against enforced SElinux mode [FAILED]

SElinux is running in 'enforced' mode. Since no working SElinux
policies exist for Openswan, SElinux should be disabled.

echo "0" > /selinux/enforce (or edit /etc/sysconfig/selinux)

NETKEY detected, testing for disabled ICMP send_redirects [FAILED]

Please disable /proc/sys/net/ipv4/conf/*/send_redirects
or NETKEY will cause the sending of bogus ICMP redirects!

NETKEY detected, testing for disabled ICMP accept_redirects [FAILED]

Please disable /proc/sys/net/ipv4/conf/*/accept_redirects
or NETKEY will accept bogus ICMP redirects!
