again,,:(

root@pc62:~# sudo sysctl -a | grep ipod
error: permission denied on key 'net.ipv4.route.flush'
net.ipv4.icmp_ipod_version = 2
net.ipv4.icmp_ipod_enabled = 1
net.ipv4.icmp_ipod_host = 2147483647
net.ipv4.icmp_ipod_mask = 2147483647
net.ipv4.icmp_ipod_key = fca4b3328257112088c3188fb66be36d
error: permission denied on key 'net.ipv6.route.flush'

by the way... why is the net.ipv4.icmp_ipod_host and 
net.ipv4.icmp_ipod_mask the same value ??
