Why is /proc/net/nf_conntrack empty?
Clash Royale CLAN TAG#URR8PPP
0
On my RHEL 6.5 I expected /proc/net/nf_conntrack to contain the latest/current connections but it is completely empty:
[root@plop ~]# cat /proc/net/nf_conntrack
[root@plop ~]#
Can you help me understand why?
NB: I checked that nf_conntrack module is installed:
[root@plop ~]# lsmod | grep nf_conntrack
nf_conntrack_ipv6 8748 2
nf_defrag_ipv6 11182 1 nf_conntrack_ipv6
nf_conntrack 79758 2 nf_conntrack_ipv6,xt_state
ipv6 317340 28 sctp,ip6t_REJECT,nf_conntrack_ipv6,nf_defrag_ipv6
netfilter ip-conntrack
