Is conntrack and conntrackd still valid for CentOS 6.2? I can’t seem to find much on it any more. Is there something else to use?
Yep, conntrack is still on used mostly for netfilter/IPTables.
cd /lib/modules/$(uname -r)
find . -name \*.ko | grep conntrack
Hope this helps,
Conntrack is an important part of the system and is not going get become
“invalid” anytime soon. It’s required for NAT for example.
