From c63bdecd96375309d32239c7a83d985ac51704c5 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 8 Mar 2021 16:29:25 +0100 Subject: [PATCH] conntrackd: set default hashtable buckets and max entries if not specified Fall back to 65536 buckets and 262144 entries. It would be probably good to add code to autoadjust by reading /proc/sys/net/netfilter/nf_conntrack_buckets and /proc/sys/net/nf_conntrack_max.
