From 7ae244a26ef516511a5e476dd14ec033501a1d8d Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Thu, 20 Apr 2017 16:55:29 +0200 Subject: luci-mod-admin-full: use `nf_conntrack_count` for counting connections (#1114) As suggested by PR #1114, use `/proc/sys/net/netfilter/nf_conntrack_count` instead of counting the lines in `/proc/net/nf_conntrack` but use a slightly more efficient approach which avoids spawning an extra `cat` command.
