From 746f7031f4d1e3bccdd6db3c53835d8b85b73c90 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 17 Jan 2009 18:03:53 +0100 Subject: src: add state polling support (oppossed to current event-driven) This patch adds the clause PollSecs that changes the normal behaviour of conntrackd. With PollSecs set to > 0, conntrackd polls every N seconds the entries. This is the opposed behaviour of an event-driven behaviour but may be useful for those that have really strong limitations in terms of CPU consumption and want to perform a relaxed replication.
