I've noticed my racoon.conf files reads (for example):
lifetime time 28800 secs;
lifetime time 28800 sec;
The official KAME/Racoon docs reads:
"lifetime time and lifetime byte specify the lifetime of IKE-SA. These
are by time and by bytes respectively. You can use sec, min and hour as
the unit of lifetime by time. And you can use B, KB, MB and TB as the
unit of lifetime by bytes."
So, do both "sec" and "secs" work or is that a "bug" in m0n0wall?
