Hi!
When not running as a daemon (--daemon option), OpenVPN writes all
output to stderr. When OpenVPN isn't run interactively, but it actually
isn't run with the --daemon option as well, it's rather inconvenient
that syslog isn't used. This is primarily an issue for the development
of a VPN appliance I'm working on
(http://adsl-dc-3b681.adsl.wanadoo.nl/vvpn) but if for example OpenVPN
would be controlled by inittab the same problem is there.
Attached a patch that solves the problem for me, it may be of use to
others as well.
Cheers!
Rolf
