When you do a fresh (re)start, openvpn complains because "certificate is not yet valid". My patch allows to have a good enough date early in the boot process, so openvpn can connect right away (and doesn't need to wait until ntpd sync) and if for some reasons busybox ntpd can't sync time, my vpn still work In the past, when openwrt was using rdate, it happened me once to be stuck outside ntpd is pretty reliable but i prefer to have a backup plan (i'm planning to rely much more on my vpn) In summer I can have many small power loss by day, so i don't want to wait each time for ntpd to sync for openvpn to connect In general if you use certificates you need "good enough" time, so you have to wait after ntpd sync. 30 days is the default save interval, in order to not write too often, but you can put a smaller value (1?), or run "/etc/init.d/sysfixtime save" when needed (when you renew/change your openvpn certificate, ...) > > if you only safe the the time every 30 days your clock is > wrong anyway. we played with this idea already and use now > the "crashlog" for keep time over reboot, but i'am not > totally happy with this solution for now. > > bye, bastian bye, etienne _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
