Most recent distributions have PPS line support enabled by default. Still, kernel build is necessary if you have special driver requirements or change options - I recompile measurement kernels for increasing the Hz rate. The page contains some outdated information but some of it is valuable (in particular the reference to the ppstools repository and timepps.h copy that is essential for building ntp). > What version of the kernel are you using? 3.8 - 3.13 > Recent kernels need something like: > ldattach 18 /dev/ttyS0 > which creates /dev/pps0 Yes, that's what I do. Ideally you can automate it and trigger some additional ntp prerequisites (udev-related) as recommended on the ntp pps support page (http://linuxpps.org/wiki/index.php/LinuxPPS_NTPD_support) _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
