Hi!
I'm running a soekris net4801 with openwrt 10.03. kernel 2.6.32.10 with
LinuxPPS patch and ntpd 4.2.6p1.
Today I recognized that my /dev/ttyS1 gets a input buffer as soon as I run
ldattach PPS /dev/ttyS1
The buffer is hold until somebody connects to /dev/ttyS1 and reads it. This
is reproduceable with "cat" at any time.
ntpd gets confused by the input at start big time and needs really long to
settle.
I have not found the cause of this yet. Has somebody noticed similar behaviour?
Greetings, Wolfgang
NTPD has always needed a long time to settle. From a cold start you
need to wait ten to twelve hours for the time to reach the best possible
accuracy! This is not a great problem if you keep NTPD running 24x7.
For those who need/want to turn NTPD on at 0830 local time and turn it
off at 1700 local it's a real problem to which the only solutions are:
to suffer, to run 24x7, or to use a tool better suited to the circumstances.
