Hello everybody.
For a little project, I have two computers which need to be as best
synchronized as they could be. I tried to use ntp for that. I defined the
first one as a time server. The second one use the first one as unique
time server (I know that several time servers is recommended, but I don't
need perfect time, only perfect synchronization). When I run ntpdate on
the client, all work fery well. To achieve best synchronization, I run it
several time and it gives me precision up to 0.000001 seconds (which is
very very well). The problem is that I don't want to run ntpdate from a
cron job since I cannot have any steps (unless at run time). So I use
ntpd, but it seems not to work since the difference between the two clocks
becomes bigger and bigger.
What can be the problem? How could I solve this?
I still have to add that the two hosts have a 100Mb ethernet connection
just for them, so traffic load is not really a problem for me...
Thanks a lot for your answers.
Bruno
