Hi, Ping times seem OK to me, they are under 90ms, and jitter is less than 1ms.
The 4000ms is total time taken, for 5 packets, and is constrained by (1 sec per ping) * (n-1) attempts. My values are: --- ntp1.inrim.it ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 394.250/430.628/491.200/39.994 ms .. and I am synchronised to it, quite well. -- Sanjeev Gupta +65 98551208 http://www.linkedin.com/in/ghane On Wed, Oct 10, 2012 at 3:20 PM, IT2GO <[email protected]> wrote: > I've already tried, but still ping times to South Europe are very high as > you can see > > --- ntp1.inrim.it ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 3999ms > rtt min/avg/max/mdev = 70.954/72.383/74.783/1.393 ms > > --- ntp2.inrim.it ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 4000ms > rtt min/avg/max/mdev = 87.282/87.879/88.444/0.542 ms > > --- ptbtime2.ptb.de ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 4001ms > rtt min/avg/max/mdev = 89.815/90.649/91.792/0.723 ms > > --- ntp2.linx.net ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 3998ms > rtt min/avg/max/mdev = 141.649/142.121/142.602/0.393 ms > > --- ntp2.rrze.uni-erlangen.de ping statistics --- > 5 packets transmitted, 5 received, 0% packet loss, time 3997ms > rtt min/avg/max/mdev = 65.639/66.055/66.524/0.346 ms > > > > > > > Op 10/10/2012 6:53, Sanjeev Gupta schreef: > > On Wed, Oct 10, 2012 at 7:31 AM, IT2GO <[email protected]> wrote: > >> Dear, >> >> I've got a server in Egypt (s01.eg.it2go.eu) and i would like to install >> a NTP server on it.
