> Or you can ask the it guys to use a windows server... Eg: > > http://support.microsoft.com/kb/816042 That is a joke Jared? You left off the smiley. Windows doesn't do NTP out-of-the-box (Microsoft assertions to the contrary notwithstanding). You can build a reasonably working standard daemon, however don't expect time to be very accurate. Windows out-of-the-box can keep time +/- 10 minutes or so using the Microsoft lets-pretend-NTP. You can build the current standard NTPD distribution on Windows. You can also spend lots of time to make it "work as well as possible" (once you manage to get it to compile, that is). Even so, when you have configured it to the optimality of accuracy, this is what you can expect: remote refid st t when poll reach delay offset jitter ============================================================================== +tic.nrc.ca .PPS. 1 u 13 64 377 55.544 5.913 0.870 -tac.nrc.ca .ATOM. 1 u 48 64 377 56.188 4.768 3.041 -toc.nrc.ca .ATOM. 1 u 1 64 377 55.485 4.758 0.981 +tick.usask.ca .GPS. 1 u 34 64 377 19.566 6.942 5.699 *tock.usask.ca .GPS. 1 u 29 64 377 19.665 5.955 1.937 -clock.isc.org .GPS. 1 u 37 64 377 53.091 8.311 0.649 +clock.sjc.he.ne .CDMA. 1 u 48 64 377 43.591 6.066 2.501 offset: 0.005955 s frequency: 23.346 ppm poll adjust: -30 watchdog timer: 47 s is about the best you will get.

Hardly any I/O, just a simple function it does. http is a frilly pink bauble, not a management necessity. Very basic linux with no frilly bauble's, ntpd, sshd, and vi. Supports thousands of clients on a $10 80286 with 640KB RAM booting from a floppy. Add $1000 and you can get the same thing as an "appliance". --- () ascii ribbon campaign against html e-mail /\ www.asciiribbon.org

http/ssl to dropbox.com dying
by Greg Ihnen 30 Jun '12

30 Jun '12

From other geographic locations I can connect to the dropbox service and get to their https web page, but from my home connection I can't, unless I vpn around the issue. downforeveryoneorjustme says it's just me, but they're located someplace else geographically, and I don't know if they check the https site. http://www.dropbox.com immediately redirects to https://www.dropbox.com It seems like a transport issue. Is there any tools for checking where an https connection is failing, like a traceroute for https? I'm not sure if the traceroute results are indicative but here it is Macintosh-2:~ gregihnen$ traceroute dropbox.com traceroute: Warning: dropbox.com has multiple addresses; using 199.47.216.179 traceroute to dropbox.com (199.47.216.179), 64 hops max, 52 byte packets 1 router (192.168.7.1) 1786.458 ms 1.670 ms 2.072 ms 2 modem (100.42.12.241) 1644.717 ms 2031.032 ms 2113.805 ms 3 75.7.64.12 (75.7.64.12) 2594.284 ms 1650.347 ms 822.159 ms 4 75.7.64.2 (75.7.64.2) 1528.550 ms 2168.641 ms 1922.285 ms 5 12.91.131.205 (12.91.131.205) 2323.903 ms 3137.965 ms 2138.427 ms 6 cr83.cgcil.ip.att.net (12.122.133.202) 1629.569 ms 1946.842 ms 1621.351 ms 7 cr1.cgcil.ip.att.net (12.123.7.110) 2256.595 ms 1515.060 ms 2418.845 ms 8 gar8.cgcil.ip.att.net (12.122.133.161) 2349.706 ms 2339.392 ms 583.224 ms 9 192.205.37.150 (192.205.37.150) 1396.288 ms 1732.779 ms 2664.270 ms 10 4.69.158.138 (4.69.158.138) 2690.646 ms 4.69.158.130 (4.69.158.130) 2313.195 ms 4.69.158.138 (4.69.158.138) 1261.560 ms 11 ae-3-3.ebr2.denver1.level3.net (4.69.132.61) 1476.892 ms 1819.138 ms 2188.664 ms 12 ae-1-100.ebr1.denver1.level3.net (4.69.151.181) 1490.142 ms 2916.895 ms 2569.848 ms 13 ae-3-3.ebr2.sanjose1.level3.net (4.69.132.57) 4328.125 ms 3226.550 ms 2648.859 ms 14 ae-72-72.csw2.sanjose1.level3.net (4.69.153.22) 2171.863 ms ae-82-82.csw3.sanjose1.level3.net (4.69.153.26) 2675.059 ms ae-92-92.csw4.sanjose1.level3.net (4.69.153.30) 4404.724 ms 15 ae-1-60.edge2.sanjose3.level3.net (4.69.152.17) 3331.595 ms ae-2-70.edge2.sanjose3.level3.net (4.69.152.81) 3112.938 ms 2492.688 ms 16 * * * 17 * * * 18 * * * 19 * * * 20 * * * 21 * * * 22 * * * 23 * * * 24 * * * 25 * * * 26 * * * 27 * * * 28 * * * 29 * * * 30 * * * 31 * * * 32 * * * 33 * * * 34 * * * 35 * * * 36 * * * Greg
