To resolve this issue, log off from and then log back on to the computer. If this issue persists after you log off and then log back on, follow these steps. FULLY COMPATIBLE WITH macOS Catalina (10.15). The real true bidirectional synchronization tool! Many other synchronization apps here use the Unix tool rsync to do their job but they can't offer bidirectional sync. Ask them before buying, you'll see! File Synchronization synchronizes multiple pairs. The program’s underlying two-window technology enables parallel work in two file windows. Files and directories are displayed on both sides in a clear tree structure. Additional file windows can be attached as tabs. As usual with Windows Explorer, you can perform file operations conveniently by dragging and dropping files, using the menu bar or the context menu. Ntpdate -b pool.ntp.org results: 30 Dec 03:00:10 ntpdate1341: no server suitable for synchronization found The ntpdate debug flag which is -d will show debug data but not actually sync, and that works: ntpdate -d pool.ntp.org results: 30 Dec 03:00:55 ntpdate1343: step time server 128.10.254.6 offset 228.030338 sec – Crash Override Dec 30. The 'Time server sync' tab on the System Time page allows ntpdate, if it is present, to be run periodically, probably via cron. This functionality is redundant under TurnKey Linux which configures ntpd to set the time at boot and sync it ntp.ubuntu.com or other servers thereafter. The 'Time server sync' tab should probably be hidden.
![]() Followed your instructions, here's the output: How do you connect to the Internet? From looking around the Internet, it sounds like your problem is a blocked port. Make sure the firewall is turned off on your computer. And make sure that if you have a router/firewall for Internet sharing, that its firewall is allowing UDP packets through. It should connect to the time server (at Apple) on port 123. The connection back will be to a higher number port, it was around 55900 on my iMac just now. Here's how I figured how which port: I opened Terminal again, but this time opened two windows. I the first one, I typed this: <pre>sudo tcpdump -i en0 port 123</pre>Again, I had to give my admin password. I get a couple of lines, then it just sits and waits: <pre>tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en0, link-type EN10MB (Ethernet), capture size 96 bytes</pre>Then, I switched to another Terminal window and entered a slightly different command: <pre>ntpdate -d -q time.apple.com</pre>The options here are this: -d gives enhanced debug output and -q just queries the server but doesn't actually set the time (so I don't need to use sudo). When I run that command, I get a bunch of lines in the other window where tcpdump is waiting: <pre>19:29:26.551255 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:26.590860 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:26.591003 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:26.628405 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:26.628509 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:26.661951 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:26.662055 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:26.697510 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:26.751198 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:26.786127 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:27.751223 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:27.784616 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:28.751239 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:28.785549 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48 19:29:29.751219 IP iMacName.local.55915 > time0.apple.com.ntp: NTPv4, Client, length 48 19:29:29.784047 IP time0.apple.com.ntp > iMacName.local.55915: NTPv4, Server, length 48</pre>You can see in that example that it actually connected to the NTP server at apple on the NTP port time0.apple.com.ntp. But it connected back to my computer on port 55915: iMacName.local.55915. It would be interesting to see what your computer says. (Just rename the local computer's name if you want, but make sure the port number is still there). To stop tcpdump waiting for network traffic, just hit the control-'c' key combination. Finally, one more suggestion, try adding a longer timeout to the ntpdate command you tried earlier: <pre>sudo ntpdate -t 4 time.apple.com</pre>The default timeout on OS X is 1 second, so maybe setting to a higher value will help. charlie No Server Suitable For Synchronization Found Macos DownloadComments are closed.
