Dec 13, 2017 · 5 DNS requests + 1 NTP update according to the article (seems weird that it would resolve all the the NTP servers, but lets roll with it) DNS: dig
OpenWRT’s NTP client already synchronizes with the NTP pool, so making it also act as a NTP server for internal clients is ideal. OpenWRT’s default client is the busybox NTP client, which can also act as a server – no need to install additional packages! Any such-configured NTP server certainly can serve as a backup for local timekeeping when Internet connectivity is not available, but should never be advertised on the Internet as a Stratum 1 clock. Proper GPS synchronization uses a PPS output (or similar) from the device, fed directly into an interrupt-generating line, for example a GPIO or Jan 06, 2016 · Check Enable NTP client and Provide NTP server. This is to configure the router to act as a NTP forwarder. Pick your servers; pool.ntp.org is a popular option but Malaysia seems to have (at time of writing) just one NTP server in the pool. This is fine if it is always working, unfortunately not. OpenWrt will try the specified hosts in order, and use the first one that is responding to time requests. OpenWrt uses the NTP Pool to locate a close-by time server. These are the default hosts: In your OpenWRT Console, go to Network, Interfaces, then go to LAN (Or the Interface you want to add this option to), then click Edit. Go to DHCP Server, Advanced Settings and add the lines below, each item needs to be added to an individual line, the IP address on the line below of 192.168.1.1 would be your router's IP address.
Jul 24, 2020 · The number of NTP pool server IPs is 3,758 (1,028 IPv6 and 2,730 IPv4) distributed across 97 economies and regions around the world. They are mainly concentrated in economies with well developed networks, such as the United States, Germany, France, Britain, and the Netherlands. Together, these five economies account for 55% of NTP servers.
Many, but not all, Network Time Protocol (NTP) servers also serve Time on port 37. There is a list of NTP servers here  The National Institute of Standards and Technology (United States Gov't) offers about a dozen Time servers to the public. Their server list is available here  Here is a list of working servers (at this moment): Download ntpdate_4.2.8p11-1_x86_64.ipk for OpenWrt 18.06 from OpenWrt Packages repository. the system clock with remote NTP time servers and run/monitor local NTP Jul 24, 2020 · The number of NTP pool server IPs is 3,758 (1,028 IPv6 and 2,730 IPv4) distributed across 97 economies and regions around the world.

Servers should use UTC in order to simplify server management; especially when you are managing resources across multiple time zones. Furthermore ntp knows nothing about time zones, ntp strictly deals in UTC.
NTP on 301-moved.de You may have reached this site because you followed an IP address that points to one of my public NTP servers. If you see traffic on Port 123/UDP on your firewall/router towards one of the listed IP addresses below, these devices are using the public NTP pool for time synchronization. Note: A time server is hard-coded into the DD-WRT firmware. If you enable the NTP Client (that's the default setting) but leave the Server IP/Name field blank, your router will synchronize anyway. One forum poster has reported a time server (ntp2.usno.navy.mil) in his config file. Brainslayer is mum on the issue. Time Servers The ISC ntp suite is a collection of tools used to synchronize the system clock with remote NTP time servers and run/monitor local NTP servers: OpenWrt Packages x86_64 Official: ntpd_4.2.8p13-3_x86_64.ipk: The ISC ntp suite is a collection of tools used to synchronize the system clock with remote NTP time servers and run/monitor local NTP servers That returns all the ntp servers in one long string fine. 0.openwrt.pool.ntp.org 1.openwrt.pool.ntp.org 2.openwrt.pool.ntp.org 3.openwrt.pool.ntp.org I wish to achieve the same (or equivalent) using the C api. I put together the following code: Sep 25, 2018 · In OpenWrt, time is automatically synced from external NTP servers during boot. Let's configure Tor, the /var folder is mounted as tmpfs in openwrt, I'm using a bit different configuration than usual, storing the Tor related data in /etc/tor/data folder instead of default /var/lib/tor folder. It has at-least two advantage, OpenWRT uses Dnsmasq as its default DNS forwarder and DHCP server. It is also has a built-in TFTP server.. Dnsmasq allows you to host the TFTP files on your router. The configuration for this scenario is as follows using /mnt/storage/tftp as the location for the TFTP files: root@OpenWRT:~# ntpd -w -p localhost ntpd: timed out waiting for 127.0.0.1, reach 0x00, next query in 2s running the netstat -l command, NTP server is only listening on IPv6: udp 0 0 :::ntp :::* (The server does not respond on IPv6.)
