ASUS RT-N66U Time settings and local NTP-server

[FireWire76]

Hi.

Last night I lost my WAN-connection due to some problem with my ISP. I made a router reboot and noticed that the router time settings reverted to January 1st 2007 and time was set to 00:00:00. Haven´t even thought about this before, but firstly why is there no way of manually set time and date?!?! And second, why isn´t it possible to set a local NTP-server? I typed in the IP(also tried my computers hostname) of my main computer(it is set up as a local NTP-server with Windows time running 24/7, to serve as server for all network devices that isn´t allowed to access the internet). But the router didn´t seem to be able to use this setting, at least as long as WAN was down.
When WAN came back, the router somehow updated time and date even though I had my computers host name typed in. Why isn´t that working when WAN is down?
Hope you can help out here Merlin, would be nice to be able to both use a local ntp-server for the router. And regarding manual adjustment of time/date, isn´t that something that should be standard in a router?

Best regards,
FireWire

The date will always revert to January 2001 after a reboot because the router has no realtime clock. You can manually set the time and date using the "date" command over telnet/ssh.

The ntpclient only runs when there is a WAN connection, that's why it won't be able to use a LAN NTP server. Since almost no one but businesses with a domain controller run their own NTP server, this isn't something worth the development effort. You can easily work around this by running ntpclient from a user script, having it manually connect with your LAN NTPD.

Explains why the time is never saved after a reboot.

Thanks for the info.

It only stays that way for a minute though, then it does check with the ntp-server and the time is configured properly once again.

Can you help guide me on how to set up such script? Consider me being a 'dummy'. I don´t know anything about scripts. Would really appreciate your help.

Sorry for bumping an old thread but it's relevant to this thread.

I used ntpclient -h <ip of ntp server>, but the time came out 4 years and some change off. I know the NTP server is working ok because my Shibby RT-N66U updated perfect.

Tomato:
root@RT-N66U-VPN:/tmp/home/root# ntpc 10.0.1.10
Trying 10.0.1.10:

setup_transmit:: connect...

send packet OK!

fixed it with:
ntpclient -h <ip> -s

1- You will need merlin firmware with enable sshd server.
2- See this merlin info on how to create scripts

3- See this info as a pratical example on creating a real life script

4- To easily deal with creating scripts, you will need under windows winscp (this allow to edit scripts with a window editor an easily change files in the router by using your router login name/password (create an scp connection to router ip lan address using your router web login info)

5- An usb key connected to the router helps to allow saving things there, even if the router firmware if updated later (if file security concern is not a problem to you)

Hope this helps
