What is the earliest script where the LAN (not WAN) will be up?

[cmkelley]

I have a separate time server on my network so if the LAN comes up before the WAN I can update the time from it at the earliest opportunity. I've read https://github.com/RMerl/asuswrt-merlin/wiki/User-scripts, but it doesn't really say which of those is "first". It's got a static IP so I don't need any DNS services.

Does the LAN even come up before the WAN? Is a loop in init-start the best way?

I wouldn’t go with a blocking loop (as there is a 120 second execution time limit on the start scripts), but a forked/demonised script spawned from init is probably your best bet.

The earliest script called is init-start but even though it executes early it may not be early enough.

As far as I can tell, the LAN is not up when init-start runs. Judging by the fact that there is a wan-start script, the WAN isn't.

My google-fu is weak today, it took me far too long to find https://www.snbforums.com/threads/chronology-of-the-execution-of-user-scripts.9410/

Not quite what I was looking for, but it hints that wan-start might be a good place. It just kinda annoys me wife when I keep rebooting the router to test this stuff ...

Maybe this would save you some time so your not doing a full reboot ??? https://www.snbforums.com/threads/wan-connect-and-disconnect-using-script.11232/#post-70114

Edit: Same here with the mrs. and restarting the router.

Just use fake-hwclock?

Well, I am, but, @bbunge opined (https://www.snbforums.com/threads/stubby-installer-asuswrt-merlin.49469/page-24#post-457426) that may not be enough. So I thought it's silly to go out to the internet for time when I have a hyper-accurate gps-synced ntp server (yes, I'm a nerd!) on my network. I'm just looking to see what the earliest I can directly query it is.

Good to know, but the idea is to find out how early in the boot process I can access my local ntp server, so actually rebooting is required.
