watchdog service / manage services without script.

[ianyp]

Is there a way to get the watchdog service to monitor another process / service of my choosing, or is my only option to have a script run on a cronjob schedule?

I want to run my own SSH version and want to ensure it's kept alive.

I'm guessing the answer is no and to use JFFS script, but I wanted to check I'm not missing something obvious.

Im not sure Asus watchdog allows for adding a service. Entware does support monit. Here are some ways to restart a service:

The Asus watchdog is not configurable.

The watchdog service is a custom made daemon, it doesn't rely on any config file. You will have to roll your own through a cron job and a script.

Can it be configured at all as the ddns script runs every 30 seconds

I Downloaded my system log , it goes from 00:05 til 17:14 and ran 1749 times

You can't configure the watchdog process itself as Merlin said above. But you can change some DDNS settings, like verification frequency (WAN IP and hostname verification -> Check every), depending on which DDNS service you're using.

I checked that colin and have

So why every 30 seconds

I will log this with ASUS.

What DDNS provider are you using?

I don't have the same firmware as you so I can't check it. Do you see this:



What output do you get from this command:

nvram show | grep ddns_regular

EDIT: Looking at the source code a bit more I don't think the above settings will solve your problem. I think the real solution is to fix the problem with DDNS rather than trying to change the frequency of the retries.

Has the router successfully synced with NTP?

Can you post the syslog entries covering two complete "loops" of the error messages.

 

[Wishmaster1965]

I have Wan IP and hostname verifiction Off

you query

I currently have an open case with Asus on other suprious log entries.

After checking the DDNS I will have to let it settle before i can get you the log

@ColinTaylor Turned out it was a config error on my part. I have not seen an error for the last 4 hours. Sorry for the confusion.

@Wishmaster1965 Thanks for the update. Glad to hear you got it working.
