After having run with no problem for about a month, now every morning when I try to use the internet I can't get a dhcp lease. I've identified the problem as dnsmasq becoming inactive on the router. Starting dnsmasq solves the issue.
However this is quite annoying and I do want to know the cause of this crash. Sadly log doesn't show anything helpful. What I see though is a strange ssh connexion to frpc server on docker0.IPv4 and start of a samba service... And I use neither frpc, samba or docker. Am I victim of foulplay?
Here is an extract of the logread output:

The last error repeats ad infinitum even when all is working fine, I have to investigate if this is a related issue.
Here's the info requested. Note that there are no dnsmasq messages in log until I start it manually. When I installed openWrt I left the default docker bridge in place, perhaps I should remove it? In the meantime I have disabled the docker0 interface in LuCI; also stopped and disabled both frps and frpc.

It appears you are using firmware that is not from the official OpenWrt project.
When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.
Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).
If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.
First thing first - You are not using OpenWRT, so help here will be just to say how OpenWRT should work under your setup, which may not always beam to device manufacturer fork setup.
Your DNSMASQ works perfectly.
Your eth1 port goes down at times, without exploring reasons you can add option to save restarting all network services when that happens
config device
option type 'bridge'
option name 'br-wan'
list ports 'eth1'
option bridge_empty '1'
Thanks I will try this out. In my setup eth1 is a usb network adapter, perhaps it goes into sleep at some point.
Indeed I'm using OpenWrt-Box, a fork targetted to run on TV boxes. I thougth general openwrt function would apply here but I'll try and post on a forum relevant to that distribution.
