Hi there,
I am having some problems related to DNS. Clients of some nodes can
reach the Internet but cannot resolve names.
I do not know how DNS work in LibreMesh.
If I check the DNS settings of a client I see the anygw address as the
DNS server.
How does name resolution of Internet hosts work in LibreMesh? I mean
when the LiMe network has access to the Internet.
If there is a router sharing their Internet connection with a LiMe
network and it changes the configuration of its DNS servers,
will the LibreMesh network be affected by that change?
How?
Will the problem be automatically solved after some time?
Do I need to manually restart any service?
Thank you.

I forgot to write that the router sharing its Internet connection keeps
resolving names without a problem.

Sorry, I was wrong. What I see it's the local host itself (127.0.0.1).

if not, please provide details of which names cannot be resolved, and
what's the error
ideally, provide the output of something like
$ dig +all google.com
and, why not, also
$ dig +all google.com @8.8.8.8

Thank you Gui. It is not solved. I do not have access to the network
now, I will provide those details when possible.
But I guess the main problem here is my lack of knowledge on DNS, I do
not know how LiMe clients resolve names.
When a LiMe node leases a DHCP address, does it also provide a DNS
server (DHCP option 6) so that clients can resolve names?
If so, is that DHCP option 6 inherited from the Internet gateway?

Yes, the LiMe node proposes itself as DNS server, this is needed if you
want to resolve internal IPs like thisnode.info or somehostname.lan
If so, is that DHCP option 6 inherited from the
Internet gateway?
The LiMe nodes uses some fixed external DNS servers for resolving
external domains.
https://github.com/libremesh/lime-packages/blob/develop/packages/lime-syste…
Which right now are set to:
list resolvers 4.2.2.2 # b.resolvers.Level3.net
list resolvers 141.1.1.1 # cns1.cw.net
list resolvers 2001:470:20::2 # ordns.he.net
I don't think there's an option for taking the DNS suggested by your
ISP, there's also an open issue on this:
https://github.com/libremesh/lime-packages/issues/95
Bye!

Brilliant. Thank you. That's the info I needed.
Our network is degrading somehow, now we do not have DNS issues but
Internet connectivity issues, so I will open a different thread.
