Package: dnsmasq
Version: 2.86-1.1
Severity: Serious
We have this our /etc/NetworkManager/dnsmasq.d/local-proxy:
This leads to:
dnsmasq: Bad address in --address at line 2 of /etc/NetworkManager/dnsmasq.d/goobuntu-dnsproxy
The syntax used is exactly as documented in `man dnsmasq`: /domain/server#port
Once I remove the port (#10053), the configuration "works" (except that it of course doesn't find the server to resolve the relevant requests).

This bug is actually caused by what appears to be an accidental change:
--local apparently is now an alias to --address while the manpage says it is an alias to --server.
Still a regression and/or breaking change.
Cheers,
Sven

Looking at the upstream git repo and its log, there might be other fixes
which need to be cherry-picked or we simply wait until Simon makes a 2.87
release :-)

Hi
judging from the Dnsmasq list, the problem is that --local is supposed to be an alias for --server, but the recent rewrite of the address logic apparently made it an alias of --adress instead.
If I use --server instead of--local, everything works as expected. (At least as far as I can tell.)
I can't say if the other version was also affected as we never tried that one and I won't have a chance to check for a while.
Basically, AFAICT, this boils down to:
Make --local a proper alias for --server again.
The alternative would be to update the documentation, but since this is a breaking change for existing installations, I don't think that would be appropriate.
Cheers,
Sven
