Reggie: First of all, thanks for providing information about the
malfunction on your system. We will get to the bottom of this!
To get very clear on what's happening I will summarize. Let me know if
any of the following is wrong.
With the following resolv.conf (omitting comments)
nameserver 127.0.0.1
search home.lan
libc resolution of "lenin" repeatedly fails but "lenin.home.lan"
repeatedly succeeds, whereas with
nameserver 127.0.0.1
nameserver 192.168.99.2
search home.lan
both of them repeatedly succeed.
Dnsmasq listens at 127.0.0.1, configured with the following.
server=192.168.99.2
server=24.177.176.38
server=97.81.22.195
Only 192.168.99.2 can resolve the name "lenin.home.lan"; the others
cannot.
Now, what's going on here?
First I'd like to rule out the possibility of side-effects of #1003842.
Please eliminate the lines
server=24.177.176.38
server=97.81.22.195
from /run/nm-dns-dnsmasq.conf and run all your tests again. That is,
repeatedly (at least twice) try "ping lenin" and "ping lenin.home.lan"
both with only nameserver 127.0.0.1 listed in /etc/resolv.conf, and with
nameserver 127.0.0.1 and nameserver 192.168.99.2 listed in
/etc/resolv.conf. Report the results back here.
In the case where you add "nameserver 192.168.99.2" to /etc/resolv.conf
and name resolution subsequently succeeds, is there a noticeable delay?
After you have edited /etc/resolv.conf, is /etc/resolv.conf still a
symbolic link to /run/resolvconf/resolv.conf? That is, did you in fact
edit /run/resolvconf/resolv.conf as I am assuming you did?
According to resolv.conf(5) the following environment variables can
affect the behavior of the resolver: LOCALDOMAIN, RES_OPTIONS. Is
either of these set in your environment? (Run, e.g., the
env |grep '\(DOMAIN\|RES\)'
command to check this.)
