Public bug reported:
dnsmasq does not resolve DNS names correcty.
Applications like Thunderbird or tools like ssh rely on working name
resolution. However, if there never was a working name resolution,
dnsmasq never gets to know about the DNS names.
Setup:
private network: 192.168.0.x/24
domain mydomain.intern
server: 192.168.0.1 hostname s1
dhcp (.100 - .200) and bind running, postfix and dovecot running
client: 192.168.0.100 (dhclient)
/etc/resolv.conf
...
nameserver 127.0.0.1
search mydomain.intern
/var/run/nm-dns-dnsmasq.conf
server=192.168.0.1
Open Thunderbird -> Thunderbird fails to open s1
ssh admin@s1 -> ssh: Could not resolve hostname s1: Name or service not known
Adding
nameserver 192.168.0.1
to /etc/resolv.conf
resolves the issue immediately
calling sudo resolvconf -u
creates the lookup problem immediately again
This is a critical error
