Title:
URI defined for connectivity check is relative to search domain
Status in network-manager package in Ubuntu:
New
Bug description:
The connectivity check URI as defined in
/usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf is not an
absolute FQDN (doesn't end in a dot). As such, resolving connectivity-
check.ubuntu.com generates queries for connectivity-
check.ubuntu.com.localdomain (assuming a common default search domain
of "localdomain") in addition to the expected connectivity-
check.ubuntu.com . Or, if your ISP provided search domain is
myisp.net, then connectivity-check.ubuntu.com.myisp.net is also
queried.
To reduce unintended traffic, may I suggest a trailing dot to ensure
the host portion of the URI is a FQDN? Ex:
uri=http://connectivity-check.ubuntu.com./

# What I expected to happen:
Sep 23 18:48:45 dnsmasq[415]: query[AAAA] connectivity-check.ubuntu.com from
192.168.0.111
Sep 23 18:48:45 dnsmasq[415]: query[AAAA] connectivity-check.ubuntu.com from

Sep 23 18:50:55 dnsmasq[415]: query[A] connectivity-check.ubuntu.com from
192.168.0.111
(requests resulting in NXDOMAIN or NODATA-IPv6 are made twice)
