Public bug reported:
Scenario:
Discovered on Kubuntu 16.10, upgraded from a fresh install of 16.04. While I
only have the one computer to test with, the 16.10 is definitely relevant (I
did not have this problem on 16.04) but I can't tell if the upgrade is part of
it, (the upgrade may or may not be relevant).
Have "full time" wired or wireless connection (does not matter which used)
Part time OpenVPN connection set up via NetworkManager.
Steps to reproduce
1. Fresh boot
2. ping a device on the VPN network (eg amachine.remotelan ) Result: "ping:
amachine.remotelan: Name or service not known"
3. Connect to the VPN service via Network Manager.
4. ping amachine.remotelan - result:
PING amachine.remotelan (192.168.68.44) 56(84) bytes of data.
64 bytes from amachine.remotelan (192.168.68.44): icmp_seq=1 ttl=127
time=7.75 ms
5. Disconnect from the VPN service again.
ping result again "ping: amachine.remotelan: Name or service not known"
6. Reconnect to the VPN again, and ping again
Observed:
"ping: amachine.remotelan: Name or service not known"
However "ping 192.168.68.44" responds successfully as expected
Expected:
PING ... 192.168.... 64 bytes from .. etc to the ping by name
---------------
Further info I'm going to add in a subsequent comment. (just annotating syslog
right now!)
