ping: UDP connect: No route to host
PING www.google.com (216.58.212.100): 56 data bytes

round-trip min/avg/max/stddev = 85.487/87.865/90.243/2.378 ms
That's interesting - ping6 was merged into ping last year, the basic
https://cgit.freebsd.org/src/tree/sbin/ping/main.c#n128
1. IPv6 disabled? Use IPv4
else
2. IPv4 disabled? Use IPv6
else
3. do hostname lookup and decide based on the AF of the first result.
As far as I can tell, the result of 3. is not used for the ping
though, but only to decide if ping6 or ping should be done. I
wonder if this is actually a good idea - gut feeling-wise I would
prefer only one lookup to take place when calling ping.
jexec client ping -6 -c 2 www.google.com
I assume that should give you some output (including an IP address),
even though the ping6 itself will fail.
Also, what is your /etc/resolv.conf inside the jail?
I suspect that the problem is caused by the gethostbyaddr call in 3.
and is not directly IPv6 related - if I compare the code used by
ping.c and ping6.c (including capsicum support) with what 3. does,
we might have a bigger problem here.
Best,
Michael
