What happens if you try to ping something? Like:
It is the ping failures that give me the most angst, since I am
one of those people who, almost the first thing they'll do, if
you sit them down at a computer keyboard, is try to ping
somebody. I noticed that linode.com returned pings in a fairly
decent fashion, but godaddy.com and jtan.com returned none.
All I have to do here is click my KVM switch and set the other
unix system I have to the test. Those last two mentioned hosts
are commercial for-profit ventures, and are almost always "up,"
as was shown by my *bsd system.
I was also interested to note that linode returned pings in ipv6
mode. Switching to 'ping -4' ended any return of pings from
linode. That was the sort of thing that made me think my
"networking" was "not working."
And it's not lookup issues either, since what I see with Stretch
is like this:
PING linode.com(2600:3c00::22 (2600:3c00::22)) 56 data bytes
64 bytes from 2600:3c00::22 (2600:3c00::22): icmp_seq=1 ttl=51 time=63.4 ms

(That dotted four is one of godaddy's mail servers.)
In the middle of all this apparent network confusion, I said to
myself "Oh, the heck with it..." and started my faithful trusty
alpine mail system, which certainly requires network services.
It's been running like a charm here on my new Stretch, which is
sort of how it always runs, and I am typing on it right now and
am about to send this overlong excursion.
Thank you
