I've been playing around with IPv6 and setup a DigitalOcean droplet. The only difference between now and before is that I told it to setup IPv6. More often than not, when I run
ifconfig the SSH session hangs, then disconnects due to unresponsiveness. The
ifconfig command doesn't finish when this happens...it only gets past dumping the IPv6 details.
Any place I can check to debug this? My solution right now is just not to run ifconfig.
After reading the comments again, I realized that there is maybe a misinterpretation occurring. My command was only
ifconfig to display network details, I'm not configuring anything with it so there are no extra details beyond that.
The tip that
ifconfig isn't in use anymore is the most helpful thing so far. There is so much legacy crap on the net still, it is easy to pick up something antiquated.
