Yesterday I had to revert to a recent snapshot of my vm. This vm was working flawlessly at the time I took it.
But now I can no longer resolve any url from this host. All git pull commands, all curl requests, host lookups, etc.. are failing. For instance:
host www.google.com ; connection timed out; no servers could be reached
Yet this host is reachable from the outside world, as I can ssh to it, and http requests coming in are being serviced.
What am I forgetting?
