I am confused. We connect to our instances through our proxy with a DNS name. Our proxy rejects anything that is not DNS. So if we try to SSH to an EC2 instance using IP through our proxy it will fail but will work with DNS.
When setting packer to use private_DNS is shows DNS not IP. This is what I would expect when setting it to public_DNS also but the log shows it setting it to IP. Here is an comparison of the logs using private: 2018/02/08 14:00:27 packer: 2018/02/08 14:00:27 [DEBUG] TCP connection to SSH ip/port failed: dial tcp: lookup ip-172-31-34-206.ec2.internal: no such host public: 2018/02/08 13:03:44 packer: 2018/02/08 13:03:44 [DEBUG] TCP connection to SSH ip/port failed: dial tcp 52.90.77.167:2: i/o timeout On Thu, Feb 8, 2018 at 1:34 PM, Rickard von Essen < [email protected]> wrote: > Sorry I'm not sure I follow what your problem is? > > A DNS record resolves to an IP, it is impossible "to connect to a DNS > name" > > On Feb 8, 2018 19:27, "Dayma" <[email protected]> wrote: > >> All, our proxy is only allowing us to go after DNS instead of IP.
