I'm learning "startup engineering", encountered this error when using ssh alias. Below is the detailed steps (executed in Cygwin windows 8):

$ mkdir -p ~/.ssh $ cp ~/downloads/skey.pem ~/.ssh/ $ chmod 400 ~/.ssh/skey.pem $ chmod 700 ~/.ssh $ nano ~/.ssh/config $ cat ~/.ssh/config Host awshost1 HostName ec2-54-218-35-71.us-west-2.compute.amazonaws.com User ubuntu IdentityFile "~/.ssh/skey.pem"

Then I ran below command

ssh awshost1

But it prompts

ssh: Could not resolve hostname awshost1: hostname nor servname provided, or not known

And the verbose output:

$ ssh -vv awshost OpenSSH_6.2p2, OpenSSL 1.0.1e 11 Feb 2013 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 ssh: Could not resolve hostname awshost: hostname nor servname provided, or not known

Would anyone please help me on this? Thanks.

As you can see from the output, your ssh-client reads /etc/ssh_config, not ~/.ssh/config. Try to connect like that: ssh -F ~/.ssh/config awshost1.

you can run ssh-host-config

and place your ssh config in /etc/ssh_config which will make it work flawlessly

In my situation I found cygwin didn't install its own version of openSSH by default.

When I run in cygwin terminal

 ssh myServer

The Windows' ssh is running and it looks for config file under

 c:\users\computerName/.ssh/config

This is solved by running cygwin setup setup-x86_64.exe and adding openssh
