Knife ssh issues


#1

Hi,

I’m trying to use knife ssh to run chef-client on demand on some servers, but it’s failing with this message:

WARNING: Failed to connect to – SocketError: getaddrinfo: nodename nor servname provided, or not known

The servers are on an AWS VPN to which I connect via VPN. Is this something that’s missing on my part, maybe knife configuration?

This often means that the node name isn’t resolvable by DNS.

You can specify an alternate attribute to use as the connection hostname
with ‘knife ssh -a’

It really is not resolvable, as it’s an internal AWS name.

Using -a solved it, thanks a lot!

Is there a way to set this (and probably -x along with it) as a default, say in knife.rb?

Thanks!

Cassiano,

You can set these values in knife.rb:

knife[:ssh_attribute] = ‘ec2.local_ipv4’ # or such
knife[:ssh_user] = ‘ubuntu’

There’s more configs, you might want to try knife-config to see them
all. http://jtimberman.housepub.org/blog/2012/03/25/knife-config-plugin/
