Hi,

I'm getting the following trying to use assh wrapper:

__$ assh wrapper ssh server

Any idea ?

Go version: go1.6.3 linux/amd64
ASSH version: 2.4.0 (via go get)

Hello,

The same error occurred.

Go version: go1.6.3 darwin/amd64
ASSH version: 2.4.0 (via brew install)

Hey guys, thank you for the report,

Can you both send me the content of your (anonymized) assh.yml file ?
I think this is due to recent changes, I probably forget to add some tests

[masa0x80]

Hi @moul, thank you for your reply.

Here's the output of my assh.yml:

hosts:
  hoge:
    User: user
    HostName: hoge.example.com

I think ASSH works well in version 2.3.0.

Fixed, I will release a new version now :)
