适用于github的Mac vs Linux（Ubuntu）.ssh配置

Question

I have following configuration on Mac OS X in /Users/andi/.ssh/config :

Host github
    HostName github.com
    IdentityFile "~/.ssh/githubik"
    IdentitiesOnly yes

And I easily can run easily git clone git@github:andilab/mbf.git

I try very same configuration on Ubunut (14.04 on EC2). The config is in /home/ubuntu/.ssh and wwhen I run git clone git@github:andilab/mbf.git I get:

Cloning into 'mbf'...
ssh: Could not resolve hostname github: Name or service not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Answer 1

all right I know it sucks answering own questions on SO, but maybe it will help somebody. I was sudo-ing on server, so the configs for ubuntu user were not considered when playing as root .

Solution : provide configuraiton for right user, and everything works.
