Reopen Issue

Hello.

As I want to debug some issues on arm build, I want to access arm machine, however 

$ ssh -vvv -i .ssh/id_rsa_fedora mtasaka@arm03-qa01.cloud.fedoraproject.org

fails as below. Would you investigate this?

Could you provide the output of "ssh-add -L"?
These are the public SSH keys that are active in your agent.

Here:

$ ssh-add -L

Ah, the documentation is incorrect.
You are supposed to use arm03-packager00.cloud.fedoraproject.org and arm03-packager01.cloud.fedoraproject.org Instead of arm03-qa0{1,2}.

Ah, okay. I can log in to arm03-packager01.cloud.fedoraproject.org . However arm03-packager00.cloud.fedoraproject.org is dead?

(does not return)

Yep. That machine was down. I have power cycled it and it's back up now. ;)

Thanks for letting us know.

If there's incorrect docs somewhere, please do fix them. The -packager ones are intended for packagers and the -qa ones are inended for qa members.
