hi, got a real serious issue with net::ssh again,

I’ve bought a new slice from slicehost running Ubuntu Gutsy 7.10, and  
i’ve setup ssh to work fine via…

scp ~/.ssh/id\_rsa.pub root@myipaddress:~/

once copied to the server, i move it into the .ssh directory disconnect  
and try ssh from my local machine, all fine

now when i try to connect via capistrano, to make it use the new server  
it keeps popping up with…

Net::SSH::AuthenticationFailed: indiehead  
from  
/usr/local/lib/ruby/gems/1.8/gems/net-ssh-1.1.2/lib/net/ssh/session.rb:143:in  
`initialize' from /usr/local/lib/ruby/gems/1.8/gems/net-ssh-1.1.2/lib/net/ssh.rb:47:in `new’  
from  
/usr/local/lib/ruby/gems/1.8/gems/net-ssh-1.1.2/lib/net/ssh.rb:47:in  
`start’  
from ssh.rb:6

I’m trying…

require ‘rubygems’  
require ‘net/ssh’  
include Net  
domain = ‘[mydomain.com](http://mydomain.com)’ # insert IP address or domain name here  
begin  
Net::SSH.start( domain ) do |ssh|

# …

end  
rescue Net::SSH::HostKeyMismatch =\> e  
puts “remembering new key: #{e.fingerprint}”  
e.remember\_host!  
retry  
end

which usually works but this time it doesn’t want to know, any ideas?

i’m using port 22 so nothing’s out of the ordinary, the app is on  
another box so i’m trying to migrate it to the new slice.

appreciate any help with this, tried for hours yesterday, got nowhere.

John.

Hello John,  
You made your key to connect to root@myipaddress but forgot the  
username in your script so it is attempting to connect to  
indiehead@myipaddress instead.

You can specify the username as the second parameter to the Net:SSH  
call.

Net::SSH.start( domain, ‘root’ ) do |ssh|

Likewise in your actual capistrano recipe, you would want to add:  
set :user, ‘root’
