hi,

i tried to run the chef-client in multiple nodes at a single time using roles  
from workstation for two nodes like

root@chefserver:~# knife ssh “role:webserver” “sudo chef-client”

but it shows error like on each attempt

in name resolution

WARNING: Failed to connect to – Net::SSH::AuthenticationFailed: root@ubuntu

FATAL: 2 nodes found, but does not have the required attribute to establish the  
connection. Try setting another attribute to open the connection using  
–attribute.

If you look at the logs, you will see the following,

WARNING: Failed to connect to -- Net::SSH::AuthenticationFailed:  
root@ubuntu

This is where the problem is. Can you make sure you have the correct key  
set and provide it with knife ssh.

Thanks  
Gourav

when i run knife ssh, i use a couple more options.  
here's an example:  
knife ssh -a ipaddress -x root -P password "role:sam\_app" "uptime && date"

the -a options says to use the node's ip address instead of the node's name  
or fqdn. -P passes in the root password, so i don't need to maintain ssh  
keys
