By default, ssh will try all available authentications IN ORDER (what the default order is, I'm not sure). To make sure that it doesn't try password, add the following options to your ssh command

-o 'PasswordAuthentication no'

and

-o 'PreferredAuthentications publickey'

Also, some servers and clients can be picky about permissions on the key files. Check your documentation to make sure your permissions are correct.

One other thing... It seems like it would be more secure to keep your private key at the client and put your public key on BOTH servers. Then, using authentication forwarding you can login to server A and then from server A to server B seamlessly. Remember, the strength of publickey authentication relies on being able to keep the private key private. Leaving private keys laying around on servers (especially if it's not password protected) seems like a bad idea.

NAME
nwbprm - Remove a NetWare Bindery Propery SYNOPSIS
nwbprm [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -o object name ] [ -t type ] [ -p property ] DESCRIPTION
nwbprm removes the specified NetWare Bindery Propery. nwbprm looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbprm prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -o object name The name of the object to be touched. -t object type The type of the object. Object type must be specified as a decimal value. Common values are 1 for user objects, 2 for group objects and 3 for print queues. Other values are allowed, but are usually used for specialized applications. -p property The name of the property to be removed. AUTHORS
nwbprm was written by Volker Lendecke with the corresponding Caldera utility in mind. See the Changes file of ncpfs for other contributors. nwbprm 7/9/1996 NWBPRM(8)
