Generating key for a user

[brian_31]

There is a request to generate a ssh key for a user for testing failover on MCSG. Can someone help how to do this? The request is on the failover box.

Thanks

login as root on the primary node and copy authorized-hosts file foor the user from .ssh directory to failover node.

or

/usr/bin/ssh-keygen

and copy to primary and alternate node.

log into the server as root, on which you need to create the key
su - specific_username
/opt/ssh/bin/ssh-keygen -t dsa

when you are asked to enter passphrase, enter it (twice) if you want it to be used for authentication. If no password access is requested hit enter twice without any other keys for blank passphrase.

log out of specific_username

now you will have 2 files under ~specific_username/.shh named

id_dsa
id_dsa.pub

copy id_dsa.pub to the other node, under the same user's .ssh directory

login to the other node

su - specific_username
cat id_dsa.pub >> authorized_keys

then test it.
