SSH without password on Ubuntu

Ssh without password | Linux4All.Net

Using the below steps, you can ssh to the server from client without the entering any password.

Run the following command on the client

-> ssh-keygen -t dsa
Enter a password here. Then when you try to connect to the accounts using SSHMenu, you will be asked for the password only once, the very first time. File id_dsa and id_dsa.pub will be created inside $HOME/.ssh

Copy the id_dsa.pub to the server's ~/.ssh directory
-> ssh-copy-id -i ~/.ssh/id_dsa.pub user@server

You can try ssh to the server from the client and no password will be needed
-> ssh user@server
Here you will be asked for the password, only once at the first time.

Create the file ~/.ssh/config, and customize your servers uniqely within it.

Host server
Hostname 192.168.170.254
User user

Now you can login with this command:
-> ssh server
