Connecting ssh from ubuntu

Question

I want to connect to ssh from Ubuntu terminal but I don't know how. I have searched it on google but I don't understand. I have an IP address, username and password. If someone can explain to me how it's done, please do. I have tried:

ssh root@ipadress

(instead of 'ipadress' from this command, of course it's the real IP address)

then it requests the password, I write it, but it keep asking for it like this:

Enter passphrase for key '.../...':
Enter passphrase for key '.../...':

The connection dates are correct because from windows, it works to connect.

I have tried this:

 ssh user@localhost
 ssh: connect to host localhost port 22: Connection refused

Answer 1

The computer you are trying to connect to, should have openssh-server running.

sudo apt-get install openssh-server will do the job for Ubuntu.

After that you can connect in that fashion:

ssh [email protected] and the server will ask for your credentials.

Where x* is your ip and user is the user you want to connect as at your server, who should have an user account in the server.

Answer 2

The key name should be something like ~/.ssh/id_rsa Try to rename it ( mv ~/.ssh/id_rsa ~/.ssh/id_rsa.back ) and try again.

This way, the ssh command will not use your key to authenticate, but password instead.

Answer 3

If find out what was the problem. I needed to do this thing:

sudo apt-get install openssh-server

and after that write my personal passphrase and just after that write the password for the connection.
