Well, when i execute
puts ssh.exec!('ssh -t user@host ls -la /root')

It gives:
Pseudo-terminal will not be allocated because stdin is not a terminal.
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-with-mic,password).

After i google around and execute this
puts ssh.exec!('ssh -t -t user@host ls -la /root')

It gives:

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-with-mic,password).

Seems like it's requesting password. How do send passsord?
