Creating .sh

[smaj84]

Hello,

I have created .sh file to login into remote server by using following;

# vi vpn.sh
ssh rootatremoteserverip

then I run sh vpn.sh and it asks password for this server, I want to put the password also in the script so that when I type sh vpn.sh then it won't ask password.

Any ideas.

yes.
- use ssh authorized keys
- do not remote login as root

I am using authorized key. I want to put key in vpn.sh so it will not ask me for key when I type sh vpn.sh

ok, if authorized keys login is already setup, then you might want to look into ssh-agent.

The idea is, that you give the passphrase just once (per session).

You cannot script an ssh session with a shell script.
You should use expect

Manpage of EXPECT

I am using authorized key.

I'm confused. When I use authorized keys my connection between my computer and the remote host is trusted and doesn't require a password - I thought that was the point of authorized keys?

The private key can and should be protected with a passphrase.
Otherwise anyone with that file can access your servers.

But you dont want to type that passphrase all the time.
This is where the ssh-agent comes in.
