Question How can we ssh login with script?

Hi all,

Normally, we give ip address to login with ssh like ssh 172.168.0.1
And we can give login name to ssh like ssh -l root 172.10.0.21
Then the shell asks the password, we enter the password and login to the system.
While using the script file, we are not able to supply the password to the shell.

Is there any option to provide user name and password to the ssh command in a single line?
OR
Is there any option to give password in next line script?

plz help me,
Thanks and regards,
P C Saji

you need to create keys
swap them across servers
set the permission

man ssh-keygen

You can setup ssh keys. Here is a link to a decent tutorial on how to do it.

Another option is using "expect".

Here is an example of an expect script:

I am trying to do the same thing, But in this case, I want the key to be generated for the local machine, coz i need to be root to run a few commands.

Can some one please assist me with this ?

Thanks

to enable ssh between servers,
you need to generate keys,
public keys to be exchanged under appropriate directory of the server.

And none of the commands do need root privilege

do let us know about the commands that you are trying to execute to setup above ssh-settings that requires root privileges !!! Smilie Smilie Smilie
