SSH in BatchMode

[Vikas Rawat]

> Hi All,

> We have a requirement of connecting two linux machines for executing

> remote linux machine and execute some commands. We are able to do so
> manually, but in batch mode (via scripts), we are prompted for a
> password. To avoid it, the documentation for SSH says
> 
> 1. Log in to the remote linux machine once manually, to store the RSA
> key of the remote machine. After completing the step, we cross checked
> and the key is rightly stored in /etc/ssh/known_hosts
> 
> 2. Generate the RSA/DSA keys on the client machine and copy the public
> keys on the remote machine. The public keys should be copied to a file
> ~/.ssh/authorized_keys on the remote machine. We have done this as
> well.

> 3. We have also changed the file/directory permission for ~/.ssh &
> ~/.ssh/authorized_key to be read-write for user only by executing 
> >chmod -R 600 .ssh
> 
> 4. Additionally, we have created ~/.ssh/known_hosts at the client
> machine containing the RSA public key of remote linux machine.

> As per the documentation, we should now be able to login on the remote
> linux machine without being prompted for the password. For us, we

> command on client
> >ssh -2o BatchMode=true -l <usrlogin> <remoteLinuxMachine>
> It results in 
> > Permission denied (publickey,gssapi-with-mic,password)

> Anyone has any idea on how to get through this problem.
