Examples of netbackup restores:
      To restore files listed in a file named restore_list by using the most
      recent backups, enter the following:

      bprestore -f restore_list

At console>  halt

CFE> bye

CTRL-C to go to special boot menu

Choose option 4a to initialize disks and create a flex root volume.

system> setup

The setup command will rewrite the /etc/rc, /etc/exports,

/etc/hosts, /etc/hosts.equiv, /etc/dgateways, /etc/nsswitch.conf,

and /etc/resolv.conf files, saving the original contents of

these files in .bak files (e.g. /etc/exports.bak).

This post is really just a cut and past from a netapp manual. I need to go through this information and write a post based on it that makes sense for using ssh in scripts to performs snapshots and snapvaults on netapp.

Public-key-based authentication

Setting up key-based authentication requires an RSA key pair (a private and public key) in addition to

the host and server keys. Public-key-based authentication differs between the two versions of SSH;

SSH 1.x uses an RSA key pair and SSH 2.0 uses a DSA key pair in addition to an RSA key pair. For

both versions of SSH, you must generate the key pairs and copy the public key to the storage system.

Generating an RSA key pair for SSH 1.x

Public-key-based authentication using SSH 1.x requires an RSA key pair.

Steps

1. Using your SSH 1.x client, generate an RSA key pair.

Your client generates the RSA key pair, a public key and a private key, and stores them on the client.

2. Copy the generated public key to the storage system root volume and append it to the

/etc/sshd/user_name/.ssh/authorized_keys file.

Example generating an RSA key pair

The following is an example of generating an RSA key pair with an OpenSSH UNIX client:

% ssh-keygen -t rsa1 -b 1024

Generating public/private rsa1 key pair.

Enter file in which to save the key (/u/john/.ssh/identity):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /u/john/.ssh/identity

SecureAdmin | 163

Your public key has been saved in /u/john/.ssh/identity.pub

The key fingerprint is:

6a:c7:93:7c:b5:f4:12:87:81:56:5e:a2:62:40:07:8a john@unix1

In this example, the identity.pub file is the public-key file that you copy to the storage system

root volume.

The following commands append the public key to the

/etc/sshd/user_name/.ssh/authorized_keys file on storage system sys1:

% mount sys1:/ /mnt_sys1

% cat identity.pub >> /mnt_sys1/etc/sshd/john/.ssh/authorized_keys

Generating key pairs for SSH 2.0

Generating key pairs for SSH 2.0 requires generating an RSA key pair and a DSA key pair.

If you use SSH 2.0 clients other than OpenSSH, you might have to edit the public key before you can

use it.

Steps

1. Using your SSH 2.0 client, generate an RSA key pair.

Your client generates the RSA key pair, a public key and a private key, and stores them on the client.

2. Using your SSH 2.0 client, generate a DSA key pair.

Your client generates the DSA key pair, a public key and a private key, and stores them on the client.

3. Copy the generated public key to the storage system default directory and append it to the

/etc/sshd/user_name/.ssh/authorized_keys2 file.

Example generating RSA and DSA key pairs

The following is an example of generating RSA and DSA key pairs with an OpenSSH UNIX

client.

% ssh-keygen -t rsa -b 1024

Generating public/private rsa key pair.

Enter file in which to save the key (/u/john/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /u/john/.ssh/id_rsa

Your public key has been saved in /u/john/.ssh/id_rsa.pub

% ssh-keygen -t dsa -b 1024

Generating public/private dsa key pair.

Enter file in which to save the key (/u/john/.ssh/id_dsa):

Enter passphrase (empty for no passphrase):

164 | Data ONTAP 7.2 System Administration Guide

Enter same passphrase again:

Your identification has been saved in /u/john/.ssh/id_dsa

Your public key has been saved in /u/john/.ssh/id_dsa.pub

In this example, the id_rsa.pub and id_dsa.pub files are the public-key files that you copy

to the storage system root volume.

The following commands append the public keys to the

/etc/sshd/user_name/.ssh/authorized_keys2 file on storage system sys1:

% mount sys1:/ /mnt_sys1

% cat id_rsa.pub >> /mnt_sys1/etc/sshd/john/.ssh/authorized_keys2

% cat id_dsa.pub >> /mnt_sys1/etc/sshd/john/.ssh/authorized_keys2
