Chapter 4 Initial Configuration

3.Press ENTER when prompted for a file name for the key pair.

4.Press ENTER two times when prompted for a passphrase.

Note: If the client is a NetScaler appliance, move the private key file to a persistent location such as sub-directories of the /flash and /var directories.

5.Log on to the remote NetScaler appliance from the client by using a file transfer protocol, and perform the following:

a.Change directory to /nsconfig/ssh. At the prompt, type:

cd /nsconfig/ssh

b. Use the binary transfer mode to copy the public key to this directory.

bin

put id_rsa.pub

6.Open a connection to the remote NetScaler appliance by using an SSH client, such as PuTTY, and perform the following:

a.Log on to the remote appliance using the administrator credentials.

b.Go to the NetScaler shell.

>shell

c.At the shell prompt, change the directory to /nsconfig/ssh.

root@ns# cd /nsconfig/ssh

d.Append the public key to the authorized_keys file. At the shell prompt, type:

root@ns# cat id_rsa.pub >> authorized_keys

Note: If the authorized_keys file does not exist at the appliance, you need to first create the file and then append the contents.

e. Change the permission of the /flash, nsconfig, and ssh directories to 755.

root@ns# chmod 755 /flash root@ns# chmod 755 /flash/nsconfig root@ns# chmod 755 /flash/nsconfig/ssh

f.Change the permission of the authorized_keys file to 744. root@ns# chmod 744 authorized_keys
